... this objective. Wellbore Measurement For better reservoir evaluation, Well-C was logged by the through-the-bit dipole sonic (TBDS) and a formation resistivity imager in the open hole and the pulsed neutron tool in the cased hole. The TBDS provided high-quality compressional and shear slowness...

... using micro-CT images has been widely used for a number of years, there is still discussion about its accuracy and reliability. Based on previous internal studies, porosity determination via digital core analysis can be limited by the quality and resolution of micro-CT images collected and thus...

... sampling and the constant gradient slant cable towing technique to extend the bandwidth sampling. The legacy narrow azimuth 3D streamer data, acquired in the year 2001, suffers from poor imaging in the zone of interest. Though there were two successful wells with hydrocarbon discovery in the areas which...

... Abstract Positron emission tomography (PET) continues to have wide-ranging medical application and is based on the detection of gamma radiation emitted from the decay of certain types of radionuclides. Modern PET scanners produce three-dimensional (3D) images of the radiation source...

... multi-spectral ratio approach was followed to compute Q from WVSP ( Figure III ). Consistent Q value was obtained from two different approaches. Abstract Surface seismic imaging is one of the initial stages in oil and gas exploration. Low frequency content and unknown changes associated...

... Abstract Crosswell seismic provides high resolution imaging of the subsurface at the reservoir scale. The technology is used for delineating complex structure and monitoring the effectiveness of hydrocarbon recovery using time-lapse techniques. The technique employs tomographic surveying...

... Abstract Crosswell seismic is an emerging technology which provides highly detailed images of the subsurface at the reservoir scale. The technology has the potential not only to delineate complex structure but also to monitor the effectiveness of hydrocarbon recovery and CO 2 sequestration...

... Abstract Integrating conventional geologic, petrophysical and reservoir engineering rock typing methods requires studies which incorporate 3D imaging of rock material, 2D petrographic studies, fluid:fluid and fluid:solid interactions (e.g., wettability), and geological facies descriptions...

... techniques. In this paper, we illustrate how this process works using seismic data at various scales, from the low frequency reflection seismic at exploration frequency scales to those employed at well-logging scales. A rock-model-based approach especially suited for deepwater pore pressure imaging...
