Abstract [en]

Over past decades, technology innovation drove unconventional resources become conventional. Incorporating the technologies applied in shale gas development, exploiting tight oil comes into stage recently. Advanced technology such as long horizontal wells combined with massively hydraulic fracturing was established as necessity to exploit tight oil reserve, however, primary recovery remains as low as 5.0-10.0% of original oil in place in tight oil reservoir with these technologies applied.[1] Nanotechnology was regard as green and efficient alternative in E&P phase of petroleum industry because of its mechanical, chemical, thermal, electronic, optical, and magnetic properties. Feasibility study of it applied in tight oil E&P was investigated. The thesis presents description of tight oil and methods to extract it in details, also distribution of tight oil resource and outlook of future market were shown. In addition to literature review, reservoir simulation within tight oil development carried out to seek potential technical solutions, WAG (water alternating gas) process tend to be an excellent methodology to recovery tight oil. After a number of studies on the emerging technologies in tight oil E&P, associated with simulation works, on the basis of increasing fracture density, decreasing oil viscosity and increasing wettability alteration,[2] several technical solutions, like unconventional stimulation, CO2 foam, air injection(low temperature oxidation), and NAG(nanofluids alternating gas), etc. are recommended in the exploitation of tight oil reservoir.
