|Characterize the Source of SCVF/GM to Identify Leakage Pathways, Establish an Appropriate Threshold Concentration for Well Repair, and Identify Long-term Monitoring Solutions.
- Improve source identification methodology, as characterizing the source of SCVF/GM remains challenging.
- Establish better gas sampling methods and standards, as samples become unstable over time. Gas source characterization is interpretational and unreliable.
- Analyze impacts from both SCVF/GM and repair operations to determine an appropriate SCVF/GM threshold.
- Identify a cost-effective long-term monitoring solution.
|Research Well Integrity to Establish a Permanent Barrier Criteria.
- Investigate bridge plugs and alternatives. Assess cost, longevity, and failure probability.
- Gain a better understanding of the seal integrity between the well casing and cement.
|Determine a Criteria for Cement and Cement Alternatives for SCVF/GM Repair.
- Create a tool that can assess the bond quality behind pipe, for both cement and cement alternatives.
- Reduce wellbore leakage during drilling though increased knowledge and improving cementing practices.
