Capillary Pressure by Centrifuge

Two (2) centrifuge systems for core-flooding

• One (1) ACES-300 from Core Laboratories
• One (1) CRF-840 from Ofite, Inc.

Characterize capillary pressure curves during both drainage and imbibition experiments with different fluid pairs (e.g., oil/water and gas/water)

Calculate drainage relative permeability using transient production data

Establish initial water saturation in rock core samples
