PetroTeach offers this unique two-day course focused on determining the Reservoir Initial State for reservoir simulation. Hydrocarbons accumulate in reservoirs and typically remain in equilibrium for long periods before production begins. The first and most critical step in reservoir simulation is accurately defining this initial equilibrium state within the simulation model. This course provides a structured and practical approach to determining and implementing the reservoir’s initial conditions. The program serves as a step-by-step guide to understanding, analyzing, and preparing the data required to define the reservoir initial state. It is divided into three main parts, each addressing a key component of the initialization process.

The first part focuses on reservoir pressure data, including data quality control, validation, interpretation, and integration of pressure measurements from multiple sources to establish the initial pressure distribution for the model.

The second part addresses contact level determination integrated with pressure analysis. This includes the evaluation of single, multiple, tilted, and atypical fluid contacts, ensuring accurate representation of fluid distribution within the reservoir.

The final part covers the complete dataset required for initializing a reservoir simulation model. This includes reservoir pressure, fluid contact levels, capillary pressure at contacts, and fluid properties such as API gravity, fluid ratios, saturation pressure, and compositional variations with depth. By the end of the course, participants will be equipped to confidently define and validate the reservoir initial state for reliable simulation results.
