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