Use of multipurpose wells equipment to enhance oil recovery

Involving low-productive intervals in the development of one deposit by means of the bottom-hole formation zone treatment does not always deliver a positive result, which is whya part of productive intervals in producers and injectors stay suspended for years. Some specialists consider that using dual production operation equipment and dual injection and production operation equipment can be a solution to the problem. This article states basic peculiarities andlimitations to be taken into consideration and implemented when using dual injection and production operation technology.
Materials and methods
Field research and pilot testing. Analytical evaluation by existing formulae.
Results
We reviewed an opportunity to use equipment for dual formation operation to enhance the hydrocarbon recovery.
Conclusions
One can use dual operation equipment when involving non-operating formations within one object; however, this is related to certain limitations and complications suppressing the working of this technology.
