In recent years, new advancements have been achieved in the reservoir description, reservoir engineering design, well drilling technology, well completion technology and producing technology for thin-layer reservoirs, high-cut-water thick-layer positive rhythm reservoirs, buried hill heavy oil reservoirs, extra-heavy oil reservoirs, and complicated fault-block reservoirs.
And consequently, a set of complete well completion technologies suitable for HTHP (high temperature and high pressure) and high-flowrate gas wells with acidic media was developed as follows.
Advances in high-throughput genotyping technology and completion of the Human Genome Project facilitate the development of genome-wide searches for genetic polymorphisms to SLE and LN.
This shale gas "revolution" was made possible primarily through the application of drilling and completion technologies, particularly horizontal wells completed in multiple hydraulic fracturing stages (multi-fractured horizontal wells, or MFHWs).
After many years of drilling practice and technical research, the following six key drilling and completion technologies for this type reservoir are established by introducing new tools and technologies, developing specialized drill bits and optimizing drilling design.
Enlisting the cooperation of nine companies that in many cases were using the best available well-completion technology — technology that will be mandated by the federal government by 2015 — they concluded that the methane leakage during the production of natural gas was a mere 0.42 percent.
"New and advanced exploration, well drilling and completion technologies are allowing us increasingly better access to domestic gas resources — especially 'unconventional' gas — which, not that long ago, were considered impractical or uneconomical to pursue," said John B. Curtis, a geology professor at the Colorado School of Mines and the report's principal author.
Adapted drilling and completion technologies.
Furthermore, integrating the matrix completion technologies into machine learning to solve the problem of incomplete data is also a very promising direction [106].
Even with current stimulation and completion technologies, many fields are expected to produce less than 10% of initial oil in place.
