Workover Candidate Selection

Use Cases  /  Workover Candidate Selection

Situation

100,000+ Wells

There are thousands of mature oil and gas fields in the US with 100,000s of wells to monitor and optimize with an ever-shrinking skilled workforce. That means hundreds of wells for each production engineer to analyze daily. This routine work normally is not automated and leads to lengthy well-by-well reviews.

Challenge

Missed Production Targets and Increased Costs

Regularly the best workover candidates with the highest potential production gain have been overlooked because they are not always obvious at first sight. Suboptimal workover investments lead to missed production targets and increased lifting costs.

PetroVisor Solution

Automated Screening

The entire candidate screening model has been automated i.e. continuous automated screening for underperforming wells, including KPI calculations, data analytics, problem detection, cost and risk estimation, NPV calculation and ranking of workover opportunities. A knowledge base for improving decision making is built.

Added Value Gained

More Promising Workover Candidates and Standardized Work

Additional workover opportunities were identified that had gone unnoticed previously. As a result, the operator’s capital program started to deliver more production at a lower cost-per-barrel. Quickest return and lower workover costs per barrel. Technical and reservoir risk is lowered. Premature well abandonment is avoided (= extending well life and deferring well plugging costs). Engineering time is saved by highlighting the best opportunities, engineering time is spent on the most promising workover candidates, and work is standardized on best practices.
