Phases of petroleum industry

There are two phases of petroleum industries.

1. Drilling.

2. Production.

1. Drilling :

Drilling is a cutting process that uses

a drill bit to cut a hole of circular

cross-section in solid materials.

The drill bit is usually a rotary cutting tool,

often multi-point. The bit is pressed

against the work-piece and rotated at

rates from hundreds to thousands of

revolutions per minute.

Drilling is becoming an increasingly

important tool for environmental protection

and remediation. Drilling is a relatively

noninvasive method for investigating

and removing chemical and radioactive

wastes from the subsurface, and for

placing barriers in the subsurface

to halt the spread of contamination.

2.Production:

Petroleum production engineering

is a subset of petroleum engineering.

Petroleum production engineers design

and select subsurface equipment to

produce oil and gas well fluids.

Petroleum is a fossil fuel, meaning

that it has been created by the

decomposition of organic matter over

millions of years. Petroleum is formed

when large quantities of dead

organisms–primarily zooplankton and

algae–underneath sedimentary rock are

subjected to intense heat and pressure.

Production is a process in which we produce

or transfer the crude oil from subsurface to

surface.
