Blue Star Helium Ltd (ASX:BNL, OTC:BSNLF) is mobilising its rig and crew to the Enterprise 16-1 helium well in Las Animas County, Colorado, in preparation for the well workover.
BNL is an independent helium exploration and production company with a strategy to find and develop new supplies of low-cost, high-grade helium in North America
The company is preparing to start the workover of the Enterprise 16-1 well, which will set a cement plug from TD up to 1,150 feet, then run and cement 4.5-inch casing from 1,150 feet up across the Lyons formation.
This workover is expected to take about 12 days to complete and the top of the gas zone in the Lyons will then be perforated from 1,045 to 1,051 feet.
Swabbing operations will be undertaken to remove the invaded fluid from the well bore. Gas samples obtained from the Lyons formation will be sent for laboratory analysis.
About Enterprise 16-1
BNL spudded the Enterprise 16-1 well on February 16, 2022. It was drilled to a total depth of 1,250 feet and identified a potential helium zone in the targeted Lyons sandstone formation. The well was suspended for future operations.
Based on wireline logs, the top of the Lyons formation was penetrated at 1,045 feet with an interpreted gas water contact (GWC) intersected at 1,058 feet (equating to an approximate 13 feet gross and net gas column in the well bore).
Some helium gas was seen while drilling, however, due to subsequent water invasion, no test was able to be conducted at the time to obtain a gas sample for compositional analysis.
Data from the drilling and logging at Enterprise has been integrated into the geological model and prospect mapping.
The new information as well as the gas seen on logs in the Hill#2 well 1.3 miles east on the Enterprise structure has resulted in greater certainty of the closure at Enterprise which will be followed up with future drilling.
This will include an exploratory water well similar to those that have resulted in discoveries at Voyager, Galactica and Pegasus and follow-up helium appraisal and development wells.
