Deepwater Well-control Aspects For Slender-well Drilling

, 2015
The 2003 Brazilian deepwater drilling record was achieved with a slender well in 9,475-ft water depth in Campos basin. The well was drilled safely with a surface-blowout-preventer (SBOP) system. The full-length paper details two discussions. The first is

Drilling Riser System Analysis for Ultra-deepwater

, 2016
Master해양 시추기술의 발달과 더불어 시추가능 수심 또한 깊어져 왔다. 1897년 캘리포니아 서머랜드에서 시작된 35 ft 수심의 시추기술은 현재 초심해인 12,000 ft까지 시추가 가능하도록 발전됐다. 최근 15,000 ft 수심, 20k psi 유정압력 사양의 시추선 개발이 새로이 각광을 받고 있으며, 실제로 오일 메이저 사(社)와 조선소, 그리고 장비 제작업체간의 협력을 통해 차세대 시추설비의 개발 초기단계에 있다.
