Southern Energy Corp. has tied-in production from the GH 19-3 #2 horizontal well drilled in the Selma Chalk in Gwinville field, Mississippi.

Southern’s Generation 3 completion design increased the stage count by over 275% and the proppant concentration by over 40% as compared with the most recent Selma Chalk horizontal wells completed in Mississippi between 2013 and 2015, and initial flowback performance suggests that the increased completion intensity is having a positive result.

After about 1 week of clean-up, the well is flowing at 7.7 MMcfd (1,280 boe/d) at a restricted flowing pressure of 1,100 psig. Production from the well is flowing directly to sales.

The well continues to produce more than 2,000 b/d of load fluid, with about 24% recovered to date. Throughout the first week of production, as more load fluid is recovered, the well’s gas rate has consistently increased day-over-day.

With additional volumes from the new well, Southern’s current working interest sales production has increased about 60% to 3,175 boe/d (96% gas). The additional natural gas production from the new well is unhedged and being sold at current NYMEX gas prices.

Stimulation operations on GH 19-3 #3 and #4 wells have also been completed, and both wells will begin flowback and clean-up shortly.
