What is upstream refining?
Also called exploration and production (E&P), upstream is farthest from the end-user consumer in the oil & gas supply chain. Upstream activities include exploration, drilling, and extraction. Upstream is followed by midstream (transportation of crude oil) and downstream (refining and distribution) phases.
What is upstream and downstream in refinery?
Simply put, upstream works include the exploration and production of crude oil and natural gas, whilst downstream refers to the processes applied after extraction through to it being delivered to the customer in whatever format required.
What is the meaning of upstream process?
Upstream Processing refers to the first step in which biomolecules are grown, usually by bacterial or mammalian cell lines, in bioreactors. When they reach the desired density (for batch and fed batch cultures) they are harvested and moved to the downstream section of the bioprocess.
What is the meaning of upstream and downstream?
Stream – The moving water in a river is called a stream. Upstream – If the boat is flowing in the opposite direction to the stream, it is called upstream. In this case, the net speed of the boat is called the upstream speed. Downstream – If the boat is flowing along the direction of the stream, it is called downstream.
What is upstream manufacturing?
Upstream processes are those in which biological materials are either obtained from an outside source or inoculated and grown in culture, under controlled conditions, to manufacture certain types of products. Downstream processes are those in which the products are harvested, tested, purified and packaged.
What is the difference between upstream and downstream in oil & gas?
What Is the Difference Between Upstream and Downstream in the Oil and Gas Industry? Upstream oil companies are involved primarily with oil discovery, extraction, and production. Downstream oil companies instead deal with refining and delivering petroleum products to consumers.
Is refining midstream or downstream?
The downstream sector is the final stage of the process and refers to the refining, processing and purifying of crude oil and natural gas.
What are the process of upstream processing?
Upstream processing comprises tasks in the initial stages of the fermentation process in biotechnology. This includes all steps related to the development of microorganisms, nutrient preparation, cell culture, cell separation and harvesting.
What is the aim of upstream processing?
The goal of upstream biomanufacturing is to grow cells that will produce a desired protein, the protein being further purified during the downstream processing steps (see Downstream Processing chapter).
Which process is an upstream process?
Is LNG upstream or downstream?
LNG is in the midstream of the oil and natural gas value chain, taking supply from upstream, producing product at the midstream and selling into markets downstream.
What is the difference between upstream and midstream?
‘Upstream’ is about extracting oil and natural gas from the ground; ‘midstream’ is about safely moving them thousands of miles; and ‘downstream’ is converting these resources into the fuels and finished products we all depend on.
What is the purpose of upstream manufacturing?
What are the basic difference between upstream and downstream processing?
The key difference between upstream and downstream bioprocessing is that upstream bioprocessing involves screening and identification of microorganisms, media preparation, multiplication of microbes inside a bioreactor, and incubation, while downstream bioprocessing involves extraction, purification and packaging of …
What is midstream refining?
Midstream refers to points in the oil production process that falls between upstream and downstream. In particular, midstream activities include the storage, processing, and transportation of petroleum products. These may include companies that specialize in operating tanker ships, pipelines, or storage facilities.
Are refineries midstream?
As expected, the midstream sector is the second of the three petroleum market stages. The category refers to the transportation of crude or refined petroleum products, usually via pipeline, oil tanker, barge, truck or rail. The final destination is refineries which will then commence the downstream process.
What is the difference between upstream and downstream manufacturing?
Upstream refers to the material inputs needed for production, while downstream is the opposite end, where products get produced and distributed.
What are the processes in an upstream process?
Upstream processing involves all the steps related with inoculum development: Media Preparation, Cell Culture and Cell Separation & Harvest. When the cells have reached the desired density, they are harvested and moved to the downstream section of the bioprocess.
What is upstream production?
Upstream refers to points in production that originate early on in the processes. Also called exploration and production (E&P), upstream is farthest from the end-user consumer in the oil & gas supply chain.
What is upstream oil and gas?
Upstream is a term for the exploration and production stages in the oil and gas industry. It is the first stage in oil or gas production, followed by the midstream and downstream segments.
What is the origin of the word upstream?
The first known use of upstream was in 1681. English Language Learners Definition of upstream. : in the direction opposite to the flow in a stream, river, etc. : toward the source of a stream, river, etc.
What is the meaning of upstream biochemistry?
Definition of upstream. 3 biochemistry : toward the beginning of a series of cellular processes : preceding a linked molecular event occurring in a sequence Many signaling pathways possess intrinsic negative feedback by which a downstream event in a pathway turns off an upstream event.— Harvey Lodish et al.
