Paper Number: OTC-35336-MS
... by the ratio of pore pressure to bottom hole pressure. Bottom hole pressure is calculated from the mud weight and well depth and corrected for frictional losses. The pore pressure is calculated using the hydrostatic gradient. We overlaid resistivity logs from eight wells, which are sensitive to pore pressure...

... Abstract Fluid imaging technologies are used in a wide range of E&P applications. Among geophysical methods, electromagnetics (EM) determines subsurface resistivities and thus respond to fluid changes. On the path to zero CO 2 footprint, the biggest potential for EM lies in monitoring...

... and scaling in pipe and in the reservoir. Measuring formation water resistivity (R w ) goes beyond using it as the basis of petrophysical well log interpretation. It is the key to telling different waters apart for taking the most representative samples. We introduce a calibrated induction-based water...

... hydrate formation and estimation of hydrate saturation. The Work flow to estimate Petrophysical properties is guided by the high resistivity, low transit time and low density. It includes evaluation of different overlays and cross plots of wells like picket plot to firm up different parameters. Porosity...

.... The primary tool used was azimuthal deep resistivity, which uses resistivity contrast within beds to help geosteer and stay within reservoir bodies, hence optimizing well placement. Guided by azimuthal resistivity imaging, it was possible to determine the well direction relative to the beddings using oriented...

... behavior with and without NanoAl 2 O 3 up to 28 days of curing. The addition of 0.5% and 1% NanoAl 2 O 3 increased the initial sensing property (electrical resistivity) of the smart cement by 10% and 30% respectively. In a one day of curing, the maximum change in the electrical resistivity (RI 24hr...

... and are therefore difficult to differentiate. Native and invaded fluid typically do have measurably different live fluid density or resistivity. However, resistivity measurements should only be used if a temperature correction is applied. The general workflow for real-time hydrocarbon contamination quantification...
