Is the skin always representative of the well damage?
ByTestWells

Well AC-2 is a gas vertical well with a permanent downhole gauge at about 650mTVDss from the top perforations. This well started production a few weeks ago and a baseline/initial PBU test was acquired to monitor the well and reservoir performance over time. The PBU test from the permanent downhole gauge is shown in the...

When the reservoir production is established, the flowlines converge towards the well with a radial geometry. This defines the most fundamental flow regime in well testing: radial flow regime. As we have seen in the post Radius of Investigation and the training course Well Test Theory and Practice, the radial flow regime is defined at...
