Future Exploitation Strategy Using Integrated Subsurface-to-Surface Methodology: Field Case Study—Litoral De Tabasco Asset

摘要

In reservoir development studies or exploitation studies for a hydrocarbon producing field, it's necessary to go through different stages, from visualization to planning all involved activities. In visualization we must consider basic factors that will contribute to an optimal exploitation plan. Thus we need tools capable of integrating the whole system, from subsurface production all the way to the surface. Different subsurface productivity techniques, production methods, secondary recovery projects, facilities required, among others are the fundamental base for an adequate reservoir exploitation planning, considering all limitations within the system as well as related costs. In this study, it's considered the analysis done for Field Exploitation for Litoral de Tabasco Asset (AILT), which comprises 14 hydrocarbon fields and all related production facilities of Region Marina Sur Oeste (RMSO). Different analysis techniques were applied such as: material balance (MB), nodal analysis (NA), simulation of multiphase gathering systems, statistics, integrating all this disciplines in a network to evaluate production scenarios for 15 years, considering production forecasts, pressure drops along the system and Asset production facilities limitations and needs. The integrated model will allow determining the optimal option according to the evaluated scenarios and facilities needs along the productive life of all analyzed fields.
