Abstract
Methods for drilling and treating for lost returns continuously while drilling are provided. High fluid loss drilling fluid is used, along with particulate material that forms an immobile mass in hydraulic fractures to prevent their growth. The particulate material may be selected based on the predicted size of a hydraulic fracture, based on particle size to minimize fines, based on specific gravity to attain high solids content for a selected fluid density, and/or based on permeability of the particles to attain a high spurt loss.
