... Abstract When performing classic uncertainty reduction based on dynamic data, a large number of reservoir simulations need to be evaluated at high computational cost. As an alternative, we construct Bayesian emulators that mimic the dominant behaviour of the reservoir simulator, and which...

... Abstract Different parameters of a fully convolutional network (FCN) are experimented to evaluate which combination predicts sound velocity models from a single configuration of seismic modeling. The evaluation is made considering some fixed parameters of the deep learning model, such as number...

... Abstract In recent years, as the cost of drilling, evaluating, and completing wells continues to rise in offshore, operators are seeking new technologies that offer measurements comparable to proven wireline logging technologies. Logging while drilling (LWD) technology has progressed swiftly...

... that had never been used in the area were applied, such as oil based mud (OBM), electromagnetic measurement while drilling (MWD), rigless cement evaluation, PDC bits and cased hole evaluation. These logging systems were chosen because of the high risk of losing openhole wireline tools as a result of fluid...

... This work aims to present a review of dielectric logging, including physical principles, petrophysical evaluation, and applications. In addition, we will present a history of its use in Petrobras oilfields. The dielectric properties are generated by the charge alignment created...
