Dr Hamidreza Saghafi , the inventor of this product, is the head of thermal and chemical research in EOR institute of National Iranian Oil Company(NIOC)and one of the pioneers of this Technology. He started his survey on this project on 2009 and studied and experimented on different properties if this Gel. After some time he finally could achieve this success with the support of EOR institute of NIOC and design and produce a new model of Preformed particle Gel(PPG) for the first time that can resist the high temperature and salinity of an oil reservoir.
He has published 2 books about this product and is about to publish the 3rd chapter of his books about PPG.
All the used and published researches and sources are available online and on reliable sources(e.g. google scholar, Elsevier pub. , Canadian journal and etc)
E have to say that , PPG is a new product and technology that is used for conformance control in oil & gas reservoirs and can resolve a lot of problems that cause low recovery In Oil fields.
This product can also change the permeability of reservoirs and has some other properties that make it a useful tech. for oil industries. Some of this properties are listed below:
Adjustable size that varies from micro to millimeter
Resistant in saline media
This gel can swell up to 200 times of its original
Adjustable swelling ratio
Adjustable swelling rate
Adjustable mechanical properties
