fluid-friction reducer - Schlumberger Oilfield Glossary
A chemical additive that alters fluid rheological properties to reduce friction created within the fluid as it flows through small-diameter tubulars or similar restrictions. Generally polymers, or similar friction reducing agents, add viscosity to the fluid, which reduces the turbulence induced as the fluid flows. Reductions in fluid friction of 50 to 60% are possible.
Friction Reducers | Innospec Oilfield
Friction reducers are intended to reduce the friction in the wellbore during the drilling and stimulation processes in unconventional reservoirs such as coal beds and shales. The large volumes of water pumped, and high rates required, result in high friction pressures from turbulent fluid flow. Cationic or anionic friction reducers reduce
Drilling Mud Additives — Dover Chemical Corporation
Rotary Drilling and Coiled Tubing Lubricants. These products are Sulfurized fatty compounds and hydrocarbons, and are popular lubricant additives manufactured by Dover Chemical Corporation. They reduce torque/friction by 40-50% in both conventional rotary and coiled-tubing (CT) drillings at 1% usage level in water-based mud or CT formula.
SNF Oil and Gas Extraction | SNF Holding Company
PowderFrac is a unique, mobile, self-contained, and automated Friction Reducer (FR) hydrating and dosing system designed to rapidly hydrate dry friction reducers. It offers enhanced performance and cost-savings for a product/system having a greener footprint compared to traditional liquid, emulsion friction reducers.
Filtration Reducers | Schlumberger
Complete line of chemicals used to reduce fluid loss to the formation caused by the liquid phase of the drilling fluid. Water-based-mud fluid loss control additive. Reduce fluid loss in freshwater and seawater muds. Premium-grade resinated lignite. Filtration agent and rheology-stabilizing additive for water-based drilling fluids. Hide
Drispac (Plus) is a high molecular weight, polyanionic cellulose polymer of high purity. It is available in Regular and Superlo grades. Drispac (Plus) is a primary fluid-loss reducer for water-based drilling fluids. Drispac (Plus) Regular also provides secondary viscosity. When fluid loss control…
Oilfield Drilling Fluid Loss Additives | DX Oilfield
DX-Causticized Lignite is a product from North Dakota, used effectively as a mud thinning agent in high-pressure, high-temperature deep well drilling. Processed to be used effectively in both high and low pH systems. It is also a fast reacting, free flowing agent, which reduces fluid loss and gel strength.
DF - Drilling Fluid Products
a viscosiﬁ er, friction reducer, ﬂ occulant and provides some ﬂ uid loss control. It is also formulated for easy mixing and is extremely beneﬁ cial for core drilling applications where good mixing equipment is not available. CORE Warrior dry is a high molecular-weight polymer designed for cuttings encapsulation and shale stabilization
It can also be used for fluid clarification when added at the centrifuge in sumpless drilling operations. Alcomer 758 / Zetag 7587 should be added through a chemical barrel at the flow line or injected directly into a centrifuge from a premixed polymer tank, usually in a 0.5% stock solution.
FUNCTION OF ADDITIVES IN THE DRILLING FLUIDS
These Chemicals modify viscosity and the Relationship Between Percentage of solids in a drilling mud. They May Be Used, further, to reduce gel strength, Increase the fluid’s «pumpability,» etc. Tannins (quebracho), Various polyphosphates, lignite and lignosulfonate materials function as thinners, or as dispersants.
DRILLING FLUID FORMULATION USING CELLULOSE GENERATED FROM
groundnut husk can significantly reduce fluid loss control agent. Hence, the polymer can be used as fluid loss control agent in the mud system. The water loss analysis showed that the drilling fluid formulated from groundnut husk cellulose of 2.0g has a high fluid loss of 7.6mls with a maximum percentage deviation of 13.2%
