Fisher Environmental Limited supplies environmentally responsible fluids for the drilling, tunnelling and shaft-sinking sectors.
It specialises in polymer-based fluid solutions and its research and development centre uses the latest particle charge analysing technologies.
Fisher provides a complete portfolio of oil processing chemistry, featuring industry standard products as well as leading edge technology.
Drilling Mud Additives
Fisher`s drilling mud additives are formulated to improve the properties of both fresh and seawater muds for efficient operation and better down hole performance. These drilling additives support a ``total system`` approach to controlling major mud properties.
They are particularly effective where faster drilling of slough shale is required, and where environmental considerations require the use of non-toxic drilling fluids and additives.
Fluid Loss Control – Fisher PAC/CMC/Xanthan Drilling Mud Additives
These are purified products specifically designed to protect the integrity of the bore. They control fluid loss without increasing viscosity (PAC/CMC LV) while stabilising and controlling gel strengths establishing a tough, flexible well cake along the well bore. The PAC/CMC HV range adds viscosity to the system without the need for polyacrylamides.
Viscosifiers and Shale Stabilisation – Fisher Anionic Polymer Range
These additives increase viscosity improving mud rheology to help clean the hole and lubricate the bit.
These additives reduce problems with sloughing shale`s, which allows faster penetration rates with less equipment wear.
Thinners and Rheology Control Additives – Fisher Drilling Fluid Thinners
Viscosity and gel strength can be reduced and fluids loss control improved as solids are deflocculated with Fisher additives.
Bentonite Extender – Fisher EX
This product is specifically designed for low solids, non-dispersed drilling technology, which extends the yield of bentonite and encapsulates low yield drilled solids for subsequent removal.
Fisher EX extender enables the drilling engineer to maintain active solids below 5% for fast drilling rates.
Solids Control – Fisher Flocculants and Coagulants
These additives effectively reduce low yield drill cuttings without removing beneficial bentonite in both dispersed and non-dispersed drilling fluids
Dewatering of Drilling Mud`s - Fisher Flocculants and Coagulants
Fisher has a wide range of unique polymers for thickening and dewatering difficult-to-treat drilling mud sludge`s.
Cement and Stimulation
Fisher Flocculants
Fisher Floc additives are low molecular weight anionic copolymers used to prevent fluid losses in the formation. There is also a large range of cationic charged polymers and high molecular weight viscosifiers.
Produced Fluids
Demulsifiers and Deoilers – Fisher flocculants
A new line of high charge cationic polymer demulsifiers and deoilers has been developed to treat reverse oil-in-water emulsions.
These new chemistries are very effective in rupturing the emulsifier stability of oil droplets creating coalescence and flocculation, generating fast water-oil separation.
Scale Control – Fisher Scale Inhibitors
These scale inhibitors are widely used for injection water treatment, “topside” scale control and ``squeeze`` treatments.
These products are very effective in the control of calcium and barium scale-forming species.
Water Clarification - Fisher Flocculants and Coagulants
Fisher`s water-soluble polymers are used worldwide for the clarification of produced water for re-injection or environmental disposal. The wide range of products are specifically designed to meet the stringent processes and regulatory limits on suspended solids, BOD, COD, oil and grease, heavy metals, colour and turbidity.
Mobility Control Polymers
Enhanced Oil Recovery (EOR) – Fisher Polymers
Fisher polymers are a unique family of liquid and dry anionic polymers designed to meet the critical requirements of the various chemically enhanced EOR processes.
Manufactured to optimise anionic charge and molecular weight these products offer a wide range of viscosity development and mobility control properties.
Refining and Petrochemical
Fisher`s product line of water-soluble polymers spans a wide range of chemistries, physical forms, molecular weights and charge values specifically formulated for efficient operations and optimised performance.
