Cellular tendon design expands the envelope of water depth and payload on TLPs and enables their use for ultra-deepwater developments as well as production hubs. Cellular tendon design was initially introduced to the industry at OTC Brazil 2013 where

We develop a new space-domain wavefield extrapolation technique for subsurface imaging in heterogeneous elastic media. Unlike the existing space-domain techniques, which separately propagate pressure and shear waves, the proposed method simulates one

We develop a new class of absorbing boundary conditions (ABCs) to prevent unwanted artifacts and wraparounds associated with aperture truncation in migration/modeling using high-order, one-way wave equations. The fundamental approach behind the propo

We develop a new scalar migration technique that is highly accurate for imaging steep dips in heterogeneous media. This method is based on arbitrarily wide-angle wave equations (AWWEs) that are highly accurate space-domain one-way wave equations and

Accurate multiaxial characterization of asphalt concrete requires a thorough understanding of its anisotropic behavior. For that purpose a study has been conducted to examine the anisotropic properties of asphalt concrete in the linear viscoelastic r

Often the requirements for dry—tree completion, direct vertical access (DVA) to production wells, as well as the ability to perform drilling and work-over from the production platform, due to operational, economic, or reservoir requirements, necess

Abstract This paper presents an innovative design for a disconnectable dry tree semisubmersible floater for use in harsh environments and which could be exposed to the threat of iceberg impact. The use of dry tree Top Tensioned Risers (TTRs) in well

The tension leg platform (TLP) is an ideal choice for supporting dry trees in deepwater, mainly due to its favorable motion characteristics and limited stroke requirement for riser tensioners. However, as the developments move into the ultra-deep wat
