    摘要: A well treating composition of a composite containing a scale inhibitor adsorbed onto a water-insoluble adsorbent is useful in the control, formation and treatment of inorganic scales in a subterranean formation or wellbore. In addition, the well treating composition is useful in controlling the rate of release of scale inhibitor in the wellbore. The water-insoluble adsorbent may be activated carbon, silica particulate, precipitated silica, zeolite, diatomaceous earth, ground walnut shells, fuller's earth and organic synthetic high molecular weight water-insoluble adsorbents. The composite may be introduced into an oil or gas well with a carrier fluid.

    摘要: Disclosed herein is a method of treating a subterranean formation utilizing a fluid having a splittable foamer, i.e., a fluid that creates a stable foam when it contacts the formation but that loses its ability to foam as it remains in contact with the formation for extended time. The present method has the advantage that the fluid can be recovered from the well unhindered by the difficulties involved with recovering a foamed fluid from a well. The present method does not require the use of breakers, though the splitting of the foam can be accelerated by introducing an organic or inorganic acid into the well, if so desired.

    摘要: A non-aqueous well treatment fluid is provided containing a glycol-soluble polymer such as highly substituted hydroxypropyl guar in an alkylene glycol or alkylene glycol ether solvent. A non-aqueous slurry composition for use in preparing water-based well treatment fluids is also provided, having a glycol-soluble polymer such as highly substituted hydroxypropyl guar in an alkylene glycol or alkylene glycol ether solvent. A method is provided for utilizing such a slurry to prepare a water-based well treatment fluid, the method including loading a water-soluble polymer into the slurry, then metering the loaded slurry into water.

    摘要: A formation treating fluid comprises one or more borate esters, a liquid carrier and, one or more cross linkable polymer wherein the formation treating fluid has an alkaline pH when the formation treating fluid is positioned in a formation. The formation treating fluid is useful in high temperature operations such as hydraulic fracturing.
