Basics of "wells"23 Sep 2022 08:43
Noting some of the recent chat from investors who might not have direct experience of wells.... Wells are holes into porous rock. Often many different layers (or zones) of rock. Each layer of rock might have different contents and pressures. There is only so much that can be done from exploration drilling and modelling and then you start production and see what happens. There is a lot that can be done to isolate zones to determine where a problem may lie and then plug it by a sleeve or packer ... but generally on a reactive basis.
I don't have any direct info on what is going on in IOGs well but the saline issue is not unusual.
