process, for example friction reducers (see section 3 for further details) . ... It is recovered through the drilling of a series of vertical or horizontal wells directly into the coal seam and then pumping water out to lower the pressure in a process known as 'dewatering'. Reducing the pressure withi n the coal seams allows the methane to flow ...

A method and composition for reducing a coefficient of friction are disclosed. In an embodiment, a method for reducing a coefficient of friction between two surfaces in a borehole includes preparing a mixture comprising a primary lubricating agent, a primary surfactant, a spreading agent, and an aqueous fluid. The method also includes pumping the mixture into the borehole such that the mixture ...
Hydraulic fracturing is water intensive, and operators look to reduce the use of fresh water by recycling the maximum amount of produced water possible. Working closely with a service company and operator, Nalco Champion developed a salt-tolerant, water-based friction reducer that does just that, offering environmental, economic, and operational advantages over previous technology.

representative cohesive coal in contact with a dull and polished mild steel surfaces. It is to be noted that the wall friction angle cannot be larger than the effective angle of internal friction δ which is an upper bound limit for ø. Thus, for very low normal pressures where the friction angle 4
Neo Solutions, Inc. offers a complete line of Freeze Control products, effective from -28°F (-33°C) to -72°F (-58°C), to enable efficient, trouble-free handling and transport of coal and minerals under freezing conditions during the winter season.
However, AMD transfer is likely to be limited by quick microbial degradation. ... (EOR) and more recently as a friction reducer in high volume hydraulic ... sealing, coal dewatering mediators ...
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.
in-house friction flow loop, fluid characterization and rheology testing. Based on these results, we are then able to recommend a product and concentration for your application.

Friction Reducer Application History in Oilfield. The concept of drag reduction was first proprosed in the 1940s. In the early 20th century ...
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.
Apr 18, 2019· What is claimed is: 1. A polymeric friction-reducing composition useful when treating a subterranean formation penetrated by a wellbore that has been stimulated with a brine fracturing fluid having 50,000 ppm total dissolved solids or more and a proppant, said polymeric friction-reducing composition comprising a mixture of polymeric friction reducers comprising (a) a first friction reducer ...

where, K is the K value for a fitting (or for all fittings combined) D is the pipe diameter f is the Fanning friction factor. You can use this equivalent length is used in the above Darcy's equation, to calculate the frictional pressure losses across the pipe run including all the fittings and valves in the path.
Water-soluble polymers that improve water infiltration, reduce crusting and erosion/runoff of soil, fertilizers, and pesticides. ... For coal and iron ore pellitization. Coagulants. ... Friction Reducers.
As friction increases, momentum is reduced during the transfer, requiring more force on the part of the caregiver to perform the task. Friction reducing slider sheets are becoming more widely used in the healthcare setting. When using these sheets, the patient's weight actually feels lighter and moves with less friction and drag.
