RE:RE:RE:might have no results for days yet
we are getting closer to a mutual understanding of the Royston intermediate sheet results
It is oil - 94% oil cut does not turn oil into water - bpd doe not turn into bwpd unless there is water. Where are you finding this water in the intermediate sheet. How can you say the entire reservoir is water throughout?
They only tested 30 feet of the lowest interval which had 270 feet of sands and 71 feet of net pay and was unbounded at TD They got pure oil. The pressurized intermediate sands kept flowing after thye moved uphole to the overthrust and they needed heavy mud to control it.
"The first and deepest Royston-1 completion and exploration test was designed to evaluate an interval at the bottom of the well in the intermediate sheet of the Herrera Formation. The completion spanned a 92-foot gross interval (30 feet of net pay) below 10,434 feet that was identified on wireline logs as being hydrocarbon bearing. Following completion and a brief clean-up period to recover load fluid, the well was shut in and built to a pressure of 3,150 psi at surface (estimated 7,100 psi reservoir pressure). The interval was then flowed up 3.5-inch tubing on a variety of choke sizes between 16/64 inches and 40/64 inches at rates up to 360 bbls/d of 34.5-degree API crude oil before being shut-in. Testing of this interval has been completed, and we are moving uphole to the well's primary production test intervals.
Although we only tested 30 feet of net pay in the lower section, we believe the results strongly suggest that all the sands encountered in the intermediate sheet (270 gross feet with 71 net feet of pay) are hydrocarbon charged. "
