Australia-listed Tlou Energy has halted pumping at the Selemo pilot pod, at its Lesedi coalbed methane project in Botswana, to carry out remediation work.
Tlou revealed on Friday that the observed gas pressure within the Selemo pod had plateaued due to a casing integrity issue.
“With ongoing pumping operations following critical gas desorption, the gas pressure inside the casing continued to increase on a consistent upward trend,” Tlou explained in a statement to the Australian Securities Exchange.
“However, more recently the observed gas pressure has plateaued due to a casing integrity issue. Therefore pumping operations will be temporarily discontinued on the Selemo pod to remediate the issue which is currently preventing the continued build-up of gas pressure.”
The company acknowledged the remediation work would result in delays to the expected flow testing and flaring of gas at the Selemo pod, but added that it remained “very encouraged” by the rate of gas pressure build-up at the pod to date.
The Selemo pilot pod is one of two pods at the Lesedi CBM project where Tlou has previously said it hoped to start gas production testing at the project during the current quarter.
Last month the company temporarily discontinued pumping at the Lesedi pod to carry out remediation work after a recent increase in pump lift capacity did not led to the expected drawdown of water levels “due to an anomalous water influx”.
