Hydrophysical Services

hydrolog2COLOG’S hydrophysical logging division offers clients the widest range of flow-logging capabilities of any downhole service provider. These advanced hydrophysical evaluation methods and technologies allow for an entire aquifer to be tested as one working unit yielding sensitive and accurate assessments of the vertical distribution of flow, water quality, permeability and head in any hydrogeologic environment. Services can be designed around your project’s goals, and contribute valuable and cost-effective hydrogeologic data.
