                                     Amine is often used to sweeten (remove H2S from) natural gas in a gas plant. "Foam
                                     outs" can disrupt the effectiveness of the amine sweetening process and are an "upset
amine                                condition". Particulate contamination can stablize foam and contribute to foam outs.
                                     This is one of many reaons why amine is filtered. Many gas plants use string wound

                                     Biocides are chemicals added to fracking fluids to kill bacteria and other micro-
                                     organisms. When the fracking fluids are pumped down hole, organisms can multiply,
                                     blocking the formations. The metabolism of some micro organisms can also produce
                                     corrosive byproducts such as H2S (acid gas) that damage metallic equipment and even
                                     concrete. Some bacteria can also metabolize methane gas, causing loss of production.
biocide
                                     Biocides are a source of environmental and health concern, especially because there is a
                                     perceived or actual risk that biocides can get into drinking water supplies (aquifers), and
                                     consequently there is a lot of research into safer biocides and biocide alternatives. In
                                     the USA, the selected biocides must be EPA registered, but drilling companies often
                                     don't have to disclose to the public the names of the biocides they are using.

                                     oil and gas production. See also See "SWD". The most common fluid injected into a class

                                     The process of making a well ready for production (or injection) is called completion.

                                     stimulating and sometimes running in and cementing a casing.

                                     Completion fluids are often brines. They are typically filtered to a high degree to avoid
                                     introducing solids to the near-wellbore area. The fluid is placed in the well in order to
                                     facilitate final operations prior to initiation of production, such as setting screens,
                                     production liners, packers, downhole valves or shooting perforations into the producing

                                     In cross flow filtration (synonymous with tangential flow filtration), some percentage
                                     (but less than 100%) of flow goes through a filtration membrane and is thus filtered,
                                     and the balance flows across the surface of the membrane, helping to keep the
                                     membrane surface clean. The part of the flow that flows through the filter membrane is
                                     called the filtrate or permeate, while the part of the flow that does not flow through the
                                     membrane (but flows across the membrane) is called the retentate or concentrate.
cross flow filtration
                                     Cross flow filtration can be used to filter out particulates, for separations of immiscible
                                     fluids, for removal of molecular contamination, for the removal of salts, and for other
                                     applications as well.The type of contaminant or molecule that can removed (or
                                     retained) by the cross flow filtration system depends primarily upon the type of
                                     membrane that is selected. String wound filters from Delta Pure Filtration are often
                                     used as "pre-filters" in front of cross flow filtration membranes.

                                     Drilling fluid is pumped down into the well throug the drill string while the well bore is
                                     being drilled. The drill string is a long tube tube that goes down into the well with a drill
                                     bit at the very end. The drill string turns the bit, so the bit can chew up the rock. The
                                     drill string is a hollow pipe or tube. The path of the drilling fluid is down the center of
                                     the string, and then up through the bore in space between the drill string and the
                                     formations, called the annulus. This "down the string, up the annulus" flow pattern is
drilling fluid                       often called a u-tube. The drilling fluids lubricate and cool the bit. The drilling fluids also   http://en.wikipedia.org/wiki/Drilling_fluid
                                     carry rock cutting debris up to the surface. If the drilling fluid is not heavy (dense)
                                     enough, fluids in the formation can push out into the bore, so the drilling fluids also
                                     serve to maintain a sufficient hydrostatic pressure. The drilling fluids contain thickner
                                     chemicals and particles, a mixture called mud. The mud lines the bore to protect the
                                     formations and to prevent fluid loss, which is leakage of drilling fluid into the
                                     formations.
                                     Drilling muds are either water or oil based, and contain particles made of calcium
                                     carbonate or barite. The purposes of the mud are to: cool and lubricate the drill bit,
                                     prevent the escape of gas and oil during drilling,

                                     Horizontal drilling is a type of direction drilling. In horizontal wells, the well is drilled
                                     vertically for a stretch, until the "kick off point" (KOP) is reached. At the kick off point,
                                     the direction of the drilling will begin to deviate from vertical, until a horizontal

                                     Liquid liquid coalescers are a type of filter assembly that remove one immiscible liquid
                                     from another, for example, to remove oil droplets from produced water. The method
                                     of separation is coalescence (rather than common alternatives such as adsorption,
                                     physical exclusion, or cyclonic action) whereby tiny droplets of the contaminating fluid
                                     are agglomerated into larger droplets as liquid flows throught the filter medium. The
                                     droplets then either float or sink after they emerge enlarged from the filter cartridge.
                                     Coalescence is enabled when the interfacial surfce tension is sufficiently high, and
