Byron to bring Gulf of Mexico well in production in two weeks

Byron Energy has completed operations on its SM71 F4 well in the U.S. Gulf of Mexico and began working on final hook up with production expected in two weeks. Furthermore, Byron has started drilling operations on the F5 well to further develop the D5 Sand reservoir.

Byron anounced on February 13, 2020, that its operated SM71 F4 well had reached a final total depth of 8,130 feet Measured Depth (MD) (7,570 feet True Vertical (TVD)) and logged 91 feet of net hydrocarbon (87 feet true vertical thickness net hydrocarbon) pay in the primary target D5 Upper Sand.

Since then, the D5 Upper Sand was perforated over a 100-foot measured depth interval and frac pack sand control measures were implemented in the wellbore, Byron said in an update on Wednesday.

As of 0600 hours USCT on March 2, 2020, completion operations on the SM71 were finished, Byron said.

Presently, crews have begun hooking the well up to the SM7 F Platform production system and Byron anticipates that the well will be placed into production in two weeks.

Byron further informed that the Enterprise 264 jack-up rig had started work on the SM71 F5 well and the rig was preparing to run 24” drive pipe leading to the actual spud of the well.

The SM71 F5 well has a planned total depth of 8,788 feet MD (7,768 feet TVD) and is expected to take 25 days to drill and evaluate. If the well is successful, completion operations will follow immediately and are expected to take another 14 days. The well would then need to be hooked up to the production system before production can begin.

The objective of the SM71 F5 well is to test a portion of the D5 Sand reservoir that may be poorly drained, if at all, by the SM71 F3 well. The primary D5 Sand has now produced over 2 million barrels of oil, water free, from the Byron operated SM71 F1 and F3 wells since March of 2018.

Byron is the operator of SM71 and currently has a 50% working interest and a 40.625% net revenue interest in SM71. Otto Energy holds the remaining interest in SM71.

Otto elected not to participate in the SM71 F4 well, giving Byron a 100% working interest with an 81.25% net revenue interest in the SM71 F4 well. However, as previously reported, Otto decided that it would be participating in the drilling of the SM71 F5 well.

Byron’s CEO, Maynard Smith, said: “The drilling and completion operations on the SM71 F4 were carried out in a very safe and efficient manner and indications from the completion job are that we should anticipate a mechanically sound completion across the D5 Upper Sand. We would like to thank Enterprise’s offshore crews, our many vendors, wellsite leaders, drilling and completion engineersfor the outstanding job they have done on the F4 well despite the offshore weather conditions. We look forward to a similar experience with the F5 well.”
