20140352965 | METHOD AND APPARATUS FOR DOWNHOLE APPLICATION OF TREATMENT CHEMICALS IN GAS WELLS - Improved methods are provided for the application of downhole oil or gas well treating agents, such as liquid corrosion inhibition agents. The methods involve first lowering a liquid retainer device into a well casing, preferably at or above the location of the well production zone, followed by introduction of a liquid treating agent. The presence of the liquid retainer device prevents substantial passage of the agent into the production zone, and forms a column of the liquid agent above the device. The retainer device is then withdrawn from the well so as to create a substantially uniform film of the agent along the inner surfaces of the well casing. In this manner, proper coating of the casing is achieved while preventing production losses owing to passage of the treating agent into the production zone. The liquid retainer is preferably one or more swab cups or oil field retainers. | 12-04-2014 |
20140349015 | CORROSION INHIBITOR SYSTEMS USING ENVIRONMENTALLY FRIENDLY GREEN SOLVENTS - Improved anti-corrosion systems or products are disclosed containing individual epoxy and curing agent fractions dispersed in low VOC ester-containing dispersants. Preferably, the epoxy fraction is a conventional epoxy resin, whereas the curing agent is imidazoline. the dispersant includes a mixture of carboxylic acid esters advantageously including glutarate, succinate, and adipate esters. | 11-27-2014 |
20140346404 | CORROSION INHIBITOR SYSTEMS USING ENVIRONMENTALLY FRIENDLY GREEN SOLVENTS - Improved anti-corrosion systems or products are disclosed containing individual epoxy and curing agent fractions dispersed in low VOC ester-containing dispersants. Preferably, the epoxy fraction is a conventional epoxy resin, whereas the curing agent is an imidazoline. The dispersant advantageously includes a mixture of carboxylic acid esters, such as alkyl glutarate, succinate, and adipate esters. | 11-27-2014 |
20140272423 | ANTI-CORROSION COMPOSITIONS FOR NATURAL GAS RECOVERY OR CONVEYING EQUIPMEN - Improved anti-corrosion systems are provided for use with hydrocarbon recovery, treatment and distribution equipment, in order to inhibit corrosion on the metal surfaces thereof. The systems include an epoxy resin, a curing agent for the resin, and a surfactant, which is the reaction product of an alkyl benzene sulfonic acid at least partially neutralized of from about 6-11 with an ammonia or amine neutralizing agent. The systems provide improved anti-corrosion protection in the case of metal surfaces not continually wetted with liquid hydrocarbons, such as crude oil. | 09-18-2014 |
