Blue Star Helium (BNL) has begun mobilizing drilling equipment and personnel for the Enterprise 16-1 helium well in Colorado as it prepares to begin workover of the well.

As part of the workover process, the company will install a cement plug from 1,150 feet before running 4.5-inch casing from that depth through the Lyons Formation into the well.

Blue Star will then puncture the top of the gas zone from 1045 feet to 1051 feet. The company said it would undertake swabbing operations to remove the invaded fluid from the wellbore.

The company said it expected the workover process to take about 12 days, with gas samples from the Lyon formation to be sent for laboratory analysis.

Blue Star dug the well in February, drilling to a total depth of 1,250 feet and identifying a helium zone in the Lyons formation.

During this drilling, helium gas was identified but could not be tested due to subsequent water invasion.

Blue Star Helium shares were trading up 3.7% at 2.8 cents each at 11:50 a.m. AEST.
