==RIGLESS METHOD FOR SELECTIVE ZONAL ISOLATION IN SUBTERRANEAN FORMATIONS USING POLYMER GELS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17644217 titled 'RIGLESS METHOD FOR SELECTIVE ZONAL ISOLATION IN SUBTERRANEAN FORMATIONS USING POLYMER GELS

==Simplified Explanation==

The patent application describes a method for zonal isolation in a subterranean formation, which involves creating a gel that prevents fluid flow in a specific zone of interest. The method includes several steps and considerations:

* Identifying the zone of interest within the subterranean formation.
* Determining the static temperature of the zone of interest.
* Determining the time duration for the gelation of a treatment fluid.
* Determining the concentration of a cross-linker in the treatment fluid.
* Determining the volume of the treatment fluid to be delivered to the zone of interest.
* Determining the correlation between cooling of the wellbore near the zone of interest and the delivery rate of the treatment fluid.
* Determining the target wellbore temperature.
* Delivering a cooling stage until the target wellbore temperature is reached.
* Delivering a treatment stage to form a gel that is impermeable to fluid flow within the zone of interest.

Potential applications of this technology:

* Zonal isolation in oil and gas wells to prevent fluid migration between different zones.
* Controlling fluid flow in geothermal wells to optimize heat extraction.
* Isolating contaminated zones in environmental remediation projects to prevent further spread of pollutants.

Problems solved by this technology:

* Ensuring effective zonal isolation in subterranean formations to prevent unwanted fluid flow.
* Optimizing the gelation process by considering factors such as temperature, cross-linker concentration, and delivery rate.
* Improving the efficiency and reliability of zonal isolation techniques.

Benefits of this technology:

* Enhanced zonal isolation, reducing the risk of cross-contamination and improving well performance.
* Improved control over the gelation process, leading to more precise and predictable results.
* Increased efficiency and cost-effectiveness in subterranean operations by minimizing the need for remedial work and repairs.


==Original Abstract Submitted==

A method for zonal isolation in a subterranean formation includes identifying a zone of interest within the subterranean formation, determining a static temperature of the zone of interest, determining a time duration for gelation of a treatment fluid, determining a concentration of a cross-linker in the treatment fluid, determining a volume of the treatment fluid to be delivered to the zone of interest, determining a correlation between cooling of a wellbore near the zone of interest and a delivery rate of the treatment fluid, determining a target wellbore temperature, delivering a cooling stage until the target wellbore temperature is reached, and delivering a treatment stage. Delivering the cooling stage and the treatment stage results in forming, within the zone of interest, a gel that is impermeable to fluid flow.
