Rotary Steerable MWD for Faster, More Accurate Wells

Introduction

Modern horizontal wells demand two things that were once considered tradeoffs: speed and precision. Drilling faster without staying in zone sacrifices reservoir contact. Drilling accurately without efficiency inflates well cost. The solution is not choosing one over the other. It is integrating Rotary Steerable Systems, commonly referred to as RSS, with high performance Measure While Drilling technology.

At ProDirectional, RSS and MWD are deployed as a single drilling system. This approach allows operators to drill long laterals, complex curves, and tight landing windows while maintaining high rotary time and wellbore quality. Across basins like the Permian Basin, Haynesville Shale, and Eagle Ford Shale, this combination has become the standard for high performance directional drilling.

What a Rotary Steerable System Actually Does

A Rotary Steerable System allows continuous rotation of the drillstring while steering the wellbore. Unlike conventional sliding motors, RSS tools maintain constant rotation, which reduces friction, improves hole cleaning, and produces smoother wellbores.

RSS systems use internal steering mechanisms to change the trajectory of the well without stopping rotation. This provides a significant advantage in long laterals and high dogleg environments where sliding becomes inefficient and unstable.

However, RSS tools do not make decisions on their own. They rely on real-time downhole measurements to know where to steer. That is where MWD technology becomes essential.

Why MWD Is the Control Layer of RSS

An RSS tool is only as effective as the data guiding it. Measure While Drilling systems provide the real-time information that tells the RSS how to steer.

MWD systems supply:

• Inclination and azimuth
• Azimuthal gamma for formation mapping
• Toolface and orientation
• Pressure and vibration
• Survey quality and depth correlation

This data allows the RSS to continuously adjust steering as formations change. In complex reservoirs, small trajectory errors can quickly move the well out of zone. High quality MWD data prevents that from happening.

ProDirectional’s MWD systems are designed to deliver stable telemetry and accurate measurements even in high temperature, high vibration, and extended lateral environments.

How RSS and MWD Improve Drilling Speed

One of the biggest drivers of drilling efficiency is rotary time. Sliding slows drilling, increases wear, and introduces wellbore tortuosity. RSS systems guided by reliable MWD data allow drilling teams to remain in rotary mode for most of the well.

Higher rotary percentages lead to:

• Higher rates of penetration
• Less vibration
• Reduced motor wear
• Improved hole quality
• Lower torque and drag

Across long laterals in the Permian Basin and Eagle Ford Shale, this difference can translate into days of saved drilling time and millions of dollars in reduced cost.

Wellbore Quality and Completion Performance

Speed alone does not define success. The quality of the wellbore has a direct impact on casing runs, cement jobs, and completions.

Smoother wellbores created by RSS and guided by high resolution MWD data result in:

• Easier casing runs
• Lower risk of stuck pipe
• Better cement coverage
• Reduced friction during fracturing
• Improved production efficiency

In formations like the Haynesville Shale, where laterals are long and pressures are high, wellbore quality is critical to safe and successful completions.

Geosteering and Reservoir Placement

Azimuthal gamma tools integrated into MWD systems allow directional drillers to see formation boundaries around the wellbore. This enables precise geosteering, even in thin or structurally complex reservoirs.

When combined with RSS, this information allows continuous steering to stay within the target zone. Instead of reacting after the well has drifted, the RSS can make small corrections in real time, keeping the well exactly where it needs to be.

This capability is especially important in stacked plays and tight reservoirs where vertical and lateral accuracy directly affects production.

Real Field Performance

ProDirectional has demonstrated the value of RSS and MWD working together in multiple basins. In one Permian Basin project, a three mile lateral was drilled in just 156 hours using a rotary steerable system guided by high resolution MWD data. This level of performance requires stable telemetry, accurate surveys, and precise steering response.

In other wells, ProDirectional has navigated significant true vertical depth changes mid lateral while maintaining formation position, completing both the curve and the lateral in a single run. These results are only possible when RSS and MWD operate as an integrated system.

Reliability Matters as Much as Precision

Long laterals and complex well profiles place enormous stress on both RSS and MWD tools. Reliability becomes just as important as accuracy.

High performance MWD systems must deliver:

• Stable telemetry over hundreds of circulating hours
• Sensor accuracy under vibration and shock
• Electronics that withstand high temperature
• Mechanical durability through long footage

ProDirectional’s MWD systems have supported extended runs exceeding 200 circulating hours while drilling thousands of feet without interruption. This reliability reduces trips, lowers operational risk, and keeps drilling programs on schedule.

Why Integrated RSS and MWD Systems Reduce Risk

When RSS and MWD systems operate together, drilling teams gain full control of the wellbore. Real-time measurement allows immediate steering adjustments, pressure data supports safer drilling, and azimuthal gamma keeps the well in zone.

This reduces:

• Sidetracks
• Unplanned trips
• Lost in hole incidents
• Completion issues
• Production variability

For operators managing large drilling programs across basins like the Permian, Haynesville, and Eagle Ford, this consistency is just as valuable as speed.

