2006-2007: “Drilling with Casing - What it Can and Can't Do for an Asset”

Tommy Warrant, Director Casing Drilling Research and Engineering for Tesco, presented “Drilling with Casing - What it Can and Can't Do for an Asset” during the 2006-2007 Society of Petroleum Engineers Distinguished Lecturer Series. About the Lecture Drilling with casing, an emerging technology for simultaneously drilling and casing a well, is gaining increasing acceptance in onshore applications where entire wells are drilled with casing and offshore applications where it is used to drill selected intervals. This talk reviews the current status and advantages/disadvantages in drilling more than 1,000 intervals ranging from shallow surface holes using 20-in. casing to greater than 15,000 ft with 3-½-in. casing.
