thank you for explaining the temporary condition of water due to acids injected into rock-and thus why it was to early to say how much water would flow under natural conditions

"Now the casing is set and perforated with acid cleaning up the perforations. The acid is injected into the rock at a pressure higher than the formation pressure. With time the acid creates water as it reacts with rock. So, high pressure water has now been added to the formation acid (also lots of CO2 comes out). This is called completion fluids. In the PR, it was stated they were in the transition of swabbing completion fluids and had just began seeing formation fluids and were disappointed in the formation flow rate circa 100 bopd. Since water from the acid is still coming out, the PR said they could not yet calculate the formation water cut. The swabbing up stroke removes the wellbore pressure and the formation fluids can momentarily flow into the wellbore with near zero backpressure. This is an ideal condition to start natural flow (not requiring a pump to keep flowing."
