EngineeringPartners International August26,2011 BLOWOUTPREVENTERMACONDO AppendixB: DeepwaterDrilling 1 Deepwater drilling has been commonly known historically as the process of conducting oil & gas exploration and production operations in seawater depths of more than 500 feet (“ft”). Using this definition, there have been approximately 600 Deepwater wells drilled in the GoM.2 Oil production in water depths exceeding 6,000 ft is currently taking place in different parts of the world.3 New explorations in ultra-Deepwater drilling operations are being performed in water depths exceeding 9,000 ft.4 Deepwater drilling presents unique technical and safety challenges, especially for the BOP. At these depths, the BOP equipment, hoses, and connections cannot be reached, except by Remote Operated Vehicle (“ROV”). ROV operations are difficult due to water pressure, lack of visibility, depth perception and color (everything is monochromatic), lack of appropriate tools and the limitations of remote control. In addition, the BOP cannot easily be brought to the surface even when the well is shut in, especially when the well is flowing. When the BOP malfunctions, repair or replacement becomes difficult, if not impossible. Accordingly, planning for Deepwater drilling BOP strategies must be undertaken with the utmost care and prudence. SINTEF published a reliability study on behalf of the MMS, to review subsea BOP performance, entitled Deepwater Kicks and BOP Performance dated July 24, 2001.5 The study reported a total of 117 BOP failures and 48 well kicks were recorded in the 83 wells observed between 1997 and 1998.6 Of the 83 wells, 58 wells were deemed “exploratory drilling”, defined as drilling in less well known formations. Macondo was an exploratory well.7 The report indicated that many of the GoM Deepwater wells were high pressure/high temperature
