Directional Drilling Optimization - Extended Reach Drilling | SLB

Directional drilling services

Reach and stay in the productive zone faster and more efficiently

Illustration showing the DJ Basin, just one directional drilling innovation boosted ROP while drilling each of 12 wells in single runs—vertical through the curve and into the lateral.

Schlumberger provides the expert directional drilling services needed for high-quality wellbores that stay in the “sweet spot”—your optimal production zone. Our proven trajectory control technologies provide precise directional control using our LWD and MWD services that deliver high-quality data, enabling time-critical decisions, for accurate drilling of extended-reach horizontal and complex directional wells.

Our technologies

We have unmatched capabilities that integrate well construction digitization and technologies such as at-bit steerable systems and definitive dynamic surveying; we invented the rotary steerable system, and we now lead the industry with groundbreaking autonomous directional drilling. Additionally, we closely collaborate with directional drillers and directional-drilling contractors using real-time analysis solutions to monitor downhole conditions, manage BHA dynamics, improve casing-point selection, and reduce drilling risks—all enhancing drilling optimization.

Autonomous Directional Drilling

Autonomous directional drilling unites all the technology, backed by all the engineering and domain expertise that Schlumberger has amassed for a century.

At-Bit Steerable Systems

Integrated steering and cutting structure technology for unprecedented DLS capability, durability, and ROP.

Rotary Steerable Systems

RSS offerings for maximum directional control.

PowerDrive rotary steerable systems

PowerDrive RSSs take on every drilling application, from conventional to ultraHT and verticals to ultraERD. Full rotational capability, onboard power generation, measurements close to the bit, and nine different service options provide fast and robust tools to power up positive well outcomes, so you hit your target, drill cost effectively, and reduce NPT.

With the most experience on the market, the PowerDrive RSS family has drilled over 320 million feet.

Minimize the expense of each barrel produced

Full rotation means PowerDrive RSSs drill faster and pull out of hole faster, reducing time to production. They are engineered for rugged endurance in harsh applications and combine reliable measurements and fast downlink configurations with nimble steering options. That means the PowerDrive RSS family delivers well placement so precise that drillers can thread the needle, even in those narrow sweet spots. The result is an easy-to-complete wellbore that minimizes construction time and expense within the pay zone.

Drilling Motors

Motors that enhance torque output and directional control.

We offer a large variety of fit-for-purpose positive displacement motors for high-volume and high-tier applications. These motors not only provide improved reliability for extended run intervals, they may also be paired with DynaForce DTX thin-wall motor power sections and DynaPower motors elastomers to deliver performance in the harshest drilling environments.

Additionally, combining our high-performance drilling motors with the ability to model application- or basin-specific motors means we can provide unique solutions to satisfy any customer need.
