With so many MWD equipment platforms available, it’s quite difficult for newcomers to find the best technology platform for their needs. Often we’re asked by clients if there is a single MWD platform that fits all use-cases. The answer is YES (with a catch!)  You can use a multi-purpose MWD equipment technology platform on just about any kind of well within a defined geographic area or basin…there’s always a catch right? Simply put, having the right technology can make a huge difference in your drilling performance and a huge difference in how happy your client is and ultimately, that’s what the directional drilling game is all about.

Our focus with this article is to highlight the best and most popular MWD/LWD platforms on the market today (in no particular order!) We will look at niche-specific Measurement While Drilling Technology as well as top multi-purpose MWD systems in this list. (Keep in mind that we are not ranking these systems.)

Depending on your use case, you can get a good idea of an mwd tool system suppliers that best suit your needs. There are plenty of mwd tools for sale on both the new and the surplus marketplace so let’s get started!

  1. Weatherford

 

Weatherford MWD

Weatherford is easily recognizable as one of the leaders in the Oil & Gas Services sector and they are no stranger to the Directional Drilling space. They have five distinct offerings to choose from.

  • Standalone tools—drift measurement tool (DMT), azimuth measurement system (AMS) and standalone azimuth measurement system (SAM)—reduce survey time and expense while enabling operators to continually monitor the wellbore remotely.
  • HEL™ hostile-environment-logging MWD system is the industry’s most robust hostile environment positive mud-pulse telemetry system, with 356°F (180°C) temperature and 30,000-psi (207-MPa) pressure ratings.
  • HyperPulse™ positive mud-pulse telemetry systems provide directional surveying, formation gamma ray and temperature measurements in all routine drilling environments and in heavy-mud and highlost-circulation-material (LCM) conditions.
  • EMpulse™ electromagnetic telemetry systems perform in mud-pulse environments and in borehole environments where mud-pulse systems cannot perform. When fully integrated with their Weatherford® LWD (logging-while-drilling) and Revolution® rotary-steerable systems, the EMpulse MWD system helps pinpoint well placement in complex wellbores.
  • TwinWells™ active-magnetic ranging systems ensure accurate placement of steam-assisted gravity-drainage (SAGD) well pairs in heavy-oil environments.

2. Halliburton

Halliburton Quasar-Trio MLWD

Halliburton’s Sperry Drilling has coined their offering the QuickPulse™ Automated Directional Gamma Service. The website says that the their mwd tool delivers quick and reliable downhole information which helps the client make sound decisions and drill longer laterals quicker. They also say that Its small-footprint design allows for up to 70 percent faster rig-up time and reduces well time and health, safety, and environmental (HSE) exposure.

Beyond their regular positive pulse mwd system, Halliburton’s Quasar Trio® measurement-while-drilling/logging-while-drilling M/LWD triple-combo service, gives exceptional insight into previously inaccessible reserves located in the harshest drilling environments. Their system is outfitted with three rugged sensors to capture resistivity, azimuthal density, and neutron porosity measurements in real-time, which helps enhance reservoir understanding.

Their website boasts that they surpass the capabilities of conventional LWD systems with the Quasar Trio service delivering accurate data in extreme high-temperature 200°C (392°F) and high-pressure to 172MPa (25,000 psi) reservoirs, helping to maximize asset value.

3. Nabors

Nabors Drilling Accusteer MWD

Nabors has thrown their hat into the ring with a collar-based system designed for the unconventional market, called AccuSteer® MWD which provides all the latest and greatest key measurements such as:

  • Continuous inclination
  • Shock and vibration
  • Azimuthal gamma
  • Downhole pressure
  • Resistivity
  • Drilling dynamics

All of which help to optimize drilling and help stay “in zone” for enhanced wellbore placement.

Their marketing material also boasts that their tools are delivered fully assembled for increased reliability and faster utilization (as it should be in my opinion. High tech tools being built in the sand, dust snow, wind, rain, etc are destined to fail.)

Here is an unexpected bonus, due to its unique design, the AccuSteer® Suite offers its resistivity logging service without adding additional BHA components or moving other sensors excessive distances from the bit. That is pretty cool.

4. Baker Hughes

Baker Hughes Navitrak MWD

For years the NaviTrak™ MWD service from Baker Hughes has provided an extremely reliable solution to accurately drill wells while minimizing non-productive time (NPT) and drilling costs.

NaviTrak MWD service is a probe-based technology that provides both directional and drilling dynamics measurements in applications ranging from conventional directional drilling and horizontal drilling to short-radius, slimhole re-entry and underbalanced drilling.

As with most others, NaviTrak™ MWD provides continuous inclination and azimuth measurements along with drilling dynamics measurements give you an understanding of the magnitude and type of vibrations encountered by the probe during drilling.

You can also acquire real-time and memory gamma-ray measurements with the NaviTrak MWD service’s optional gamma module.
