An operator drilling the upper Meramec formation in Blaine County, Oklahoma was having trouble completing the 8 3/4 in. lateral in one run. The lateral formation consists of interbedded siltstone and limestone rock with numerous zones, and the operator also frequently encountered high-strength stringers as well as chert and dolomite. Crossing these zones commonly caused vibrations and bit-damage. Additionally, previous runs demonstrated that even small amounts of wear on the cutting structure of the bit could lead to dramatic decreases in drilling speed, often prompting the operator to trip out for a replacement bit.
