The 2 first Saltel patches (Total Sealing, 0.11in [3 mm], 19.68 and 26.24ft [6 and 8m] long, have been deployed successfully in two Coal Seam Gas (CSG) wells, in Australia.
The objective was to cover the cement squeeze area with a casing patch in each well, to restore integrity in the 7in production casing. The patches were installed after the cement remediation jobs (Perf. & Cement Squeeze).
The setting went as per job program, and post-setting pressure tests confirmed the new barriers efficiency (1,000 psi [68.94 bar], less than 2% pressure loss over 10min).
The wells are now being completed and put in production.
The local team involvement helped us a lot entering a particularly competitive new market.
The client has several hundred wells with similar issues. Our technological differentiation should help securing regular activity over there.
