... Abstract Accurate prediction of pressure gradient in gas wells is the theoretical basis of gas well performance analysis, production optimization and deliquification technologies design. Experiment is the best access to characterize the flow behavior of gas wells. For low-pressure experimental...

... prediction. Wrong prediction and control around it can impair the performance of the well. Turner (1969 ) assumed a range of Reynolds number (10 4 < N Re < 2 * 10 5 ) but gas rates in gas wells are majorly above the suggested range. Arising from that, an adjustment was made to the Turner equation...

The subject of this work is a gas well with an extended horizontal wellbore, in which the 18-stage hydraulic...

.... During 2019, more than 30 wells were mechanically cleaned using slick line to remove scale every 30 days approximately. This paper describes the study of the origin of scale in gas wells producing from multiple formations and the chemical technology applied to solve this problem in the mature urban field...

... identified the key concepts that were applicable to the well in our study. We applied the existing equations for the critical gas rate required to lift liquids in gas wells and highlighted the variation in gas velocity with changing pressure and temperature along the vertical part of the wellbore. Using...

..., thousands of multilateral gas wells have been drilled in the last decades. A multilateral well is defined, in general as a well with multiple branches in the lower borehole targeting oil and gas reserves in the same or different strata. These branches are called laterals. Multilateral wells...

... Abstract This paper investigates the impact of high-rate production on well performance of a cased-hole gas well with a fracpack type of completion. We modeled fluid dynamics in the near wellbore region, where the most drastic changes in pressure, velocity and temperature are expected to occur...

... For R ≥ 0.007 (11) r = 28.5 τ ρ m V m 2 Abstract Proper design of gas wells requires accurate estimation of pressure profile. This task is usually carried out by integrating mechanistic models and correlations along the well trajectory. Gray (1975) correlation...

... Abstract Liquid loading, a common problem in matured gas fields, is investigated experimentally in highly deviated gas wells. The experiments were carried out using air and water in a 3-in ID pipe at well deviation from 60° to 88° from vertical. Pressure gradient and liquid holdup were measured...

... Subsea high-rate gas wells (i.e., those with a production tubing OD ≥ 7–5/8”) are becoming more common in the global well inventory, with their usage now spanning four continents. Still, the absolute count of such wells (< 50) is not large relative to the overall number of subsea wells...

...Well Results Campaign Approach As is clear from the problem statement above a group of 6 gas wells has been unable to flow because of solids production problems. It was expected that all wells would benefit from solids control, evidenced from the fact that none of the wells that were...
