Reservoir Engineering

Reservoir rock-fluid properties link storage (porosity, saturation) and flow capacity (permeability, mobility), forming the base for all performance prediction.

Material balance estimates hydrocarbons in place and drive behavior by equating cumulative withdrawals with expansion and support terms.

Well testing extracts kh, skin, and boundary information from pressure transient response during drawdown and buildup operations.

Drive mechanism identifies the dominant energy source pushing hydrocarbons, directly controlling pressure decline and recovery factor.

EOR methods improve sweep and displacement efficiency after primary and secondary recovery decline, targeting residual oil.
