FlexFusion® Technology Package

The H&P FlexRig^® fleet pushes performance and geometric limits.

Our FlexRig fleet is the heart of our drilling operations. Seamlessly integrating with our automated technologies, these super-spec rigs have served as the industry leader for decades and are designed for optimal flexibility, performance and efficiency.

FlexApp parameters can be pre-loaded to eliminate human variability

FlexApp parameters can be configured to automatically execute preplanned procedures for bit engagement/disengagement, slide set-up and stall recovery.

Advanced controller technology that enables smooth drilling using differential pressure

Autodriller Pro is an advanced control feature that enhances drilling performance. It reduces bit bounce with improved stability, resulting in more consistent engagement with the formation. This leads to improved rotating on bottom rate of penetration (ROP).

AutoDriller Pro has superior robustness and stability for regulating weight on bit, differential pressure, and torque across various drilling applications. It enhances reliability and improves ROP.

Seamlessly execute automated sequences and processes

The secret sauce to FlexFusion^® lies in its automated sequences that seamlessly execute processes to apply and remove WOB while integrating different technologies to drill a stand. It’s main goal is to effectively manage weight on bit application and removal to minimize bit whirl.

By improving consistency and process efficiency, it enables operations to drill challenging wells and reduce oil and gas lifting costs. FlexFusion^® does this by effectively managing bit whirl and ensuring consistent bit engagement and disengagement.

Efficient bit engagement reduces lateral vibrations that are associated with bit whirl.

FlexB2D® technology helps to mitigate this risk by quickly engaging the bit with sufficient depth of cut while rotating or sliding and is fully customizable.

Our suite of automated processes for applying and removing WOB effectively manage mud pumps, top drive and drawworks sequence instructions through each process. Analysis of FlexB2D 2.0 technology results will enable setpoint optimization.

Improve rotating on bottom ROP and reduce effects of stick-slip

When using active control to reduce the effects of stick-slip, the top drive interprets surface torque fluctuations as stick-slip and modulates surface RPM to prevent torsional vibrations from reflecting back down the drillstring. Our active control system helps ensure the release of trapped torque when hoisting off the bottom, preventing overactivity in stick-slip mitigation control.

FlexFusion^® releases trapped torque in the drillstring to safely orchestrate the removal of WOB when FlexTorque® technology is in use.

Detect & recover from downhole stalls

The vast majority of wells drilled include a positive displacement motor (PDM), either as the primary directional tool or as an RSS performance improvement.

PDM’s are susceptible to stalling when the torque requirements for the application exceed to capabilities of the motor. The dynamic between torque requirements and PDM capabilities can be managed through StallAssist® software to mitigate motors stalls, thereby extending motor life and preventing unplanned trips.

While recovering from the stall, the bit is safely disengaged from bottom and control is returned to the driller to initiate the process of engaging the bit.

Well-executed bit disengagement is an important process to manage bit whirl.

Efficiently disengaging the bit during instances of low depth of cut, helps mitigate the impact of bit whirl – extending the lifespan of the Bit/BHA, while reducing the likelihood of unplanned trips.

All FlexFusion^® processes that involve removing WOB, include the sequences to release trapped torque.
