    摘要: A composition for use in a wellbore activity, the composition comprising a stabilized divalent iodide brine, the stabilized divalent iodide brine comprises a divalent salt system, where the divalent salt system comprises a divalent iodide, an primary iodide stabilizer, the primary iodide stabilizer operable to remove free iodine, prevent the formation of free iodine, and suppress TCT, and an aqueous fluid, where the stabilized divalent iodide brine has a density greater than 11 lb/gal, where the stabilized divalent iodide brines has a TCT of less than or equal to 70 deg F.

    摘要: A method of using a suppression factor fluid during a well activity is provided. The method comprising the steps of introducing a suppression factor fluid into a wellbore, the suppression factor fluid comprising an untreated monovalent brine; and a suppression sugar alcohol, the suppression sugar alcohol in an amount operable to achieve a suppression factor, wherein a density upper limitation of the suppression factor fluid is greater than the density upper limitation of the monovalent brine; and completing the well activity in the wellbore, such that the suppression sugar alcohol inhibits crystallization during the well activity.

    摘要: A method for the controlled delivery of a fracturing fluid to a well bore comprises formulating an aqueous base fluid such that it meets or exhibits desired physical and chemical characteristics for an optimal fracturing fluid. The formulation of the aqueous base fluid max involve commingling one or more sources of waste water with a source of fresh water followed by controlled injection of one or more additives. This process is substantially completed prior to delivering the aqueous base fluid to the well site. This allows the delivery of an optimal volume of the aqueous base fluid with homogeneously blended additives to the well bore.

    摘要: Provided is a method and apparatus for pulling a crown plug from a subsea horizontal christmas tree, the method comprising: (a) providing a subsea lubricator having a longitudinal through bore and a jack attached to the subsea lubricator, the jack having a landing area, and the landing area having an opening which is fluidly connected to the lubricator's through bore; (b) providing a jacking string which includes a landing sub and a crown plug connector, the sub having a landing surface; (c) without the jacking string in step “b”, lowering the subsea lubricator of step “a”, to the horizontal christmas tree and attaching the lubricator to the christmas tree; (d) lowering the jacking string to the lubricator, and, while the landing surface of the landing sub is spaced above and not supported by the landing area of the jack, connecting the plug connector to the crown plug while the landing sub is above and not touching the landing area of the jack; (e) jacking up the jack such that the landing area of the jack contacts the landing surface of the landing sub, and pushes up on the jacking sub and jacking string causing tensile forces to be placed on the crown plug and releasing the crown plug from the profile of the christmas tree; (f) while the lubricator remains attached to the christmas tree, raising the jacking string and crown plug through and out of the lubricator and to the surface of the water to remove the tree; and (g) detaching the crown plug from the crown plug connector.
