You can use this term when referring to the part of the oil industry that involves exploration and extraction of oil. For example: "We have invested heavily in upstream production to boost our oil reserves."
Without this, the bioprocess will be constrained, despite the best efforts to maximise the upstream production kinetics and downstream product recovery.
Midstream assets refer to the transportation and storage systems that move crude or refined products from the upstream production and refinery sites to the downstream retailers.
The Oil and Gas segment designs, manufactures, and supports products and service solutions in upstream, production, transportation, refining, and related industries.
FERC rejected the organizations' call for consideration of indirect effects related to induced upstream production and downstream natural gas consumption.
BP has whittled down its portfolio of refineries in recent years to a core of high-grade facilities integrated into broader operations such as trading and upstream production.
He predicted that Russian oil production would decline between 3 and 5percentt in 2009, given the disincentives for upstream production, falling prices, and the credit crunch.
In order to develop a new flexible transfer line (FTL) that links upstream process production line and downstream process production line, production engineers must decide the parts input sequence to FTL.
After individually optimizing the process conditions, the upstream MVA production (84.0 g/L, 34.0% and 1.8 g/ L/h) and downstream isoprene production (11.0 g/L and 0.23 g/L/h) were greatly improved in this two-step process.
Its weightiest charge is that the takeover would allow BP Amoco to dominate upstream oil production in Alaska, where BP Amoco and Arco together control some 70% of oil reserves.
Just forcing the big six to sell all their upstream power production to anyone who wants it downstream, would allow new entrants into the market, which might have been enough to reset it.
These findings are shown to be largely insensitive to uncertainties in the upstream fuel production GHG emissions, with the exception of the land use change (LUC) for bioethanol.
