Abstract: A method for enhancing the recovery of petroleum from an oil bearing formation during injection of a non-condensible gas comprises the at least periodic injection of a foam forming composition or a preformed foam into the reservoir. The foam which is produced comprises a mixture of a non-condensible gas, water and a non-ionic surfactant. The non-ionic surfactants which can be employed in the present invention are those non-ionic surfactants which have a HLB value of about 14 to less than 20, preferably 15-18, and which provide a stable foam when the surfactant is mixed with brine and/or water and a non-condensible gas. The method is preferably employed within a light oil bearing carbonate formation.

Abstract: A method and apparatus determines three phase holdup fractions and flow rates for the individual phases of a fluid flowing in a well. A logging tool comprising a temperature compensated gradiomanometer having a differential pressure detector comprised of two pressure sensors and a nuclear densitometer having a beam source is lowered into a wellbore. The differential pressure between the pressure sensors is measured and an average fluid density is determined. The attenuation of a beam propagating from the beam source through the fluid and to the beam detector is measured, and holdup fractions of the fluid are calculated. Flow rates for the individual phases are determined by adding a flowmeter, and multiplying each holdup fraction by the total flow rate.
