The Saladin Oil Field is located immediately east of Thevenard Island, 25 km northwest of Onslow, in the Barrow Sub- basin, northwest Australia. Saladin 1, drilled in 1985 on a structure mapped from 1984 and older seismic data, tested 47° API oil at 875 kL/d (5510 B/D) from the Early Cretaceous Barrow Group. Additional shallow- water seismic was shot in 1985 and a Telseis* survey conducted in early 1986 over Thevenard Island and its fringing shoals. Saladin 2 in 1986, and Saladin 3 in 1987, tested at 1745 and 1790 kL of oil per day respectively (10 975 and 11 280 BOPD), setting successive Australian single- zone flow records. The fourth well, Saladin 7, was drilled in 1988 on a 1987 seismic line and tested at 1720 kL of oil per day (10 820 BOPD).The oil occurs in southeast- dipping Barrow Group sands overlain by and upthrown against Muderong Shale across the northeast- trending Saladin Fault. The Barrow Group sands have porosities around 24 per cent and permeabilities averaging 5- 6 darcies. Some claystone layers are present, and carbonate cement reduces porosity but less so permeability in parts of the oil column. A bioturbated sand has low permeabilities due to clay burrow- linings.Oil- in- place is currently estimated at 11 MkL (70 MMBBL). Field development will involve offshore platforms and deviated wells from Thevenard Island, on which oil storage and treatment facilities will be placed, and an offshore loading terminal for tanker transport. First oil production is scheduled for mid- 1989.

Iagifu-Hedinia oil field was discovered in 1986 in the remote Highlands of PNG following a multi-year exploration effort. Exploration and subsequent field development of PNG's first petroleum export project were carried out without the aid of seismic data due primarily to the intense karst development in the area. Because of historically low oil prices and the remote and difficult environment, the decision to develop the field did not occur until late 1990. First oil was produced in June 1992, with successful development dependent upon an intense focus on cost management, land owner and government relations, and most critically an early commitment to active reservoir management by an empowered and multi-disciplinary reservoir management team (MDRM team). This MDRM team added as much as an incremental 70 MMBBL oil and US$240 million of net present value to the project. This resulted from its being given responsibility for reservoir characterisation, reserve estimation, economic analysis, and active reservoir management. At its core the team consisted of both petroleum engineers and earth scientists, but incorporated numerous other disciplines as they were needed. Key to this success was the support and endorsement of management to a truly empowered team.

Offshore Oil

A deepwater Spar Drilling Production Storage Offloading (SDPSO) floating system or Spar FPSO that integrates Spar dry-tree production, oil storage and offloading has been proposed for offshore oil exploitation. Benefits of the deep drafted first generation classic Spar, such as excellent stability and hydrodynamic performances that allow dry tree drilling and production, large capacity of the mid hull section for oil storage, cost efficiency for construction and save in-service operations, are combined to provide a competitive solution from moderate deep water of 300m to ultra-deep water of 3,000m. The present Spar FPSO is proposed for the potential deepwater oil field development in South China Sea. It uses the hull mid-section with large capacity for wet oil storage, utilizing the density difference between the oil and the sea water for wet storage and oil-water displacement in the storage tank. To demonstrate the feasibility and to investigate its hydrodynamic performances of the Spar FPSO, comprehensive experimental investigations, including the in-place model tests in the deepwater offshore basin and the VIM model tests in the towing tank, have been undertaken. For the in-place model tests, both the stand alone and the tandem offloading conditions were considered. The classic Spar hull, the taut mooring system and the top tensioned risers (TTRs) were all included to represent the coupling effects of the whole system. Various metocean environments, such as the 100-year storm, the 1-year storm and the offloading condition, were considered to give a complete assessment. Different mooring configurations were also studied to adapt to the deep and moderate water depths correspondingly. The global responses, such as the hull six degree of freedom motions, top tensions of mooring lines and risers, possible green water occurrences, were monitored and recorded in real time. Additionally, a preliminary VIM experiment was also carried out in the towing tank since the vortex induced motions (VIM) is one of the most concerned issues for the deep drafted Spar. The VIM characteristics with different heading angles and current velocities were obtained. It is demonstrated that the Spar FPSO has satisfactory hydrodynamic and VIM performances in metocean environmental conditions in South China Sea. It gives a feasible and competitive alternative with integrated dry-tree drilling, production, oil storage and offloading functionalities for offshore oil field development in deep water depth.
