... fractures in Well B6-18 were vertical fractures and the azimuth of the major fracture was NE65°. During field testing, the casing in the wells to be fractured is used as the emitting current source and the surface electrodes some distance away from the emitting wells are used as the return electrodes...

... interval. Although LWD-data indicated that porous and gas-bearing reservoir had been encountered it was unclear from standard log information why reservoir thickness was reduced so dramatically. An innovative interpretation came from the use of density-image analysis. Continuous azimuthal density...

... bottom hole pressure/temperature and microseismic data throughout both stimulation and production. The first well equipped with the PDDA system was fracture stimulated in May 2000. This paper presents initial results, including interpretation of the microseismic data to determine fracture azimuth...

... the target can lead to an equally incorrect assessment of the viability of the project. Most published methods for computing wellbore position uncertainty are based on the analysis of systematic errors in inclination, azimuth and measured depth. The underpinning of such analyses is that these various error...

... Abstract Presented in this paper is a novel technique of hydraulic fracture azimuth determination. Full size oriented cores, retrieved after microfracturing, were scanned using X-ray computed tomography (CT) to evaluate the fractures. The SEM/EDAX analysis was applied to confirm the presence...
