Process fluids preventing reservoir fluids migration in the annular space during well construction
Well construction technology should provide high-quality separation of reservoirs, the reliability and durability of an object as well as prevent penetration of plugging solution and working fluid in a reservoir bottom-hole zone, maintain its reservoir characteristics. However, the problem of qualitative cementing is still unsolved - full prevention of the reservoir gas show is not possible despite the use of modern annular packer elements, improved compositions of plugging solutions, etc. One of the important ways of solving the problem of reservoir fluids migration in the annular space is the use of special process fluids during well construction.
