Upstream process & Advancement
It is a process of finding and producing the
natural form of oil called crude oil
and natural
gas.
The process is also called exploration and production (E&P). This process
involves exploration, drilling, recovering the crude oil
and natural
gas. The target of the E&P companies is to improve the
production rate and providing safe operation and reduced risk to the
environment. The first step in the petroleum industry
is the upstream
process. The last step of the upstream
process is the P&A (Plug and Abandonment).
