OPTIMIZATION OF WELLS' OPERATIONAL MODE BY SATURATION PRESSURE
Activities undertaken in Olkhovsky oil field illustrate the fact that maximum effect of showings obtained during an oil field development is reached when bottom hole operational pressure of a producing well is lower than saturation pressure. The limit of allowable decrease of bottom hole pressure lower than saturation pressure, characterized by minimum losses of oil recovery coefficient under maximum oil extraction rate is defined. Some activities meant for prevention of isolation of oil reserves, being drained at the moment, by free gas liberation in formation conditions and for recovery of wells productivity are suggested.
