Byron Energy is preparing to spud next week the F3 development well at South Marsh Island Block 71 in the US Gulf of Mexico, Otto Energy reported Tuesday (2 January).
The company and its joint venture partner Otto will use the F3 well as a D5 development well. The F3 well will be drilled to total planned depth of 7624ft (2324m), equivalent to 7423ft/2263m true vertical depth. Drilling is expected to take 30 days. The joint venture partners plan to drill the F3 well using the Ensco 68 rig, instead of releasing the jackup.
Byron and partners decided to move forward with drilling the F3 well based on the successful results of its F2 appraisal well. Last month, partner Otto reported that the F2 appraisal well hit four discrete hydrocarbon-bearing sands, including the B65 and D5. F2 will be cased to a depth of 7700ft measured depth (MD), 130ft MD below the base of the B65 sand.
Initial production from the field will now begin in early March 2018, one month later than planned. Once all wells are completed for production, the joint venture expects to have three wells on production, with two D5 completions in the F1 and F3 wells and one B65 completion in the F2 well. Combined initial production from these wells will take up most of the South Marsh 71 F platform production capacity. The platform can produce up to 5000 bo/d from wells in the South Marsh 71 lease.
Byron is operator of the lease with 50% working interest. Otto holds 50% working interest.
