What is oil and gas upstream?

What is upstream and downstream

Oil, however, was formed from the remains of living beings (mainly plankton and algae) that were deposited on the seabed. Natural factors such as the passage of time, heat, strong pressures and the absence of oxygen caused this organic matter to decompose little by little, forming the oily substance we know today as oil. The crude oil remained deep underground, impregnating the porous rocks that form the deposits.

Once the deposit has been located and its viability has been proven, the second phase begins: extraction or production. To extract the gas or oil found in the reservoir, drilling techniques are used following the highest safety standards. In this phase we focus our efforts on obtaining the maximum yield from the reservoir in an efficient and responsible manner, minimizing the environmental impact and guaranteeing maximum safety in the processes. For example, thanks to the HEADS system.

What is upstream and downstream?

Downstream refers to all activities and operations in the oil industry that take place after oil extraction (upstream).

¿Qué significa upstream Oil and gas?

The hydrocarbons sector is composed of two main areas: one called upstream, which comprises exploration and production activities, and the other called downstream, which carries out transportation, refining and marketing activities.

What are upstream projects?

The Upstream sector includes the underwater or subsurface search for oil or natural gas fields from drilling and surface extraction operations for both fossil fuels. Types of Projects: Subway storage on-shore/off-shore. On-shore/off-shore exploration and drilling.

Upstream hydrocarbons

Downstream refers to all activities and operations in the petroleum industry that take place after oil extraction (upstream). In some cases, there is a further distinction with midstream activities in the downstream sector. The downstream sector includes transportation, processing and sales, i.e. all services ranging from transportation and storage of petroleum products to their sale in consumer markets.

What is an upstream process?

In the petroleum industry, the term upstream encompasses the entire process from the geological evaluation of petroleum reserves to the channeling of raw materials to the surface (extraction) and final delivery in refined/purified form.

What does downstream mean?

The downstream sector commonly refers to the refining of crude oil and the processing and purification of natural gas, as well as the marketing and distribution of crude oil and natural gas products.

What is upstream in Git?

When you push to a remote control and use the –set-upstream flag git sets the branch you are pushing to as the remote tracking branch of the branch you are pushing.

Upstream which means

Petroleum analysis Air Liquide supplies industrial gases, pure specialty gases and liquid and gaseous calibration mixtures under the ALPHAGAZ™ brand, increasing reliability and providing perfect calibration at upstream stages.

What is upstream on the Internet?

The terms “downstream” and “upstream” in reference to the Internet are other ways of saying “download” and “upload”. Downstream traffic flows to the user and upstream traffic flows from the user.

What activities are performed in the upstream?

This sector includes the search for potential crude oil and natural gas deposits, both subway and subsea, the drilling of exploratory wells, and subsequently the drilling and exploitation of the wells that bring the crude oil or natural gas to the surface.

What is upstream and downstream in Bioprocessing?

The upstream processes consisted of: selection and procurement of microalgal strains, study of production systems and design and implementation of a photobioreactor. The downstream processes included biomass recovery by flocculation, sedimentation, centrifugation and drying.

Midstream oil

In the oil industry, the term upstream encompasses the entire process from the geological evaluation of oil reserves to the channeling of raw materials to the surface (extraction) and final delivery in refined/purified form.

The upstream includes all phases that take place on the way to the refinery. In practice, the transition from upstream to downstream occurs when the crude oil is loaded onto the means of transport that will take it to the processing site. However, the main element of the upstream process is the geological analysis and exploration of oil reserves.

Therefore, the upstream services sector includes horizontal directional drilling, development of sensors for acquiring measurements while drilling (MWD), special software for evaluation of the collected data and construction of drilling engines.
