Summary:
This paper describes the stress field and rock mechanical
aspects in the Gullfaks Field reservoirs. The data analyses are
mainly based on large volume water and gel “mini-fracs”
associated with data gathering in conjunction with propped
fracture stimulation jobs. A few data points represent results
from Pump-In/Decline Tests after perforating/before start-up
of single zone water injectors. The data are based on “state of
the art” mini-frac analysis techniques which also are discussed
in this paper.
