... turbiditic sequences is often problematic due to the highly anisotropic setting, which affects the formation evaluation from conventional LWD, wireline logs and mudlog data. The reservoir, fluid content and pay petrophysical parameters are usually underestimated. Time and cost constraints can prohibit...

... based on good quality data set from eight wells. After that, the geomechanical model was validated using the caliper data and drilling experience. A key part of the model building was the estimation of pore pressure using wireline logs, gas inflows during the drilling, production data and minifrac tests...

...Introduction Abstract Information from cores and wireline logs, processed according to different methodologies, were integrated to provide a consistent facies classification, petrophysical characterization and 3D geological model of a deep-water turbidite reservoir in the Gulf of Mexico...

... Measurements made with wireline logs are often used as the reference for well depth. However, differences are usually noted between wireline depth ("Logger's Depth") and depth based on the drill pipe tally ("Driller's Depth") or the casing tally, frequently leading to the obvious question: "which one...

... pressure curves is much longer than that suggested by the wireline log evaluation. In these situations, and if there are residual hydrocarbons evident below the pressure-derived Free Water Level (FWL), the hydrocarbon saturations are better modelled using imbibition capillary pressure curves...

... A model for estimating effective permeability to gas was developed with the integration of wireline log, net overburden stressed (NOB) Klinkenberg corrected core data, and well test effective permeability data. 5 , 7 The permeability model uses porosity and a Modified Simandoux water saturation...

... Abstract Wireline logs and logging-while-drilling (LWD) logs are important pieces of the formation evaluation puzzle. They are often the basis for the initial economic evaluation of a prospect and serve as references for monitoring reservoir depletion. As the data from the LWD devices...
