CLEAR Hole Cleaning and Wellbore Risk Reduction Service

Real-time monitoring of hole cleaning effectiveness and wellbore stability

The CLEAR hole cleaning and wellbore risk reduction service, delivered by Geoservices, a Schlumberger company, monitors hole cleaning effectiveness and wellbore stability. The CLEAR service is simple, reliable, and robust, providing real-time data to help the drilling team continually improve drilling performance and reduce NPT.

Efficient assessment of cuttings recovery

The weight of cuttings reaching the surface is continuously measured and analyzed as the cuttings come off the shale shakers. By comparing measured and theoretical volumes, the service provides early detection of inadequate hole cleaning and of excess returns caused by wellbore instability (caving) or formation damage.

Enhanced remote operations with data dashboard

Real-time cuttings flow information is obtained by a cuttings flowmeter that is located at the end of each shale shaker, which accumulates cuttings as they fall off the shaker screen. The cuttings are weighed via strain gauges then discharged, and the cycle repeats.

Results are visually displayed via the CLEAR service dashboard, accessible online whenever and wherever they are needed—at the rigsite or at remote offices for analysis by well construction engineers. The dashboard's accessibility and ease of use allow the drilling team to more efficiently assess hole cleaning effectiveness and to minimize wellbore instability risks.

Improved drilling safety and speed

Early detection enables early remediation, minimizes off-bottom circulation time, and improves safety. The CLEAR service helps prevent stuck-pipe incidents caused by packoff, lowers NPT, and maximizes ROP. It is particularly valuable in extended-reach drilling, highly deviated wells, difficult hole-cleaning conditions, unstable wellbores, and complex deepwater wells.
