viper, There can be no meaningful "test" pressure measurements yet. Typically, bottomhole pressure recorders are run to and "hung" in the bottom of the well only after perforating the casing and doing a short "cleanup flow". The recorders will measure the pressure of the fluids in the perforated zone prior to any significant production from the zone. Pressure is then measured continuously during the flow test (Presumably a 4 Point Modified Isochronal Test, but not necessarily!!) and then also during the subsequent shut-in period. The pressure data gathered during such a test is then analyzed to provide several different pieces of useful information which help guide future development. BUT, THEY HAVE NOT YET PERFORATED & THEY PROBABLY WILL NOT PERFORATE FOR AT LEAST 60 HOURS (i.e. Sunday, earliest!!). So, the only pressures that they can be measuring now are "operational" in nature to tell them things like: - Is the tubing plug holding? - Do we have a tubing leak? - Is the packer properly seated and providing a "seal" in the casing? Pressures measured for these purposes are a part of completion operations. They are not a part of the flow test. Remember, they are completing a zone that is 2.8 miles deep!! Things take time and shit happens (Eg. If the packing element of the packer gets damaged running in to ~14,000 ft then when they go to set it, it may not provide hydraulic isolation between the tubing and the annulus. So, what do they have to do?? Right. They pull out 14,000 feet of tubing, 90 feet at a time, replace the packing element, run back in 90 feet at a time and hope to hell that it this time it works. But if it doesn't then out it comes again and....) There is nothing "wrong" just because we can't yet see a flare. We can't realistically expect one until late Sunday at the earliest, maybe even Monday, or possibly Tuesday, or.... If I don't see a flare when they've been perforated for 24 hours then I'll start to develop a head of white hair. Until then, I'll keep the present color. Hope this helps. Later, grayhairs
