Abstract

Mineral particles may provide for wellbore fluids with tailorable properties and capabilities. Methods of using mineral particles may include circulating a wellbore fluid with a first density of about 7 ppg to about 50 ppg in a wellbore penetrating a subterranean formation, the wellbore fluid comprising a base fluid, a plurality of first mineral particles, and a plurality of second mineral particles such that the first mineral particles and the second mineral particles are present in a first relative ratio, and the first mineral particles and the second mineral particles having a multiparticle specific gravity of about 3 to about 20; and changing the first relative ratio to a second relative ratio on-the-fly so as to yield the wellbore fluid with a second density.

First claim

The invention claimed is:

1. A method comprising:
circulating a wellbore fluid with a density of about 7 ppg to about 50 ppg in a wellbore penetrating a subterranean formation, the wellbore fluid comprising a base fluid and a plurality of linkable mineral particles, and the wellbore fluid having first viscosity;
introducing a linking agent into the wellbore fluid in response to a condition encountered in the wellbore during circulating so as to yield a second viscosity that is greater than the first viscosity of the wellbore fluid without forming a non-pumpable fluid; and
recovering the plurality of linkable mineral particles from the wellbore without forming the non-pumpable fluid.

2. The method of claim 1 further comprising:
drilling a wellbore with the wellbore fluid.

3. The method of claim 1 further comprising:
producing hydrocarbons from the subterranean formation.

4. The method of claim 1 further comprising:
recycling the plurality of linkable mineral particles.

5. The method of claim 1 , wherein the linking agent is selected from the group consisting of eugenol, guaiacol, methyl guaiacol, salicyladehyde, salicyladimine, salicylic acid, sodium salicylate, acetyl salicylic acid, methyl salicylic acid, methyl acetylsalicylic acid, anthranilic acid, acetyl anthranilic acid, vanillin, catechol, derivatized phthalic acid, unsubstituted phthalic acid, ortho-phenylenediamine, ortho-aminophenol, ortho-hydroxyphenylacetic acid, and any combination thereof.

6. The method of claim 1 , wherein the linking agent is present at about 0.1% to about 10% by weight of the plurality of linkable mineral particles.
