Fewer than 20% of water analyses in the EUB files or privately digitized databases are pure formation waters. The bulk of the data is composed of mixes and mud filtrates. This catalogue supports your application of these databases by providing a reference of the pure waters in your particular study area.
​
The initial edition of this catalogue of formation water types was first published in 1986. The 1992 edition added further analyses to cover three provinces.


133 Stiff diagrams based upon 2,633 water analyses

50 Stiff diagrams based upon 1,282 water analyses
SOME OF THE APPLICATIONS OF THE OPUS HANDBOOK ARE:
​​
RESISTIVITY:
-
Obtain accurate resistivities for your area
​​
DST INTERPRETATION:
-
Pure filtrate recovery can indicate by-passed pay.
​
SEPARATION OF POOLS:
-
Vertical and lateral separation is shown by different water patterns.
​
COMPLETION PROBLEMS:
-
Recognition of the source of water inflow can help in cases of poor cement bonding or casing leaks.
​
RECHARGE AREAS:
-
Formation waters that are high in bicarbonate indicate surface recharge of the aquifer.
​
HYDRODYNAMIC STUDIES:
-
Integration of water analyses with all of the geological tools creates a more complete composite picture.
