Coalbed methane (CBM) exploration company, Tlou Energy, has achieved peak flow rates of 395 000 ft3 of gas per day during production testing of its CBM Selemo Pilot in Botswana.
Notably, the results to date indicate that the economic threshold for a potential development has been met when all key factors are taken into consideration.
In November 2014, the company started to flow gas from Selemo with the rate building as the well bore environment was gradually brought into equilibrium with atmospheric conditions.
The Selemo Pilot is the first in Botswana to flow CBM at these rates.
It is expected that as additional wells are placed nearby to the Selemo Pilot, this would assist in maintaining (or even enhancing) the longer-term gas flow rate, given a significantly larger area of the coal seam would be maintained below the gas desorption pressure.
