... waterflood performance ( Willhite, 1986 ). Tight and very tight oil reservoirs are often associated with high clay content and significant Cation Exchange Capacity (CEC) values ( Breeuwsma et al., 1986 ). CEC directly influences smart waterflood behavior as it controls ion exchangeability between the solid...

... Abstract A successful waterflood can be implemented in a multi-layered tight oil reservoir developed with horizontal multi-fractured wells. This paper forecasts the recovery factor that can be achieved in such a reservoir as well as discusses the challenges of analyzing and modelling tight oil...

Numerical simulation was used as a tool to obtain a better understanding of the reservoir and hydraulic fracture parameters in the area along with waterflood response in the tight oil play. A history match on the pilot area was performed. Using parameters obtained from...
