Wellbore stability is an oil-and-gas-industry business imperative. It is essential to the realization of a well’s economic potential throughout drilling, completion, and production phases. A properly designed wellbore architecture can help reduce the costs of primary operations by minimizing non-productive time due to drilling delays or even unplanned casing strings. It can also avert the need for remediation if designed to address fluid/gas flow in the annulus that can lead to wellbore integrity issues and/or interfere with production.
A properly designed resin system can help with wellbore stabilization and the hydraulic annular seal by complementing the cement sheath during drilling and completion operations. A resin system can also be used to regain wellbore architecture integrity should remediation be required. Lastly, a properly designed resin system can be used as a primary application with chemical disposal and injection wells and deliver secure plug and abandonment of wells at the end of life.
Lanlang ® IN-5 is an inert bead fine mesh form resin designed to be used as the mechanical lubricating agent for well drilling. Lanlang ® IN-5 can reduce the casing wear and has excellent thermal stability (up to 230°C).
