Finding Value in Formation Water

Formation water analysis is a crucial step in hydrocarbon exploration and production. It provides input to petrophysical evaluation, helps assess potential for corrosion, scaling and souring, and aids in the understanding of reservoir connectivity. This article explains the causes of variation in formation water chemistry—between formations and over time. Case studies highlight methods for ensuring sample purity and demonstrate applications of downhole and laboratory evaluation techniques.

Zapping Rocks

Dielectric logging tools provide supplemental information for analyzing freshwater reservoirs and identifying movable hydrocarbons. A recently introduced tool offers a dielectric dispersion measurement to evaluate rock texture in carbonates and shale effects in siliciclastics. Case studies from freshwater, heavy-oil and carbonate reservoirs illustrate applications of dielectric data.
