Well control professionals focused on use of shear blind rams (SBR) with surface stack BOPs during the IADC Middle East Regional Well Control Roundtable, which directly followed IADC Well Control Middle East 2008 on 4 December. Two dozen well control professionals attended the roundtable, held 4th December at the Grand Hyatt Hotel in Muscat, Oman. Attendees hailed from Oman, the United Arab Emirates, Saudi Arabia, Libya, Qatar, Singapore, the US and the UK.

Led by Paul Sonnemann of Chevron, the discussion centered on individual company practices regarding the placement, intent, and consequences of using shear-blind rams with surface BOPs.

Potential considerations identified outlet configuration, design purpose, bypass sequence and control system sizing, ram locks, well design, avoiding inadvertent shear, shear capability testing and closing ratio listings.

Chevron is currently studying the use of SBRs to determine the necessity of establishing practices for uniform use of SBRs and potential ramifications on well design.  The discussion revealed wide variances in practice and philosophies among different companies. Mr. Sonnemann suggested the topic be explored further, possibly in a panel discussion at an IADC Well Control Conference.

Ed Ramsay of Drilling Systems UK provided an introduction to the IADC Well Control Committee’s new Simulator Subcommittee.  Mr. Ramsay gave the presentation on behalf of Subcommittee Chairman Steve Vorenkamp of Wild Well Control.

The purpose of the subcommittee is to seek industry input on potential ways to improve well control simulator modeling and performance, and techniques to enhance their effective use as training tools.

Other topics discussed included new WellCAP instructor qualification requirements recently adopted by the IADC Well Control Committee. The new requirements, to be implemented in 2009, will impose hourly instruction minimums and other requirements on applicants seeking approval as new WellCAP instructors.  The requirements also include guidelines that existing instructors must follow for continued requalification.

Another discussion topic Shell’s recent inclusion of IADC’s WellCAP program in its official well control manual.

Well Control Roundtables are designed to provide informal forums for discussing well control topics of interest or expanding on topics discussed at IADC Well Control Conferences.  Those present urged IADC to continue to hold such meetings in conjunction with its Well Control Conferences.  IADC will hold two such conference in 2009: IADC Well Conference of the Americas in Denver on 25-26 August, and IADC Well Control Asia Pacific 2009 in Bangkok on 18-19 November.
