... Abstract It has been observed that pumping a mini-frac prior to a TSO Frac-pack can impact the effectiveness of the frac-pack. The calculated fluid loss parameters determined in the diagnostic test are often not valid for the main fracture design due to the residual effect of the mini-frac...

... standard decline curve analysis. The standard DCA will not accurately portray a well's production potential or its containing reservoir, which allows for severe misinterpretation. This would be detrimental to the development and optimization of the field in question. Mini-Frac tests have been used...

... Abstract The Alberta Energy Regulator (AER) requires mini-frac tests to be performed on thermal or polymer injection projects as part of the licensing process. Mini-fracture closure stress in the cap rocks is the key item used in determining the maximum operating pressure (MOP) for injection...

The main objective of the study is to calibrate well logs with available mini-frac data for estimating the minimum horizontal stress in the tight gas Monteith formation...

... Abstract Industry is currently using mini-frac analysis for the determination of fracture closure stress and after-closure reservoir properties. The foundation of all mini-frac analysis is the one dimensional Carter leak-off model, which leads directly to the concept of G Time. For 30+ years...

... Mini-fracs are performed to fracture virgin rock at in situ conditions with minimal volumes and controlled conditions but operators don't want to be at or near those conditions during normal operations. Conventional thinking says to be safe, operators need to be operating at a pressure below...

... Abstract 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...
