This article explores various aspects of flow assurance in subsea developments. Flow assurance is an understanding of multiphase flow fluid dynamics and analyses, an ability to identify flow-related problems using state-of-the-art prediction tools, and the knowledge to develop solutions that eliminate, mitigate or remediate flow-related issues encountered in subsea systems. Flow assurance is reliable, safe and cost-efficient management of hydrocarbons from reservoir to export without any flow-related issues over the life cycle of the oil field. Subsea developments continue to escalate in quantity and complexity as the exploration and production companies ramp up exploration of deep-water and ultra-deep-water reservoirs with complex formations in harsh environments with increased challenges. Some of the technologies under thermal solutions are thermal insulation, direct electric heating and electrically-heated pipe-in-pipe. Oil and gas companies generate revenue from the oil produced. If the oil flow stops, their revenue stops. The more it stops the more they lose cash. Hence it can be termed as cash flow assurance. With fluctuating oil prices and unpredictable production issues, engaging flow assurance at every stage starting with the early phase ensures uninterrupted transportation of reservoir fluid from pore to process facilities in a safe manner and insures cash flow.

Water Problem

Currently the oil and gas industry is focusing on challenging deep water projects, particularly in Campos Basin located coast off Brazil. However, there are a lot of prolific reservoirs located in shallow water, which need to be developed and they are located in area very far from the coast, where there aren’t pipelines facilities to export oil production, in this case is necessary to use a floating production unit able to storage produced oil, such as a FPSO. So, the riser system configuration should be able to absorb FPSO’s dynamic response due to wave load and avoid damage at touch down zone, in this case is recommended to use compliant riser configuration, such as Lazy Wave, Tethered Wave or Lazy S. In addition to, the proposed FPSO for Tubarão Martelo development is a type VLCC (Very Large Crude Carrier) using external turret moored system, which cause large vertical motion at riser connection and it presents large static offset. Also are expected to install 26 risers and umbilicals hanging off on the turret, this large number of risers and umbilicals has driven the main concerns to clashing and clearance requirement since Lazy-S configuration was adopted. In this paper, some numerical model details and recommendations will be presented, which became a feasible challenging risers system in shallow water. For instance, to solve clashing problem it is strictly recommended for modeling MWA (Mid Water Arch) gutter and bend stiffener at top I-tube interface, this recommendation doesn’t matter in deep water, but for shallow water problem is very important. Also is important to use ballast modules in order to solve clashing problems.

Abstract Globally, there are two types of petroleum fiscal system; the concessionary and the contractual petroleum fiscal system. The main differences between the two types of petroleum fiscal system is the ownership of the resources and some distinct fiscal terms. The contractual petroleum fiscal system specifies a cost recovery option and profit oil split unlike the concessionary petroleum fiscal system that allows the contractor to recoup his capital before payment of tax. This tends to increase the risk associated with the host government revenue as investment in the production of hydrocarbon is filled with uncertainties. There is a need to redesign the concessionary petroleum fiscal to enable it reduce the risk associated with the host government revenue by making the host government to earn revenue early from petroleum investment. This research therefore evaluated a hybrid petroleum fiscal system for investment in the exploration and production of hydrocarbon. The concessionary petroleum fiscal system was adjusted to include a cost recovery option. Petroleum economic model for investment in a typical onshore oil field was built using spreadsheet modelling technique with the fiscal terms in the hybrid petroleum fiscal system embedded in it. The cost recovery option and oil price in the model were varied between 0-100% and $20-$100 per barrel. The NCF, IRR and payout period of the investment were determined. It was observed that the lower the cost recovery option, the higher the host government revenue. From the profitability analysis of the investment in the hybrid petroleum fiscal system, it was observed that when the price of oil was $100/bbl, the NCF of the host government was $9146 and $8426.3 for 0% and 80% cost recovery option. The lower the cost recovery option, the higher the payout period and the lower the internal rate of return. Though lower cost recovery increased the host government revenue more but it may make the hybrid petroleum fiscal system unattractive for investment in periods of low oil price. Hence a higher cost recovery option was recommended for the use of this type of petroleum fiscal system.

Petrobras developed a new kind of anchoring device known as Torpedo. This is a steel pile of appropriate weight and shape that is launched in a free fall procedure to be used as fixed anchoring point by any type of floating unit. There are two Torpedoes, T-43 and T-98 weighing 43 and 98 metric tons respectively. On October 2002 T-43 was tested offshore Brazil in Campos Basin. The successful results approved and certified by Bureau Veritas, and the need for a feasible anchoring system for new Petrobras Units in deep water fields of Campos Basin led to the development of a Torpedo with High Holding Power. Petrobras FPSO P-50, a VLCC that is being converted with a spread-mooring configuration will be installed in Albacora Leste field in the second semester of 2004. Its mooring analysis showed that the required holding power for the mooring system would be very high. Drag embedment anchors option would require four big Anchor Handling Vessels for anchor tensioning operations at 1400 m water depth. For this purpose T-98 was designed and its field tests were completed in April 2003. This paper discusses T-98 design, building, tests and ABS certification for FPSO P-50.

<p>Carbonate rocks from the Macaé Group (Albian) represent an example of carbonate sedimentation related to the drift phase in Campos Basin. This study presents depositional features, integrating them with diagenetic and stratigraphic aspects of the Macaé Group carbonates including the upper part of the Quissamã Formation and the lower part of the Outeiro Formation. Macroscopic analyses in cores and microscopic ones in thin sections allowed the recognition of eleven sedimentary facies - nine of them corresponding to the Quissamã Formation and two of them representing the Outeiro Formation. These facies were grouped into five facies associations. Oolitic grainstones and oncolitic grainstones are interpreted to be deposited in shallow depth probably in shoals above the fair weather wave base. The interbanks between shoals were formed in less agitated waters and characterized by deposition of peloidal bioclastic packstones and wackestones representative of sedimentation in calm waters. Bioclastic packstones and oolitic packstones/wackestones represent allochthonous deposits related to the beginning of the regional drowning that occur in upper Quissamã Formation. Pithonellids wackestones and bioclastic wackestones with glauconite are related to deep water deposits, characteristics of the Outeiro Formation. Post-depositional features revealed the action of diagenetic processes as, micritization, cimentation, dissolution, compaction, dolomitization and recrystallization occurred during the eo- and mesodiagenesis phases. Vertical facies analysis suggests shallowing upward cycles stacked in a sequence progressively deeper towards the top (from the Quissamã Formation to the Outeiro Formation).</p>
