Abstract Small-size at-bit azimuthal gamma geosteering tool is an important used in the process of old well sidetracking. It significant to carry out numerical simulation analysis erosion and life prediction reduce development costs excavate remaining reservoir wells. By using finite element software, we calculate analyze characteristic drilling fluid flow sand content ratio tool. These results...

The complexity of geomodelling workflows is a limiting factor for quantifying and updating uncertainty in real-time during drilling. We propose Generative Adversarial Networks (GANs) parametrization generation geomodels, combined with Ensemble Randomized Maximum Likelihood (EnRML) rapid subsurface uncertainty. This ensemble method known to be approximate non-linear forward models might therefor...

Borehole resistivity measurements are routinely inverted in real-time during geosteering operations. The inversion process can be efficiently performed with the help of advanced artificial intelligence algorithms such as deep learning. These methods require a large dataset that relates multiple earth models corresponding borehole measurements. In here, we propose to use an numerical method --re...

Compared to vertical or lowinclination wells, horizontal wells can deliver higher production rates, higher recovery factors, and more efficient use of steam in thermally enhanced recovery projects for heavy oil. However, the shallow, thin, and friable sand reservoirs in Columbia’s Girasol field present several challenges to the accurate placement of horizontal wells. Schlumberger was contracted...
