Pure Hydrogen to drill more wells in Botswana
Australia’s Pure Hydrogen and its partner will drill the first of the two further appraisal wells at the Serowe coalbed methane (CBM) project in Botswana next month, it said on August 25.
Pure Hydrogen said its partner BotsGas has advised that Serowe 4 will be spudded in mid-September with a short-term flow testing of Serowe 3 to occur prior to the drilling of Serowe 4.

“Serowe 3 encountered 41 m of gassy coals. This total coal thickness is more than double the pre drilling estimates. While drilling, free gas was breaking out of drilling fluids on surface,” it said. “The processing of a new logging method showed adsorbed gas, free gas and indications of permeability in several of the target coal seams.”
It added that the interpreted natural permeability and high gas contents in the thicker coals encountered in Serowe 3 meant that the risk and cost of the commercial development of a multi-trillion cubic feet project in central southern Africa could be substantially reduced using inexpensive vertical well completions methods.
Pure Hydrogen currently has 100% of project Serowe and is free carried to 51% with partner BotsGas funding the farm-in appraisal programmes. The companies signed a joint operating agreement for the Serowe project in December last year.
