Expert Oil Lease Workover Services to Maximize Well Production

Evaluating Workover / Re-Entry / Shut-In Properties

Understanding Historical Production and Decline

When evaluating Workover, Re-Entry, or Shut-In properties, the first thing to examine is the well’s historical production data. Analyze how much oil, gas, and water the property has produced over its lifetime and note the decline trends. It’s crucial to identify if production stopped due to mechanical issues, market conditions, or reservoir depletion. Wells that were shut-in while still producing at an economical rate, or those that declined rapidly due to correctable problems, can often be good candidates for workover or re-entry projects.

Assessing Mechanical Integrity and Wellbore Conditions

Next, carefully assess the mechanical integrity of the wellbore and all surface equipment. Review completion reports, wellbore schematics, and any available downhole surveys to look for problems such as collapsed casing, stuck tubing, or corroded equipment. Wells with strong casing and minimal mechanical issues are less risky and more attractive for workover or re-entry. Any log or pressure test data should be studied to confirm wellbore integrity and to identify zones that might have been missed or bypassed in initial completions.

Evaluating Remaining Reserves and Economic Viability

Finally, evaluate the remaining hydrocarbon reserves and the project’s economic potential. Use reservoir data, past production performance, and decline curve analysis to estimate volumes that can be recovered with a workover or re-entry. Consider market pricing, operating costs, and regulatory requirements to forecast whether the investment is justified. Wells with strong upside potential and low incremental costs can provide attractive returns, but be cautious of properties requiring extensive and costly remediation with limited reserve potential.
