Offshore fixed platforms and wellhead platforms are the main elements of Vietsovpetro JV fields development on the shelf of Vietnam. These facilities gather and treat the oil coming from production wells, which is then supplied through the underwater pipeline systems to the floating storage and offloading units. Field development by means of wellhead platforms and central processing platform helps avoiding significant capital investments in construction of metal-intensive fixed platforms with a multifunctional top structure and reduces operating costs. The development vector of the Vietsovpetro JV in the area of capital construction is aimed at reducing metal consumption and costs. Optimization of construction solutions and transition to unmanned technologies for operating wellhead platforms led to cost reduction by more than half compared to 2014. Currently, the priority offshore structures in the Company are the unmanned wellhead platforms and satellite platforms. The introduction of unmanned wellhead platforms and satellite platforms benefits in optimizing the company's capital costs, however further minimization of the investments for construction of new wells on existing platforms during the late development stage, requires additional non-standard approaches. One of such solutions is the organization of additional wells at existing offshore structures. The article covers the issues related to designing and construction of new additional wells on the operating facilities, which have not been considered by the initial standard design. The implementation of an integrated approach to improving the efficiency of offshore field development at the Vietsovpetro JV allows the company to maintain its leading position in the Southeast Asia.
