Well logging, or borehole logging, creates an in-detail record of the geologic configuration that has been penetrated by a borehole. This record is called a well log. There are two types of well logs. Geological logs are compiled by visually examining samples obtained from within the borehole. Geophysical logs are based on the measurements gathered from instruments that were lowered into the borehole. Both types are referred to as either measuring while drilling (MWD) or logging while drilling (LWD). The effective interpretation of well log results requires MWD training and MWD technical support.
There are types of geophysical well logs that can be performed at any time during a well bore, including the drilling, completing, producing or abandoning phases. MWD is common in directional drilling boreholes that have been drilled for oil, gas or groundwater. They are also valuable when conducting mineral and geothermal explorations or geotechnical and environmental studies.
The History of Measuring While Drilling
Marcel and Conrad Schlumberger, the 1926 founders of Schlumberger Limited, are recognized as the inventors of electric well logging. Conrad devised a method of prospecting for metal ore deposits called the Schlumberger array, which was a surface technique. The two brothers then modified that technique for subsurface use. In late 1927, one of the Schlumberger crews put an electric tool down a well in Pechelbronn, Alsace, France, which resulted in the first well log. Nowadays, that initial log would be referred to as a resistivity log or a 3.5-meter upside-down lateral log.
Two Schlumberger employees in 1931, Henri Doll and G Dechatre, noticed that a galvanometer reacted even though there was no current passing through the logging cables within the well. Their discovery led to the development of a process that could differentiate between impermeable nonproducing beds and permeable oil-bearing beds by measuring the spontaneous potential (SP). The SP was a natural reaction at the edges of permeable beds by the borehole mud. When the SP and resistivity were recorded concurrently, loggers were able to see if their well bores would be successful.
The Schlumbergers devised the spontaneous potential dipmeter in 1940. It permitted the calculation of the dip and the direction of a layer’s dip. This led to the resistivity dipmeter in 1947 and the continuous resistivity dipmeter in 1952.
During 1948, oil-based mud (OBM) was initially used at Rangely Field in Colorado. Electric logs need water-based mud. However, OBM is not conductive. This problem was solved by the induction log in 1949. In the 1960s, new transistors and integrated circuits improved the reliability of electric logs.
The computerization seen in the 1970s enabled speedier log processing, which expanded the ability to gather log data. Resistivity logs and porosity logs, called combo logs, could be recorded simultaneously in the borehole.
Today, MWD rental kits enabled companies to make use of this technology without investing in the hardware singulair medication. These kits included accelerometers, magnetometers and gyroscopes. More advanced MWD kits use temperature, pressure and strain gauges along with gamma ray sensors to measure mudflow volume, downhole temperature, bit torque, bit weight, drillstring rotation and the severity of downhole vibration.
An onboard logic unit processes the collected data and converts it into binary code. That code is then transmitted to the surface by Mud Pulse Telemetry (MPT). Depending on the binary code, a Pulser Unit varies the drilling fluid pressure accordingly. Fluctuations in pressure are converted into usable data on the surface.
Improvements to existing MWD kits and modern technology are continuously advancing the ability to measure while drilling. Real-time data enables faster decisions during the well bore. In some cases, video cameras are also being effectively employed in the process.
The cost of oil extraction has gone down significantly in recent years singulair over the counter. Advances in drilling technologies have led to the extraction of oil from areas once deemed too unprofitable or unproductive to explore. Measurement-while-drilling (MWD) techniques provide real-time information to operators, allowing them to make rapid adjustments to drilling approaches on the fly. Additionally, the technologies used to extract petroleum from oil shale reserves have been fine-tuned and adjusted to ensure the most efficient production in these areas. MWD training programs are becoming more prevalent throughout the industry, allowing companies to make the most effective use of available resources to increase profitability and production from new and existing wells. Here are some key insights into the current costs of shale well drilling operations.
Cost Reductions Across the Board
A 2016 report from the U.S. Energy Information Administration indicates that the average cost of drilling an oil or gas well has fallen steadily since 2012. This decline in overhead expenses has affected both the drilling cost per lateral foot and drilling costs for the entire depth of an oil well. Hard figures put this decrease in costs into perspective:
- Permian Basin – Delaware Basin well costs fell by $1.4 million between 2014 and 2015.
- During the same time period, Permian Basin – Midland Basin costs fell by half a million dollars.
- The cost of Bakken wells fell by $1.2 million between 2014 and 2015.
This overall reduction in costs can be traced to a number of key factors that include the following:
- More efficient use of available resources to extract oil and gas
- Advances in drilling technologies, especially as they relate to hydraulic fracturing
- Increased use of MWD techniques to reduce wasted drilling time and provide in-depth information for drill operators to guide future extraction efforts
Companies that offer MWD technical support can help oil drilling operations achieve higher returns on their investments by making the drilling process more efficient. These highly advanced technological tools can provide on-the-spot feedback on drilling approaches to ensure the highest level of information for operators in the oil field.
