a retrospective of oil and gas field Development in the u s outer continental shelf gulf of mexico 1947 2017
Natural resources research, 2019Co-Authors: Mark J Kaiser, Siddhartha NarraAbstract:The U.S. Gulf of Mexico is a world-class hydrocarbon basin and industry has an impressive track record of advancing its capabilities in the region. From 1947 to 2017, the U.S. Gulf of Mexico has produced over 52 billion barrels oil equivalent in federal waters, 20.7 billion barrels of oil and 187 trillion cubic feet of natural gas. Remaining reserves are estimated at 4.8 billion barrels oil equivalent, 80% of which reside in deep water greater than 400 ft. Undiscovered technically and economically recoverable resources are estimated at 74 billion barrels oil equivalent mean potential, 85% of which are estimated to reside in deep water. In this retrospective of exploration and production in the U.S. Gulf of Mexico, a statistical and trend analysis of field counts, sizes and distributions are presented followed by exploration and Development Drilling activity. Field discovery rates, play types, and reserves are summarized along with a description of the geology of the shallow water and deep water U.S. Gulf of Mexico and remarks on reserves growth. Every decade or so, a new concept, play type or technology has emerged in the region, and most resource potential occurs in areas requiring technical advancement.

Deepwater gas kick simulation
Holanda, 2015Co-Authors: Cs Avelar, Pr Ribeiro, Sepehrnoori KAbstract:Important gas and light oil reserves have recently been found in the Tupi field of Santos Basin. Brazil. The Tupi is formed by subsalt hydrocarbon reservoirs 6000 to 7000 m deep, with water depths up to 3000 m, subjected to high pressure and high temperature bottomhole conditions. The investigation of well control aspects during exploratory and Development Drilling in that field requires kick simulators that can handle the pressure and temperature range encountered in deep and ultra deepwater scenarios. Safety issues associated with well control situations demand precise predictions of wellbore pressures and liquid/gas volumes as well as flow rates at the surface. The possibility of blowout occurrence needs to be mitigated in order to avoid human casualties, financial losses (production stop and equipment losses) and environmental damage. Several kick simulators have been developed during the last four decades in order to address well control problems during the Drilling operation. The simulators have an important mission that involve: i) helping the Drilling engineer to make decisions during well control procedures and kick situations, ii) personnel training and certification and iii) better understanding and interpretation of field observations. The evolution of the codes has been driven by the increasing challenges in exploration and Development of the remaining hydrocarbon reserves. Increasing complexity of well geometry (diameters and trajectory), well location (land and offshore) and bottomhole conditions (increasing pressure and temperature severity with depth) has required more precise two-phase flow models and more representative rheological as well as compositional models. This work presents the mathematical modeling of a proposed gas kick simulator, the comparison between simulated and measured results for a test well located in Brazil. and a sensitivity analysis regarding the effect of water depth in well control parameters.

effects of the terra nova offshore oil Development on benthic macro invertebrates over 10 years of Development Drilling on the grand banks of newfoundland canada
Deep-sea Research Part Ii-topical Studies in Oceanography, 2014Co-Authors: Michael D Paine, Elisabeth M Deblois, Bruce W Kilgour, Ellen Tracy, Patricia Pocklington, Roger D Crowley, Urban P Williams, Gregory G JanesAbstract:Abstract This paper describes effects of Drilling with water and synthetic-based Drilling muds on benthic macro-invertebrates over 10 years at the Terra Nova offshore oil Development. As such, the paper provides insight on the effects of relatively new synthetic-based Drilling muds (SBMs), and makes an important contribution to our understanding of the long-term chronic effects of Drilling on benthic communities. The Terra Nova Field is located approximately 350 km offshore on the Grand Banks of Newfoundland (Canada). Sediment and invertebrate samples were collected in 1997 (baseline) prior to Drilling, and subsequently in 2000, 2001, 2002, 2004, 2006, 2008 and 2010. Approximately 50 stations were sampled in each year at distances of less than 1 to approximately 20 km from drill centres. Summary benthic invertebrate community measures examined were total abundance, biomass, richness, diversity and multivariate measures of community composition based on non-Metric Dimensional Scaling (nMDS). Decreases in abundance, biomass and richness were noted at one station located nearest (0.14 km) to a drill centre in some environmental effects monitoring (EEM) years. These decreases coincided with higher levels of tracers of drill muds in sediments (barium and >C 10 –C 21 hydrocarbons). Abundances of selected individual taxa were also examined to help interpret responses when project-related effects on summary measures occurred. Enrichment effects on some tolerant taxa (e.g., the polychaete family Phyllodocidae and the bivalve family Tellinidae) and decreased abundances of sensitive taxa (e.g., the polychaete families Orbiniidae and Paraonidae) were detected to within approximately 1–2 km from discharge source. Lagged responses three to five years after Drilling started were noted for Phyllodocidae and Tellinidae, suggesting chronic or indirect effects. Overall, results of benthic community analyses at Terra Nova indicate that effects on summary measures of community composition were spatially limited but, as seen elsewhere, some taxa were more sensitive to Drilling discharges.
