Byron Energy Ltd. announced that the Byron operated OCS G-34266 #F3 development well ("F3") is currently drilling ahead at 668 feet Measured Depth ("MD"). The SM71 F3 development well will be drilled to planned total depth of 7,624 ft/2,324 metres MD, equivalent to 7,423 ft/2,263 metres true vertical depth ("TVD"). F3 is expected to be drilled and evaluated by early February 2018. Operations on the F3 commenced over the weekend, after 7 5/8" casing was run on the SM 71 F2 appraisal well, which is now temporarily suspended prior to B65 perforation and completion procedures. Completion operations on all wells will commence sequentially once drilling of the F3 is finished. As previously reported, SM71 F2 appraisal well encountered four discrete hydrocarbon bearing sands, including the B65 and D5. The SM71 F3 well is designed to intersect the D5 Sand very near the point that the F2 well intersected the D5 Sand which logged 117 feet of True Vertical Thickness ("TVT") oil pay. The F3 well will provide a second take point in the D5 Sand reservoir in addition to the F1 well (91 ft TVT oil pay), which was drilled in 2016. The engineering design of the F3 well has a borehole angle of 24 degrees resulting in shorter measured depth than the F2 well which had an angle of 60 degrees. The design will also provide an optimal completion configuration in the reservoir. Byron announced that final pipeline tie-ins from Byron's SM71 F Platform to oil and gas sales lines have now been fully completed in the field. Instrumentation and electrical crews are also working on the SM71 F platform daily to complete facility work and ensure a timely transition from drilling to production when the Ensco 68 rig leaves location after drilling and completion operations are finished.