What Is MWD?
Measurement-while-drilling equipment is designed to provide information to crews during the drilling process. These tools incorporate accelerometers, gyroscopes and magnetometers to record data on wellbore positioning and direction. This information is transmitted through electromagnetic telemetry to operators on the surface, allowing immediate adjustments to ensure the most effective extraction of available oil. MWD is especially important for shale oil drilling sites; precise positioning of equipment can make the difference between profitability and wasted effort in these operations.
Optimizing Profitability with MWD
Opting for MWD rental rather than making a large upfront investment in equipment can sometimes provide significant financial benefits for oil extraction firms:
- Renting rather than purchasing can allow companies with finite financial resources to access higher quality equipment for improved results in the field.
- As MWD technologies continue to evolve, oil drilling firms can upgrade to the latest and most advanced equipment without the inconvenience and expense of trading up. This can allow greater flexibility for companies interested in staying current with the latest developments in the MWD industry.
- MWD rentals also provide predictable monthly expenses, offering much-needed stability in the volatile field of energy production.
Providing up-to-date MWD equipment and offering expert training in the use of these tools can allow shale oil drilling operations to achieve maximum profitability with a relatively small initial investment.
Even as oil production costs continue to fall, making the most efficient use of available financial resources is critical to ensure ongoing profitability. Renting MWD equipment and investing in training for drill operators can ensure that petroleum extraction companies stay competitive and financially viable as conditions continue to evolve in the modern energy industry. instant payday loans online
Once abandoned as unprofitable, the Permian Oil Basin area of West Texas is currently undergoing a resurgence thanks to modern technologies. Hydraulic fracturing, most commonly referred to as fracking, has been used to good effect in the shale formations of the Permian. When combined with advanced horizontal drilling techniques, fracking is allowing the area to produce significant amounts of oil. Measurement while drilling (MWD) methods are further improving productivity and profitability to allow some investors to turn profits even with current low oil prices. Companies who invest in MWD training are likely to perform better over the long haul in the beleaguered energy industry.
Why Is the Permian Succeeding?
As oil prices approach historic lows due to a glut of supply on the market, many Wall Street investors have turned their back on the energy industry. The Permian Basin appears to be an exception to this rule and has attracted significant attention and financial support over the last few years. A number of factors have contributed to this situation:
- The infrastructure built in the 1970s when the Permian Basin was in full production mode is largely intact and can be used to manage current needs in this area of Texas.
- Transportation options and the proximity of oil refineries and petrochemical processing plants are also key elements in the current success of the Permian.
- Both fracking and horizontal drilling methods have proven extremely successful and productive in this area.
- Drilling companies can sometimes use existing vertical wells as the foundation for horizontal drilling, saving time and effort during the initial stages.
- Advanced MWD technical support can pinpoint the areas most likely to produce larger yields and can increase the return on initial investment for energy companies and their financial supporters.
The lessons learned in the oil industry since the 1970s have been put to good use by a number of companies now operating in the Permian Basin. The knowledge gained from previous experience has allowed these firms to achieve profitability despite the excess supply of oil currently on the market in the United States.
The Importance of MWD in Energy Production
MWD techniques allow engineers to measure and assess the effectiveness of their methods while their drilling operations are underway. This can significantly improve the ability of these energy professionals to make accurate adjustments and to increase the overall return on investment for their ongoing operations. Even with added investment funds currently flowing into the Permian Basin area, efficient production continues to be a priority to ensure the highest degree of profitability for operations in this area. MWD kits allow companies to make changes on the fly to ensure the most successful approaches to oil reserves locked in shale in these key areas of West Texas oil country.
Reducing the Initial Cost of Implementation
While many companies are investing in advanced MWD training for their employees, financial concerns may limit the ability of these firms to invest large sums in equipment to implement these techniques in the field. Companies that offer MWD rental equipment can often provide a valuable bridge toward full implementation for cash-strapped companies and can provide a number of key benefits:
- Many rental companies also offer MWD training to allow more effective use of these tools in oil drilling operations.
- Much-needed MWD technical support is usually only a phone call away.
- In some cases, companies that provide rental services also sell MWD kits, allowing oil drilling companies to enjoy added confidence when they are ready and financially able to buy.
MWD rental services offer companies the chance to try before they buy. This added financial flexibility can pay significant rewards for oil drilling operations profitability in today’s challenging economic environment.
The dramatic success of the Permian Basin may point the way for oil companies looking to make their mark on the energy industry. By revisiting areas once thought to be unsalvageable, forward-thinking business leaders may be able to achieve great things on behalf of their investors and their customers.

