摘要： A resin composition useful in well completion and remedial methods having improved flexibility upon setting or curing is disclosed. The resin composition includes a polymerizable resin, an oil soluble acid catalyst capable of causing polymerization of the resin at formation temperatures, and 10 to 70% by volume rubber. The rubber may be in the form of ground rubber or an aqueous dispersion or emulsion. Also disclosed are methods for the use of the resin composition in well completion and remediation.

摘要： An improved method to detect water influx using video monitoring of a cased wellbore is disclosed. A wireline well tool having a video camera and a light source is lowered into a selected borehole interval where water influx is suspected. The borehole fluid over the selected interval is displaced and replaced with either a water transparent mixture containing a viscosifying agent, a coloring agent and/or sufficient salt to increase mixture density; or a transparent water insoluble solvent. By use of either of these displacement fluids, the quality of video monitoring over the selected borehole interval for water influx, is enhanced.

摘要： This invention relates to methods of treating subterranean formations. An impermeable plug is formed in a section of a cased and perforated borehole by transmitting from the surface a fluid resin comprising a polymerizable polymer and subsequently transmitting from the surface an acid catalyst which causes flash setting of the polymerizable polymer.

摘要： An improved method for acidizing an oil bearing formation in the presence of water bearing zones having high permeability is described. An aqueous fluid is pumped into the formation preceding the injection of stimulation material. This fluid contains hydroxyethylcellulose, a fluorescent dye and an organic acid anhydride, which during hydrolysis reduces the pH and the viscosity of the solution making it retrievable without damage to the formation.

摘要： A method for consolidating unconsolidated mineral particles in a subterranean petroleum formation penetrated by a well in fluid communication with at least a portion of the formation, including: a) introducing an effective amount of preflush into the formation sufficient to invade substantially all of the pore spaces of a portion of the formation to be consolidated, said preflush including an ester, and an oligomer or monomer of the compound from which the resin to be used in the consolidation is obtained, an ester, and an effective amount of a coupling agent; b) introducing a sand consolidating fluid into substantially the same portion of the formation as the preflush fluid, the sand consolidating fluid containing a polymerizable compound, a diluent for the polymerizable compound and an acid catalyst capable of causing condensation polymerization of the compound at fluid injection temperatures; and c) allowing the injected fluid to remain in the formation for a period of time sufficient to accomplish at least partial polymerization of the monomer, forming a permeable consolidated mass around the wellbore.

摘要： Disclosed is an improvement in a method for treating wells penetrating subsurface formations and in fluid communication with at least a portion of the subsurface formation for the purpose of sand consolidation, water exclusion, or well plugging, employing a treating fluid comprising acid catalyzed polymerizable resin, a hydrolyzable ester and an acid catalyst, which improvement provides greater control of set time and greater safety, which comprises replacing from a small percent up to the entire amount of hydrolyzable ester with an acetate derivative of the polymerizable resin, and optionally replacing a small percent up to the entire amount of the polymerizable resin with the acetate derivative. In the preferred embodiment furfuryl acetate replaces part to all of the hydrolyzable ester and, optionally, a percentage of the furfuryl alcohol.
