Cement Plug with CemNET Technology Enables Sidetrack After Lost Circulation Event, Pakistan

To deliver lightweight cement with high compressive strength and avoid losses, Schlumberger designed and delivered a 2.4-m3 [15-bbl] cement plug comprising LiteCRETE slurry at 1.44 g/cm3 [12 lbm/galUS] and CemNET technology at 4.3 kg/m3 [1.5 lbm/bbl]. No losses were seen after the plug hit the perforations, and the well had full returns during reverse circulation. After setting, the plug was tagged with 5-t weight on bit and the well pressure tested to 6.9 MPa [1,000 psi].
