Pure Hydrogen has upgraded resources at its Serowe coal seam gas project in Botswana after integrating results from the Serowe-2 and Serowe-3 wells.

Third-party certified best estimate contingent (2C) resources have been increased from 23 billion cubic feet to 160.6Bcf while best estimate prospective resources are up from 6.08 trillion cubic feet to 10.07Tcf.

Serowe-3 had encountered 41m of interpreted gassy coal seams with free gas breaking out of fluids on the surface. A new logging method showed adsorbed gas, free gas and indications of permeability in several of the target coal seams.

Pure Hydrogen (ASX:PH2) is currently drilling the Serowe-4 well and is currently preparing the site of the Serowe-5 well for drilling.

Both Serowe-4 and Serowe-5 are step-out appraisals of the Serowe-3 well, whose interpreted natural permeability and high gas contents in the thicker coals encountered have substantially reduced the risk and cost of a commercial development using inexpensive vertical well completions.

“The continuation of the multi-well appraisal program across the Serowe Gas Project is progressing with very encouraging results to date, particularly the much thicker gassy coal seams in Serowe-3,” managing director Scott Brown said.

“With step-out drilling and Serowe-3 flow testing commencing shortly, we expect additional positive news flow on the Serowe gas project’s progress where we are free-carried.

“Work is also advancing favourably across our hydrogen portfolio and as we have advised, the Serowe Gas Project could ideally be a feeder to create hydrogen supply for Botswana.”

Pure Hydrogen is free-carried by its partner Botala Energy on the first $6 million expenditure in the Serowe Gas Project.
