TE-4 well will be drilled as a vertical well to prove we can flow the well to surface prior to fracking the well. We will possibly be using a smaller rig to drill the vertical well as we will need the bigger rig to complete the horizontal drill if the well flows to surface. The big problem is the well was drilled in the incorrect position next to a fault within the reservoir. Also the carbonate cementation encountered.
Whilst Sound has strategically prioritised its gas monetisation strategy through the phased
development of the TE-5 Horst (Tendrara Production Concession), the Company has continued
to re-evaluate the extensive exploration portfolio within the Greater Tendrara and Anoual
exploration permits surrounding the Tendrara development. By integrating the acquired data
and learnings from previous drilling campaigns with acquired and reprocessed seismic datasets, the Company had high graded several potential near term subsalt drilling opportunities within the Trias Argilo-Gréseux Inférieur ("TAGI") gas reservoir, the proven reservoir of the TE-5 Horst gas accumulation. These drilling opportunities include the exploration prospect 'M5' located on the Anoual exploration permit, together with the SBK-1 and TE-4 structures that previously encountered gas shows in the TAGI reservoir on the Greater Tendrara exploration permit.
The estimated (P50) 260bcf gas-in-place TE-4 structure, which is the fault block adjacent to the
TE-5 horst development, was tested in 2006 but did not flow gas to the surface. New seismic
imaging suggests the TE-4 well location was suboptimal, at the spill point of the structure and
potentially within the transition zone of a gas column. Sound plans to drill on the crest of the
TE-4 structure, with the objective of locating higher quality reservoir lacking the pervasive
carbonate cementation encountered in the original well. Additionally, the TE-4 Horst is located
c.5km from the planned Tendrara phase 1 & 2 production facilities. The estimated (P50) 130bcf
gas-in-place SBK-1 structure flowed gas to surface during testing in 2000 at a peak rate of
4.4mmcf/d post acidification, but was not tested with mechanical stimulation. Recent analysis
suggests the well was also located sub-optimally, close to a fault and in a small compartment.
Jobbinscl…the reason they are going after TE-4 is because it is the closest and fastest to production at 5km from the planned Tendrara phase 1 & 2 production facilities.
i-man
Surely we don't have to wait for every i to be dotted and T crossed with Calvalley, regarding Phase2, before an agreement can be made to drill the new Te4 ? Well it is Calvalley paying for the well…..What would you do.
