Integrated Drilling BHA Helps Ecopetrol Eliminate NPT Related to Hole Instability in Depleted Field

Publication Date: 02/19/2016

Ecopetrol was drilling in the Chichimene field, which is characterized by high depletion levels, overpressured and unstable formations, and alternating lithology. These features pose high risk of stuck pipe and casing as well as wellbore stability issues. Using the casing circulating tool, Ecopetrol completed three trips without incurring HSE, NPT, or service-quality issues related to hole instability.
