摘要: A wellbore treatment fluid comprising: a base fluid; and a water-soluble salt, the salt comprising: a cation; and an anion, wherein the anion is selected from phosphotungstate, silicotungstate, phosphomolybdate, and silicomolybdate. The treatment fluid can have a density greater than or equal to 13 pounds per gallon. A method of treating a portion of a subterranean formation penetrated by a well comprising: introducing the treatment fluid into the well.

摘要: Methods and systems for treating a subterranean formation. An example method performs a wellbore operation with a first treatment fluid, removes a flammable gaseous hydrocarbon from a well penetrating the subterranean formation; wherein the well is disposed on a wellsite, introduces the flammable gaseous hydrocarbon into a gas-to-liquid reactor located on the wellsite to produce an oleaginous liquid, produces a second treatment fluid comprising the oleaginous liquid at the wellsite, and introduces the second treatment fluid into the well.

摘要: A method for modifying a return fluid in a wellbore comprising disposing at least one valve along a drill pipe section of a drill string in the wellbore. At least one parameter of interest is determined at at least one location along the wellbore. At least one valve is controllably actuated to discharge at least a portion of at least one fluid from inside the drill string to an annulus in the wellbore to modify a local property of the return fluid in the annulus based at least in part on the measured parameter of interest.

摘要: A method comprises flowing a mud into a wellbore, wherein the mud has a mud composition and has a weight in a defined range. The method includes introducing a fluid pill into the mud flowing into the wellbore, wherein the fluid pill has an injection fluid with an injection composition that is different from the mud composition. A particulate has been added to the injection fluid to increase the weight of the fluid pill. After flowing the mud into the wellbore such that the fluid pill is positioned in a zone of the wellbore: filtering out the particulate from the injection fluid; injecting, after the filtering, the injection fluid into the zone; measuring a downhole parameter that changes in response to injecting the injection fluid into the zone; and determining a property of the formation of the zone based on the measured downhole parameter.

摘要: An aqueous-based well treatment fluid for and methods of controlling metal ions in a well, wherein the treatment fluid and methods use one or more polymer microgels, which comprise a plurality of polymer particles. Each polymer particle has a polymeric backbone bearing at least one moiety where such moiety is a chelating agent capable of boding with a metal ion.

摘要: Compositions and methods for treating a downhole environment are provided. The method includes introducing a treatment solution containing a cyclic orthoester and brine into a wellbore within the downhole environment and hydrolyzing the cyclic orthoester to produce an acid within the downhole environment.

摘要: A method for monitoring the oleophilic fluid to aqueous fluid ratio of a drilling fluid includes selecting a sample of the drilling fluid that has been recirculated, measuring the NMR response of the sample of the drilling fluid and determining the oleophilic fluid to aqueous fluid ratio of the drilling fluid based at least in part on the NMR response.
