... and in some cases, we may have incomplete sonic log data due to tool damage, poor calibration, and other reasons. In other cases, the well of interest might only have a triple combo suite to determine target depths and left up to engineering judgment what a hydraulic fracture might look like. This study...

... examined in the study. The research was carried out for the log data from Williston Basin, USA and the Norwegian Lille-Frigg oil field on the North Sea. Sonic log (DT), neutron porosity log (NPHI), deep resistivity log (LLD) as well as density log (RHOB) were utilised in the study. A python program has...

... Abstract Alternating conventional and unconventional reservoir layers in the Permian Basin challenge the acquisition, processing, and interpretation of water saturation (Sw) using nuclear magnetic resonance (NMR) log data. A new-generation NMR wireline tool addresses these challenges using...

..., if not impossible, to derive Archie's ‘n’ parameter without additional information. Research combining core and log data shows evidence of a positive correlation between Archie's saturation exponent and the total organic content (TOC) in a given unit volume. Using this relationship, Archie's equation may be used...

... for the dynamic model. The static model is developed through an integration [AG2]process. It consists of both matrix and fractures. The matrix modeling started by integrating 3D seismic and log data to build the structural model. A new rock type scheme was developed by reconciling log and core data, including...

... Abstract Schlumberger and four Eagle Ford Shale Play operators drilling in South Texas joined a consortium initiative to acquire various types of open hole logging data in several horizontal wells, and use the data to design the completions with optimum fracture stage and perforation cluster...

... interpretation is somewhat limited. This study was undertaken to determine: (1) if facies could be successfully predicted (classified) from well log data and (2) if the predicted facies could be used to extend the stratigraphic and depositional interpretation to the flanks of the reservoir. Efforts to predict...

... Abstract Seismic inversion is the essential first step to ensure proper integration of seismic data, well log data, and geological and petrophysical information. In this article, we compare principles, key methods, work flow, advantages and disadvantages, and application conditions for several...

... and D for multiple acquisition modes. The second method is to invert simulated NMR echo data. Lastly, we compare real NMR log data porosities with other porosity logs in fields exhibiting long T 1 constants. In all three cases, we show how porosity is under-or over-estimated beyond the expected...

More aggressive water control techniques were employed in one well, where a fault intersection caused a major water influx in the middle of the perforated section. The water productive intervals were squeezed and the surrounding oil...
