Filter cake Dissolver

详情

Description: RE-CD2 filter cake dissolver is a delayed acid generator designed for the slow release of acid downhole. Upon contact with water, RE-CD2 reacts to generate acid gradually. This acid release process aids in dissolving calcium carbonate and starch components in the filter cake, thereby removing fluid damage. The product can be effectively placed across the entire interval before acid generation begins, enhancing overall clean-up efficiency.

Typical Physical Properties:

• Physical Appearance: Light yellow liquid
• Specific Gravity: 1.**8
• pH (1% Solution): **2.5
• Solubility in Water: **0%
• Flash Point: >**0°F (>*3°C)

Applications:

• Openhole Completions: Ideal for complete dissolution of filter cake, especially in long horizontal intervals where accurate placement before losses is critical.
• Low Temperature Applications: Can be used in conjunction with drilling detergent (RE-PDD) to ensure thorough removal of filter cake.

Recommended Treatment:

• The typical concentration of RE-CD2 filter cake dissolver ranges between *0% and *0% (v/v). However, the optimum concentration should be determined on a case-by-case basis considering specific conditions such as completion techniques and hole diameter.

RE-CD2 filter cake dissolver offers controlled acid release for effective filter cake dissolution, suitable for various well conditions and temperatures ranging from *5 **5°F (*5 *5°C).
