Cellulase for Oilfield Polymer Cleanup
Cellulase for Oilfield Polymer Cleanup
Evaluate cellulase for breakdown of accessible cellulose and susceptible cellulose derivatives in drilling-fluid residues and filter cakes. Match the activity to the specific additive and the intended post-drilling cleanup conditions.
Match the Enzyme to Your Drilling-Fluid Additives
Accessible cellulose
Cellulase cleaves cellulose chains. Evaluate polymer breakdown and the resulting change in fluid rheology.
Cellulose derivatives
Carboxymethyl cellulose (CMC) and polyanionic cellulose (PAC) are modified materials. Their susceptibility depends on substitution, accessibility and enzyme preparation; test the actual commercial grade.
Mixed filter cakes
Enzyme treatment addresses susceptible organic material. Mineral solids and bridging agents require a compatible removal strategy.
Explore Enzymes for Laboratory Screening
These are evaluation candidates. Downhole suitability, dose and treatment time are established using the actual fluid and operating conditions.
Cellulase
A starting liquid cellulase for laboratory screening of susceptible cellulose-based additives. Confirm compatibility and retained activity under your proposed well conditions.

Temperature & contact time
Measure retained activity over the intended treatment period at the actual fluid temperature.
Brine & pH
Screen salinity, ion composition and pH using the proposed carrier fluid, rather than water-only enzyme assays.
Complete mud system
Include the actual polymer grade, solids, other additives and any oil phase. Verify treatment placement and subsequent solids removal.
Your Fluid. Your Conditions. Your Enzyme.
Characterise the fluid
Send the formulation, polymer identities and a representative mud or filter-cake sample. Define the cleanup stage and performance target.
Compare enzyme options
Screen activities, dose, pH, temperature and contact time against untreated controls. Check compatibility with the complete formulation.
Validate performance
Confirm viscosity change and polymer breakdown, then evaluate filter-cake removal and permeability recovery in representative laboratory tests before field use.
Targeted polymer cleanup
Cellulase and amylase hydrolyse susceptible polysaccharide additives; they do not directly digest petroleum hydrocarbons or dissolve mineral bridging solids. Evaluate these activities as part of a complete drilling-fluid or filter-cake cleanup process.
