Abstract
A method for completing a wellbore may include introducing a wellbore fluid into a wellbore, the wellbore fluid having a base fluid; and a solid weighting agent having a d90 of less than 20 microns; where the method may also include contacting the wellbore fluid with a swellable element in the wellbore; and allowing swelling of the swellable element.
Claims20
A method for completing a wellbore, comprising:
- introducing a wellbore fluid into a wellbore, the wellbore fluid comprising:
- a base fluid;
- and
- a solid weighting agent having a d90 of less than 20 microns;
- contacting the wellbore fluid with a swellable element in the wellbore;
- and
- allowing swelling of the meltable element.
The method of claim 4, wherein the dissolved salts are selected from a group consisting of NaCl, CaCl2, NaBr, CaBr2, ZnBr2, NaHCO2, KHCO2, KCl, NH4Cl, CsHCO2, MgCl2, MgBr2, KH3C2O2, KBr, NaH3C2O2, and combinations thereof.
A method of activating a swellable element, comprising:
- introducing a wellbore fluid into a wellbore through a subterranean formation, the wellbore fluid comprising:
- an aqueous continuous phase having no more than 10 w/w % dissolved salt content therein;
- and
- a solid weighting agent having a d90 of less than 20 microns;
- contacting, the wellbore fluid with a swellable element in the wellbore;
- and
- allowing swelling of the swellable element.
