... to deliver high quality, cutter-by-cutter dull grades connected with the drilling meta data from a drilling records database. The model is trained on more than 20,000 images which classify cutter primary characteristics into worn cutter, chipped cutter, broken cutter, spalled cutter, delaminated, bond...

... to properly investigate the stabilizer's design characteristics. Therefore, a time-domain dynamics approach is adopted in this work. A detailed modeling of bladed stabilizers including the blade geometry (number of blades, spirality, and blade width) and friction characteristics are introduced in an existing...

... the last years to tackle those issues. One of the objectives is to enable seamless integration of drilling automation system, and a key component is the so-called "semantic interoperability" layer. This layer provides the means to represent the various characteristics of real-time drilling signals in a way...

... Abstract The paper addresses the gas loading characteristics of the drilling fluid and its influence of the gas influx rate during the flow check operation. In particular, the resulting fluid expansion in the wellbore annulus and the capability to detect gas kick at HPHT process conditions...

..., rapid learning was a by-product of personnel rotation and the need to train successors. Recent research suggests that high reliability organisations have five important characteristics: a preoccupation with failure, a reluctance to simplify, sensitivity to operations, resilience and a respect...

.... Although techniques are now available that enable successful drilling of many of these large salt structures, there still are some formations with characteristics that make drilling challenging. This paper focuses on one such ultradeep subsalt prospect and the strategies used to overcome the key issues...
