Classification of Drilled Lithology in Real-Time Using Deep Learning with Online Calibration
(Peer reviewed; Journal article, 2021)Decision making to optimize the drilling operation is based on a variety of factors, among them real-time interpretation of drilled lithology. Because logging while drilling (LWD) tools are placed some meters above the ... -
Significant surge and swab offshore Brazil induced by rig heave during drillpipe connections
(Peer reviewed; Journal article, 2021)In this paper, we describe measured and simulated downhole pressure variations (“surge and swab”) during drillpipe connections when drilling an ultradeepwater well offshore Brazil on Bacalhau (former Carcará) Field. Floating ... -
Verification of downhole choke technology in a simulator using data from a North Sea well
(Journal article; Peer reviewed, 2019)The most important contributer to Improved Oil Recovery (IOR) on mature fields is drilling of infill wells. Managed Pressure Drilling (MPD) and Continuous Circulation System (CCS) techniques can be used for improved control ...
