Detailed Description
SETC has independently developed the next-generation Supramolecular Gel-II Pressure Control and Lost Circulation Material, engineered to effectively seal severe loss zones in porous, fractured, and karstic formations.
The Supramolecular Gel-II Lost Circulation Material offers the following technical advantages:
The material spontaneously forms a robust gel structure through non-covalent interactions, eliminating the need for additional crosslinking agents.
The material demonstrates excellent thermal stability, maintaining performance at temperatures up to 160°C.
Upon entering the formation, the material forms a "gel slug" capable of withstanding pressure differentials up to 4.5 MPa, effectively sealing porous, fractured, and cavernous formations.
Compared to cement, the gel exhibits superior elasticity and toughness, integrating seamlessly with the formation post-gelation. This integration prevents block detachment during drilling operations.
The high-molecular-weight gel is compatible with both water-based mud (WBM) and oil-based mud (OBM), ensuring no adverse effects on drilling fluid properties.
The material can be used independently or in combination with other bridging and lost circulation materials. Its performance remains unaffected by temperature variations or environmental conditions, and it can be easily prepared on-site using standard mixing procedures.
