Analyzing Single- and Two-parameter Models for Describing Oil Recovery in Imbibition from Fractured Reservoirs

Mojtaba Ghaedi; Sadegh Ahmadpour

Volume 9, Issue 3 , July 2020, , Pages 11-25

  The imbibition process is known as one of the main production mechanisms in fractured reservoirs where oil/gas-filled matrix blocks are surrounded by water-filled fractures. Different forces such as gravity and capillary play a role in production from a fractured reservoir during imbibition and complicate ...  Read More

An Efficient Method for Determining Capillary Pressure and Relative Permeability Curves from Spontaneous Imbibition Data

Mojtaba Ghaedi; Zoltán E. Heinemann; Mohsen Masihi; Mohammad Hossein Ghazanfari

Volume 4, Issue 3 , July 2015, , Pages 1-17

  In this paper, a very efficient method, called single matrix block analyzer (SMBA), has been developed to determine relative permeability and capillary pressure curves from spontaneous imbibition (SI) data. SMBA mimics realistically the SI tests by appropriate boundary conditions modeling. In the proposed ...  Read More
