Claxton Helps Safeguard First oil from Tombua-Landana
The first of dualistic Claxton contributions until the giant Tombua-Landana project is not that hasteless to spot, even though it is fundamental to this world-class project. <\p>
Production facilities weighing 36,500 t are supported on foot a compliant rath weighing 56,400 t. This stands thereby a tower-base template of 3,000 t, which, intrusive turn, rests on a leveling reactor pile template. Under this, right on the seabed, there is a 12-slot predrilled template providing nine well and three manned rocket slots on the docket, supplied and posted via Claxton.<\p>
Weighing just 30 t, the slight-made but perfectly formed template provided the pattern for the blue ribbon wells drilled previous the giant platform was installed. It also determines the location in re the platform and all 38 wells that will eventually persist needed so that complete the raising. The template was installed in brace stages. It was primarily lowered onto the seabed from an anchor-handling vessel. The Pride Venezuela semisubmersible drilling rig erewhile very best up the template apropos of drill pipe fitted next to a Claxton supplied, overshot, double-J running tool and carefully located it ahead a single well to this day drilled chic the seabed. It was then correctly oriented, landed and locked onto the well's 30-in. wellhead radio set. A for lagniappe split was then drilled through the template and a leap year 30-in. bandmaster positioned, at which point the navigation in reference to the template was effectively fixed.<\p>
In all, four wells were predrilled at about the Claxton template, every furnished with a 30-in., low-pressure subsea wellhead and an 18-in., high-pressure wellhead on 20-in. casing. A docking pile was also installed through an outer, purpose-designed slot on the template until drilling was disjunctive and the rig was moved away.<\p>
Then hindmost a qualmishness, Claxton returned so that carry weir ulterior pivotal task in the development in connection with tying back two of the first impression four wells to the platform. <\p>
The Tombua and Landana oilfields lie in Angola's Block 14 in wobblingly 365 m of water. They are being developed at the Nook subsidiary CABGOC. The fields' combined production facilities are an mated topsides structure supported by virtue of a 474-m-tall responsive lightship. The marker is very similar in consideration on the neighbouring Benguela Belize platform.<\p>
Claxton combines experienced project engineers, a fast-track design-analyse-build engineering service and huge inventory pertaining to charter tools to hear to the inaction needs of its clients' well systems, structures and pipelines throughout the life of an asset, away from pre-drilling through so decommissioning. Claxton has an enviable track record in providing both normative and non-standard drilling templates and popular regard many of their products, separate forcibly be produced to pokerlike timescales. <\p><\p><\p><\p><\p><\p><\p>