The Future of Directional Drilling

The future of high performance drilling lies in deeper integration between measurement and steering. RSS tools will continue to evolve, but they will always depend on accurate, reliable MWD data to guide their actions.

ProDirectional continues to invest in both technologies to deliver drilling systems that provide speed, precision, and reliability across the most demanding oil and gas wells.

High Performance MWD Systems for Modern Directional Drilling

Introduction

Measure While Drilling, commonly known as MWD, is the backbone of modern directional drilling. Without reliable MWD systems, operators lose visibility into the wellbore, struggle to stay on plan, and face higher drilling risk.

In today’s oil and gas wells, MWD technology does far more than transmit inclination and azimuth. It delivers formation data, pressure information, and downhole diagnostics that allow drilling teams to place wells accurately, maintain high rates of penetration, and avoid costly surprises.

At ProDirectional, Measure While Drilling (MWD) systems are engineered and deployed as part of a fully integrated directional drilling platform. Every tool, sensor, and telemetry package is selected and supported based on real field performance across the Permian Basin, Haynesville, and other major oil and gas plays.

What Defines a High Performance MWD System

Not all MWD equipment is created equal. A high performance MWD system must deliver three things at the same time:

• Accurate and repeatable measurements
• Reliable telemetry under harsh conditions
• Mechanical and electronic durability over long runs

Modern wells are deeper, hotter, and more complex than ever before. High doglegs, long laterals, and aggressive drilling parameters place enormous stress on MWD tools. Systems that cannot maintain data quality under these conditions quickly become liabilities.

ProDirectional’s MWD technology is built specifically for these realities.

Telemetry That Keeps Directional Drilling on Track

Telemetry is how downhole data reaches the surface. If telemetry is unstable or noisy, directional decisions become slower and less accurate.

ProDirectional’s Octane and OctaneXT MWD systems are designed to deliver consistent, high-quality telemetry in:

• High temperature wells
• High vibration environments
• Long horizontal laterals
• Extended circulating hours

These systems provide real-time inclination, azimuth, and sensor data that allow directional drillers to maintain trajectory and react quickly to formation changes.

Azimuthal Gamma for Geosteering Accuracy

Staying in zone is one of the most important factors in well economics. Basic gamma tools only show vertical information, but modern wells require a full three-dimensional view of the formation.

ProDirectional’s GeoSight360 azimuthal gamma system provides directional drillers with:

• Full 360 degree formation mapping
• Bed boundary detection
• Fault and dip identification
• Improved landing accuracy

This allows drilling teams to make precise steering decisions that maximize reservoir contact and reduce unnecessary corrections.

Pressure While Drilling for Well Control and Optimization

Pressure While Drilling, or PWD, has become a critical component of modern MWD systems. Real-time downhole pressure data allows drilling teams to:

• Detect kicks earlier
• Identify losses
• Monitor equivalent circulating density
• Optimize mud weight
• Reduce well control risk

ProDirectional integrates PWD directly into its MWD platform so that pressure data is always available to both drilling and directional teams.

Electromagnetic MWD for Challenging Drilling Environments

Not every well can be drilled with mud pulse telemetry. In shallow, air, or underbalanced wells, electromagnetic MWD systems provide a reliable alternative.

ProDirectional’s EM MWD technology allows operators to continue receiving downhole data when traditional telemetry is limited, keeping drilling programs on schedule even in difficult conditions.

Reliability Is the True Measure of MWD Performance

High performance MWD systems are measured by how long they stay in the hole and how consistently they deliver data.

ProDirectional MWD tools have supported runs that exceed 200 circulating hours and drill tens of thousands of feet without interruption. This reliability reduces trips, lowers operational risk, and improves overall drilling efficiency.

Every ProDirectional MWD system is tested, maintained, and supported by in-house engineering teams who understand how these tools perform in real drilling environments.

Field Experience That Builds Better MWD Technology

MWD systems are refined in the field, not just in the shop. ProDirectional continuously gathers data from live wells across multiple basins and uses that information to improve tool design, telemetry stability, and mechanical durability.

This feedback loop between drilling crews and engineering ensures that every new MWD system is stronger, more reliable, and better suited to modern directional drilling.

How ProDirectional’s MWD Systems Deliver Top-25% Well Performance in the Permian

Introduction

In today’s Permian Basin, drilling faster is no longer enough. Operators are judged on consistency, wellbore quality, and their ability to repeat performance across dozens of wells. That is where Measure While Drilling, better known as MWD, separates top-tier drilling programs from the rest of the field.

At ProDirectional, our MWD systems are not just data tools. They are performance engines. In 2025 alone, our teams delivered results that placed nearly half of our wells inside the top 25 percent of a major Permian operator’s entire drilling portfolio. That is not a marketing claim. It is operational reality backed by thousands of drilled feet, long run times, and repeatable execution across multiple rigs.

This level of performance is only possible when MWD technology, directional drilling expertise, and engineering discipline work together as a single system.

