The VESM contains an amphoteric surfactant, an arylalkyl sulfonate cosurfactant and a polar solvent. The VESM may be employed as part of systems used in fracturing, acidizing, gravel ... 04/06/06 - 20060073986 - Method of removing an invert emulsion filter cake after the drilling process using a single phase microemulsion Single phase microemulsions improve the removal of filter cakes formed during drilling with invert emulsions. The single phase microemulsion removes oil and solids from the deposited filter cake. Optionally, an acid capable of solubilizing the filter cake bridging particles may also be used with the microemulsion. In one non-limiting embodiment ... 04/06/06 - 20060073985 - Shale hydration inhibition agent and method of use A method of using a water-base wellbore fluid in subterranean wells that penetrate through a subterranean formation containing a shale which swells in the presence of water. The well bore fluid includes, an aqueous based continuous phase, and a shale hydration inhibition agent. One illustrative shale hydration inhibition agent is ... 04/06/06 - 20060073984 - Shale hydration inhibition agent and method of use A water-base wellbore fluid for use in subterranean wells that penetrate through a subterranean formation containing a shale which swells in the presence of water. The well bore fluid includes, an aqueous based continuous phase, and a shale hydration inhibition agent. One illustrative shale hydration inhibition agent is preferably the ... 04/06/06 - 20060073983 - Shale hydration inhibition agent and method of use A water-base wellbore fluid for use in subterranean wells that penetrate through a subterranean formation containing a shale which swells in the presence of water. The well bore fluid includes, an aqueous based continuous phase, and a shale hydration inhibition agent. One illustrative shale hydration inhibition agent is preferably the ... 04/06/06 - 20060073982 - Shale hydration inhibition agent and method of use in which R and R′ independently selected from hydrogen, methyl, ethyl or propyl, and X has a value from 1 to 6. The shale hydration inhibition agent is present in sufficient concentration to substantially reduce the swelling of shale drilling cuttings upon contact with the drilling fluid. The drilling fluid ... ### FreshPatents.com Support |
