【 摘 要 】

Improving energy efficiency of hydrocarbon extraction processes at any stage of development of oil deposits is a prioritized field of work for oil industry of any region. Prospects of using complex technologies to harness hydrocarbon potentialities are shown on the example of two pilot projects for Pre-Urals foreland basin (Russia) and south Iraq. Application of gas technologies on Tereklinskoye (Russia) and Zubair (Iraq) fields will allow reducing the capital spending and increasing the oil recovery of each of the objects under consideration by at least 8-10% in comparison with depletion drive. For Tereklinskoye oil deposit, there are provisions to use natural gas as it comes from the major gas pipeline as a displacement agent. In Zubair field, gas injection may be arranged by means of gas delivery from a nearby gas deposit with high formation pressure. A prospect of creating a network of underground gas storage facilities in depleted reefogenic oil deposits of Pre-Urals foreland basin allows combining solution of the problem of energy security of the region with that of the problem of increasing oil recovery rate for depleted oil deposits to design values and above. Arrangement of underground gas storage facility is seen also as a strategic potential for further development of the area surrounding the field.
