Available in PDF, EPUB and Kindle. Book excerpt: Numerical simulation is an essential tool in the design and development of oil recovery strategies, and is particularly important for the more costly and marginally economic recovery schemes contemplated for heavy oil and bitumen recovery. One process that has shown excellent promise is the horizontal-well gravity-drainage stream injection process. In field trials, it was found that the formation is heated only in a spherical zone around the injection well. To resolve these problems, this report develops a two-dimensional simulator to track the location of the steam front explicitly within a finite-difference procedure, so that the phenomena at the stream front can be more accurately simulated. The report presents details of the mathematical analysis required to incorporate the time-dependent coordinate transformation and the finite-difference representation.

This book was released on 1993 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report details the findings of an in-depth study undertaken to assess the viability of the steam injection process in the heavy oil bearing Nacatoch sands of Arkansas. Published screening criteria and DOE's steamflood predictive models were utilized to screen and select reservoirs for further scrutiny. Although, several prospects satisfied the steam injection screening criteria, only a single candidate was selected for detailed simulation studies. The selection was based on the availability of needed data for simulation and the uniqueness of the reservoir. The reservoir investigated is a shallow, thin, low-permeability reservoir with low initial oil saturation and has an underlying water sand. The study showed that the reservoir will respond favorably to steamdrive, but not to cyclic steaming. Steam stimulation, however, is necessary to improve steam injectivity during subsequent steamdrive. Further, in such marginal heavy oil reservoirs (i.e., reservoir characterized by thin pay zone and low initial oil saturation) conventional steamdrive (i.e., steam injection using vertical wells) is unlikely to be economical, and nonconventional methods must be utilized. It was found that the use of horizontal injectors and horizontal producers significantly improved the recovery and oil-steam ratio and improved the economics. It is recommended that the applicability of horizontal steam injection technology in this reservoir be further investigated.

This book was released on 2018 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal enhanced oil recovery techniques have been considered as the best approach to produce heavy oil; however, hybrid methods, which are combinations of different oil recovery methods, reveal more promise in enhancing oil production from heavy and viscose reservoirs. In this research, we investigate improving recovery from heavy oil reservoirs, considering steam foam method to control the mobility of steam and oil in such reservoirs, and delivering proper amount of heat to reservoir in order to reduce oil viscosity. In this thesis, a compositional K-value based reservoir simulator, CMG-STARS, was used to build simulation models for all case studies. Steam table is used to calculate the phase change during steam injection and to capture latent heat effect on energy balance and mass balance equations. CMG-STARS empirical foam model is used to capture mobility of steam in the presence of surfactant. Simulation models are tuned with experimental core data and field history data. Simulation results illustrated that a considerable increase in oil recovery is obtained when steam foam is used. It is also observed that foam parameters, which was used in modeling, affects oil recovery, reservoir average temperature, average pressure and gas saturation. Optimized foam parameters were determined considering oil recovery, average reservoir temperature, and average reservoir pressure. Finally, simulations revealed that field and simulation results were in good agreement with field data, and that steam foam oil recovery method has the potential to become a promising oil recovery method for heavy oil reservoirs.

This book was released on 2021 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steam-assisted gravity drainage (SAGD) is a commercially successful technology for heavy oil and bitumen recovery. The energy efficiency of SAGD is important for the economic feasibility and environmental sustainability of oil recovery. Solvent-assisted SAGD (SA-SAGD) has been widely studied and pilot-tested as an alternative to improve the energy efficiency of SAGD. One of the practical factors that affect oil producers is the produced oil properties. Multiphase behavior and reservoir flow collectively affect produced oil properties. However, the compositional effect on properties of the produced oil in SAGD and SA-SAGD remains unknown. This research focuses on answering the question of how the oil properties are affected by steam injection and solvent-steam coinjection, by studying the interaction of multicomponent phase behavior and reservoir flow. The research question was answered by an experimental and numerical investigation into SA-SAGD using condensate, a multicomponent solvent to be used for a field pilot in Alberta. It contains components with a broad range of carbon numbers and complicates the compositional flow in SA-SAGD. Steam injection experiments were conducted for SAGD and SA-SAGD in a large lab-scale physical model, and the compositional effect was analyzed through both compositional analysis for the produced oil and history matching with numerical simulation. Then, the compositional flow was further investigated in field-scale 3-D numerical simulations with heterogeneity representative of Athabasca oil sands, Alberta, Canada. Experimental results confirmed for the first time that SAGD produced lighter oil than the original bitumen because of the distillation of light-end bitumen components. Experimental and simulation results showed that the injected solvents suppressed the distillation of light bitumen fractions and caused the produced oil in SA-SAGD to become heavier than that in SAGD. Condensate components flowed separately according to their volatilities, and showed different levels of in-situ utilization efficiency and recovery factors. Reservoir heterogeneity tended to suppress the compositional separation by enhancing the in-situ mixing of components. Additionally, the water imbibition outside of a steam chamber was found to be significant in the early stage of SAGD through the experiment and caused the production of oil by water imbibition, instead of by gravity. A water-soluble organic alkali, diethylamine (DEA), was therefore investigated for its potential to enhance bitumen flow through flow experiments

This book was released on 2023-09-25 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive guide to a cutting-edge and cost-effective refinement process for heavy oil Oil sufficiently viscous that it cannot flow normally from production wells is called heavy oil and constitutes as much as 70% of global oil reserves. Extracting and refining this oil can pose significant challenges, including very high transportation costs. As a result, processes which produce and partially refine heavy oil in situ, known as catalytic upgrading, are an increasingly important part of the heavy oil extraction process, and the reduced carbon footprint associated with these methods promises to make them even more significant in the coming years. Catalytic In-Situ Upgrading of Heavy and Extra-Heavy Crude Oils provides a comprehensive introduction to these processes. It introduces the properties and characteristics of heavy and extra-heavy oil before discussing different catalysts and catalyzing processes, their mechanisms and underlying physics, and more. It offers the full sweep of description and analysis required for petroleum and chemical engineers to understand this vital aspect of the modern oil industry. Readers will also find: Detailed discussion of subjects including electron paramagnetic resonance spectroscopy, nuclear magnetic resonance spectroscopy, and more Analysis of both liquid catalysts and nanoparticle catalysts A numerical simulation of the catalytic in-situ oil upgrading process Catalytic In-Situ Upgrading of Heavy and Extra-Heavy Crude Oils is a valuable reference for petroleum and chemical engineers as well as advanced undergraduate and graduate students in related fields.
