Circulation of completion, workover and drilling fluids used in hydrocarbon recovery filter, after inspection, the viscosity, which often leads to connect the filters. Viscometer generating a signal representative of fluid viscosity, the signal is a programmable controller is used to direct viscous fluid from the filter, or take other steps to prevent damage to the filter. Viscometer can be used in various positions on the system. Considered to be too viscous fluid viscosity reduces the filter device, which can be can be sent to the heating, shear-thinning and enlargement of a device to reduce the viscosity of the liquid through the filter without fouling. After filtration and return to a lower temperature, the liquid can be treated, if necessary, to become viscous useful. Temperature monitor can be deployed in liquid countries whose economies are still emerging, or downstream from the enlargement or other device to help the various fluid viscosity temperature correlations. Cavitation device can also be used to increase the dilute polymer containing viscous fluid concentrations of useful value
Oil and gas production from the land, drilling and completion fluids typically recirculated through the filter. Clean the completion of drilling fluids and the benefits are well known. The most common method of filtration of completion fluids and drilling was diatomaceous earth (sometimes briefly "DE) filters and cartridge filters. In any case, conventional filters are satisfactory to eliminate contamination of the ordinary, but closings often necessary to remove the cake from the DE filters, cartridge filters replaced. Cake or other solid growth is determined or estimated from the pressure increase or decrease flow. cake and / or other solid material usually can not be removed from the cartridge filter, which uses a porous medium return or otherwise. Dear cartridge filters must be replaced.
Unfortunately, caking and particulate filter loading is not the only cause of decreased flow or increased pressure. Gelling agents, brokers and viscosifying as brines, drilling mud cleaning debris, and other well fluids widespread use greatly increases the frequency of the filter fouling. They can be a liquid dissolves powder circulation "pill" viscosifying decisions, and any other means, or different solutions, of course, the hydrocarbon production of art. Gels or viscous liquids, most often, hydroxyethylcellulose (HEC), but often introduced xanthan gum, guar gum of various derivatives, polyacrylamide and other synthetic water-soluble polyacrylates in the wellbores.
When you spread the gel to encourage agents to reach back in the tank or liquid storage facility, they may remain unchanged or to complete the mixing of liquids. Almost immediately the gel to encourage agents to enter the filter, they are likely to blind off the DE filter or plug the cartridge filters. This blinding off to be a total closure and cleaning of the filter, as previously described. DE filter case, at least one hour before the filter can be updated, costing valuable rig time and costs. Changing the filter cartridge, as well as time consuming and expensive, as the filter pods may have more than fifty (50) per housing elements.
Current good practice in the treatment of liquid filtration, there is no defense against fouling polymer and liquid helium rapid access to the filters. Sudden and drastic reduction of flow and pressure increases are common and filter operators must be prepared almost without warning and close the filter action to return them in working order. Such discontinuities in the normal procedure is very expensive, especially for offshore platforms and other remote sites.
Another re-use and treatment of fluid is difficult, and the preparation of fresh food, is that the polymer additive concentration may be too high or too low. Processed liquid, where the desired number of extras, too, but there are different levels through the effective use make the most efficient way to apply them, as well as adjusting the polymer concentration is staggering.
