Thank you for your enquiry and technical interest. I hope that this answers your question. The TE-10 mechanical stimulation was designed, planned and executed by an experienced crew of Schlumberger engineers from Algeria, drawing of specialist expertise within the Schlumberger global organisation and working alongside Sound Energy engineers and technicians. The Schlumberger HiWAY fracturing technique was indeed deployed in TE-10, the first use of this technology in Morocco. Wireline data acquired during the operations indicated that the mechanical stimulation was successful as stated in our RNS of 21 May 2019. Unfortunately, despite all our efforts, the well did not flow gas at commercial rates.
The other software mentioned was not required by the Schlumberger engineers for the TE-10 operational design, planning and execution.
WellWatcher Stim is a remote monitoring package applicable when an engineer is required to perhaps monitor the operations remotely. This is largely used in multi-well operations where an engineer or team is monitoring multiple wells off site. In the case of TE-10, the engineers were on site monitoring the stimulation although the data was streamed for analysis by Schlumberger technicians located at their technical centres.
ACTive DTS is a coiled tubing intervention using optical fiber-optic technology to collect continuous temperature profiles along the length of the well. This technology is more application to horizontal wells with multiple mechanical stimulation stations. TE-10 was a vertical well and we obtained the necessary temperature profiles with wireline.
Kinetix stimulation-to-production software is an ‘add-on’ to the Schlumberger Petrel software platform, which Sound Energy technicians and engineers currently use. Kinetix integrates geology, petrophysics, engineering, and geomechanical datasets to build a 3D simulation model of the fracture and requires a sufficiently large dataset from multiple wells for robust model calibration. The Hamra Field mentioned in the extract has multiple wells, TE-10 was a single well.