Everyone has gotten a lot more conscious of where the money is going since oil prices dropped. At $100 per barrel, everyone was making money. Now, only the most efficient are showing a profit. The new drilling rig models show the new emphasis on efficiency at every step in the process.
New “walking rigs” have reduced traditional relocation costs from around $100,000 to about $7000. The high tech “feet” on these new rigs allow operators to transfer or “walk” their rig to a new location without taking it apart. When you consider that a company Mike drill 30 holes in a year in a given location, the cost savings is tremendous.
This is just one example of how operators are using technology to help them survive the downturn and preserve the thousands of jobs the oil business provides. Companies are also using the latest high-tech drilling components and imaging to identify natural cracks in the wells and even refractivity previous wells to pump out the oil that was left behind.
It’s all about being efficient. MWD designs and manufactures field ready products that deliver maximum efficiency and stability. We understand the need for cost savings and help you achieve the highest productivity for the lowest cost.
Thankfully, enough smart operators are incorporating new technologies and equipment to ensure that even in these worst of times there will be plenty of drilling activity in Texas.
<img class="size-full wp-image-195 alignright" src="http://mwdkits.com/wp-content/uploads/2012/10/mwd-drilling recommended you read.jpg” alt=”mwd-drilling” width=”100″ height=”100″ />Hydraulic fracturing, also referred to as fracking, is often presented as a new technology by those unfamiliar with this extraction method. In fact, the use of water and other liquids as a fracturing mechanism was first implemented during the Civil War, more than 100 years ago. Colonel Edward A. L. Roberts discovered the principle behind fracking by using torpedoes to explode canals that blocked progress across battlefields. He patented his discovery in 1865 under the name of the “Exploding Torpedo,” and it was generally used until the 1930s to increase oil production in artesian well locations. Later advances, including measurement while drilling (MWD) techniques, have revolutionized the art and science of hydraulic fracturing. Investing in professional MWD training is essential to achieve the best and safest results during fracking operations.
The process patented by Colonel Roberts was used to increase the production of oil wells by as much as 1200 percent. The Roberts Petroleum Torpedo Company was founded to serve the needs of the oil industry and charged as much as $200 per nitroglycerine torpedo, a considerable sum in the years immediately following the Civil War. The results were impressive and spurred competition from a number of other companies that wished to share in these profits. The patents held by Colonel Roberts prevented these firms from using his process, however, and shooting wells soon became standard procedure for oil companies in the states of Kentucky, Pennsylvania, West Virginia and New York.
A Shift in Approach
In the 1930s, hydraulic fracturing was revolutionized by the introduction of acidic fluids as a replacement for the explosives previously used to stimulate production in oil and gas wells. Further experimentation resulted in the development of even more effective extraction methods. In 1949, the Halliburton Oil Well Cementing Company acquired a patent on a fracking procedure that incorporated sand, treated gasoline and water to create numerous cracks in an existing oil well. This general approach continues to be used in the oil industry to the present day:
- A proppant, usually sand, ceramics or a mix of both, is combined with treated water and injected under pressure into an oil well or shale bed.
- The high pressure of this suspension causes cracks in the rock and allows oil to be released from pockets and cavities inside the rock or shale, thus stimulating higher production from the well or field.
To achieve the best possible results from this process, it is necessary to position the drill equipment precisely. MWD kits can provide added information to drill operators to assist in pinpointing the right directional and vertical location for optimal results.
MWD in Action
By providing a steady flow of information regarding drilling conditions, MWD equipment can increase the effectiveness of fracking operations. The data provided by these systems typically includes the following:
- Real-time directional surveys to ensure accurate results
- Temperatures and vibrations downhole
- Rotational speeds for drill bits
- Torque readings
- Ongoing volumes of mud flow
This information can allow faster response times and increased accuracy throughout the drilling process. By ensuring that equipment is positioned correctly and that all aspects of the downhole operation are monitored and recorded, MWD systems can streamline the process and ensure the most effective extraction of oil from wells, fields and shale formations.
Working with a company that specializes in MWD equipment can provide added support for the workflows and processes involved in oil extraction. These firms typically provide MWD technical support to ensure that these advanced monitoring systems are operating at maximum efficiency and that operators have the MWD training needed to read and interpret the results. The hydraulic fracturing process has changed considerable since Colonel Roberts first blew up a well with a torpedo. MWD kits are one more tool in the arsenal of the modern petrochemical industry.

The world runs on oil, and oil companies are seeking new oil-rich areas to help satisfy the never-ending need daily. The Arctic has recently emerged as the newest region to be explored. Newer technologies have expanded the possibilities considerably, especially in conjunction with measurement while drilling (MWD) technology, which can be used stateside or in the Arctic. MWD training will enable drill pilots to conduct real-time measurement of conditions surrounding the drill pipe screen that will help determine accurate positioning of downhole equipment. MWD systems within the drill string sense and transmit data regarding the temperature, direction, angle and type of tool face required for the most advantageous drilling.
