OSTI ID:6339835
Of the approx. 600 wells drilled in the Giddings field, Austin Chalk trend in the last year, most were probably completed by cross-link gel fracs or slick water fracs. Although open hole completions are not uncommon in the chalk, they are not really practical in most situations, given the 600 to 800 ft of gross pay usually encountered in the Austin Chalk trend. Most of the open hole completions occur when an operator takes a kick while drilling and decides to drop a mud pill over the zone, run casing above it, cement it in and produce the interval open hole. Chalk wells are subject to kick at any time during drilling because of natural fracturing systems throughout the trend. Mud weights are generally fairly light for faster drilling, approx. 9.4 to 9.8 lb, depending on the particular area.
