Formation Waters of Western Canada
Opus Handbook

The initial edition of this catalogue of formation water types was first published in 1986. The 1992 edition adds more analyses and improves the previous work. It now covers three provinces,

· Alberta - 133 Stiff diagrams based upon 2633 water analyses

· Saskatchewan - 81 Stiff diagrams based upon 1893 water analyses

· British Columbia - 50 Stiff diagrams based upon 1282 water analyses

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.

[Sample page from the Opus Handbook]

Some of the applications of this reference are:

- Resistivities - obtain accurate resisvivities 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.

- Basin/Hydrodynamic Studies - integration of water analyses with all of the geological tools creates a more complete composite picture.

- Scales & Injection Water Compatibility - Formation waters that are low in Sulphate can indicate problems with Barium Sulphate or Calcium Carbonate scales or injection water incompatibilities.

Individual sections of the Handbook can be purchased separately (order on-line) and are priced as follows in Canadian dollars:
