摘要:
A new multi-purpose foaming composition having applications in oil field application, industrial applications, waste management applications, or other applications that can be benefitted by a foam, is disclosed, where the composition includes a surfactant, a sulfur scavenger and optionally an additive, where the sulfur scavenger and/or additive improve foam characteristics and/or the foam improves an activity of the sulfur scavenger and/or the additives. Method for using and making the foaming compositions are also disclosed, especially, coiled and capillary coiled tubing downhole applications.
摘要:
An under-balanced drilling fluid additive is disclosed which reduces reactive shale and/or clay swelling during under-balanced drilling operations, where the additive includes an effective amount of a choline salt. A method for under-balanced drilling is also disclosed including the step of circulating a drilling fluid including an effective amount of a choline salt to reduce reactive shale and/or clay swelling during under-balanced drilling operations.
摘要:
A hydrocarbon drilling fluid system is disclosed including a hydrocarbon fluid and a foaming composition, where the foaming composition includes a polymer, a gelling agent and its cross-linking agent, an optional foaming agent, or mixtures or combinations thereof. Uses of this drilling fluid system in a variety of downhole application are also disclosed.
摘要:
A method for treating solid materials is disclosed, where the treating compositions coats surfaces or portions of surfaces of the solid materials changing an aggregation or agglomeration propensity of the materials. Treated solid materials are also disclosed. The methods and treated materials are ideally suited for oil field applications.
摘要:
A corrosion control system is disclosed including an anionic oxygen inhibitor, a cationic acid inhibitor or dispersant, and a noxious species inhibitor or scavenger for use in a fluid in contact with a metallic surface at low temperature, moderate temperature and especially at high temperature. A drilling fluid, a completion fluid, a production fluid and a geothermal fluid including an effective amount of the corrosion control system is also disclosed as well as methods for making and using same.
摘要:
An new class of oil-soluble, sulfur scavengers or converts are disclosed where the scavengers include substantially monomeric aldehyde-amine adducts from the reaction of at least one sterically hindered primary or secondary amine and a molar excess of at least one aldehyde. Methods are also disclosed for reducing, reducing below a given level or eliminating noxious sulfur species from fluids using the inventive scavengers and for making the inventive scavengers.
摘要:
A new general purpose foaming agent having application as drilling fluid foaming agents or as any foaming agent needed an a wide variety of applications is disclosed, where the agent includes at least one anionic surfactant, at least one cationic surfactant, and mixtures thereof and one or more zwitterionic compounds. A method for using the foaming agent in capillary coiled tubing application is also disclosed. The foaming agents can also include additive to augment the properties of the foaming agent for a given application.
摘要:
1,3,5 (2H2,4H2,6H2) tripropanediamine N,N,N′,N′,N″,N″ hexamethyl is used to scavenge sulfur compounds from hydrocarbons. A novel method of making the triazine comprises autocondensing (CH3)2N CHCH2CH2N═CH2.
摘要:
Compounds of the formula H(CH2)zCOO—[C2H4O]xCyH2y+1 where z is 0-2, x is an integer from 1 to 5 and y is an integer from 4-9 are used as emulsion breakers and defoamers in formation treatment fluids in the recovery of hydrocarbons from subterranean formations. A preferred material has the formula HCOO—[C2H4O]3C6H7.
