I spend several days of the week out of cell and internet coverage, so missed the update release. The market reaction is an unsurprising surprise and seems ill informed. It appears the pressure drop from 3000 to 816 psi in 14 hours without recorded hydrocarbon flow was the catalyst.
88e had given the plan in advance, which was to deplete the reservoir pressure with natural flow prior to implementing gas lift. They have simply followed the plan and results so far are consistent with the plan
The flow rates reported will be the minute by minute rates at the times reported, not what has actually flowed over 24 hours, if you think on it how can you report a flow day rate when it has only flowed for 14 hours. So at this stage its a bit difficult to give the actual barrels recovered.
My confidence in the modelled 4000 barrels of frack fluid recovery in 10 to 14 days remains intact.
Initial gas flow was not expected, some sand and fines contamination could be expected, consequently no attempt to measure or analyse has been made. That is to come with routing through the seperator, after the return flow has proven to be reasonably clean ( seperators dont like a belly full of sand).
Until gas lift begins we are repeating last years process so should not expect much difference, it could be different as each barrel of frack fluid recovered brings us closer to good reservoir contact, but dont expect it.
With gas lift it changes to new territory, the pressure at the bottom of the well will drop but the pressure back in the reservoir pores remains at 9000 psi. The pressure gradient will be much higher and pressure gradient drives flow, higher gradient equals higher flow.
