The background  

ITC a.s has taken an initiative that hopefully will lead up to an International  Standard Practice for Leak-off tests, FIT, ELOT and Mini-frac tests. This all happened during the SPE/ ISRM, OILROCK conference in Dallas, October 2002, after a dialog between Ron Sweatman, Technology Leader - Global Business and Technical Solutions Team from Halliburton and Managing Director, ITC, Svein Fagereng.

 

Both Halliburton and ITC has through their international work, experienced a need for a common practice to do Leak-off tests in order to fully utilize this type of stress information, thus not only a focus on shoe integrity.

ITC has done a study of 5000 leak-off tests from the Norwegian Sector of the North Sea, where only 450 of these passed the quality control. 

Our conclusion is that there is need for a common practice for performing all types of LOT's, data collection and format, as well as analysis and presentation of the information.
