In Washington, an operator launched a modernization and safety project for a hydroelectric dam that required drilling and casing more than 200 boreholes into bedrock for grout and cement slurry injection to reduce water seepage. After grouting, dual-string casings—140 mm steel and 112 mm PVC—needed to be cut and removed at the lakebed to eliminate … Read more

During a Deepwater Gulf of America (GoA) campaign, Wellbore Integrity Solutions (WIS) successfully milled a single‑trip window in uncemented 14‑in., 115‑ppf Q-125 heavy‑wall casing (0.82‑in. wall thickness). The operation enabled smooth directional BHA pass‑through and uninterrupted continuation of drilling operations. This application required precise window placement and consistent milling performance in heavy‑wall casing.

During a large-scale platform-based P&A campaign, the operator required the efficient cutting and recovery of triple casing string, in a single operation. The scope included cutting through the 13⅜” intermediate casing, 20” casing, and 30” conductor, with all three strings cemented together exhibiting significant eccentricity. Multi-string cutting in platform environments presents inherent challenges, including harsh … Read more

Data-driven advancements in multi-string cutting, eliminates pre-milling and significantly reduces rig time for a major North Sea P&A campaign Wellbore Integrity Solutions (WIS) delivered a disciplined, data driven enhancement program that transformed our multi-string conductor cutting methodology—reducing rig time, improving cut quality, and increasing operational efficiency. During a large-scale, platform-based plug and abandonment (P&A) campaign, … Read more

Reducing operational time during plug and abandonment (P&A) activities directly translates to cost savings by minimizing rig time and supporting a more sustainable abandonment strategy. In a recent offshore P&A campaign in the UAE, the operator required an efficient cut and pull (C&P) solution to recover 13⅜-inch casing. A critical requirement was verifying the integrity … Read more

Careful planning and detailed risk analysis led to the successful retrieval of a Seal Bore QuantumPacker along with a 159-ft gravel pack completion in a single run at a remote location Precise torque and drag simulations were essential to delivering this exceptional operation, which was awarded to Wellbore Integrity Solutions (WIS) for its proven expertise … Read more
