ABSTRACT:
Steam is injected in a multi-spot pattern in a dipping reservoir. The injection point of that steam is downdip and is offset from the pattern center by at least one-fifth the distance from the pattern center to the downdip producer row of that pattern. Preferably, the amount of offset is between two-fifths and three-fifths the distance from the pattern center to the downdip producer row.
