Definitions
- compositions and methods for treating subterranean formations in particular, compositions and methods for cementing and completing wells into which carbon dioxide is injected, stored or extracted.
- the tubular body may comprise drillpipe, casing, liner, coiled tubing or combinations thereof.
- the purpose of the tubular body is to act as a conduit through which desirable fluids from the well may travel and be collected.
- the tubular body is normally secured in the well by a cement sheath.
- the cement sheath provides mechanical support and hydraulic isolation between the zones or layers that the well penetrates. The latter function is important because it prevents hydraulic communication between zones that may result in contamination. For example, the cement sheath blocks fluids from oil or gas zones from entering the water table and polluting drinking water.
- the cement sheath achieves hydraulic isolation because of its low permeability.
- intimate bonding between the cement sheath and both the tubular body and borehole is necessary to prevent leaks.
- the cement sheath can deteriorate and become permeable.
- the bonding between the cement sheath and the tubular body or borehole may become compromised.
- the principal causes of deterioration and debonding include physical stresses associated with tectonic movements, temperature changes, pressure changes inside the casing and chemical deterioration of the cement.
- Oil and gas that contains elevated amounts of hydrogen sulfide are called "sour.” It has been estimated that 15 to 25% of natural gas in the United States may contain hydrogen sulfide. Worldwide, the percentage could be as high as 30%. Hydrogen sulfide is a toxic substance; therefore, it is important to prevent it from escaping through the cement sheath into aquifers or to the surface. Furthermore, hydrogen sulfide is corrosive to steel, and maintaining a competent cement sheath is essential to prevent casing deterioration during the life of the well.
- compositions that form a sustainable cement sheath even in a hydrogen-sulfide environment and methods by which they may be prepared and applied in subterranean wells.
- embodiments relate to methods for maintaining zonal isolation in a subterranean well having a borehole in which hydrogen sulfide is present.
- a tubular body is installed inside the borehole of a well, or inside a previously installed tubular body.
- An aqueous cement slurry, containing a material that swells when contacted by hydrogen sulfide, is pumped into the borehole.
- the cement slurry is allowed to set and harden.
- the set cement is exposed to wellbore fluids that contain hydrogen sulfide.
- the material is allowed to swell, thereby restoring zonal isolation.

- the cement slurry is allowed to set and harden.
- the set cement is exposed to wellbore fluids that contain hydrogen sulfide.
- the material is allowed to swell, thereby restoring zonal isolation.
- a concentration range listed or described as being useful, suitable, or the like is intended that any and every concentration within the range, including the end points, is to be considered as having been stated.
- a range of from 1 to 10 is to be read as indicating each and every possible number along the continuum between about 1 and about 10.
- cement systems that form durable cement sheath in an environment containing hydrogen sulfide would be positively received by the industry.
- the Applicant has determined that cement compositions comprising materials that swell in the presence of hydrogen sulfide would respond to the industry challenges.

- elastomers may fulfill the required swellable capacity in the presence of hydrogen sulfide.
- elastomers comprise fluorinated elastomers, ethylene -propylene copolymers and combinations thereof.
- embodiments relate to methods for maintaining zonal isolation in a subterranean well having a borehole, in which hydrogen sulfide is present.

- Other example fluorinated elastomers may comprise perfluoroelastomers, which are given the designation FFKM in the elastomer industry.
