Well Casing Baseline Analysis for the Big Hill Strategic Petroleum Reserve Site
- Sandia National Lab. (SNL-NM), Albuquerque, NM (United States). Geotechnology & Engineering Dept.
This report analyzes data from multi-arm caliper (MAC) surveys taken at the Big Hill SPR site to determine the most likely casing weights within each well. Radial arm data from MAC surveys were used to calculate the approximate wall thickness of each well. Results from this study indicate that (1) most wells at the site have thinner wall thicknesses than expected, (2) most wells experienced an acute increase in diameter near the salt/caprock interface, and (3) there were isolated instances of well sections being the wrong casing weight. All three findings could have a negative impact on well integrity.
