Fracturing Chemicals | Fracturing Fluid

The oil and gas industry has benefited from tremendous growth in production from shale formations. Data from research firm IBISWorld reported that the global oil and gas exploration and production market expanded by an annual rate of 7.5 percent between the years of 2007 and 2014. Evidence suggested this growth would continue into the foreseeable future, particularly in North America, where shale production has enjoyed a significant boom.

Technology is at the heart of this growth. Advanced drilling, completion and well fracture technologies have yielded greater production in some areas and allowed exploration and production firms to tap into resources in regions that were previously assumed to be unyielding. At the same time, fracturing chemicals allow companies to expand the capabilities of advanced technology even further.

Fracturing chemicals are specially engineered to improve frac performance, pushing the latest in oilfield and gas technology to its limits. Chem Rock is an industry leader in the development of best-in-class fracturing chemicals, and our proprietary products deliver top solutions to operators and pressure pump companies working in the oil and gas industry's well fracture area.

Guar viscosity agents and crosslinking agents

Chem Rock offers a range of fracturing chemicals engineered to increase the viscosity of water. Water is crucial to the fracturing process, and it is used in large volumes - sometimes exceeding 200,000 bbls (8.4 million gallons) in the case of horizontal well-fracturing operations. The horizontal or lateral sections are able to expose larger surface area compared to vertical wells. The water used in fracturing is treated with viscosity increasing polymers to ensure the viscosity can evenly support sand proppant.

Guar or guar-based viscosity agents are the most traditionally used viscosity agents used to alter the physical composition of water and achieve the proper level of viscosity. Guar is a common additive - it's frequently used in food and consumer products. Guar is not the only option available for increasing the viscosity in fracturing fluids. Carboxymethyl cellulose (CMC) is also effective and in many ways can be more economical, and it is just one such alternative to guar available to oil & gas operators.

Chem Rock provides a full range of guar products and other guar alternatives, and our commitment to experienced customer support and operational transparency ensures firms that turn to Chem Rock benefit from the cleanest, safest and most environmentally responsible fracturing chemicals.

Fracturing chemicals to reduce friction

High volumes of water are pumped into shale formations at high levels of pressure. In all cases friction can be a considerable challenge to manage. Polymeric friction reducers are used to reduce the hydraulic frictional forces to reduce pressure challenges

Friction reducers are added to fracturing fluids, and these polymeric additives are proven to reduce frictional forces and turbulence during the pumping process. Lower friction losses can also mean less pressure required by the hydraulic power sources.

Chem Rock offers a range of polymeric additives capable of reducing friction up to 70 percent quickly in a range of water conditions including fresh, brackish and salt water

Fracturing fluids to inhibit corrosion and limit the presence of iron

Oil and gas exploration and production firms face other risks during the fracturing process. Hydrochloric acids - often treated at a concentration of 10 to 15 percent - are relied upon to clean shale formation faces during the preparation process, but these acids can also be highly corrosive to pumping equipment. That is why Chem Rock offers acid corrosion inhibitors designed to protect against the threat of corrosion and material failure.

Ferros and ferric iron - often dissolved in the water used in pumping - can also form iron precipitates if exposed to certain oxidants, inhibiting frac performance. Chem Rock offers an environmentally friendly iron chelating agent that increases the solubility of iron in water to reduce this risk.
