Problems solved by technology

[0002] Also, for example, if a relatively light-weight porous crystalline ceramic (eg, alumina) proppant is used, fluids (eg, fracturing fluids) can penetrate into the proppant, increasing its density, which in turn may affect the proppant inflow pressure. Detrimental effects on cracked areas

example 1

[0271] A 20% by weight aqueous fluoropolymer solution (obtained from 3M Company, St. Paul, MN (Minnesota 3M Company, Sao Paulo)) was diluted to 5% to prepare a 5% by weight treatment solution.

[0272] About 100 grams of medium-strength ceramic proppant (obtained from Carboceramics, Irving, TX (Carbo Ceramics, Inc., Irving, Texas) under the trade designation "CARBOPROP 20 / 40" (20 / 40 mesh)) In a 500 milliliter (ml) flask. At 25°C, approximately 20 grams of the treatment solution was added to the flask containing the proppant. The contents of the flask were heated to about 50°C by a water bath and mixed for about 30 minutes. After mixing, at about 50°C, the mixture was heated under reduced pressure (about 50 mmHg) using a rotary evaporator (obtained from Brinkmann Instruments, Inc (Westbury, NY) (Westbury, NY) under the trade designation "ROTAVAPOR" (type R-124)). ) to remove the liquid medium (ie solvent). The treated proppant was then dried in an oven at about 70°C for abo...

example 2

[0274] The treated proppant of Example 2 was prepared as described in Example 1, except that a 20% by weight aqueous fluoropolymer solution ("3M STAIN RESISTANT ADDITIVE SRC-220" ) was diluted to 5% to prepare a treatment solution. The weight percent of active fluoropolymer added to the proppant was about 1% by weight.

example 3

[0276] The treated proppants of Example 3 were prepared as described in Example 1, except that a 10 wt. 4000)" from 3M Company) was diluted to 5% by weight to prepare the treatment solution. The weight percent of active fluorinated disilane added to the proppant was about 1% by weight.

Abstract

The invention describes particles, including proppants, comprising a fluorinated siloxane. The particles are useful as proppants in fractured a subterranean geological formation comprising hydrocarbons.

Description

Background technique [0001] Oil and gas are extracted from wells in subterranean formations that are porous and permeable. The porosity of a formation allows it to store oil and gas, while the permeability of a formation allows oil or gas fluids to pass through it. The permeability of formations is essential for oil and gas to flow to a location where they can be pumped from wells. Sometimes the permeability of formations containing gas or oil is insufficient for desired oil and gas recovery. In other cases, during well operation, the permeability of the formation decreases to a point where further recovery becomes uneconomical. In such cases, the formation is typically fractured and the fracture propped in an open condition using a proppant material or proppant. Such fracturing processes are usually accomplished hydraulically. Proppant materials or proppants are typically particulate materials such as sand and (man-made) engineered proppants such as resin-coated sand, and...
