    摘要: Petroleum sulfonates useful to impart micellar characteristics to mixtures of hydrocarbon and aqueous medium are obtained by reacting a hydrocarbon gas oil feedstock (average molecular weight 250-700; A/AP aliphatic to aromatic proton) ratio 5-50 moles/mole, 30-100% of the feedstock molecules contain aromatic portions and the A/AP ratio of the aromatic portion being about 3-20 moles/mole) with a solution of EDC (ethylene dichloride) containing 0.1-0.3 lb. liquid SO.sub.3 /lb EDC. The SO.sub.3 concentration is about 0.1-0.3 lb. of SO.sub.3 /lb of gas oil feedstock. Reaction takes place in a back-mix tubular reactor wherein at least about 4 parts of reaction products are recycled per 1 part of reaction products withdrawn and wherein the gas oil feedstock plus recycled reaction products and the SO.sub.3 /EDC streams entering the reaction zone are in turbulent flow. Velocity ratio of the feedstock plus recycled reaction products stream to the SO.sub.3 /EDC stream is at least 4:1, respectively. The withdrawn reaction products are neutralized with an aqueous basic liquid, e.g. aqueous solution, NH.sub.4 OH and thereafter the EDC is recovered from the neutralized reaction products to obtain unextracted sulfonate mix. The unextracted sulfonate mix is extracted with an aqueous alcohol solution to obtain a raffinate phase, an extract phase, and a brine phase; the extract phase is withdrawn and stripped of alcohol and water to obtain the desired petroleum sulfonate.

    摘要: Petroleum sulfonates are obtained by continuously contacting whole crude oil or topped crude oil with gaseous sulfur trioxide (contains as a diluent sulfur dioxide and light hydrocarbon vapor) in a reaction zone operated at a temperature of 120.degree.-250.degree. F. and a pressure of 3-50 psia. The reaction product is then passed to a vapor-liquid separating stage where a vapor stream is separated and a portion of it is recycled back to the reaction zone; a liquid stream is separated from the separating stage and a portion of it is recycled back to the reaction zone. The remaining portion of the liquid stream is neutralized with a monovalent inorganic base to obtain the petroleum sulfonate. The petroleum sulfonates are particularly useful to recover crude oil from subterranean reservoirs.

    摘要: Flooding of a subterranean formation with micellar dispersions containing petroleum sulfonates obtained by sulfonating whole or topped crude oil is improved through the use of a micellar dispersion of a predetermined viscosity containing an amount of cosurfactant in excess of that required to cause the micellar dispersion to have the highest viscosity possible for the particular micellar dispersion with the particular cosurfactant used. Preferably, the cosurfactant is an alcohol and the cosurfactant concentration is sufficiently high to control the micellar dispersion to have a predetermined mobility when injected into a hydrocarbon-bearing formation.

    摘要: Improved oil recovery by flooding subterranean formations with micellar dispersions; comprised of hydrocarbon, water, cosurfactant, electrolyte, and petroleum sulfonate obtained by sulfonating whole or topped crude oil; is obtained by incorporating within the micellar dispersion about 1.5 to about 4.5 wt. % of active sulfonate groups (e.g. --SO.sub.3 NH.sub.4 or --SO.sub.3 Na) which are attached to the petroleum sulfonate. The micellar dispersions of this invention contain an amount of cosurfactant in excess of the amount required to produce a viscosity maximum with the particular micellar dispersion.

    摘要: Flow control of diluted polymer solutions is effected by utilizing positive-displacement flow devices such as gear pumps to withdraw flow energy in the form of shaft work. Control is obtained by varying the nature and amount of shaft work withdrawn, such as by operation of an electrical generating system, and the work so created may be used to provide operating power to a control system.

    摘要: This invention relates to a method of completing a well that penetrates a subterranean formation and more particularly to a method for screen placement during proppant packing of formation perforations or fractures created by hydraulic fracturing techniques. The top of the screen is placed at a sufficient distance below the top of the perforations such that the frac pack pumping rate does not bridge off at the top of the screen when the frac pack is being pumped.

    摘要: A method of gravel packing a well. A flow-reducing material is introduced into the annulus between a tubular liner and the well bore so as to collect at the perforations in the well bore and the apertures in the liner. This slows gravel slurry flow to the screen inner annulus and to the perforations to prevent gravel from bridging the annulus at these locations. The material is removed after the risk of bridging has passed. Various flow-reducing materials, such as wax flakes, salt, clay and gel, may be employed. The method is particularly useful in deviated wells.
