Quantification of fluid losses at the topside is beneficial for early kick‐loss detection and
automation of the drilling operation. A model‐based estimator is a useful tool for this …

Early kick and loss detection is a major concern in any drilling operation. A real-time return
flow rate measurement would be an added advantage for the early kick and loss detection …

This paper studies reduced-order-models for the fluid flow problem of a digital valve, and
whether it may efficiently be formulated by a deep Artificial Neural Network (ANN) to model …

Early kick/loss detection is a crucial part of safe well control, and it plays a major role in the
reduction of risk and non-productive time in drilling. In conventional drilling, topside sensing …

During drilling operations, it is of vital importance to have accurate and reliable volume
control, with as fast as possible detection of flow abnormalities. The earlier a flow …

Real-time estimation of the return drilling fluid during oil well drilling is investigated in this
study. Online fluid level measurements from a Venturi channel which can be placed on the …

Pressure control during well drilling operations includes management of the well pressure
above the formation pore pressure and below the formation fracture pressure. If these …

A real-time flow measuring algorithm is developed for the open Venturi channel non-
Newtonian flow measurement. Using a single level sensor reading at downstream of the …

Early kick/loss detection is a crucial part of safe well control, and it plays a major role in the
