SDX Energy Inc., London, will connect its SD-3X appraisal well to infrastructure at South Disouq, Egypt, following a successful production test (OGJ Online, May 22, 2018).
The SDX-operated well flowed at a maximum rate of 16.1 MMscfd of conventional natural gas during an 8-hr clean up period and was then shut in for 8 hr, during which time no pressure decline was observed. By varying choke sizes, the well was flowed for two successive 6-hr periods at average rates of 5.3 MMscfd and 8.4 MMscfd, respectively, and one extended flow period of 12 hr at an average rate of 10.5 MMscfd.
The well was shut in for a pressure build-up of 96 hr, which is currently ongoing. At completion, the downhole pressure gauges will be retrieved and the well suspended prior to being connected to local production facilities. During testing a total of 12.02 MMscf of conventional gas was produced.
“The well is located the furthest down dip on the structure and had the least amount of pay when compared to the two offset wells. We therefore limited both the test duration and peak rates to ensure that no damage was done to the well whilst testing it. The well performed in line with the offsets even with the reduced pay section,” said Paul Welch, SDX president and chief executive officer.
The company expects to achieve peak rates at the planned facility at South Disouq of 60 MMscfd of gas with its current well stock, he said. SD-3X is expected to be connected to infrastructure adjacent to the SD-1X discovery over the coming months.
Production in South Disouq is expected late in this year’s fourth quarter. SDX operates the South Disouq concession with a 55% interest. IPR Energy Resources Ltd., Irving, Tex., holds 45%.
