In-Situ Stress Measurements During Drilling

Journal of Petroleum Technology, 1986
Summary This paper describes the results of six microfracturing experiments in a gas well in south Texas. The experiments were conducted in open hole and during the drilling operations. Microfracturing consisted of pumping very small volumes of drilling mud (tens of gallons) at very low rates (3 to 30 gal/min [189 ...

Analysis ofin-situ stress measurements

Geotechnical and Geological Engineering, 1997
In order to analysein-situ stress measurements two approaches are discussed. These are eigen-value analysis and statistical techniques such as Arnold, Fisher and Bingham distributions. When these techniques are applied to field data, the results are quite consistent.

A Comprehensive Approach to in Situ Stress Measurement

Advances in X-ray Analysis, 1985
Recent developments in position sensitive detectors (PSD's), solid state power and computer technologies make it possible to design accurate instruments for in-situ stress measurement. Such instruments require compromises in the interests of portability, size and speed stiich may limit accuracy and/or versatility.
