What is the purpose of history matching?

What is the purpose of history matching?

What is History Matching? History matching is the process of building one or more sets of numerical models (representing a reservoir) which account for observed, measured data. During any kind of model calibration process such as this, it is important to note that: Reservoir models are models, not reality.

What is assisted history matching?

In assisted history matching (AHM), the simulated dynamic data is compared to the historical data by means of a misfit function. This procedure can be translated into an optimization problem in which the misfit function is an objective function and the optimization problem is bounded by the model constraints.

What is history matching in oil and gas?

History matching is defined as the act of adjusting a model of a reservoir until it closely reproduces the past behavior of a reservoir; this is a common practice in oil and gas industry in order to have reasonable future predictions.

What are the main objectives of reservoir performance analysis?

The main objective of reservoir performance analysis is to solve an inverse problem by matching historical production and properly quantify forecast. We need to properly populate static models to estimate the original oil in place.

What is reservoir simulation technique?

Reservoir simulation is an area of reservoir engineering in which computer models are used to predict the flow of fluids (typically, oil, water, and gas) through porous media. The field of deposits and deposits is a system of quantitative ideas about the process of extracting oil and gas from the subsoil.

What is reservoir analysis?

Reservoir analysis develops subsurface data to integrate analysis of rocks, pores, and fluids from various reservoirs. In addition, it calculates dynamic rock & fluid properties and gives reservoir model indirect measurements.
