2. (11 s) Refer to Figure 1, which shows a body of rock from visual (outcrop) to thin section scales. Referring specifically to sketches A, B, and C, identify by letter the following reservoir properties, which can affect hydrocarbon storage and fluid flow: Grain size and sorting Variation in depositional energy and resulting fabric, especially sedimentary structures
