Evaluation of the applicability of subsea wellheads running by jack up rig for oil and gas exploration projects in shallow water, offshore Vietnam

Abstract: An overview of the oil and gas production in Vietnam reveals that certain major oil and gas projects, which account for large-scale operations and dominate the oil and gas production in the continental shelf of Vietnam, are entering a declining production phase. This affects not only the efficiency of individual projects but also the national energy security. Consequently, the research and application of new technical solutions to supplement and maintain oil and gas production become the most critical tasks in the current phase. However, based on the assessment of oil and gas potential in the basins on the continental shelf of Vietnam, few major offshore oil and gas prospects can be developed using conventional methods to achieve high economic efficiency. Therefore, two development concepts with the highest feasibility, both economically and technically, are: the development of marginal fields in shallow water conditions and the execution of exploration/production activities in new prospects at existing production projects by drilling additional infill wells and connecting them to the central processing platform (CPP).The article evaluates the potential and proposes a solution using subsea wellheads & X-mas tree, operated by jack-up rigs, to develop marginal oil and gas fields in shallow water conditions and existing oil and gas fields with potential prospects located far from the CPP. This approach aims to reduce operational costs and enhance the overall efficiency of the project.
