Reconnaissance Energy Africa has provided an update on the Company’s portfolio of assets, including flow test sample results and flow testing operations on the Kavango West 1X Sidetrack ('KW1X') discovery well in Namibia. Additionally, ReconAfrica announces encouraging results from the soil sampling program conducted in Angola during the second quarter and continued progress of the seismic reprocessing program at Ngulu, offshore Gabon.
Highlights
- Thermogenic gas with a liquid-capable system identified: Flow test samples from the KW1X vertical test indicate thermogenic gas with maturity ranging from late oil to early gas.
- KW1X operations resumed: The Jarvie-1 rig has returned to work.
- Horizontal drilling as early as October: All regulatory amendments have been submitted. Subject to approval, drilling of the horizontal wellbore could begin in October, with flow testing to immediately follow.
- Angola petroleum system: Soil analysis on the MOU acreage suggests an active petroleum system similar to the plays on PEL 73 in Namibia.
- Gabon reprocessing on track: 3D seismic reprocessing at Ngulu is expected to be complete by year-end, concurrently a resource report will be conducted.
KW1X IsoTube Test Results
Flow test samples from the Huttenberg and Elandshoek formations in the KW1X well indicate that the natural gas collected in the samples are thermogenic with liquid potential and have maturities ranging from late oil to early gas. The upcoming horizontal test is intended to establish sustained flow rates from which additional samples will be obtained to determine liquid composition and to measure liquid yields from the gas stream.
KW1X Operations Update
In Namibia, a horizontal well will be drilled at KW1X in accordance with the continuing exploration of the Damara Fold Belt. The objectives of this horizontal well flow test are to determine deliverability of the well bore, the liquid yield from the gas stream and formation pressure response.
Required equipment has been procured and is on site or in transit. Rig maintenance is complete, and all permits have been filed with appropriate regulatory bodies for ongoing operations. The Jarvie-1 rig resumed operations and work in the vertical well bore has begun with the removal of the casing, followed by the setting of the whipstock at approximately 2,500 metres before commencement of the horizontal drilling.
Pending approvals and equipment arrival, horizontal drilling will take place in October and is scheduled to take approximately one month. The current design targets a horizontal wellbore of up to 1,000 metres to optimally intersect natural fractures across the Kavango structure. The well will be completed 'open hole', without casing or cement, to maximize flow rate from the fractures and identified porosity zones. Flow testing will occur immediately following the well completion and will be tested prior to acid wash.
Angola
Preliminary results from the soil sampling program conducted on the MOU acreage in Angola during May and June suggests there is a working petroleum system that is thermogenic with liquid content potential, similar to the Namibian side of the play. Micro seeps at surface suggest vertical migration from deep hydrocarbon accumulations. The next phase of operations will be to shoot a 2D seismic program, possibly in 2027, to outline the structural trend of the Damara Fold Belt.
Gabon
The 3D seismic reprocessing program is utilizing the most current state-of-the art reprocessing technology. This includes Full Waveform Inversion to help illuminate oil bearing reservoirs within the Loba field and the vast salt related exploration inventory on the concession. The reprocessing project is expected to be completed before year end, concurrently a resource report will be commissioned and appraisal well locations to the Loba oil discovery will be selected. Well planning has commenced for an anticipated spud.
Brian Reinsborough, President and CEO, commented: 'We are excited to be moving forward with the open hole horizontal flow test at KW1X following successfully identifying the zone of interest in the upper Huttenberg formation. Measuring a flow rate and determining liquids content at KW1X are essential for moving towards a Final Investment Decision at the Kavango discovery and will provide valuable knowledge on the potential of 22 structures already mapped on our exploration license in Namibia. We look forward to working with our partners to progress this exciting play opening discovery.'
