Research paper thumbnail of An Extensive Study on Desorption Models Generated Based on Langmuir and Knudsen Diffusion

Energies

Although gas desorption is a known phenomenon, modeling fluid flow in tight gas reservoirs often ... more Although gas desorption is a known phenomenon, modeling fluid flow in tight gas reservoirs often ignores the governing desorption effect, assuming that viscous transport is the predominant controller, resulting in an erroneous prediction of mass transport and fluid flow calculations. Thus, developing a new model accommodating all the major contributing forces in such a medium is essential. This work introduces a new comprehensive flow model suitable for tight unconventional reservoirs, including viscous, inertia, diffusion, and sorption forces, to account for fluid transport. Based on Langmuir law and Knudsen diffusion effect, three models were generated and compared with different known models using synthetic data. The model was solved and analyzed for different scenario cases, and parametric studies were conducted to evaluate the desorption effect on different reservoir types using MATLAB. Results show that the contribution of the sorption mechanism to the flow increases with the ...

The new modification addresses the fluid transport phenomena into three scales incorporating a diffusion term. In this study, a new liner model, numerically solved, has been developed and deployed for a gas huff and puff project. The new model has been numerically validated and verified using synthetic data and huff and puff case study. Ideally, the new model suits fluid flow in tight UCRs. The modified Forchheimer’s model presented is solved using the MATLAB numerical method for linear multiphase flow. For the huff & puff case, very simple profiles and flow dynamics of the main flow parameters have been established and a thorough parametric analysis and verifications were performed. It has been observed that the diffusion system becomes more prominent in regulating flow velocity with low permeability of the formation rock and low viscosity of the flowing fluid. Th...

The strategy is based on a hierarchical approach that introduces process concepts to assure simplicity, flexibility, and scalability as well as integration with external platforms without compromising on accuracy. As a part of ADNOC Onshore's implementation of the IAOM, well and network models were constructed and calibrated for modelling field scenarios, identifying bottlenecks, and replicating business requirements. The new approach is rooted in concepts to assure maintainability of the network model. A hierarchical approach implemented during construction and calibration was defined in levels from wells to processing facilities, and was later standardized for ease of replication of structures. Without compromising on accuracy, the new approach delivered ease of construction, calibration, and analysis that was not possible in an earlier field model. The f...

Research paper thumbnail of Well Performance Improvement By Identifying And Preventing Liquid Loading Using An Integrated Asset Operation Model Framework For Gas Condensate Wells

Day 1 Mon, November 09, 2020

Analyzing this bottleneck using physics-based model estimations is one of the key methodologies in an integrated digital production system, which can help users to take preventive actions, thereby saving cost, time, and efforts considerably. This paper demonstrates the identification of the liquid loading condition in existing producing gas condensate wells using the analytical tools and automated workflows in an integrated framework. The analytical workflow to investigate liquid loading bottlenecking requires calibrated and representative well models as a first step. These representative well models incorporate a tuned compositional PVT model as a fluid parameter model, and such model outputs match with wells deliverability and historical production trends. Subsequently, the calibrated models are then integrated into a digital platform consisting of automated well analysis wo...
