With the first string of casing set and cemented in the 6-1 well, the company owned and operated 1000 HP rig (Jarvie-1) is drilling ahead to a target depth of 3800 m (12 500 ft). The 6-1 well is designed to evaluate the petroleum systems discovered in the first well (6-2) in an area of maximum thickness. These first two wells are within one of five major sub-basins of the larger, more laterally extensive, Permian aged deep Kavango Basin.
The company will take whole core, side-wall core and conduct a full logging suite of all zones of interest (conventional targets and source rocks). As with the 6-2, a comprehensive state of the art logging programme over both sections will be provided by Schlumberger. In addition, a Vertical Seismic Profile (VSP) will be run to enable the most accurate tie-in possible, of well data, to the 2D seismic programme scheduled to commence in June 2021.
ReconAfrica is using the Polyamine drilling fluid system, provided by Valence Drilling Fluids, which uses freshwater as the base fluid. The plant-based products added to the base fluid are created through an organic process and are biodegradable. Not only is this water-based drilling fluid 100% safe to the environment, it provides ideal samples (cuttings and core) to be utilised to determine a range of petroleum properties and locations for future exploration and production wells.
ReconAfrica is engaged in the opening of the newly discovered deep Kavango Sedimentary Basin, in the Kalahari Desert of northeastern Namibia and northwestern Botswana, where the company holds petroleum licenses comprising approximately 8.5 million contiguous acres.
