Case History

Repeated Savings and Use with FLC 2000® in the Gulf of Mexico

Gulf of Mexico
Challenge

A deepwater Gulf of Mexico (Mexico) operator experienced major mechanical
wellbore instability issues, including borehole collapse, hole closure (torque and
drag increase, stuck pipe), and lost circulation due to existing and induced
microfractures. This particular operator was an early adapter of FLC 2000 and
LCP 2000 (to prevent and mitigate lost circulation issues and associated nonproductive time).

Solution

FLC 2000 is well suited for this operator’s offshore wells. These wells are drilled
through depleted zones, high temperature and/or high-pressure zones, existing
microfractures and other wellbore stability challenges, such as induced fractures
and operating in a tight fracture and pore pressure environment. FLC 2000 is used
to enhance wellbore stability and to reduce induced losses while improving the
overall performance of the drilling fluid system.

Results

Since 2005, this operator used FLC 2000 to improve wellbore stability, lower
overall fluid cost and losses, reduce differential sticking, reduce the number of
sidetracks and increase the operational windows between the fracture and pore
pressure gradients. An internal review by the operator indicated improved drilling
times and lower NPT in excess of 60%, with average estimated costs savings in
excess of $500,000 per well, with the savings on many wells in the millions of
dollars.