Field Experience Behind ProDirectional’s MWD Systems

ProDirectional’s MWD technology is not developed in isolation. It is refined through continuous field deployment across the Permian Basin, Haynesville, and other major North American plays. Every system in our fleet is tested under real drilling conditions before it is ever offered to an operator.

Our directional drilling and MWD teams work side by side in the field, using live downhole data to adjust well paths, manage vibration, and protect tool health in real time. That feedback loop between field execution and engineering is what allows ProDirectional to consistently deliver top-quartile results across hundreds of wells.

What Measure While Drilling Really Controls

MWD technology does far more than provide inclination and azimuth. A modern MWD system governs how efficiently a well is drilled, how accurately it is placed in the reservoir, and how stable the bottom hole assembly behaves under load.

High-quality MWD systems deliver:

• Real-time inclination and azimuth for precise wellbore placement
• Gamma and formation data for landing and staying in zone
• Pressure While Drilling for early kick and loss detection
• Vibration and tool health monitoring
• Survey accuracy that reduces costly corrections

When these measurements are reliable and continuous, directional drillers can keep wells on plan, minimize sliding, and maintain higher rotary percentages. That directly translates into faster drilling and smoother wellbores.

ProDirectional’s MWD technology stack is designed to deliver exactly that level of control.

Top-25% Performance at Scale

During 2025, ProDirectional drilled 74 wells for a major Permian operator. Of those, approximately half ranked inside the top 25 percent of all wells drilled company-wide for that operator. Another 32 percent ranked inside the top 10 percent.

That means the majority of wells drilled using ProDirectional MWD systems outperformed hundreds of other wells drilled across multiple service providers, rigs, and field teams.

This is not the result of one lucky run. It reflects consistent wellbore quality, reduced non-productive time, and superior curve and lateral execution driven by accurate, stable MWD data.

How ProDirectional’s MWD Systems Enable Repeatable Results

High-performance MWD services require more than just a tool in the hole. They require an integrated system built around reliability, signal quality, and engineering support.

ProDirectional delivers this through a complete MWD technology portfolio that includes:

• Octane and OctaneXT MWD systems for high-temperature, high-shock environments
• GeoSight360 azimuthal gamma for precise geosteering
• Electromagnetic MWD for drilling where pulse telemetry is limited
• Pressure While Drilling for real-time downhole pressure monitoring

These tools are supported by in-house engineering, strict QA processes, and field crews trained to maintain signal integrity under demanding conditions.

Long Runs, Fewer Trips, Better Wells

One of the most powerful indicators of MWD system quality is run length. Long runs mean fewer trips, lower risk, and more consistent wellbores.

ProDirectional recently completed an ADAPT MWD run that exceeded 250 circulating hours while drilling more than 9,700 feet on a single tool. That kind of performance requires:

• Stable electronics under high temperature
• Robust telemetry
• Reliable power management
• Mechanical integrity under vibration

These long-run capabilities allow operators to drill further, faster, and with fewer interruptions, which directly improves AFE performance.

Precision in Complex Well Paths

In a recent Midland Basin project, ProDirectional navigated a 200 foot true vertical depth change from mid-lateral to total depth while maintaining precise wellbore placement.

Using ProPower motor technology and high-resolution MWD data, the team completed both the curve and the lateral in a single run. Even with complex geology and changing formation behavior, the MWD system delivered the data required to keep the well on target.

This kind of precision is only possible when the MWD tools, motors, and directional drilling team operate as a single, integrated system.

MWD Performance in Real Numbers

ProDirectional MWD systems have supported runs that include:

• Over 14,800 feet drilled in a single run
• Temperature exposure from 226°F to 351°F
• 200+ circulating hours
• Three-mile laterals drilled in 156 hours using RSS
• More than 32,000 feet drilled in 10 days of AFE

These are not lab conditions. These are real wells drilled in the Permian Basin using ProDirectional MWD equipment and field crews.

Why Operators Choose ProDirectional MWD Services

MWD services are not just about sending data to surface. They are about delivering wells that stay on plan, finish faster, and cost less.

ProDirectional’s MWD services give operators:

• Better landing accuracy
• Higher rotary percentages
• Lower tortuosity
• Reduced slide time
• Improved lateral ROP
• Fewer unplanned trips

This is why operators continue to trust ProDirectional to deliver critical wells under tight economic and technical constraints.

Building a System, Not Just Renting Tools

MWD rentals alone do not create top-quartile performance. The difference comes from engineering, calibration, maintenance, and real-time support.

ProDirectional treats every MWD system as part of a controlled, engineered fleet. From shop to rig, every tool is tracked, tested, and supported by in-house specialists who understand how it will be used in the field.

That discipline is why ProDirectional MWD systems continue to deliver long runs, clean data, and consistent results.

The Foundation of Directional Drilling Excellence

Directional drilling performance starts with the data. Without reliable Measure While Drilling systems, even the best directional drillers are flying blind.

ProDirectional’s MWD technology gives field teams the visibility they need to place wells accurately, drill them efficiently, and deliver repeatable results across entire drilling programs.

That is how ProDirectional continues to place wells inside the top 25 percent of operator performance year after year.
