Potential technical solutions to recover tight oil: Literature and simulation study of tight oil development
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.
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
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, 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.
