Tlou Energy, the ASX, AIM and BSE listed company focused on developing gas-to-power projects in southern Africa using coal bed methane (‘CBM’) natural gas from its gas field in Botswana, has provided an update on field operations at its Lesedi CBM project.
- Vertical well ‘Lesedi 3P’ has been drilled and reached a total depth of 575m
- Drilling has commenced at the second vertical well ‘Lesedi 4P’ which was spudded on 4 November 2018
- Program aims to provide gas flow data in the area where the initial project development is proposed
Update of Drilling operations
As previously announced Tlou Energy commenced drilling operations at the Lesedi CBM Project, with the first well, ‘Lesedi 3P’ being spudded on 16 October 2018. This vertical production well has been drilled successfully and reached a total depth of 575m.
Wireline logs were acquired over the open hole interval of Lesedi 3P. The well intersected the Lower Morupule coal seam, which is the target seam for dual lateral wells, planned to be drilled for approximately 700m in-seam, which will then intersect with Lesedi 3P.
The rig was released from location on Friday 2 November and then set up at the Lesedi 4P location. Lesedi 4P was spudded on 4 November 2018. Operations at Lesedi 4P will follow the same program as for Lesedi 3P. The well is planned to be drilled to a proposed total depth of approximately 580m.
Background on Drilling program
Tlou will drill the Lesedi production wells as ‘dual lateral pods’, comprising a single vertical production well intersected by two lateral wells. This will be followed by production testing with the potential to ultimately convert a significant portion of the currently established gas resources to reserves and to deliver gas to a proposed central processing facility and power station located in close proximity.
The vertical wells along with the top-hole (vertical) sections of the lateral wells are being drilled first. Thereafter, the lateral sections of the wells will be drilled using specialist directional drilling equipment.
Once drilled, the wells will then be completed using a separate workover rig and surface facilities installed. Production start-up is targeted to commence in early 2019. The wells will be on production for an extended period of time to de-water and lower the pressure in the coal seam to achieve gas flow.
