Effective Filter Cake Clean-Up

Do you or your clients share any of the following problems faced by well operators, using conventional  technology?

• Residual mud cake damage reducing well productivity and NPV
• A need for improved mud damage removal for horizontal wells where lower draw down limits the scope for wells to “self clean” when wells are brought into production, particularly in lower permeability formations
• Ineffective damage removal when using conventional acids because reactive acid penetrates the mud cake on contact and leaks off to the formation before the whole interval can be filled with treatment fluid and uniformly acidised
• Constraints on operations because conventional acids such as 15% HCI are hazardous to handle and require corrosion inhibitor additives which have a high environmental impact and are costly
• Concerns over aggressive acids leading to the possibility of corrosion  damage to increasingly complex completions

If so, Cleansorb’s Arcasolve™ family of downhole acidizing fluids could help you maximize your well’s potential!

Arcasolve™ fluids offers unique advantages, which include the following:

• High efficiency mud filter cake clean up which maximises regain permeability
• Mixing and pumping can be achieved with standard oilfield equipment
• Acidising (and polymer breaking in the case of Arcasolve) can be achieved in a single treatment.
• Arcasolve™ / Arcasolve Orca™ formulations and spent Arcasolve™ / Arcasolve Orca™ fluid are normally non-hazardous, low toxicity and have very low environmental impact
• Arcasolve™ / Arcasolve Orca™ fluid is non-reactive when placed which minimizes corrosion and helps ensure uniform acidizing and damage removal across long horizontal sections
• The treatment fluid can be placed in a variety of ways at high or low rate as required without compromising treatment performance
• The process is particularly suited to use at remote locations where equipment availability may be limited and low hazard operations are particularly important.
