RE: Water issue14 Dec 2019 12:40
Perched/stranded water is just that, random pockets of trapped water scattered throughout the fractured matrix. Some pockets will be larger than others and as the the oil and water is syphoned off the percentage split will vary with time on both Wells as near water pockets are depleted and new ones further away are forced into the well bores. Some areas will extracted will be more oil rich than others, i. e. fewer pockets of water. What will always be uncertain is the overall percentage split of oil/water at any one time, so the overall estimated 5 to 10 % water cut will only be confirmed when a lot more oil has been extracted. I believe it has been stated somewhere that the perched water has a different fingerprint to that of the water below oil contact, and if so this should be conclusive, as Dr T appears to be saying. This is how I see it from what I have read/digested. However, I am no expert and the above is just my opinion, from a common sense perspective. Please correct me if any of the above is a load of codswallop. ATB
