Case Study: a large operating company reduces drilling fluid losses with SLB SCREEN PULSE and DURAFLO screens

Costly Drilling Fluid Losses to Shakers Reduced by 26% in the Duvernay Shale

SLB worked with a large operating company drilling in the Duvernay Shale, where the customer wanted to reduce drilling fluid lost to drill cuttings and lower the volume of drilling waste while maintaining high-quality mud for the wells. The challenge was especially important because of the high rate of penetration and long well lengths, which increased low-gravity solids contamination at the shakers.

SLB deployed SCREEN PULSE fluid and cuttings separators on MONGOOSE PRO dynamic dual-motion shale shakers with DURAFLO composite replacement screens. Over an 8-day trial, SLB helped the customer recover an average of 20 bbl/d (3.2 m3/d) of drilling fluid, save CAD 22,000, reduce average mud on cuttings by 26%, cut waste by 76,150 lbm (34,541 kg), and improve HSE and operational efficiency without increasing low-gravity solids.
