Abstract
A method of ascertaining or measuring subterranean events includes use of deuterium oxide-depleted water as a tracer. The presence of deuterium oxide-depleted water may be measured at a subterranean location by means such as core sampling, for any purpose for which tracers are known to be useful. For example, the presence or absence, and level, of deuterium oxide-depleted water in a core sample may be used to determine fluids saturation levels, porosity and permeability, as well as other subterranean formation and/or reservoir characteristics important to the oil and gas production industry.
