DESCRIPTION OF PAC POLYANIONIC CELLULOSE
PAC Polyanionic cellulose a substance which can be added to drilling muds, counting on the intended application and desired properties of the mud include detergents, foaming agents, defoaming agents. Having fluid-loss control , shale inhibition and salt tolerance. It is useful for water-based drilling fluids as well as in low-density brines, for one or a lot of functions.
USAGES OF PAC POLYANIONIC CELLULOSE
PAC Polyanionic cellulose is characterized by such behavior in solution as allows reduction of the fluid loss with relation to the bottom fluid while not the soluble polymer. Water soluble polymers particularly most popular are referred to as polymer have varied substitution degrees and molecular weight. The behavior and result of this viscosifier in an exceedingly lubricator typically depend upon the scale of the polymer’s molecules and their charge (e.g., anionic, cationic, or non-ionic).
PAC Polyanionic cellulose is additionally Fluid loss reducers could use in a mud in step with this invention if desired. Some common fluid loss reducers embrace, for instance, starches or CMC and a number of these chemicals may have a viscosifier perform. This excellent loss reducers could give steric stabilization for the non-ionic Surfactants.
Both water and organic solvents will function the basis for drilling fluids; but today’s environmental protection needs and technological options of well processes verify the employment of water-based drilling fluids in most cases. Since PAC Polyanionic cellulose could be a soluble polymer, it’s utilized as an additive that improves performance. In conclusion most known features of this properties below.
– Due to its film-forming functions, it slows down the erosion of the walls of the well, preventing it from falling asleep.
– Improves the cooling and lubricating
– Contributes to the upkeep of thermal and biological stability of mud.
