Subsurface technologies present an excellent opportunity to produce hydrogen from
hydrocarbon resources. It refers to the production of hydrogen directly from underground …

With the growing demand of oil worldwide, heavy oil has increasingly become vital in the
world energy market. However, further development of heavy oil reservoirs are limited by …

Canada has declining reserves of conventional oil, but vast reserves of heavy oil and
bitumen. Over 90% of the world's heavy oil and bitumen trapped in sandstones and …

In the Expanding-Solvent Steam-Assisted Gravity Drainage (ES-SAGD) process, solvent
added to injected steam mixes with the oil at the edge of the depletion chamber to help …

Steam injection is a widely used oil-recovery method that has been commercially successful
in many types of heavy-oil reservoirs, including the oil sands of Alberta, Canada. Steam is …

Laboratory and field data, although limited in number, have shown that steam/solvent
coinjection can lead to a higher oil-production rate, higher ultimate oil recovery, and lower …

After a cyclic steam stimulation (CSS) process achieved accidental success in recovering
heavy oil resources in the 1960s, thermal recovery processes started to unlock the door of in …

About one-quarter of the 1.7 trillion barrels of bitumen resource located in Alberta, Canada is
hosted in thin reservoirs with thickness less than about 10m and is at this time considered …

Steam assisted gravity drainage (SAGD) is a thermal hydrocarbon recovery method by
which extra-heavy oil is produced through steam injection and bitumen heating. The …

Steam-assisted gravity drainage (SAGD) is a mature heavy oil thermal recovery technology
but inherently limited to low recovery efficiency at mid-late stage due to the increasing heat …
