Pboo,
Onshore Wells are named after a nearby surface feature, which is usually the nearest village / wood / farm (e.g. Singleton, Humbly Grove, Palmers Wood, Wytch Farm etc), not the subsurface formations that they are targeting.
The Kim Field is in the Hampshire Basin, not the Weald.
Kim-1 was drilled by BP in the late 1950's and put on production in 1961. They drilled three more appraisal Wells in the area at the time, which failed to find any more commercial oil.
Kim-1 produces from the Cornbrash Formation, which is Middle Jurassic in age. The Kim is Late Jurassic and is above (not below) the Cornbrash. The Kim actually outcrops along the coast in the area and there are a couple of well known oil seeps on it too.
However, it is not the source of Kim-1 production, which is being fed by a fracture network from somewhere beneath the Cornbrash.
In 1980 BP realised that the field had produced more oil than the mapped structure could possibly hold and so must be being charged from below, which led them to drill Kim-5.
Unfortunately that Well not only failed to find any deeper accumulation, it also messed up the Kim-1 Well (accidentally cemented it up during a casing cement job on Kim-5) which had to be worked over as a result.
Fun Fact;
The main target for Wells in the Hampshire was the Bridport Sandstone. The majority of the licences were operated by BG, with BP as 50% partners.
BG realised that there might be oil in the Sherwood at a particular location and proposed deepening the Well to find out. BP disagreed, so BG decided to sole risk and drill ahead. Just before the Sherwood was reached, BP changed their minds and bought back in.
The Well was the discovery Well for Wytch Farm and BG were going to be the Operator until forced by the Govt to sell their 50% to the Dorset Bidding Group, which resulted in BP becoming the Operator.
Waste of skin: I can't be bothered dealing with your FOOLish fantasies any more - binned and reported.
