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.

What is the purpose of reservoir simulation?

The purpose of reservoir simulation is to predict field performance and ultimate recovery for various field development scenarios to evaluate the effects on recovery of different operational conditions and compare economics of different recovery methods.

What is the difference between reservoir and well?

That block of oil bearing rock is what we call a reservoir. A lot of people use the term reservoir and oilfield interchangeably but both mean a piece of ground containing oil bearing rock. To get the oil out of the rock you must drill a hole down from the surface into the oil bearing rock, That hole is called a well.

What is reservoir technology?

Reservoir engineering is a branch of petroleum engineering that applies scientific principles to the fluid flow through porous medium during the development and production of oil and gas reservoirs so as to obtain a high economic recovery.

What are reservoir properties?

The reservoir rock properties that are of most interest to development geologists and reservoir engineers (amongst others) are Porosity, Compressibility, and Permeability. Porosity is a rock property that defines the fraction of the rock volume that is occupied by the pore volume.

Why is reservoir characterization important?

Reservoir characterization is defined as the model that characterises the reservoirs based on its ability to store and produce hydrocarbons. They are used to indicate the reservoir fluids behaviour under different circumstances and to find the optimal production techniques that are able to maximise production.

What is CMG software?

CMG develops market-leading reservoir simulation software, which is recognized worldwide. as the industry standard for advanced recovery processes. CMG’s superior technology continues to break new ground for capabilities — simulating the simple to the most advanced recovery processes.

What is porosity in reservoir?

Porosity determines reservoir storage capacity. It is defined as the ratio of void space, commonly called pore volume, to bulk volume and is reported either as a fraction or a percentage. (Also see Reservoir quality.)

What is reservoir inflow performance?

Reservoir inflow performance is the reservoir pressure-rate behavior of an individual well. This article discusses the mathematical estimation of inflow performance.

Do reservoirs perform under waterflood?

Reservoir performance under waterflood: Performance of the reservoirs, whether primary, secondary, or tertiary, is greatly influenced by the heterogeneity of the formation. The heterogeneity of rock is attributed to changes in depositional environments and geologic events that occurred following deposition and formation of rock and oil.

What happens to reservoir pressure when a well is producing?

The well is considered to be producing with closed boundaries; therefore, there is no flow across the outer boundaries. In this manner, the reservoir pressure will decline with production and, at a constant production rate, pressure decline will be constant for all radii and times.

Which oil reservoirs are best for waterflooding?

Light to intermediate oil reservoirs having relatively low viscosity are good candidates for waterflooding. Oil having an API gravity of 20˚ or more is amenable to efficient displacement and production in a reservoir with favorable rock characteristics.
