Care in the Production
|
 |
At the production stage monitoring of the environment continues as the
teams proceed with the work.
When a gusher is discovered production equipment is installed, consisting
of control valves, surface pipelines and storage points, among others. For
offshore wells able to produce on a comercial scale, fixed or floating platforms
are installed and, upon them, the producing facilities. For submarine wells
the production control valves are installed in the bottom of the sea itself.

Down-the-hole equipment is provided with blowout valves to
prevent uncontrolled production or eruption of a well. Trained teams of men are constantly on the
alert to deal with any emergency to avoid or reduce any harm to the environment.
Crude oil is produced together with water. After being separated from the
oil and gas, the water is treated and discarded in such a way as not to cause
any harm to the environment. In some instances the water is injected back into
the reservoir rock to increase pressure therein and hence, output of the well.
The treatment to which the crude is subjected results in oily residues which
even if small in quantity are carefully handled to avoid any contamination
of surrounding areas.
New technologies permit reuse of liquids effenents resulting from production work.
