Phase 1 rigless testing update
Highlights
· Phase 1 rigless testing with small perforating guns confirms formation damage
· Phase 2 Sandjet testing, always the preferred perforating option, will proceed with design parameters modified to take into account the depth of formation damage
· The Company is confident that Sandjet will achieve its objective to establish gas flow
· Analysis of gas samples confirms up to 99.57% methane suitable for CNG development
· MOU-5 Jurassic well planning on track
· No change to available discretionary working capital to carry out Sandjet testing programme
Predator Oil & Gas Holdings Plc (LSE: PRD), the Jersey based Oil and Gas Company with near-term operations focussed on Morocco and Trinidad, provides an update on its Phase 1 rigless testing programme onshore Morocco.
Phase 1 rigless testing programme.
Objective
The Phase 1 rigless testing programme was designed to confirm potential formation damage caused by heavy drilling muds used whilst drilling and estimate the minimum depth of penetration of drilling mud into the potential reservoir formations.
This information was critical for designing the Phase 2 Sandjet programme, including perforating parameters, and for evaluating additional potential reservoir intervals interpreted by NuTech but where conventional wireline logs were potentially impacted by deep invasion of drilling mud into these intervals.
In order to carry out Phase 1 rigless testing, conventional 111/16" perforating guns, being the only option available at the time to allow Phase 1 rigless testing to commence before 5 February 2024 and the end of the extension of the Initial Period of the Guercif Petroleum Agreement facilitated by Amendment #3, were used.
It was recognised that the perforating guns were likely to be under-sized but a third party analysis indicated a maximum 12" penetration into the reservoir formation versus their interpreted zone of formation damage for the TGB-2 Sand in MOU-1 of 8".
Therefore it was assessed that the Phase 1 rigless testing programme would at least establish a minimum extent for formation damage around the wellbore of 8 inches based on the above third party information. This would assist in designing more appropriate Sandjet perforating parameters.
Operations summary
Phase 1 rigless testing operations commenced on 10 February 2024 after arrival at the well
site of the explosives required for the perforating guns and allowing for adverse weather
conditions caused by severe gusts of wind that prevented crane work to ameliorate.
All four zones in MOU-1 and MOU-3 to be tested were perforated and operations were completed on 19 February 2024 with the crews and equipment being demobilised. Operations took 10 days
