Predator Oil & Gas Holdings Plc has successfully completed the drilling and logging operations for Morocco’s MOU-3 well appraising the Moulouya Fan primary reservoir target and several secondary reservoir targets encountered in MOU-1 drilled in 2021.
A preliminary summary of the results from the zones of interest is given below pending further NuTech petrophysical wireline analysis that will be commissioned ahead of finalizing multiple intervals for rigless testing.
No logs were acquired over the shallow interval, the results for which were previously announced, which are behind 95/8” casing.
Within the interval from 815 to 895 meters TVD MD five potential sands with gas shows were encountered. Individual sands have a maximum thickness of 3 meters giving an estimated cumulative thickness of 11.5 meters versus a P10 pre-drill forecast sand thickness of 10 meters.
The Ma Sand had a 3% formation gas show.
Pre-drill P50 structural closure was determined to be 6km² for the area tested by MOU-3.
MOU-3 well results have confirmed that the Ma to TGB-6 interval can be correlated with the same gas-bearing interval in MOU-1, approximately 7 kms. to the southwest. The two well data points now support a seismically defined sequence covering an area of up to 58 km² that potentially forms a combined structural and stratigraphic trap for gas.
Several thin sands of up to one meter in thickness were encountered in TGB-4 from 1046 to 1070 meters TVD MD. Borehole geometry was poor and further detailed petrophysical analysis will be required to determine reservoir quality. At least one of these sands may be a candidate for rigless testing.
From 1112 to 1140 metres TVD MD. five thin sands, individually up to one meter-thick, were encountered. As for the TGB-4 sands further detailed petrophysical analysis will be required to determine reservoir quality. Rigless testing of at least one sand will be considered.
The Moulouya Fan sand was encountered from 1378 to 1437 meters TVD MD with approximately 50.5 metres of sand versus a pre-drill P50 forecast of 19 meters.
Elevated background gas readings were recorded whilst drilling this section.
The interval correlates with the Moulouya Fan interval penetrated by MOU-1 drilled 7 kms. to the SW and its presence supports the development of the Moulouya Fan over an area of at least 30km².
A rigless well test over a gross interval of 43 meters within this section between 1379 to 1422 meters TVD MD is planned to be carried out.
MOU-3 reached its planned Total Depth of 1,509 meters TVD MD on 21 June 2023.
Wireline logs were run as per the pre-drill logging program. 41/2” casing was run to the casing shoe at 1494.5 meters TVD MD. The well has been completed for rigless testing.
Forward plans
Star Valley Rig 101 has moved on to the MOU-4 well location and drilling operations are anticipated to commence shortly. MOU-4 will be targeting the same sequence of the Moulouya Fan as was found in MOU-3. In addition, this well will test the potential for Jurassic carbonate reservoir development within a 126 sq km structure.
Following NuTech petrophysical analysis of the wireline logs from MOU-3 the proposed rigless testing program will be updated to include new zones identified in MOU-3.
Paul Griffiths, Executive Chairman of Predator Oil & Gas Holdings Plc commented: “The MOU-3 well has validated our pre-drill upside forecast for sand development in respect of the main Moulouya Fan target. A gross interval of 43 meters will be evaluated by a rigless well test.
“It has increased our inventory of potential gas reservoirs for a CNG development with the discovery of very shallow over-pressured gas. It has demonstrated the possible continuity, subject to rigless testing results and a future infill well, of gas sands penetrated in MOU-1 with similar sands encountered in MOU-3. In particular the Ma Sand potential has been enhanced over a wider area with the possibility of a larger gas trap being effectively sealed covering up to 58km². The shallow gas potential of MOU-3 has exceeded all pre-drill expectations.
“The focus will now be on drilling and completing MOU-4 where we do not expect shallow gas to be present. Targets are the Moulouya Fan and the so far unknown potential of the Jurassic carbonates within a very large structural closure. Once the MOU-4 drilling is complete, results from all the wells drilled in 2023 will be quickly assessed and compared and a comprehensive and expanded rigless testing program will then commence during July.”
