ABSTRACT:
A method is provided for modifying an original distribution pattern including an original central injection well and four original corner production wells. One or more new injection wells are provided at locations approximately aligned midway between adjacent ones of the original corner production wells. In addition to the two original corner production wells between which it is located, there are associated with each new injection well four additional new production wells. A first pair of these new production wells is provided at locations substantially aligned between and preferably substantially midway between the original central injection well and the two adjacent ones of the original corner production wells. A second pair of new production wells is located substantially as a mirror image of the first pair about an imaginary straight line between the two adjacent ones of the original corner production wells. This forms a new seven-spot pattern having its new injection well located substantially in the center of an area which was relatively unaffected by the original fluid distribution pattern.
