... ACOUSTIC MULTIPOLE MEASURMENT Since the borehole acoustic measurement configuration is of cylindrical geometry, it is useful to think of cylindrical rather than plane waves. That is, instead of considering the borehole fluid pressure to be an infinite superposition of plane wave contributions...

... integrated across two distinct energy windows to represent the relative contribution of carbon and oxygen corresponding to saturation of oil and water. With high spectral resolution gamma ray detectors, an improved method was developed that deconvolves inelastic gamma ray spectrum into constituent components...

... production and improved understanding of the role vugular zones and matrix permeability contribute to fluid mobility is key to future development. The significance of this work is that it presents a multidisciplinary approach, combining openhole and casedhole petrophysics, to optimize producibility...

... of mineralogy is a critical step in formation evaluation. It enables porosity and saturation computations and provides input to definition of lithofacies and lithostratigraphic units. It also contributes to completion and stimulation designs. In the context of carbon capture and sequestration (CCS) projects...

.... It is observed that the iso-sensitivity envelope encompassing 50% of cumulative contribution from the tools is within the distance of about one source-receiver coil-separation, L, or less. This is consistent with the depth of investigation for wireline induction logging tools defined through the integrated...