With increased demand for oil from China and India, it has become imperative that the Arctic and its seas need to be explored for their potentially huge oil resources. In 2009, the U.S. Geological Survey reported that the Arctic could have up to 30 percent of the world’s undiscovered natural gas reserves and nearly 15 percent of its undiscovered oil. That adds up to some 160 billion barrels of oil, which is over 70 billion more than had been previously estimated.
The Arctic has been described as one of the most promising regions for oil. In tandem with the MWD technical support available to enrich the drilling’s productivity, it seems likely that the frigid Arctic fields could yield enough oil and natural gas to supply the needs of the United States and the burgeoning Asian markets. MWD kits will aid in the drilling process by directing drill pilots toward the richest areas to seek oil.
Although most deep ocean basins do not have a high potential for gathering petroleum, the Arctic is still an area where both oil and gas are there for the taking. The majority of the reserves are estimated to be beneath less than 500 meters of water. That is only one-third of a mile deep. With a worldwide demand of 30 billion barrels per year, the potential Arctic yield is enormous, which is why the largest oil companies on earth are jostling for their slice of the pie.
The main obstacle to these vast oil reserves is the possible negative environmental impact. Since the catastrophic spill in the Gulf of Mexico, green campaigners have lobbied long and hard against oil drilling in such pristine waters as the Arctic, especially since only 20 percent of its area is accessible during the winter. Greenpeace claims that an Arctic oil spill would be difficult to stop.
Drilling would have to be carried out only during certain times of the year according to Wood Mackenzie oil analyst Nick Gellatly. He cites the rising temperatures in the area as a warning rather than an opportunity. Drilling could also release toxins like mercury, arsenic and lead into the ocean says the Natural Resources Defense Council. It is seeking ironclad rules for countries trying to obtain or allowing oil drilling within their territorial waters.
The Oil Spill Response Challenges in Arctic Waters report says that the frigid environment enhances the chance for a spill and impedes the possibility of a fast cleanup if one were to occur. The contributing factors to a delayed spill response would be the extreme cold, high winds, low visibility and a lack of natural light. However, the extenuating circumstances have not dissuaded some of the biggest oil companies in the world from pursuing the possible riches. Shell Oil recently abandoned its efforts after squandering some $7 billion in what it described as a “disappointing” effort to drill for oil in the Arctic.

To keep up with advancements in drilling technology, well logging has been forced to evolve and improve. Measurement-while-drilling, or MWD, is a natural consequence of this and represents the latest and best well logging technologies. This type of drilling is very complex, so MWD training is crucial for accurate data. Because MWD provides drill bit information, wellbore position information and directional data, it allows for greater precision, efficiency and control. With a solid understanding of MWD fundamentals, you can make a more educated choice while investing in or leasing this type of equipment.
Why is MWD Necessary?
Measurement while drilling was developed to address issues when drilling wells with angles that exceed 60 degrees. This makes it impossible for standard measurement tools to be pushed through the well in order to retrieve information, leaving engineers in the dark. Not surprisingly, this results in reduced efficiency and productivity. Instead of sending logging tools in after a drill, they have been incorporated into the design of the drill itself. As a result, they are there every step of the way, relaying crucial information to engineers and operators on the surface.
How it Works
With this type of logging while drilling, measurement and logging tools are enclosed within a single module that is located in the steering tool of the drill string, which is located at the end of the drilling apparatus. Real-time drilling information, directional data, drill bit and wellbore position information are all acquired via accelerometers, magnetometers and gyroscopes. In this way, operators and engineers are constantly apprised of the borehole inclination and azimuth while drilling occurs, allowing them to make decisions along the way. In this way, MWD helps to improve accuracy, efficiency and productivity while drilling.
The information that is gathered during the MWD process is sent as pulses through the mud column and through electromagnetic telemetry. On the surface, it is decoded immediately. It can also be transmitted to remote locations right away. With clear, concise information constantly streaming to them, engineers can more accurately position wells based on the geological features of reservoirs. In some cases, MWD kits also include video cameras, which further enhance engineers’ ability to make accurate, informed decisions singulair for allergies. At any rate, the data that is collected with various instruments provides incredible insight into the geological features and other variables of the area being drilled.
Benefits of Measurement While Drilling
MWD provides a wealth of information to engineers. For instance, it keeps them apprised of the condition of drill bits. In this way, it is possible to know when a drill bit is wearing down and potentially about to fail. The data provided by MWD also helps to determine the overall value of a reservoir and its contents, saving valuable time. For example, drilling can be abandoned more quickly if it is determined that a reservoir does not have the expected payload. On the other hand, it also confirms when a reservoir is a worthwhile option, ensuring that engineers focus their efforts in that area.
