An exploratory well encountered three reservoir formations S1 (perfectly cemented) S2 (poorly cemented) and S3
Q. An exploratory well encountered three reservoir formations S1 (perfectly cemented), S2 (poorly cemented) and S3 (fractured). The Formation Factor (F) is governed by the equation 𝐹 = 𝑎𝜙−𝑚, where ‘𝜙’ is the porosity and ‘m’ is the cementation factor. The constant ‘a’, linked to tortuosity is assumed to be 1 for all the formations.
