The tutorials in this section address the calibration procedure/history matching for different types of reservoir fluids (gas, oil, retrograde condensate). Single and multi-tanks models are discussed in this category.
Performing the history matching for a gas reservoir – MBAL
This introductory tutorial will guide the user how to perform a history match for a gas reservoir and obtain useful information such as the GIIP, drive mechanism, etc.
Performing the history matching for a gas and condensate reservoir – MBAL
The history matching of a gas and condensate field is performed in this tutorial. In this case, production information is available on a well-by-well basis. OGIP and acquifer parameters are obtained.
Performing the history matching and predictions for an oil reservoir – MBAL
In this tutorial, an oil reservoir is analyzed. The pressure trend is history matched and OOIP is obtained. Then, production forecast is set using well models to evaluate production rates; estimating recovery factor and future Reservoir Pressures.
This introductory tutorial guides the user through the creation and matching of a Tight Gas well model. Well production data is input to the model and then the reservoir parameters (GIIP, permeability and drainage area) are matched.
Tight gas well modelling in MBAL (Fractured well) – MBAL
This tutorial shows how to match a Fractured Tight gas well in MBAL, using production data. Tight Gas Type curves are used to perform the adjustments and evaluation of OGIP and reservoir parameters such as permeability and drainage area.
Black Oil Condensate model validation procedure – MBAL
In material balance, using black oil PVT models for retrograde condensate gases is not always possible. This tutorial outlines the various validation checks needed to be done, and how results should be compared between the compositional (model using EOS) and the black oil model.
History Matching of a Single Layer Multi-Tank Reservoir using Material Balance – MBAL
Areal differences in reservoir pressure can be modeled using multi-tank approaches. In this case, a single gas layer is modeled using three separate tanks. The individual GIIP and the transmissibility values between the tanks are evaluated.
History Matching of a Multi-Layer Reservoir using Material Balance – MBAL
A gas and retrograde condensate field, producing from three wells, is modeled using material balance. The four productive layers aren't communicated to each other. The history matching procedure is performed using the OGIP as a regression variable.
A newly discovered gas reservoir is modeled using MBAL in this tutorial. Quick production forecasts and development plans are outlined (number of wells, compression pressure, etc).
Constructing and matching a material balance model for an oil field – MBAL
In this tutorial a review of the material balance history matching for an oil system is reviewed. This tutorial will guide the user through the different steps to calibrate and history match a material balance model.
