Tlou Energy completed coring of D3-3X, the third and final core-hole of the three well coring program and the Lesedi CBM project area, on 1 April 2014.
After finalising wireline logging operations the rig was released from all coring operations marking completion of the current program.
The core-holes intersected well-developed coal sequences throughout the Serowe, Morupule and Kamotaka formations. Coal quality and thickness results are in-line with pre-drill expectations. A total of 80 coal gas desorption tests have been captured across the three core-holes.
Samples will remain in gas desorption analysis for several weeks and will determine the gas content of the main target coal seam as well as other potential targets in surrounding coal seams. Early results for the Lower Morupule coal seam are particularly encouraging. Once gas desorption testing has been completed, a series of additional tests will be conducted on the core, including isotherm testing and coal petrographic analysis.
Lesedi CBM project
Early results from the core-holes complement Tlou’s existing knowledge of the Lesedi CBM project area. The new core-hole data will assist with initial reserves certification in the Lesedi CBM project area and the identification of future drilling sites.
