Abstract This paper presents a method to eliminate production loss due liquid-loading in tight gas wells. Cyclic shut-in control is simple strategy that particularly benefits lower-permeability stimulated wells, including but not limited shale Comparison made between well producing (1) "ideal" situation where 100% of liquids entering from the reservoir or condensing tubing are continuously removed (without shut-ins), (2) meta-stable condition with low rate, typical most wells today, and (3)...

CRAFT (Computerized Relative Allocation of Facilities Technique) has been developed improve an existing layout, while ALDEP (Automated Layout Design Program) is a construction The improvement given by over technique was found reduce annual material handling cost 23% [1]. This study hypothesize that better result could be gained combined two rather than their independent...

Monitoring natural gas transmission in a pipeline network is important to maintain the supply and demand balance transactions distribution. Gas pressure, temperature, flowrate, properties must be monitored during process. These variables, also known as operational conditions, need simulated carefully understand dynamics behavior over time. Commonly used physical equations, such thermodynamic or hydraulic have limitations simulating future trends because they some boundary conditions solved....

Abstract Carbon Dioxide (CO2) injection is a common process used to increase hydrocarbon production in oil and gas fields, which known as the enhanced recovery (EOR) process. This paper presents modeling of carbon capture, utilization storage (CCUS) project using an integrated operation optimization approach. In this case study, subsurface system consists two different reservoirs, condensate reservoir. The products from reservoirs are processed single surface processing facility. CO2 will be...

Abstract This paper presents a study about corrosion-erosion phenomenon in natural gas production pipeline when FeS scale is formed on the inner surface of pipeline. chosen here because its reaction faster and more reactive than other such as FeCO3. A literature was firstly conducted to develop idea model. Several phenomena were considered be best describe process. Then, mathematical model calculate rate derived. The process divided into two steps: fluid flow heat transfer establish...

Corrosion is a critical issue during the development of gas field, especially wet or retrograde field. affects management system field and further impacts amount investment. Therefore, accurate prediction corrosion rate needed to plan an effective preventive action before going phase. One important parameters that should be noticed create formation passive layer. In CO2-H2S environment, there will three possibilities layer: FeS, FeCO3 no this study, we mathematical models determine formed...

The existence of passive layer is important to control the corrosion-erosion rate in gas production pipes. However, can lead two possible conditions: protection or scale build-up. Accurate prediction scaling tendency needed plan treatment and operating condition during from field. In this study, we develop mathematical model predict consists basic equations: precipitation erosion equation. Precipitation calculated using semi-empirical correlation Salama (2000) Then, a modified parameter...

Abstract One of the major concerns in a multi-layer system is that interlayer cross-flow may occur if reservoir fluids are produced from commingled layers have unequal initial pressures. Reservoir would commonly bigger average pressure (pore fluid pressure) as it goes deeper. The phenomenon is, however, not followed by productivity or injectivity. existence with quite low average-pressure and high injectivity tend experiencing problem. It bottom layer flowing into upper layer. strict...

Proper monitoring of natural gas transmission in a pipeline network is necessary to ensure balance supply and demand. Physical correlations such as hydraulic thermodynamic equations, although has been applied widely many use cases simulate flow throughout pipelines, have their own limitation forecasting future trends. For that matter, data-driven technique needed. In this paper, deep neural with multi-layer Long Short-Term Memory (LSTM) cells implemented forecast values operational...
