This is a superb post from a highly knowledgeable poster who now sees HUR as an investment once more rather than a pure spec play and points a possible way forward for Lancaster -
'Additional development drilling on Lancaster doesn't even have to access additional reserves. Simply accelerating the already identified reserves has a huge positive impact for a couple (or more) reasons.
Not least.. by accelerating extraction, the reserves can be evacuated sooner, and thus reduce the not inconsiderable cost of keeping the AM on station. The most economic way to produce from a field is as fast as possible (within limits) and then shut in... There is little benefit in "stretching out" production over many years .... unless of course you're drawing a salary from it...!!
Secondly, a second producer would enable some production to continue to the AM even if the W6 ESP(s) fail. As it is, a failure here would render the AM useless for the period that new ESP could be installed.. and that could be months subject to rig availability/weather.
If sidetracking W7, one of the first procedures would be to pull their ESP's... they could then be refurbished and be ready for immediate use if required in W6. We know that at least one of the W7 ESPs is fully operational since it was used during the recent 2-day test; (at 96% water cut, there is no way the well would have flowed naturally..)
Development of Lancaster further from the existing well locations would almost certainly access ADDITIONAL reserves, but it would entail significantly higher costs, with new flowlines, umbilical, well-head, and top-hole drilling, all of which would be avoided by sidetracking, not to mention the additional risk in venturing into geologically less know region.
HUR has been given a new lease of life with the higher oil price... we should not squander this life-line, as we are STILL on life-support, IMHO..
btw, thinking about the recent W7z well test: this clearly demonstrated that the wells ARE able to PUMP at very high water-cuts... This should allow full extraction of economic reserves, ie. until the opex exceeds revenue... which could allow operation for a couple more years than currently suggested by the company'
