The New Biodegradable Surfactant Drilling Fluid for Offshore Drilling Environment

In oil and gas industry, there are many challenges faced before
reservoir fluid produced out of reservoir rock. In drilling progress, the
reservoir rock may be invaded by drilling fluid and cause several damage to
the wall formation. This is called as formation damaged. Formation damage is
defined as any type of a process which results in a reduction of the flow
capacity of an oil, water or gas bearing formation.
In oil and gas reservoirs, formation damage has known as a source of
serious productivity reductions as it could lead to water injectivity problems in
many waterflood projects. The injectivity problem has reduces the
effectiveness of recovery mechanism, mainly on third recovery mechanism.
Besides, formation damaged has negative affect to oil and gas production as it
could reduces the production due to its mechanism.
