... on acoustic logging and its potential applications. Our results, in addition to developing an effective method for eccentric tool wireline logging (WL) and acoustic logging while drilling (ALWD) modelling, can be used to provide a theoretical basis for tool development and data interpretation. Furthermore...

... Wellbore instability is a major safety and environmental concern in drilling. A machine learning method is proposed to train a field-scale digital geostructure and geomechanics model to evaluate wellbore stability for well planning and drilling. The digital workflow involves characterizing...

... Geothermal energy heavily relies on the drilling of wells into challenging formations characterized by high temperatures. To optimize the drilling process, it is crucial to enhance the rate of penetration (ROP). However, accurately capturing long-term patterns in ROP, including accuracy...

... or animations could be exported and shared. The MSEEL dashboard allows sharing of a fully interactive model. Logging while drilling wellbore image logs to detect pre-existing fractures integrated with microseismic, distributed acoustic sensing (DAS) and distributed strain sensing (DSS) during completion show...

... In a well drilled in the DOE FORGE Geothermal test site both electrical borehole scans acquired using Schlumberger’s Formation Micro-scanner Image tool (FMI) and Stoneley waves generated by a borehole sonic tool are used together in a workflow using the strengths of both techniques...

... We talk incessantly about the value of discipline integration and the need for technical collaboration, but disconnects remain common in our project work. Engineers are busy drilling, completing, producing and forecasting wells, while Geoscientists are expected to provide a volumetric check...

... The northern part of Argentina offshore is one of the most underexplored areas in the world. The latest petroleum exploration in Northern Argentina offshore was in 1990s, with a few well drillings only targeting the highs along the basins. Newly acquired 2D seismic data indicates the thickness...

... In the process to add more reserves, exploration wells are being drilled targeting unconventional tight gas at depth intervals of 4500m-5300m TVD. With limited dataset available in structure, high quality borehole images and far field acoustic measurements at high temperature are key to build...

..., this method is applied to the landing of horizontal well W5H of Bohai A Oilfield and the error of predicted depth and actual drilling depth is 2m, which ensured successful landing of horizontal wells. Note: This paper was accepted into the Technical Program but was not presented at IMAGE 2022 in Houston...

... Here we analyze ambient noise (AN) data generated during drilling of exploration boreholes and recorded using dense array deployed over one of the numerous shallow iron-ore mineralization targets in the Pilbara region (Western Australia). We propose an automatic workflow to evaluate complex...

... ABSTRACT We present the results of a pilot test where we passively monitored the drilling of an appraisal well in the Wisting discovery in the Barents Sea with an ocean-bottom cable deployed temporarily around the drilling rig. The continuous passive recording of drilling vibration signals...

... porosimetry, and borehole nuclear magnetic resonance (NMR) to estimate unsaturated water storage below the soil. Our drilling and road cut characterization revealed a fractured bedrock vadose zone to at least 4 m depth underlying the conifer forest, composed predominantly of Engelmann spruce and subalpine fir...

... involving an anisotropic shale layer as well as an isotropic sandstone reservoir layer. The results of the numerical experiments suggest that the new method can be used to gradually reconstruct a complex geological structure while drilling, leading to a improved geosteering and increased oil recovery...

... ABSTRACT Well completion process is a fundamental stage in a study of well, since allows transforming a drilled well into a producing well. An efficient well completion design can make the difference between a high and a low production. In an unconventional well of high angle in an oil field...
