Operators and drillers can now take advantage of two new perspectives on drilling that have been recently showcased as Spotlight on New Technology award winners–an all-encompassing, all-OEM managed pressure drilling (MPD) integrated solution and the OptiDrill* real-time drilling intelligence service.
Due to the new reservoir-to-flare-stack MPD offering, operators and contractors planning to conduct an MPD operation no longer need to rely on coordination of multiple entities throughout the phases of installation, commissioning, and execution. The Schlumberger integrated MPD solution includes design, engineering, manufacturing, system integration, well engineering, and onsite well delivery services from one supplier.
Operators and drillers are also benefitting from real-time expert advice available through the recently introduced OptiDrill real-time drilling intelligence service that helps mitigate risk and increase efficiency during drilling. The drilling intelligence service is offering early detection of ROP limiters and drilling hazards; drillers receive immediate guidance on how to mitigate severe downhole dynamics so that the BHA is protected and the bit run is extended.      Â
Game-changing MPD optimisation
The integrated MPD offering provides game-changing optimization of drilling and production operations. The MPD control system can be precisely scaled to customer needs or specific well demands per level of well complexity. It also features enhanced kick detection to automatically respond with the required choke control solution to reduce environmental impact. Operators can eliminate extra runs and improve well productivity as a result of reduced formation damage. The system significantly reduces NPT resulting from mud losses and potential for stuck pipe events during drilling and tripping operations. Other benefits include lower total cost of ownership and a single point of contact with 100 percent accountability for all aspects of the system throughout the MPD operation.

The integrated riser joint and all surface equipment are controlled from one platform, allowing operators the flexibility to efficiently switch from conventional drilling to MPD applications or riser gas handling operations.
Real-time expert drilling advice
While drilling, it is important to detect whirl, bounce, and stick/slip motions to preserve the life of the BHA while progression of vibration type and amplitude helps to modify drilling parameters and minimize energy lost to vibrations. Also, quantifying weight and torque transfer allows early identification of abnormal downhole conditions.
By achieving these insights, the OptiDrill real-time drilling intelligence service mitigates drilling risk through the combination of downhole automated algorithms. The algorithms enable continuous identification of hazardous drilling dynamics events and provide the operator with actionable information as well as real-time guidelines for immediate action while drilling. The service also improves drilling performance, particularly in challenging environments, by advising on actions to eliminate destructive dynamics and providing safe operating parameters based on bit-rock interaction information acquired downhole.

To aid casing running, the service also detects microdogleg and spiraling using bending moment data, enabling evaluation of borehole stability over time. Remote interpretations are shared with the rigsite team to help identify optimal surface parameters. Automated quick event detection algorithms monitor for indications of plugged bit nozzles and drillstring washout.
