Abstract
The invention concerns a method of improving characteristics of a set cement in an oil- or gas-well. The method according to the invention comprises adding para-aramid synthetic fibers to a cement slurry; and allowing the cement slurry comprising the para-aramid fibers to set. The characteristic to be improved is the resistance to impact, the resistance to high temperature and pressure variations, and/or the drillability of said set cement uses of para-aramid synthetic fibers to enhance specific mechanical properties of cements in an oil- or gas-well.
Claims20
A method of improving characteristics of a set cement in an oil- or gas-well, the method comprising:
- adding para-aramid synthetic fibers to a cement slurry;
- and
- allowing the cement slurry comprising the para-aramid fibers to set;
- and wherein the improved characteristic is one or more of resistance to impact, resistance to high temperature, resistance to pressure variations, or drillability of said set cement.
A method comprising:
- providing a cement slurry;
- adding para-aramid synthetic fibers to the cement slurry;
- and
- allowing the cement slurry comprising the para-aramid fibers to set;
- wherein one or more of resistance to impact, resistance to high temperature, resistance to pressure variations, or drillability of the set cement are improved.
A method of placing a cement structure in a wellbore, the method comprising:
- providing a cement slurry;
- adding para-aramid synthetic fibers to the cement slurry;
- and
- allowing the cement slurry comprising the para-aramid fibers to set.
