Amylase for Oilfield Starch & Filter-Cake Cleanup
Amylase for Oilfield Starch & Filter-Cake Cleanup
Evaluate alpha-amylase for starch-based drilling-fluid additives and filter-cake cleanup. Screen the actual starch grade, carrier fluid and treatment temperature to select a practical starting enzyme.
Match the Enzyme to Your Drilling-Fluid Additives
Starch-based additives
Alpha-amylase cuts internal α-1,4 bonds in starch, producing shorter dextrins that can reduce the contribution of starch to fluid viscosity.
Modified drilling starches
Crosslinking, chemical modification and accessibility can change enzyme response. Evaluate the exact starch grade used in the drilling fluid.
Starch-rich filter cake
Investigate starch breakdown within representative filter cake, alongside mineral-solid removal and permeability measurements.
Explore Enzymes for Laboratory Screening
These are evaluation candidates. Downhole suitability, dose and treatment time are established using the actual fluid and operating conditions.
alpha-Amylase (high temp)
A high-temperature alpha-amylase candidate for starch-breaker screening. Product temperature data must be confirmed in the complete brine and mud system.

alpha-Amylase (medium temp)
A medium-temperature alpha-amylase candidate for comparative laboratory trials under suitable treatment 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.
