To recover reserves from a low pressure reservoir requires very low flowing bottomhole pressure. Wells, in Gas Well Deliquification (Second Edition), 2008 Late-life Deliquification The results were a 10% incremental production increase through a downtime reduction for the wells and debottlenecking gathering networks, a more stable operating envelope for 55 wells with liquid loading issues to avoid deferred production, and extra capacity of 22,000 m³/d through improved artificial lift methods simulation.James F.
GAS LIFT PIPESIM CORRELATIONS SIMULATOR
With the PIPESIM simulator the UkrGasVydobuvannya engineering team was able to simulate several fields that shared the same infrastructure. Increased gas production and avoided deferred production The network performance was also analyzed and fine-tuned for winter and summer production demands.įurthermore, the PIPESIM simulator enabled the UGV engineers to generate field simulations with 1,800+ wells in minutes instead of days thanks to a single interface for both wells and pipeline networks simulation, superior modeling capabilities with its parallel solver, automated correlation matching, and ability to visualize the results both in the conventional way and on the GIS network view, enabling easy identification of current and future bottlenecks. The company identified maximum production potential for each well and was able to understand the spare capacity to meet the increased demand for gas in winter while improving well performance and the lifespan of the reservoir. This enabled the company’s engineers to reduce unplanned downtime due to liquid loading by choosing the right production regimes. The PIPESIM simulator was used to verify production regimes or operating envelopes for wells with liquid loading issues.
The result was a model that proved its quality with an accuracy of more than 95% for pressure and rates. The matching process was carried out first by trunklines individually, then all together. Pressure was set up at the boundary conditions in the central process facilities and the network model was matched against production rates and pressure at source point and intermediate points along the network.

The model created had a detailed description of each well including a full wellbore diagram, inclusive of perforation intervals, deviation profiles, heat transfer coefficients, inflow performance data, detailed geometry profile and pipeline characteristics, compositional data for the fluid, and soil conductivities and temperatures.
During creation of a pipeline network, a significant amount of time was spent automatically exporting digitized topology data into the PIPESIM simulator from the UGV's GIS data. Schlumberger helped UGV identify the right dataset, perform QA and QC of the field data, build a network model using the PIPESIM simulator based on 10 wells, and then gradually scale up to 69 wells for three interconnected fields.
GAS LIFT PIPESIM CORRELATIONS MANUAL
Manual and analytical workflows were replaced with computer-based numerical simulation using the PIPESIM simulator to provide an effective decisions-support platform for the UGV engineering team. Use a multiphase flow simulator to improve performance fieldwide
GAS LIFT PIPESIM CORRELATIONS SOFTWARE
To overcome these challenges and reach its production targets, UGV selected Schlumberger to provide a simulation software solution. The legacy analytical tools used by the UGV engineering team were not able to account for the full physics of the multiphase flow from the wells, making it challenging for them to efficiently identify wells with liquid loading problems, select the best intervention method to bring wells back online, create optimal artificial lift designs, manage hydrate formation, and identify infrastructure bottlenecks.
