This paper presents the results of a restimulation workover program in the Norge Marchand Unit performed during the past seven years. Upon initial completion these wells were fractured with Ottawa sand. It was suspected that a loss in fracture conductivity had occurred as a result of the proppant crushing due to the high closure pressure (7000 psi). In an effort to improve the fracture conductivity, the wells were refractured using intermediate strength proppant. The use of pressure buildup tests to select restimulation candidates improved the likelihood of having a successful treatment. The successful refractures resulted in an average increase of 50 B0PD and 98 MB0 additional reserves per well.
