Abstract

A new gradient scaled flooding test procedure indicated that oil is mobilized by the toe of the surfactant dispersion curve where the concentration is low, 1 to 10 ppm. Underoptimum, highly interfacially active blends of anionic and cationic surfactants were synthesized and formulated to take advantage of the displacement mechanism. Essentially all the initial or residual crude oil was removed from shaly sand packs using approximately 0.4 percent surfactant with less than 0.1 pore volume lag.

Chemical Methods for Ugnu Viscous Oils

Technical Report Mohanty, Kishore

The North Slope of Alaska has large (about 20 billion barrels) deposits of viscous oil in Ugnu, West Sak and Shraeder Bluff reservoirs. These shallow reservoirs overlie existing productive reservoirs such as Kuparuk and Milne Point. The viscosity of the Ugnu reservoir on top of Milne Point varies from 200 cp to 10,000 cp and the depth is about 3300 ft. The same reservoir extends to the west on the top of the Kuparuk River Unit and onto the Beaufort Sea. The depth of the reservoir decreases and the viscosity increases towards the west. Currently, the operators are testing coldmore »« less

Waterflood process employing surfactant and graded viscosity

Patent Dotson, B; Connally, C

A surfactant slug followed by a graded polymer flood is used to recover residual oil after waterflooding. The surfactant is a mixture of petroleum sulfonates having a median molecular weight (MW) of 400 to 430, having molecular weights from 290 to 590, no more than 10 percent by weight with an average MW less than 290 and no more than 15 percent with a MW greater than 590. The surfactant slug should contain between 1 and 2 percent sodium chloride, but be essentially free of divalent cations. Sacrificial inorganics are present in the slug to reduce the tendency of themore »« less
Waterflooding process

Patent Jones, L

Gas was injected after a waterflood, forming a gas dispersion to preferentially carry the surfactants to the oil-water interface, for enhanced oil recovery. The increased mobility of the surfactant, due to the collection of the surfactant onto the gas bubbles, decreased the amount of adsorption of the surfactant onto the reservoir rock. Foams which would inhibit the high mobility of the dispersed gas were prevented by the use of a non-foam stabilizing surfactant or combination of surfactants, and by using a low gas-water volume ratio (1 : 9 to 1 : 1). An oil external micellar system was also createdmore »« less
Waterflood oil recovery with chromatographically balanced surfactant

Patent Hill, H; Thigpen, D

A surfactant slug for tertiary oil recovery was designed to have a mobility less than the mobility of flowing oil and water in the reservoir, and the ratio of the concentrations of the surfactants to polymer thickener in the surfactant slug was adjusted so that the frontal advance rates were equal, (chromatographic balance). The surfactant slug contained sodium petroleum sulfonate (average molecular weight 460 to 470), sodium petroleum sulfonate (MW 330 to 350, Pyronate 50), Neodol 25-3S, isobutyl alcohol, a polymer thickener, and brine (about 3,900 ppm total dissolved solids--TDS, including about 400 ppm divalent cations). For the first laboratorymore »« less
Waterflood employing a viscoelastic, shear-hardening, positive nonsimple liquid with stabilizing agent

Patent Abdo, M

A soap system containing two types of stabilizing agents was effective for secondary oil recovery. The soap system was an aqueous flood containing sodium oleate, 1 percent sodium chloride, sodium hydroxide, sodium Versenate (the tetra-sodium salt of ethylenediaminetetraacetic acid), 2-ethylhexanol, and benzene. The 2-ethylhexanol and benzene were the stabilizing agents. Sodium Versenate, a chelating agent, was added to the flood to prevent formation of the calcium soap. The surfactant flood should contain no more than 100 ppm of divalent cations. Cores of Yates sand, Kermit Field, Winkler County, Texas (41.02 percent porosity, 577 md permeability) were saturated with water, floodedmore »« less
