Abstract

Application of lecithin-based oil compositions to additive particles to control dusting. Without limitation, a method of reducing an amount of dust produced during transfer of additive particles in well operations may comprise providing treated additive particles comprising additive particles and a lecithin based oil composition disposed on a surface of at least portion of the particles. The lecithin -based oil composition may comprise a lecithin and an organic solvent. The method may further comprise mixing components comprising the treated additive particles and a base fluid to provide a treatment fluid. The method may further comprise introducing the treatment fluid into a subterranean formation.

First claim

What is claimed is:

1. A method of reducing an amount of dust produced during transfer of additive particles in well operations, comprising:
transferring the additive particles from a transport trailer, through a transfer tube, to a storage container;
treating at least some of the additive particles with a lecithin-based oil composition during the step of transporting the additive particles from a transport trailer, wherein the lecithin-based oil composition comprises lecithin and an organic solvent selected from the group consisting of a polyalphaolefin, a diester, a polyalkylene glycol, and a combination thereof;
storing the additive particles;
transferring the additive particles after storage, wherein the lecithin-based oil composition reduces the amount of dust produced during the step of transferring the additive particles after storage;
mixing components comprising the treated additive particles and a base fluid to provide a treatment fluid; and
introducing the treatment fluid into a subterranean formation.

2. The method of claim 1 , wherein the step of treating the additive particles with the lecithin-based oil composition comprises at least partially coating the at least some of the additive particles with the lecithin-based oil composition.

3. The method of claim 2 , further comprising transferring the treated additive particles to one or more mixing apparatuses.

4. The method of claim 1 , wherein the additive particles are bulk particles, mesoscopic particles nanoparticles, or combinations thereof.

5. The method of claim 1 , wherein the additive particles comprise at least one material selected from the group consisting of sand; bauxite; ceramic material; glass material; resin precoated sands; resin precoated proppants; polymer material; polytetrafluoroethylene material; nut shell pieces; seed shell pieces; cured resinous particulate comprising nut shell pieces; cured resinous particulate comprising seed shell pieces; fruit pit pieces; cured resinous particulate comprising fruit pit pieces; wood; composite particulates; and combinations thereof.

6. The method of claim 1 , further comprising introducing the treatment fluid into the subterranean formation at or above a fracturing pressure, wherein the treated additive particles are deposited into a fracture in the subterranean formation to hold open the fracture.

7. The method of claim 6 , wherein the additive particles comprise sand.

8. The method of claim 1 , wherein the lecithin is derived from soybean oil, eggs, milk, marine sources, rapeseed oil, cotton seed oil, sunflower oil, and any combination thereof.

9. The method of claim 1 , wherein the lecithin is a commercial lecithin comprising a phospholipid and an oil.

10. The method of claim 1 , wherein the lecithin-based oil composition is present in the treated additive particles in a concentration of about 0.01% v/w to about 5% v/w.
