摘要:
A method of treating a subterranean formation penetrated by a wellbore is carried out by forming a treatment fluid comprising an aqueous carrier fluid and a solid-form polyimide homopolymer or copolymer capable of hydrolyzing to form polycarboxylates and/or polycarboxylic acids. The treatment fluid is introduced into the formation through the wellbore. In another method, a treatment fluid comprising an aqueous carrier fluid, a solid-form polysuccinimide homopolymer or copolymer and at least one of a viscosifying agent, proppant and an acid capable of dissolving materials of the formation is formed. This is introduced into the formation through the wellbore. A method of treating a sandstone-containing formation penetrated by a wellbore may also be carried out by forming a treatment fluid comprising an aqueous solution containing a hydrogen fluoride source, ammonium hydroxide and at least one of a polyimide and a polycarboxylate, which is introduced into the formation through the wellbore.

摘要:
A technique includes completing a well, including installing a tubing string that includes a screen in the well and installing a fiber-based material outside of the screen. The technique further includes using the well as an injection well, including communicating a fluid into the tubing string to cause an injection flow to be communicated in a fluid flow path from an interior of the tubing string, through the screen and into a formation.
摘要:
In a method of treating a sandstone-containing formation penetrated by a wellbore, a treatment fluid comprising an aqueous fluid containing a Bronsted acid, a hydrogen fluoride source and an organic acid or salt thereof that is substantially soluble in the aqueous fluid is formed. The treatment fluid contains less than about 2% of fluoride (F−) by weight of the fluid and from 2% or less of sodium (Na+) by weight of the fluid. The treatment fluid is introduced into the formation through the wellbore as a single-stage without introducing an acid-containing fluid preflush into the formation prior to introducing the treatment fluid.

摘要:
Acidizing methods for subterranean formations formed of predominantly siliceous material as well as acidizing compositions. Some methods include injecting into a predominantly siliceous subterranean formation, an aqueous acidic mixture formed by blending an aqueous liquid, a fluoride source, and an effective amount of an alkane sulfonic acid, preferably methane sulfonic acid, to adjust the pH of the fluid where the alkane sulfonic acid where the alkane group may be an unbranched, a branched or a cyclic alkyl residue. Hydrofluoric acid (HF) may not be added to the fluid in some embodiments as the fluoride source, such as the case for an HF free fluid, and, in some instances, hydrochloric acid is not added to the fluid to adjust pH. Also described are compositions containing an aqueous acidic mixture formed by blending an aqueous liquid, a fluoride source, and an effective amount of an alkane sulfonic acid to adjust pH.

A system and method of providing streaming audio and video data to multiple users is described. In one embodiment, the system comprises a first client, a second client and a server. The first and second clients are executing browsers. The server can communicate with the two clients. The server concurrently provides streaming audio and video data to both of the clients. Importantly, the server does not require the two browsers to use a plug-in or a helper application to receive and use the streaming audio and video data.
