... fluctuations. The production from continuous gas lift wells can be severely unstable and behave as intermittent gas lift. The trend of production loss is the norm for unstable gas lift systems. The oscillating flow affects the processing equipment and can lead to grid shutdown. Casing heading is prominent...

... Abstract During transient well testing of offshore oil and gas wells, pressure and pressure derivatives may be affected by tidal effects, resulting in periodic abnormal fluctuations that interfere with the interpretation of the model and reservoir parameters. In this paper, tidal correction...

... an intelligent intermittent lift system, facilitating the transition from manual to intelligent operations while ensuring consistent fluid level adjustments. Furthermore, the system can be optimized to align with electricity pricing fluctuations, leading to cost savings and increased operational efficiency...

... to complex pressure fluctuations. Accurate modeling and prediction of wellhead pressure during hydraulic fracturing aid engineers in real-time monitoring and risk assessment, providing a basis for adjusting pumping parameters, ensuring a smooth completion of the fracturing plan, and successful production...

... notable step changes, varying from 1.27 g/cc in well bottom to 0.05 g/cc in top part. However, it undergoes abrupt fluctuations around the x050m mark. This behavior is indicative of the fluid column movement during each pass, suggesting that it is likely not related to integrity issues but rather...

... interference and locking conditions. Since the first few months of run life, ESP1 experienced sudden fluctuation in motor current, and increase in intake pressure and motor temperature. Its production declined to outside of the minimum recommended flow range. AFPS was able to accurately identify these critical...

... the severity of torsional vibration. Modeling also suggested that applying higher torque to the bit reduces its RPM fluctuations and allows for lower surface parameters. This, in return, reduces the amplitude of the torsional vibration. Over eight trials were analyzed, and significant reductions in both...

... end of life, due to decreased gas coupled with increased water productions. Slugging is a major problem for offshore operations because it causes large fluctuations in gas and liquid production which may cause platform trips and riser vibrations. These will lead to production deferment, riser...

... Abstract Description Large fluctuations in gas and/or liquid production can lead to major disruptions on the topside facilities. These fluctuations are caused by the fluid composition, geometrical layout and operating conditions of the production system. With the current trends...

... intermittent development of 'lacustrine' conditions within the Miocene (Fig. 4). In the Malay Basin the transgressive-regressive cycles are believed to be the result of interplay of tectonic and sea level fluctuations (Mazlan, 2011), particularly during the Miocene. Evidence of tectonic deformation includes...
