Residual oil saturation is determined by injecting water containing dissolved CO. sub. 2 and subsequently active base generating reactant into an oil and water containing reservoir and chromatographically analyzing the patterns of the concentrations of in situ reaction-depleted CO. sub. 2 and reaction-increased bicarbonate salt in fluid produced from the reservoir.
Determining Residual Oil Saturation By Injecting Salts Of Carbonic And Halocarboxylic Acids
Residual oil saturation is determined by injecting water containing or contacting dissolved halocarboxylic acid salt and carbonate salt into an oil and water containing reservoir and chromatographically analyzing the patterns of the concentrations of in situ generated CO. sub. 2 and water soluble acid salt in fluid produced from the reservoir.
Dissolving Siliceous Materials With Self-Acidifying Liquid
Charles C. Templeton - Houston TX Evan H. Street - Houston TX Edwin A. Richardson - Houston TX
Assignee:
Shell Oil Company - Houston TX
International Classification:
E21B 4327
US Classification:
252 855C
Abstract:
Siliceous materials in or around a well are dissolved by contacting them with a self-acidifying aqueous liquid system comprising an aqueous solution of at least one water-soluble fluoride salt mixed with a relatively slowly-reactive acid-yielding material that subsequently converts the salt solution to a hydrofluoric acid solution that has a relatively high pH but is capable of dissolving siliceous material.
Well Treating Process For Chemically Heating And Modifying A Subterranean Reservoir
Edwin A. Richardson - Houston TX Walter B. Fair - Slidell LA
Assignee:
Shell Oil Company - Houston TX
International Classification:
E21B 4322 E21B 4324 E21B 4700
US Classification:
166250
Abstract:
A portion of a subterranean oil and water-containing reservoir is concurrently chemically heated and selectively increased in its effective permeability to oil by injecting a solution of compounds containing ammonium ions and nitrite ions, which react exothermically to generate gaseous nitrogen, and a reaction-rate-controlling buffer. The reactant concentration and the rate at which the solution is injected are arranged to provide a selected temperature increase within a selected portion of the reservoir.

International Classification:
G01M 304
US Classification:
73 407
Abstract:
A method is provided for troubleshooting gas-lift wells, to identify whether gas-lift valves on the production tubing are open or closed, without the use of wireline tools. The method may also be used to detect leaks in the production tubing or in the well casing. A quantity of a tracer gas is injected into the lift-gas at the wellhead, and its return in fluid produced from the well is monitored as a function of time. The tracer's return pattern may be correlated with the depth of entry points and volumes of lift-gas entering along the length of the production tubing.

International Classification:
E21B 3700 E21B 4325
US Classification:
166300
Abstract:
Fluid passageways between a well borehole and a subterranean reservoir which are both plugged and submerged within relatively dense brine can be contacted with heat and oil solvent by arranging a nitrogen gas generating aqueous solution to be both reactive at the reservoir temperature and denser than the brine in the borehole and flowing alternating slugs of it and a liquid oil solvent into the zone to be treated.
Method Of Pretreating An Underground Formation For Silicon Polyhalide Consolidation
David R. Davies - Rijswijk, NL Edwin A. Richardson - Houston TX Marinus Van Zanten - Rijswijk, NL
Assignee:
Shell Oil Company - Houston TX
International Classification:
E21B 33138
US Classification:
166281
Abstract:
The formation is consolidated by means of a silicon halide compound that reacts with water present on the walls of the formation pore space thereby forming silicon dioxide that bonds the formation grains together. The bonding strength is increased by a pretreatment of the formation grains with an acid in liquid or gaseous form.
Chemical Process For Backsurging Fluid Through Well Casing Perforations
Edwin A. Richardson - Houston TX Ronald F. Scheuerman - Bellaire TX David C. Berkshire - Houston TX
Assignee:
Shell Oil Company - Houston TX
International Classification:
E21B 2100
US Classification:
166300
Abstract:
A backsurge of fluid through perforations in a well casing is chemically induced by injecting into the surrounding reservoir a solution which contains (a) nitrogen gas-generating reactants, (b) a reaction-retarding alkaline buffer, and (c) a pH-reducing reactant that is capable of subsequently overriding the buffer, so that a rapid production of gas and heat causes a backsurging of fluid into the wellbore.
