... displacement of oil by water in a water-wet porous matrix block owing to imbibition of water into the block from the surrounding fractures is carried out by adopting Civan's 25 formulation and by implementing a number of simplifying assumptions similar to Reis and Cil 6 . An immiscible two-phase fluid...

...INTRODUCTION Estimation of the extent of mud filtrate invasion and distribution within the near wellbore formation during drilling operations is essential for accurate well-log interpretation (Civan and Engler 1 ). This process is complicated by the formation of a mud filter cake and its...

... ) are the discrete function values of these points, are the weights associated with these function values. In general, x can be expressed in any coordinate system and it can include the time variable, leading to a time-space formulation as demonstrated by Civan 1 , 24 . For example, for a transient state process...
