The motion of liquid filling a pipeline is impeded when the gas ahead of it cannot escape freely. Trapped gas will lead to a significant pressure build-up in front of the liquid column, which slows down the column and eventually bounces it back. This paper is an extension of previous work by the authors in the sense that the trapped gas can escape through a vent. Another addition is that the driving pressure is not kept constant but fluctuating. The obtained analytical and numerical solutions are utilized in parameter variation studies that give deeper insight in the system's behavior.

ANALYTICAL EXPRESSIONS FOR LIQUID-COLUMN VELOCITIES IN PIPELINES WITH ENTRAPPED GAS Tijsseling, Arris S.; Hou, Qingzhi; Bozkuş, Zafer (2015-01-01) High pressures and high temperatures may arise in pipelines when a liquid column is suddenly accelerated into a gas pocket trapped at a closed end. A mass oscillation occurs that is described by nonlinear equations for both liquid and gas. Analytical expressions are derived for the uniform velocity of the liquid column, from which pressures and gas temperatures follow. The obtained results are validated against theoretical and experimental results published by fellow researchers.
Analytical Solutions for Liquid Slugs and Pigs Traveling in Pipelines with Entrapped Gas TİJSSELİNG, Arris S; QİNGZHİ, Hou; Bozkuş, Zafer (2017-07-20) Liquid slugs have a relatively low mass and can therefore when they occupy a full cross-section of a pipeline be accelerated to very high velocities by means of pressurized gas. When entrapped gas pockets are present, pressures and temperatures may become dangerously high. Simple models and analytical solutions are derived and used to predict transient velocities, pressures and temperatures. The models have a generic character as they also describe the basics of breaking surface waves impacting on a wall, a...
Rapid Liquid Filling of a Pipe With Venting Entrapped Gas: Analytical and Numerical Solutions Tijsseling, Arris S.; Hou, Qingzhi; Bozkuş, Zafer (ASME International, 2019-08-01) The motion of liquid filling a pipeline is impeded when the gas ahead of it cannot escape. Entrapped gas will lead to a significant pressure build-up in front of the liquid column, which slows down the column and eventually bounces it back. The pressure and temperature in the gas may become dangerously high, and for example, lead to fires and explosions caused by auto-ignition. This paper considers the case where the trapped gas can escape through a vent. One new element is that the pressure head of the liq...
Evaluation of limestone incorporated cement compositions for cementing gas hydrate zones in deepwater environments Hıdıroğlu, İnanç Alptuğ; Parlaktuna, Mahmut; Yaman, İsmail Özgür; Department of Petroleum and Natural Gas Engineering (2017) One of the potential problems which must be overcome during oil or gas exploration in deepwater environments is to complete the drilling operations without decomposing the gas hydrates. Gas hydrates remain stable as long as the thermodynamic conditions are not changed. But, especially by increasing temperature during drilling operations, there is always a possibility of change in thermodynamic conditions, which will cause decomposition. Another factor which may disturb the thermodynamic conditions is the ev...
Assessment of production strategies of a gas condensate field using a black oil simulator: a case study Parlaktuna, Burak; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2015) Condensates are low-density liquids that are produced along with the gas phase from wet gas or gas-condensate reservoirs. Availability of these liquids makes gas-condensate reservoirs more profitable than the other gas reservoirs since condensates are gasoline like fluids with API gravities more than 45°. Although the condensate production is profitable, the management of gas-condensate reservoirs is challenging. Due to their nature, condensates condense and separate from the gas if the pressure drops below...
