  • 1.  Deep heavy oil reservoir

    -------------------------------------------
    Can anybody share any kind of information about mature technologies for application in deep heavy oil reservoirs. I have some extra heavy oil crude assets at depths greater than 6,000 feet but mobile at reservoir conditions. Temperature overcomes 200 ° F, Gas Oil Ratio greater than 70 Scf/Bl, viscosities 300-1,000 cp at reservoir conditions.

    Carlos,
    I understand that electrically heated wells have been deployed and also you could consider injecting light diluent or hot water downhole.  ESP's can also be used to lift the fluid to surface.  Need to take care with emulsions, particularly if they are stable.  The use of hot water downhole could allow you to control the water cut in the well such that the emulsified mixture viscosity is reasonable.

    1. I have gone thru the reservoir description you have given. It really matches to the conditions of one of our asset but with a difference of well depth to the tune of 600 to 800 ft.
    2. Presently we are producing that field under Thermal EOR Project.
    3. I suppose you can try Steam Huff & Puff technique by using mobile or skid mounted boilers.
    4. Another solution is to put Jet Pumps on these wells and use hot water as Power Fluid.

    Regards
