The Division of Vitality’s (DOE’s) Workplace of Fossil Vitality introduced as much as $88 million in federal funding for cost-shared analysis and improvement initiatives enhancing applied sciences for oil and pure fuel restoration underneath two separate funding alternative bulletins (FOAs). The Nationwide Vitality Know-how Laboratory (NETL) will handle the initiatives chosen underneath each FOAs.
In response to the US Vitality Info Administration (EIA), proved reserves of US crude oil and pure fuel reached report highs in 2017, topping earlier information at 39.2 billion barrels. As well as, proved reserves of pure fuel sources reached 464.three trillion cubic toes (Tcf) in 2017, beating the 2014 report of 388.eight Tcf. EIA additionally notes that shale fuel made up 66 p.c of complete proved reserves of pure fuel in 2017. This success in proved reserves of each oil and fuel are due partially to DOE’s analysis applications.
Nonetheless, regardless of the big volumes of oil and fuel at present being produced from U.S. typical and unconventional sources, a majority of US oil stays within the floor; in some circumstances roughly 90% of in situ oil is just not recovered with present applied sciences.
The primary funding alternative is for $44 million underneath DE-FOA-0001988, Superior Applied sciences for Enhanced Oil Restoration.
Frequent typical enhanced oil restoration (EOR) strategies at present in follow embrace miscible fuel injection (each flooding and huff-n-puff); thermal applied sciences (steam flooding and steam huff-n-puff); and chemically enhanced waterflooding (e.g., surfactant, alkaline and polymer flooding).
Carbon Dioxide miscible flooding is the commonest EOR technique, chargeable for about 293,000 barrels per day of incremental US oil manufacturing in 2014. Thermal strategies are the second hottest, accounting for about 285,000 barrels per day in 2014.
Nonetheless, a research carried out for DOE by Superior Sources Worldwide estimates that carbon dioxide miscible flooding alone, if utilized to all amenable reservoirs, may improve home oil manufacturing by three to four million barrels per day.
The goals of this FOA are to solicit and competitively search analysis purposes to speed up the event and utility of applied sciences for enhancing the restoration of petroleum from each onshore typical and unconventional reservoirs by way of the injection of chemical, miscible, or thermal fluids.
The initiatives chosen underneath this FOA will give attention to decreasing technical dangers related to EOR and increasing the applying of EOR strategies onshore, each in typical and unconventional reservoirs. The initiatives will even enhance the understanding of unconventional reservoirs and enhance restoration elements for these performs. Idea papers should be submitted by 25 January 2019. DOE anticipates choosing as much as six initiatives for this FOA.
The second alternative, additionally for $44 million in funding underneath DE-FOA-0001990, Superior Applied sciences for Restoration of Unconventional Oil & Gasoline Sources, will help initiatives to boost the characterization of rising unconventional performs and to enhance the last word restoration of oil and fuel sources from unconventional reservoirs.
Unconventional Oil and Gasoline (UOG) improvement has considerably elevated US manufacturing of oil and pure fuel over the previous decade. The EIA estimates that crude oil manufacturing from unconventional (tight oil) reservoirs has elevated from 16.5% of complete US manufacturing in 2008 (zero.eight million barrels of oil per day (MMb/d)) to 56.5% of complete US manufacturing in 2018 (5.6 MMb/d).
Over the identical interval, pure fuel manufacturing from unconventional reservoirs has additionally elevated from 16.eight% of complete US manufacturing (three.four trillion cubic toes (Tcf)) to 56.6% of complete US manufacturing (16.four Tcf). Primarily based on the EIA’s 2018 Annual Vitality Outlook, these traits are anticipated to proceed by way of 2050 when UOG sources are projected to contribute 70.1% of complete US oil manufacturing (7.9 MMb/d) and 76.1% of complete U.S. pure fuel manufacturing (32.7 Tcf).
Primarily based on these projections, UOG manufacturing from current and rising performs will proceed to play a significant position in US power by way of 2050.
Whereas the mixture of extended-lateral horizontal drilling and excessive quantity hydraulic fracturing has led to those vital manufacturing will increase, the complete potential of US UOG sources has but to be realized. The restoration effectivity of UOG is tough to certain, however the restricted info accessible means that restoration elements are sometimes extraordinarily low, maybe 20% in gas-rich shale reservoirs and fewer than 10% in liquid-rich performs.
This FOA seeks purposes which suggest analysis to develop instruments, strategies, and/or applied sciences that 1) enhance the last word restoration of UOG sources and a pair of) enhance the understanding and financial viability of rising UOG performs. These instruments, strategies and/or applied sciences are anticipated to be demonstrated in a related subject surroundings or validated underneath related laboratory situations. Profitable applied sciences will improve the understanding of UOG reservoir conduct to enhance restoration effectivity and/or increase the event of rising UOG performs.
Full purposes are due 25 February 2019.
