    Abstract: Thermal recovery wells, geothermal wells and deep hot wells may involve the application of heat to the cement sheath and well casing at some time after the cement has set. Such heating may subject the cement sheath to mechanical burdens that may lead to failure. Such burdens may be lessened if the linear thermal coefficient of expansion is variable and approximates that of the well casing. A variable linear thermal coefficient of expansion may be achieved by incorporating blast furnace slag, silica fume, fly ash or a combination thereof in the cement blend.

    Abstract: A method of and apparatus for treating a zone in a well is disclosed. A tube that is permeable to a material is inserted into a wellbore, creating an annulus inside the wellbore. Two zones—the annular region and the formation surrounding the wellbore—may be treated. The method comprises the following steps. (1) A setting section surrounded by a sleeve is placed inside the tube near the zone to treat, the sleeve being expandable and impermeable to the material. (2) The sleeve is inflated inside the tube near the zone to treat, ensuring that a first zone of the tube is impermeable to the material, but leaving a second zone permeable to the material. (3) A treatment fluid is pumped to the zone to treat, the treatment fluid passing into the annulus via the second zone. (4) The zone to treat is treated with the treatment fluid.

    Abstract: Cement compositions comprising an inorganic cement, water, polymer particles and a water immiscible fluid are useful for reducing the torque necessary to rotate casing during a cementing operation. Such casing movement promotes efficient removal of drilling fluid from the annulus between the casing and the formation or the casing and another casing string. The compositions are particularly useful for cementing operations involving deviated and horizontal wells.

    Abstract: Systems and methods for determining annular fill material using resistivity measurements are provided. In one example, a method is provided. The method may include placing a downhole tool into a cased well. The well may include an annulus located between a casing and a formation. The method may also include determining, by the downhole tool, resistivity measurements associated with portions of the well. Furthermore, the method may include identifying, by a computer, based at least in part on the resistivity measurements, the presence of annular fill materials in the well. Additionally, the method may include determining, by the computer based at least in part on the resistivity measurements, respective locations of the annular fill materials in the well.
