Determination of the Orientation of Open Fractures from Hydrophone Vsp

Open fractures are of interest in many areas such as ground water contamination, hazardous waste disposal, oil and gas recovery, and geothermal energy extraction. In borehole geophysics and engineering, fractures are usually located by acoustic borehole televiewer logging, however, not all of the observed fractures are permeable. The caliper log, on the other hand, provides the information abou...

Experimental Verification of Acoustic Waveform and VSP Seismic Tube Wave Measurements of Fracture Permeability

A variety of established and experimental geophysical techniques was used to measure the vertical distribution of fracture permeability in a 229-meter deep borehole penetrating schist and quartz monzonite near Mirror Lake, New Hampshire. The distribution of fractures in the borehole was determined by acoustic borehole televiewer and other geophysical logs. Fracture permeability was estimated by...

Down the borehole but outside the box: innovative approaches to wireline log data interpretation

Many innovative approaches to using data to make inferences about aspects of the natural world necessitate the calculation and appraisal of large numbers of alternative models or the repeated sampling of a multi-parameter solution space. While this is not new to science, it has hitherto been restricted to either very simple models, or to institutions with powerful computing infrastructure. Such...

Primer on Statistical Interpretation or Methods

ion of Analytic Methods in PropensityScore–Matched Samples The following information was abstracted from each of the published articles: (1) the method by which propensity-score– matched pairs were formed; (2) whether the authors assessed the balance in measured baseline characteristics between treated and untreated subjects in the matched sample, and when the authors did so, whether appropriat...

Fracture Reservoir Characterization by Fiber-optic Distributed Temperature Log

One of the important features of the fiber-optic distributed temperature log is its ability to acquire continuous, instantaneous and simultaneous temperature profile along the entire wellbore. Series of successive temperature profiles sampled every one minute or so enable to analyze transient temperature phenomena, which may pertain to important reservoir properties. For example, when change of...
