Investigation of factors affecting turn signal usage at modern roundabouts in State of Qatar
( Informa UK Limited - Taylor & Francis , 2023 , Article)Drivers are expected to use turn signals to indicate other drivers of their intentions of taking turns, lane changing, merging or diverging indicating safe driving behaviour. This study investigated the rates of turn signal ... -
Investigation of Filter Cake Evolution in Carbonate Formation Using Polymer-Based Drilling Fluid
( American Chemical Society , 2021 , Article)Drilling fluid and filtrates invasion often alter the near-wellbore flow properties during overbalanced drilling. The utilization of polymeric gels to prevent drilling fluid loss reduces the risk of formation damage caused ... -
Investigation of gas-liquid flow using electrical resistance tomography and wavelet analysis techniques for early kick detection
( American Society of Mechanical Engineers (ASME) , 2021 , Conference Paper)Gas kick is a well control problem and is defined as the sudden influx of formation gas into the wellbore. This sudden influx, if not controlled, may lead to a blowout problem. An accidental spark during a blowout can lead ... -
