Fluid Loss Control Additives are designed offshore, onshore oilfield cementing applications


Blended Asphalt

Blended Asphalt product which can effectively control and reduce mud filtrate in both water-based and oil-based fluids systems. Blended Asphalt filtration control agent disperses without the aid of wetting agents. It does not change formation wettability and so has particular application in reservoir fluids systems designed. It is the principal filtration control additive in the all-oil coring fluid and can be used in temperatures approaching 400°F (204°C). It can promote borehole stability, compatible with oil-based and water-based fluids, and can minimize differential sticking.

CELLOSIZE Hydroxyethyl Cellulose

CELLOSIZE Hydroxyethyl Cellulose is a nonionic, water-soluble polymer that can thicken, suspend, bind, emulsify, form films, stabilize, disperse, retain water, and provide protective colloid action. It is readily soluble in hot or cold water and can be used to prepare solutions with a wide range of viscosities. It has outstanding tolerance for dissolved electrolytes. It is a viscosifier in workover and completion fluids. It helps provide clear, low-solid fluids that impart minimum formation damage. As a thickener for spray emulsions, CELLOSIZE Hydroxyethyl Cellulose reduces drift and permits more efficient spray directly on foliage. It is an effective film-former, binder, thickener, stabilizer, and dispersant in shampoos, hair sprays, neutralizers, creams and lotions. CELLOSIZE Hydroxyethyl Cellulose is a useful gloss and ink hold-out size for paper and paperboard.

Oilfield Cement Additive Fluid Loss Control LT-FW by MIDAS IP

MID-C301 is a synthetic polymer used to control filtrate loss in all cement Slurries. It has minor retardation properties when used at low temperatures. This additive can be added to dry cement or the mix water.

MID-C301 can be used in fresh water and sea water slurries and can be applied in wells with temperatures between 80 to 200 ℉.

The recommended concentration is 0.5% to 1.2% (BWOC) depending on slurry’s weight, well’s temperature and solids to water ratio.

Oilfield Cement Additive Fluid Loss Control MT-FW by MIDAS IP

MID-C302 is a synthetic polymer used to control filtrate loss in all cement conditions.

This additive is primarily a fluid-loss control additive which can be used in cement slurries mixed with fresh water.

MID-C302 exhibits dispersant properties to some extents and can be applied in wells with temperatures between 100 to 250℉.

The recommended concentration is 0.5% to 1.5% (BWOC) depending on slurry’s weight, well’s temperature and solids to water ratio and can be added to dry cement or the mix water.

Polyanionic Cellulose (PAC)

Polyanionic Cellulose (PAC) Drilling Additive PAC, short for polyanionic cellulose, is a kind of water-soluble cellulose ether derivative made from natural cellulose by chemical modification, and an important kind of water-soluble cellulose ether. Usually the sodium salt of Polyanionic Cellulose is in application and widely used in petroleum drilling, especially in salt well and offshore oil drilling. In the shape of white to light yellow powder or particles, Polyanionic Cellulose is tasteless, nontoxic, strong in hygroscopicity, and freely soluble in cold and hot water. Polyanionic Cellulose polymer has excellent heat-resistant stability, salt tolerance and strong antibacterial activity. The slurry or fluid prepared from the product has better fluid loss reducing capability, rejection capability and higher temperature tolerance. Polyanionic Cellulose is widely used in petroleum drilling, especially in salt well and offshore oil drilling. Polyanionic Cellulose is more suitable for offshore drilling and the functions of Polyanionic Cellulose in drilling fluid are listed as below. 1). The drilling mud is the suspended matter of solids in the aqueous solution, and the same as other colloidal suspension dispersions, so has a certain life period. Polyanionic Cellulose can keep it stable and then prolong its life period. It has more obvious effects especially in mud suspension dispersions with dissolving salt. 2). The drilling mud with Polyanionic Cellulose can form thin and solid shaft wall as well as filter cake with low permeability, and thus can reduce the hole shrinkage and collapse phenomena resulting from water loss of mud. 3). The mud with the addition of Polyanionic Cellulose is seldom affected by mycete, so it doesn?t need to maintain high pH value or use p

Polyanionic Cellulose LAB GRADE

PAC, divided into high viscosity (HV) and low viscosity (LV), are the high-tech products with independent intellectual property right. As anionic cellulose ether, it features high purity, high replacement and well distribution and can be taken as thickener, rheology modifier and fluid loss agent. HV and LV PAC with excellent filtration reduction are indispensable products of slurry combination. High quality PAC is white flowing powder and its water solution is transparent viscous liquid. As water soluble polymer, it has the following functions and properties:

1.Rapidly dissolved in cold water or hot water
Able to be thickener, rheology control agent, adhesive, stabilizer, protective glue, suspending agent and water retaining agent.

In oil drilling industry, PAC is a kind of good drill slurry treating agent and fluid dosing material, featuring high mud yield and excellent salt resistance. To fresh-water mud, seawater mud and saturated brine mud, PAC is an excellent filtration reducer and has superior viscosity increasing ability and high temperature resistance (150℃), applicable for formulating fresh water, seawater and saturated brine completion fluid. Besides, it can formulate completion fluids with various densities when weighing calcium chloride and can make the completion fluid have certain viscosity and lower filtration loss. The HV and LV PAC products meet the standards of GB/T 5005, OCMA and API 13A.
