Byron Energy: sand recompletion update

Published by
Oilfield Technology,

The entire B55 Sand section was perforated over a 22 ft measured depth interval which equates to 11 ft of true vertical sand thickness. After perforating the B55 Sand, the well was flowed back to the production system and rates of 382 bpd (99% oil cut) and subsequent shut in tubing pressures of 1152 psi were observed.

At the end of the flowback, a small amount of sand was produced and subsequently washed out with coil tubing prior to sand control operations. Sand control measures were performed last week and since then the well has had difficulties unloading the completions fluids and stable oil and gas production rates have yet to be established. To date, approximately 300 of the 458 bbls of completion fluids have been recovered on flowback from the formation along with 220 bbls.The well is currently flowing at an unstabilised rate of 150-200 bpd and we expect the well to continue to unload and stabilise over the next couple of weeks.

The liftboat and personnel have been demobilised to Fourchon, Louisiana and operations on the SM71 F platform have returned to normal. Byron’s production operators are supervising the continued unloading of the SM71 F2 well.
