An operator set out to drill a delimitation well  and had some uncertainty related to the drilling fluid density to drill the interval. It was expected to start with a midrange density, but the operator expected partial to severe losses while drilling the ˜2,624 ft [˜800 m], highly fractured limestone interval. Mud losses generating NPT and extending the time to drill the section was a major concern. Mud lost to the formation using the proposed drill plan was 1,357.9 bbl [215.9 m³].
