Since its usage began, horizontal drilling has offered dramatic reservoir-exposure improvements, Lately, a new trend has developed toward drilling multiple laterals, thus further increasing production. Until recently, laterals typically were not cased and tied back, which meant when workovers or cleanouts were required, re-entry was difficult and completions were virtually impossible. Now, proven technology allows multiple laterals to be cased and tied back. Developed by Sperry-Sun Drilling Services, a Dresser Industries Inc. company, the proprietary Lateral Tie-Back System (LTBS) allows multiple laterals to be drilled out of any well profile planned to include an LTBS installation. Multilaterals may be drilled into predetermined producing formation quadrants at any time in the productive life cycle of wells and can be used in vertical, directional or horizontal applications. This article will discuss LTBS applications and the four interacting system components, along with case histories.
