The upstream sector also known as the Exploration and Production (E&P) sector, normally covers the exploration and discovery of sources of crude oil and gas both onshore and offshore. It also covers the drilling of exploratory wells and the operation of these wells to extract the discovered energy source and bring it to the surface for transportation to refineries.
The main physical aspects that can be simulated when building an upstream virtual model are mentioned below.
Reservoir and geology simulation (basin modeling and simulation, well data interpretation, near-well modeling of multiphase flow simulation, utilizing, for example, reservoir simulation software).
Production phase simulation (completion processes, liquid/gas production processes, well distribution systems, etc.)
Subsea systems design and analysis (pipeline lay analysis, simulation and analysis of mechanical-structural components and devices, stress analysis and design of pressure components, etc.).
Offshore structures design and analysis (simulation and analysis of fixed and floating offshore structures, structural verifications and code checks, revamping of existing fixed offshore structures based on the stochastic fatigue approach, simulation and analysis of pressure vessels and pressure components, vessel and pipeline dynamic motion analyses for S-laying or J-laying pipeline configurations).
The downstream sector refers to the extracted hydrocarbons in their liquid form (petroleum) or in their gaseous form (natural gas) being refined and the subsequent distribution of derivative products such as fuels, petrochemicals, lubricants and residuals for use in by-products.
The main physical aspects that can be simulated when building a downstream virtual model include: Heat and mass transfer in distillation columns, heat transfer equipment; Bulk liquid storage structures for both atmospheric and low temperature/cryogenic storage; Pressure drop evaluation; Mist eliminators; Process furnaces; Fluid dynamic analysis of coker and vacuum towers; Evaluation of inlet feed devices to reduce the liquid entrainment and velocity to improve vapor distribution; Understanding of risers, regenerators, and cyclones for the FCC process; Investigation of flow patterns and FSI in horizontal and vertical piping; Flow rate meters/flow meters; Gravitational separators; Petrochemical storage and process vessels; Refinery process units; Petrochemical facilities; Gasification plants, hydrogen generating plants; Equipment simulation optimization.
