Abstract: A method for determining volumetric data for fluid within a geological formation is provided. The method includes collecting first and second dataset snapshots of the geological formation based upon measurements from the borehole at respective different first and second times and generating a differential dataset based upon the first and second dataset snapshots. Multiple points are determined within the differential dataset, including a first point representing a first displaced fluid, a second point representing a second displaced fluid, and an injected fluid point that corresponds to properties of the injected fluid. A further third point is determined based on at least one other property of the displaced fluid, and a volumetric composition of the displaced fluids is determined based upon the differential dataset, the first point, and second point, and third point.

Abstract: Software-based quality control analysis of well log data. At least some of the various embodiments are computer-readable mediums storing a program that, when executed by a processor, causes the processor to read data from a well log, and perform a quality control analysis on the data.

Abstract: A method for determining compositional data for fluids within a geological formation having a borehole therein may include collecting first and second dataset snapshots of the geological formation based upon measurements from the borehole at respective different first and second times, and with the borehole subject to fluid injection between the first and second times to displace fluids in the geological formation adjacent the borehole. The method may further include generating a differential dataset based upon the first and second dataset snapshots, normalizing the differential dataset to generate a normalized differential dataset, determining vertices defining a geometric shape and corresponding to respective different displaced fluid signatures based upon the normalized differential dataset, and determining displaced compositional data with respect to the different displaced fluid signatures based upon a position of a datapoint from the normalized differential dataset on the geometric shape.
