DrilTech's average Senior MWD Operator has 20 years of MWD experience and represents 65% of our field staff.
Our Operational management staff averages over 9 years of managing field operations.








Our Measurement While Drilling (MWD) System consists of the most accurate and reliable instruments available and are packaged in our proprietary probe-based housings.

Unique valve configurations, coupled with our pilot-actuated mud pulse system, provides reliable pulse decoding at extreme depths and with high levels of fibrous lost circulation materials (LCMs) frequently used in today’s market.

Versatility and reliability are key features of our MWD system packaging. These systems allow complete retrievability and reinsert ability while allowing for capturing and active dampening on all axes to maximize reliability in the harshest drilling environments.

Measurement while drilling reliability


All directional sensor packages are rated to 175⁰ C (347⁰ F) and are designed and packaged to withstand 1000 G 0.5 mSec shock severity. Extremely stable gravity toolface (Gfta) measurements accommodate accurate inclinations as low as 2 degrees.


Our team of experienced managers, technicians, and field operators are committed to providing the highest level of support and service, every day of the year. We offer an open line of communication to our customers who can count on us 24 hours a day, 7 days a week.

Real-Time Data

“All transmitted MWD Data is available Real-Time to your EDR system via our WITS M/L compliant equipment. Local and remote access allows users to

easily retrieve accurate data in a system that is easy to use and manage. The system is also setup to perform database recoveries, import/export and email data.

MWD Accuracy

DrilTech’s equipment and methods allow us to obtain survey data while drilling ahead immediately after a connection is made and pumps are cycled on. As soon as pumps are on we can tag bottom and drill ahead while the survey data is being decoded under most applications.

This technique effectively reduces off bottom time to actual time needed to make the next connection under most circumstances. This method can potentially reduce total time waiting on surveys by 10-20 hours for a typical lateral well.

Measurement while drilling

Dynamic Sequencing

Dynamic sequencing enables faster drilling by switching from providing tool faces while sliding to more gamma, continuous inclination, and shock and vibe data while rotating.

It also allows us to take surveys in lost circulation zones by using rotary detection methods.


Downlinking allows us to maximize bits/sec transmitted with the flexibility to adjust in the event noise from pumps, agitator, pump, or other drilling noise makes decoding more difficult. All this can be done in a couple of minutes, without the need to pull out of the hole to reprogram the tool
