Hyperbaric Excavation: New Insights and Simulation Tools

Boomsma, Wiebe (IHC Mining) | Grima, Mario Alvarez (IHC MTI) | Los, Jan (IHC MTI)

OnePetroMay, 2016

This paper addresses the Royal IHC research program concerning the effect of high hyperbaric pressure on rock cutting forces and power requirements. An overview of the rock cutting experiments conducted in a hyperbaric tank in Brest, France is summarized. The results of the experiments along with the hyperbaric cutting model developed so far have been used to create our in-house software ‘Gibraltar’. Examples of simulations results with the software are shown. Current research on numerical methods and lab experiments conducted so far are mentioned as well as possible research directions in the near future. It can be concluded that ‘Gibraltar’ is in fact a generic and flexible framework, a universal world in which additional tools and excavation knowledge may be added and it has already been used to design some of the future excavation tools of Royal IHC, showing his added value.

Girassol: Subsea Well Completion Experience

Thane, Larry (Total Fina Elf E&P Angola) | Lassus-Dessus, Jean (Total Fina Elf E&P Angola) | DeLaporte, Dominique (Total Fina Elf E&P Angola)

OnePetroMay, 2002

Abstract On the Girassol project, an integrated project team was responsible for subsea well completions from conceptual design through to installation. This paper summarizes experiences to date with equipment delivery, installation and early operations including production start-up. Future developments and challenges are discussed with a focus on subsea aspects of well completions. Non-productinve time (NPT) results are presented and analyzed. Examples are given of specific successes and problems. Introduction A project life-cycle (Life of Field) approach was taken for Girassol subsea well completions. This approach required consistency and continuity through all project phases: equipment delivery, installation and operations. Trade-offs between these phases must be evaluated and managed. Subsea well completion equipment and services was supplied as part of a comprehensive lump-sum contract for the Girassol subsea production system (SPS). This SPS package consisted of subsea well equipment (including tooling packages), subsea manifolds, production control systems, workover control systems, and tree-to-manifold jumpers. Conceptual equipment design was the result of a design competition between four major subsea contractors. Following this design competition, the winning contractor was selected as supplier for the entire SPS package. Major adjacent, ie interfacing with SPS, contract packages proceeded in parallel with the SPS contract.Drilling rigs (RIG). Downhole well equipment (WELL). Umbilical and flowline (UFL). Floating, production, storage, and offloading (FPSO). This approach, parallel engineering and manufacture of all contractual packages, was a consequence of the "fast-track" development strategy adopted for Girassol. Total time from SPS contract award to installation of first subsea Xmas tree was 32 months. First oil production was achieved 13 months later. Actual delivery of first xmas tree was 12 months later than planned. This "fast-track" approach posed unique challenges for managing interfaces between contract packages. The geographical spread of project participants accentuated this challenge. The SPS team was based in Kongsberg, Norway, during equipment design and construction. Subsea well equipment was manufactured, assembled, and tested in Kongsberg and Dunfermline, Scotland. During this time, the drilling team, which was also managing the rig construction, was based initially in Paris, France, and later in Luanda, Angola. The rigs were being constructed in Korea and Brest, France. UFL and FPSO teams were based in Paris. Downhole equipment was manufactured in USA and UK. The physical location of the Girassol field presented special challenges for subsea well completions. The wellheads are installed in average water depths of 1,400 m, which imposed many design constraints and priorities. The remote location of Girassol, added to the fact that this was the first major subsea development offshore Angola, meant that support capabilities - onshore base, logistics, engineering, spare parts, machine repair, etc - were either distant or had to be established in Angola. Management of rig NPT during well completions was a critical project objective. This objective drove many strategies, starting from design and continuing through construction and installation.

Equipment for Mechanized Running of Tubulars on a Fifth-Generation Semi Submersible—Commissioning and Field Experience

Kinzel, Holger (Weatherford Oil Tool GmbH) | Peyon, Albert (Transocean Sedco - Forex) | Lorenz, Joerg (Weatherford Oil Tool GmbH)

OnePetroSeptember, 2000

Abstract Despite the downturn in the industry, a new generation of Semi Submersibles has been developed and put into operation. This so called fifth generation of Semi Submersibles has ambitious goals in regards to operational safety and efficiency. The rig concept includes new ideas on how to make-up and run drillstring components, riser pipe as well as casing and tubing. Doubles, Triples or even Quadruples of pipe are being made-up at special "Mouse-hole stations" including their own mechanized handling and make-up equipment. By this means, many functions such as prefabrication of stands of risers, drill pipe and casing stands can be carried out offline without interrupting or delaying drilling operations. Considerable time- and cost saving is anticipated. The paper describes the planning, development and implementation of the modular concept of the PowerFrame carrying the fully remote controlled power tongs that were installed on three of those rigs built in Brest/France and in Singapore. Actual field experience from a drilling location was not available when this paper was written (May 2000), as the first rigs are scheduled to arrive on location by June 2000. However, during the commissioning sufficient experience was gained to allow the prediction that the ambitious goals set in regards to time saving will be achieved. 1 Project Description Most rig building activity is led by long-term targets that are not very much affected by short term variations in the daily oil price and the related variations in drilling activity. Many new offshore rigs are built for deepwater conditions, specified by a water depth of at least 3,500 ft in that the rigs are operating. The new challenges of drilling on those water depths require completely new concepts to cut down the well costs to an economically acceptable limit. The costs of a well is directly related to the daily costs of the rig, but of course also to the duration of the drilling operation necessary for each well. To complete a well requires the task of actually drill the well, with the rate of penetration being the important factor to determine the time it takes to reach a certain depth. The second factor are the flat curves in the drilling progress curves where no further depth is reached, due to activities such as tripping, logging or running casing and cementing. A "new generation" of floating rigs must therefore follow new guidelines and procedures to be able to reduce costs [1]. The Sedco Express rigs (Fig. 1) are a new type of floater that make use of measures to reduce both, drilling time as well as flat time. Drilling time is reduced, for example, by specifically designed, strong mud pumps. Flat times are reduced by a new concept of tripping as well as riser pipe and casing handling, that includes the mechanized handling of pipe as well as automated make-up of all threaded connections. The ambitious goal of these measures is to reduce the total time on location by 25%, and associated well construction costs by 30%. Three of these rigs were built, respectively are currently under construction; the Sedco Express and the Energy Express in Brest as well as the Cajun Express in Singapore.

The Bismarck Encounter

Garzke, William H. (Gibbs & Cox Inc.) | Dulin, Robert O. (Basic Technology Corporation)

OnePetroOctober, 1993

The authors of this paper have been fortunate to have had the opportunity to assist Dr. Robert Ballard of Woods Hole Oceanographic Institute and the Quest Group in the discovery and analysis of the Bismarck wreck in June 1989. Although we did not participate in Dr. Ballard's expedition aboard the Star Hercules, we gave advice and counsel to his personnel and did much of the photo interpretation. We were greatly aided by two of the Bismarck survivors, former German Ambassador Baron von M(Jllenheim-Rechberg (former LCDR, German Navy), the senior surviving officer, whom we assisted in the republishing of his book, and Mr. Josef Statz, who was the sole survivor from the Damage Control Central on the Bismarck[1]. 3 These two men worked tirelessly with the authors and assisted in the preparation of drawings by Mr. Thomas Webb of various views of the damaged Bismarck, which shows her just before her capsizing. These views of the damaged Bismarck were prepared after many hours of intensive study of the videotapes and still photography brought back by Dr. Ballard's team from the wreck site some 15 317 ft below the water surface, 600 miles west of Brest, France. A number of these views have been published in various magazine articles and books [2–5].
