This book was released on 2021-04-15 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rate-transient analysis (RTA) is now one of the most important methods for reservoir and hydraulic fracture characterization used in the petroleum industry for unconventional gas and light oil reservoirs. RTA is also used as the basis for generating a production forecast. However, RTA is based primarily on analytical models that were developed for conventional reservoirs with many simplifying assumptions that often don't apply to unconventional reservoirs. Unconventional Gas and Light Oil Reservoir Rate-Transient Analysis: Volume 1 - Fundamentals delivers a critical knowledge gap to help practicing reservoir and production engineers understand the unique differences in rate-transient analysis for today's unconventional reservoirs. Starting with the fundamentals, engineers first understand the basic flow regimes and analysis methods along with the unique reservoir properties of unconventional assets. Then, the chapters progress to more advanced topics such as how to modify and apply RTA methods for each instance of shale oil/gas, coalbed methane, and tight shale oil/gas along with transforming these modified methods into higher quality production forecasting, with emphasis on analytical and semi-analytical methods. Supported by many real-world field examples covering both hydraulic fracturing and unconventional reservoirs to learn from with questions and answers to practice, Unconventional Gas and Light Oil Reservoir Rate-Transient Analysis: Volume 1 - Fundamentals supplies today's petroleum engineers with a more intelligent approach to today's more complex reservoirs. Improve reservoir flow-rate workflows specific to unconventional oil and gas reservoirs as well as complex hydraulic fracturing projects Authored by leading researcher and expert in unconventional reservoir RTA Generate stronger production forecasts with guidelines and field examples on how to deal with data uncertainties, poor data quality, and operational upsets

Available in PDF, EPUB and Kindle. Book excerpt: Unconventional gas reservoirs, such as tight gas and shale gas, appear to have great potential to supply future demand for hydrocarbon. Economics of these reservoirs are tied closely to the performance of multi-fractured horizontal wells (MFHWs), which is the most direct indicator of stimulation effectiveness. Thus, greater understanding and analysis of the factors affecting performance of MFHWs are critical for the efficient exploitation of such reservoirs. Hydrocarbon production data analysis (PDA) techniques have been commonly used to characterize hydraulic fracture (HF) and, ultimately, to evaluate hydraulic-fracturing jobs. Recent studies have shown that rate transient analysis of flowback data can also provide early insight into HF attributes. While PDA methods seek long-time production data, flowback analysis can be conducted using early water and gas production data obtained immediately after the completion of stimulation jobs. However, in comparison with the long-term hydrocarbon production period, the physics of the process is more difficult to capture during flowback production because of its short duration, at which one or more flow regimes may occur. In addition, the flowback flow system could be single- or two-phase, depending on reservoir type. According to reported field data, single-phase flowback can be observed in tight sands, but two-phase flow is expected in the case of shale gas. Although various mathematical models have been proposed to analyze single-phase (water) and two-phase (gas and water) flowback data, analytical models for interpretation of data are still at an early stage of development. The objectives of this study are first to reproduce the relevant analytical models available in literature and understand their advantages and limitations; then, to develop single-phase and two-phase analytical models capable of predicting HF attributes such as fracture half-length and fracture permeability using early water and gas production data. In this study, a set of numerical simulations was conducted using CMG (IMEX) to examine the capacity of available mathematical models. It was found that most of the single-phase flowback models in the literature are accurate only under pseudo steady-state conditions, where a boundary-dominated flow regime with a constant production rate has been established. Another limitation of current models is that they can only estimate one fracture attributes: kf or xf. Knowing the shortcomings of current models, I developed a set of analytical models for both single- and two-phase systems, which were validated against numerical simulations. The single-phase model can closely estimate HF attributes, such as permeability and half-length under constant pressure as well as constant flowrate condition, for both transient and boundary dominated flow periods. Furthermore, I extended the developed single-phase model to variable bottomhole conditions by employing superposition principle. In the case of two-phase flow system, I developed an analytical model under fracture depletion mechanism for both early gas production (EGP) and late gas production (LGP) periods. In the case of EGP, gas flux from matrix to HF is assumed to be negligible. Comparisons of numerical results with those obtained from the analytical model show that the developed two-phase model for EGP can accurately predict fracture attributes. In the case of LGP, a coupled model is developed to include the effect of gas influx from matrix to HF on flowback data, where a uniform pressure decline rate is assumed in fracture-matrix system. The two-phase model has the advantage of linear behavior of water properties and avoids the computational complexity. With typical Barnett shale properties input in the numerical simulation, the analytical model can accurately estimate fracture attributes within a 10% error margin. Sensitivity analyses of fracture conductivity and initial water saturation in fracture have been conducted to illustrate the validity of two-phase flowback model applied in LGP. The results reveal that, within the physical range of fracture conductivity and initial water saturation, the two-phase flowback model can accurately evaluate fracture attributes. However, the model is more accurate for cases with smaller fracture conductivity and higher initial water saturation in fracture.

Download or read book Rate Transient Analysis and Completion Optimization Study in Eagle Ford Shale written by Chaitanya Borade and published by . This book was released on 2015 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of well performance data can deliver decision-making solutions regarding field development, production optimization, and reserves evaluation. Well performance analysis involves the study of the measured response of a system, the reservoir in our case, in the form of production rates and flowing pressures. The Eagle Ford shale in South Texas is one of the most prolific shale plays in the United States. However, the ultra-low permeability of the shale combined with its limited production history makes predicting ultimate recovery very difficult, especially in the early life of a well. Use of Rate Transient Analysis makes the analysis of early production data possible, which involves solving an inverse problem. Unlike the traditional decline analysis, Rate Transient Analysis requires measured production rates and flowing pressures, which were provided by an operator based in the Eagle Ford. This study is divided into two objectives. The first objective is to analyze well performance data from Eagle Ford shale gas wells provided by an operator. This analysis adopts the use of probabilistic rate transient analysis to help quantify uncertainty. With this approach, it is possible to systematically investigate the allowable parameter space based on acceptable ranges of inputs such as fracture length, matrix permeability, conductivity and well spacing. Since well spacing and reservoir boundaries were unknown, a base case with a reservoir width of 1500 feet was assumed. This analysis presents a workflow that integrates probabilistic and analytical modeling for shale gas wells in an unconventional reservoir. To validate the results between probabilistic and analytical modeling, a percent difference of less than 15% was assumed as an acceptable range for the ultimate recoverable forecasts. Understanding the effect of existing completion on the cumulative production is of great value to operators. This information helps them plan and optimize future completion designs while reducing operational costs. This study addresses the secondary objective by generating an Artificial Neural Network model. Using database from existing wells, a neural network model was successfully generated and completion effectiveness and optimization analysis was conducted. A good agreement between the predicted model output values and actual values (R2 = 0.99) validated the applicability of this model. A completion optimization study showed that wells drilled in condensate-rich zones required higher proppant and liquid volumes, whereas wells in gas-rich zones required closer cluster spacing. Analysis results helped to identify wells which were either under-stimulated or over-stimulated and appropriate recommendations were made.
