The primary goal of reservoir engineering is to optimize the extraction of hydrocarbons from a reservoir while ensuring efficient and sustainable production.

Igneous rocks are not typically considered reservoir rocks due to their low porosity and permeability, which hinder the storage and flow of hydrocarbons.

Reservoir pressure refers to the pressure exerted by the fluids (oil, gas, and water) within the pores of a reservoir rock.

Porosity is the measure of the void space within a reservoir rock that can be occupied by fluids, including hydrocarbons.

Permeability is the measure of the ease with which fluids can flow through a reservoir rock, influencing the rate of hydrocarbon production.

Waterflooding, gas injection, and polymer flooding are all widely used methods for improving oil recovery by displacing oil from the reservoir rock and increasing production.

Production logs provide valuable information about the flow rates, fluid composition, and reservoir characteristics, aiding in optimizing production and identifying potential problems.

Solution gas drive, water drive, and gas cap drive are all common reservoir drive mechanisms that provide the energy to move hydrocarbons towards production wells.

Pressure maintenance involves injecting fluids, such as water or gas, into a reservoir to replenish the energy and maintain reservoir pressure, enhancing hydrocarbon recovery.

Hydraulic fracturing, acidizing, and gravel packing are all widely used stimulation techniques to improve the flow of hydrocarbons from a reservoir by enhancing permeability and removing formation damage.

Well tests provide crucial information about reservoir properties, such as productivity, pressure, and connectivity, aiding in reservoir characterization and production optimization.

Reservoir simulation, material balance analysis, and decline curve analysis are all widely used methods for evaluating reservoir performance, predicting production behavior, and optimizing recovery strategies.

Reserve estimation involves evaluating geological, engineering, and economic data to determine the quantity of hydrocarbons that can be economically extracted from a reservoir.

Pressure depletion, pressure maintenance, and blowdown are all common strategies for managing reservoir pressure, influencing production rates and ultimate recovery.

Waterflooding, gas injection, and polymer flooding are all commonly used enhanced oil recovery (EOR) techniques that involve injecting fluids to improve sweep efficiency and increase hydrocarbon recovery.
