TransGlobe Energy’s NW Sitra 9 (NWS 9) exploration well in the Western Desert failed to encounter hydrocarbons for the company. The well was drilled to a total depth of 5,950 ft and abandoned as a dry well.
Although disappointing, TransGlobe said the NWS 9 has provided key information that will be integrated into the regional database and prospect mapping for the area. The NWS 9 well cost was around $1.0 million to drill and abandon.
The rig has been moved to the South Ghazalat concession to drill two Cretaceous targets. The first of the two wells to be drilled is the South Ghazalat-1 exploration well.
A larger 2,000 HP drilling rig is rigged up on the NWS 12 and is expected to commence drilling shortly, following the close out of acceptance testing. NWS 12 is targeting a deeper stacked Cretaceous/Jurassic prospect with a planned drilling time of approximately 60 days.
The company requested and received a six-month extension to the first exploration phase (now expiring January 7, 2019) in NWS to drill and evaluate the Phase 1 exploration commitment wells (NWS 9 & 12). Prior to January 7, 2019, TransGlobe can elect to enter the second and final exploration phase (3.0 years after the extension of phase one), which has a two well ($6.0 million) work commitment and a mandatory relinquishment of 30% of the original concession area not held by development leases.
In Egypt’s Western Desert the company mobilized a third drilling rig and is preparing to drill the first of three planned development wells. In the West Bakr, drilling is expected to commence on the M-North well. M-North is the first of two wells targeting the producing Asl formations in the M field. Following the M wells, the drilling rig will move to NW Gharib to drill the NWG 38A-7.
The NWG 38A-7 well is targeting the 38A Red Bed pool in a structurally lower position as a potential water injector approx. 0.4 kms south of the NWG 38A Injector well, drilled in Q2, encountered 92 ft of Red Bed with an internally estimated net oil pay of approximately 34 ft. The NWG 38A Injector well was completed and confirmed oil in the lower portion of the Red Bed.
The NWG 38A Injector well will require a fracture stimulation prior to producing (similar to NWG 38A-1). Should the NWG 38A-7 well also encounter an additional oil column, the company has planned an additional well further south at NWG 38A-8 as a contingency for reservoir pressure support.
In addition, production from the four well (Arta 48, Arta 54, NWG 1AX, NWG 5X) stimulation program completed during May/June targeting Nukhul and tight Red Bed conglomerate wells, has averaged approximately 775 bpd during the respective first 30 days of production after recovering frac fluid.
