Core formulas used by reservoir engineers

Volumetrics (oil in place):

$$N = 7758 \, A \, h \, \phi \, (1 - S_w) / B_o$$

Where: N = OOIP (STB), A = area (acres), h = net pay (ft), f = porosity, S_w = water saturation, B_o = oil FVF.

Volumetrics (gas in place):

$$G = 43560 \, A \, h \, \phi \, (1 - S_w) / B_g$$

Recovery factor and reserves:

$$R = N \cdot RF \quad \text{with} \quad RF = f(\text{drive}, \text{mobility}, \text{sweep})$$

Darcy’s law (linear, single-phase):

$$q = \frac{k \, A}{\mu \, L} \, \Delta p$$

Radial flow to a well (steady-state):

$$q = \frac{2 \pi k h (p_e - p_w)}{\mu B \ln(r_e/r_w)}$$

Diffusivity (slightly compressible):

$$\frac{\partial^2 p}{\partial r^2} + \frac{1}{r}\frac{\partial p}{\partial r} = \frac{\phi \mu c_t}{k} \frac{\partial p}{\partial t}$$

Material balance (generalized oil reservoir):

$$F = N E_o + m N E_g + W_e - (W_p B_w)$$

Where: F = cumulative withdrawals in reservoir bbl, E_o/E_g = expansion terms, m = gas-cap ratio, W_e = water influx.

Arps decline (hyperbolic):

$$q(t) = \frac{q_i}{(1 + b D_i t)^{1/b}}, \quad N_p(t) = \frac{q_i - q(t)}{D_i (1 - b)}$$

Two-phase fractional flow (Buckley–Leverett):

$$f_w = \frac{1}{1 + \frac{k_{ro}/\mu_o}{k_{rw}/\mu_w}} \quad ; \quad v_f = \frac{q_t}{A \phi} \frac{df_w}{dS_w}$$

Inflow performance (oil, Vogel correlation for solution-gas drive):

$$\frac{q}{q_{max}} = 1 - 0.2\left(\frac{p_{wf}}{p_r}\right) - 0.8\left(\frac{p_{wf}}{p_r}\right)^2$$

Gas pseudo-pressure:

$$m(p) = \int_0^p \frac{2 \, p}{\mu z} \, dp$$
