Cross-linking lost circulation plug
FORM‐A‐PLUG II pumpable lost circulation plug is a blend of borate mineral and polymers designed for suspension, fluid‐loss control and cross linking technology. When activated with time and temperature, FORM‐A‐PLUG II develops a rigid crosslinked gel structure that effectively prevents loss of fluid to the formation. The FORM‐A‐PLUG II material is acid soluble, more than 95 percent being dissolved on contact with a solution of 15 percent HCl.
FORM‐A‐PLUG II fluid‐loss‐control plug is the main additive used to form an acid‐soluble, lost‐circulation plug, which can be used in any application where a squeeze plug would be beneficial. It is particularly advantageous in areas where loss of whole mud is prevalent. FORM‐A‐PLUG II product can be used to stop losses occurring with any water‐base and non‐aqueous‐base fluid system. FORM‐A‐PLUG II plug is used for suspension, fluid‐loss control and cross linking in the lost‐circulation plug.
FORM‐A‐PLUG II material can be used in combination with FORM‐A‐PLUG ACC accelerator and FORM‐A‐PLUG RET retarder. Together they will make a chemical reaction to form a rigid crosslinked gel structure. It is therefore important to carefully control the product concentrations and mixing conditions in order to ensure that the reaction proceeds as expected.
Advantages
- Provides suspension, fluid-loss control and cross-linking
