Definitions

  • the present disclosure relates generally to compositions and methods for treating or completing a subterranean well having a borehole. More particularly, the disclosure relates to cement slurry compositions for cementing a subterranean well and, in the alternative, methods for subterranean well completions and/or cementing a subterranean well having a borehole. The present disclosure also relates to cement-slurry compositions and methods for preparing cement slurry compositions having hydrophobic polymer particles as additives.
  • a cement slurry is prepared at the surface and then pumped into the subterranean well through a liner or casing to fill the annulus between the casing and borehole wall. Once the slurry sets, the cement may provide a number of functions, including providing zonal isolation and segregation, corrosion control, and structural support. A properly prepared slurry and set cement form a strong, nearly impermeable seal around the casing.
  • the cement slurry should have relatively low viscosity to facilitate pumping and maintain effectively constant rheological properties during both preparation at the surface and delivery into the well and the target zone. Assuming the cement slurry is properly prepared and delivered to the target zone, the properties of the set cement will depend primarily on the components of the slurry and the additives included in the slurry composition. Ideally, the properly placed cement will develop high compressive strength in a minimum of time.
  • organic polymeric particles have been employed as additives in the cement slurry to achieve or enhance certain cement properties.
  • the addition of the polymeric particles leads to improved joining of the slurry constituents, which may help achieve improved strength and durability characteristics, among other things.
  • the hydrophobic character of the particles may, however, also present some undesirable issues.
  • mixability and foaming problems may be observed in the polymer-modified cement slurry.
  • cement slurries are often prepared using the continuous mixing method, also known as mixing on-the-fly. Solid blends are mixed with water and liquid additives by using a jet mixer.
  • the jet mixer generates a regulated flow of solids that creates a void to draw a dry powder component (due to a venturi effect) into the mix.
  • the drawing action also draws and entrains air in the slurry. If allowed to stabilize, excess air in the slurry can lead to densely packed air bubbles collecting and then forming at the slurry surface, i.e., foaming. Excessive entrained air and foam can adversely affect the slurry design. For example, it can alter the slurry composition and performance, including deviating from optimal slurry density or increasing slurry viscosity. Such conditions may also cause pumping problems and inefficiencies.
  • Antifoam and defoamer additives may be added to the slurry to prevent or minimize foaming.
  • Separator equipment may also be used in conjunction with traditional slurry mixers to mechanically remove the entrained air from the slurry.
  • the SlurryAirSeparator device from Schlumberger Ltd. employs a hydrocyclone mechanism to separate and remove entrained air from the cement slurry.
  • the slurry may be transferred to a large tank for batch mixing. Much of the remaining entrained air may be removed from the slurry.
  • any of the aforementioned options may be effective in reducing entrained air and foam in the slurry, the employment of these options may not be feasible. For example, operating time and cost associated with using additional equipment or additives may not be acceptable, or the equipment may not be readily available in some field locations. Also, some of these measures have proven less than satisfactory in reducing entrained air and foam under certain operating conditions.
  • the present disclosure is directed to cement slurry compositions having hydrophobic particles.
  • Embodiments relate to methods for improving the mixability of cement slurries comprising hydrophobic particles. Further embodiments relate to methods for cementing or completing subterranean wells comprising a borehole.
