摘要： A method and system for performing speed correction on nuclear magnetic resonance logging data is provided. The speed correction performed can be done on a representation of echo data received by a logging tool, and then additively applied to the echo data. Such a process can reduce or remove the amplification of noise in the echo data that is common in conventional methods of speed correction.

摘要： Various methods are disclosed for evaluating water saturation characteristics in a geological formation penetrated by a borehole, including injection fluid introduced into the formation by an external injection process performed upon the formation. In various embodiments, the total water saturation may be obtained from the relationship provided by the Triple Water Equation, and used to map saturation in the formation and making drilling decisions.

摘要： In one aspect of the present invention, a method of evaluating water saturation characteristics is provided. The method is applicable to a geological formation that is penetrated by a borehole and includes injection fluid introduced into the formation by an external process performed upon the borehole. The method includes conducting electromagnetic induction measurements indicative of resistivity values of the formation. A value of total porosity for the formation is also obtained. Then, the method calls for defining fractional volumes for each of clay bound water, free water, and irreducible water in the formation, wherein the free water volume accounts for injection fluid introduced into the formation. The method also calls for defining values of conductivity for each of clay bound water, free water, and irreducible water, wherein the free water conductivity is determined from the conductivity of the injection fluid. Finally, water saturation in the formation is determined from a relationship between total porosity and conductivity values for the formation, and conductivities and fractional volumes for each of clay bound water, free water, and irreducible water. This relationship is preferably provided by the Triple Water Equation.
