Abstract
Modified Drilling fluid compositions, lost circulation material compositions and methods for using drilling fluid compositions are provided with enhanced loss control properties where the modified drilling fluid may include a carrier fluid, one or more drilling fluid additives, and a lost circulation shape-adaptable material. The loss lost circulation shape-adaptable material may include a plurality of oval shaped composite particles, wherein the plurality of oval shaped composite particles comprise a first component, a second component, and a high temperature, high pressure (HTHP) binding adhesive. Methods to control lost circulation in a lost circulation zone in a wellbore may include introducing a modified drilling fluid into the wellbore such that the modified drilling fluid contacts the lost circulation zone.
