Source problems scupper SDX well

27 February 2017, Week 08, Issue 728

The KSS-2 well in Morocco’s Sebou permit found gas but is considered to be non-commercial. Announcing the result, SDX Energy on February 21 said this was the sixth well in its current campaign, which has provided four commercial discoveries. There are three wells still to be drilled, it said. 

The KSS-2 found eight net metres of high-quality reservoir interval in the Gaddari and Guebbas sequences, at a depth of 1,293 metres, with average porosity of 30%. The well failed, though, as gas saturation was low. The well will be plugged and abandoned, with the rig moving on to the SAH-2 location. 

While this result is disappointing, SDX said that it should not have an impact on its production plans, given other successes in the campaign. Earlier this month, the company reiterated a gross production target of 226,560-283,200 cubic metres per day by the end of 2018. The comments came in a statement saying its ONZ-7 well had flowed at a rate of 283,200 cubic metres per day. When producing into the local infrastructure it is likely to flow at a lower, more sustainable rate, but this demonstrates the strength of SDX’s Sebou licence. 

SDX went on to say the KSS-1 well may have failed as the prospect was on the upthrown side of the main bounding fault in Ksiri. This, it said, appears to have isolated the well from the main source rock. 

The next well, SAH-2, is on the downthrown side of the fault. As such, the well has a better chance of having a commercial charge. 

The company’s president and CEO, Paul Welch, hailed the use of directional drilling on the well. “Whilst KSS-2 was not successful, our belief is that this result proves that the main bounding fault provides a good seal and therefore gives us a further confidence in the forthcoming prospects. We are looking forward to drilling the final three wells in this programme and reporting on their results in due course,” he said. 

SDX has a 75%stake in the Sebou licence, in the Rharb Basin. The company said it had encountered problems with the top drive on the rig in a statement on February 13.
