DEPARTMENTS AND COMMENTARY ABOUT THE COVER The industry is investing more in advanced drill bit tech-nology, resulting in savings on overall project costs (Inset photos courtesy of Varel,Drillformance, NOV ReedHycalog, Baker Hughes, and Halliburton). Meanwhile, opera-tors in West Africa are looking west as they anticipate presalt riches analogous tothose offshore Brazil. (Photo courtesy of Tullow Oil; cover design by Laura J. Williams) COMING NEXT MONTH The April issue of E&P  takes a close look at risk ownership, manage-ment, and mitigation as it applies to the upstream oil and gas industry and offers suggestions for improv-ing exploration success and exploring in frontier regions. Land rig advances, subsea technology, andservice and supply vessels also receive special attention. Regional features include the Haynesvilleshale and India. As always, while you’re waiting for the next copy of E&P  , remember to visit  for news, industry updates, and unique industry analysis. Printed on recycled paper The LOW PRESSURE AUTOCHOKE CONSOLE* (LPAC*) unit gives precise bottomhole pressure control during MPD and UBD drilling operations - keeping you in the pressure stability window. Dig ital touch screeninterfaces located in the driller ' s cabin and rig floor offer greater coordination during pressure-critical operations . With simultaneous high-resolution monitoring and direct pressure control of our unique AUTOCHOKE * unit , you gain greater operational performance and efficiency. During the underbalanced drilling of a series of laterals , the system doubled overall R0P from 15 to 30 ft/hr and held the required surface pressure of 350 psi during connections . As a result , the operator cut drilling time by 10 days , saving $1m. Mi SWACO A Schlumberger Company www.miswaco . O °1
