Following the December 1, 2017 acquisition of 12 oil wells in the southern Michigan Basin, Meridian Resources moved quickly to perform a plugback and uphole recompletion of the Gilg 1-2 well in Calhoun County, Michigan. Gilg 1-2, which targets a Silurian pinnacle reef, was originally completed in 2013 in the lowermost portion of the oil column within the Silurian Brown Niagaran reef formation. The original completion cumulatively produced approximately 60,000 barrels of oil before watering out due to a natural water drive. Meridian's recompletion of the well at the end of December 2017 involved setting a cast iron bridge plug above the original perforations, perforating a new interval at the top of the reef formation at approximately 3,100' MD/TVD, and acidizing the new completion before putting the well back on pump on January 4, 2018. Initial 30-day production for the recompletion has averaged 40 BOPD and 120 BWPD.
