Study of the Effect of Fracture Completion Variables on Decline Curve Parameters for Long-Term Production Forecast of Shale Liquids
… of oil and gas reserves throughout the world. Forecasts of future production from these reservoirs based on the fracture stimulation parameters and reservoir properties has led to a better understanding of the duration of important flow regimes and parameters used in production forecasting …

Mechanistic and probabilistic rate-time analysis of unconventional reservoirs
Rate-time analysis is a widely used technique to forecast production in oil and gas production. The geological complexity of shale formations and their ultra-low permeability creates significant uncertainty on the behavior of these wells and their production forecast. This work is divided into two …

Stretched Exponential Decline Model as a Probabilistic and Deterministic Tool for Production Forecasting and Reserve Estimation in Oil and Gas Shales
… models can lead to significantly over-optimistic production forecasts without additional safeguards. Stretched Exponential decline model (SEDM) gives considerably more stabilized production forecast than traditional DCA models and in this work it is shown that it produces unchanging EUR forecasts …

Inclusion of Fracture Skin in Duong’s Model of Rate-Decline Analysis for Fracture-Dominated Shale Reservoirs
Production forecast plays an important role in helping us make rational decisions in face of large uncertainties. Unconventional oil and gas production has followed an accelerated growth trajectory in the US oil and gas industry. Unconventional reservoirs vary significantly in their reservoir …

Probabilistic Oil and Gas Production Forecasting using Machine Learning
… by quantifying the uncertainty of the production-forecasting process, using probabilistic machine learning (ML) techniques. A Bayesian Neural Network successfully modelled a complex shale gas reservoir system (Eagle Ford), generating a production forecast with 5% mean absolute percent …

Managing Financial Risks for Wind Power Producers in Wholesale Electricity Markets
… markets due to the uncertain nature of wind forecasts, day-ahead electricity prices, and real-time electricity prices. In the event of a shortfall compared to the production forecast, the wind generator may have to repurchase power at a higher price in the real-time market. Based on this …

A new optimisation procedure for uncertainty reduction by intelligent wells during field development planning
… the impact of geological uncertainty on the production forecast (Birchenko, Demyanov et al. 2008). This investigation has now been extended to the “dynamic” parameters (fluid contacts, relative permeabilities, aquifer strength and zonal skin). The efficiency of the IWs in reducing the total …

Chemical and physical effects of interaction between oilfield chemicals and formation rocks and integration with sand failure prediction models.
Sand failure may result in the production of formation sand at the same time the formation fluids are being produced. Sand failure occurs when the formation stress exceeds the strength of the formation, which is derived mainly from the natural material that cements the sand grain and cohesive …

Production Analysis in Tight/Shale Reservoirs Via Machine Learning Approaches
… energy mix. The accurate prediction of well production dynamics in these complex formations is a formidable challenge. Traditional empirical and numerical approaches, often fall short due to their inherent simplifications or computational demands. With the surge in data availability from …

Application of artificial intelligence techniques to well spacing optimization in fractured tight reservoirs
… affects the economic performance of oil and gas production operations. Oil and gas field operators over the years have resorted to field trials, surveillance and numerical simulation as the modes of determining optimal well spacing. Although field trials and surveillance are relatively easier to …

Characterization of anisotropy in organic-rich shales: shear and tensile failure, wave velocity, matrix and fracture permeability
… geometry which can eventually improve the production forecast. The measurement of permeability of shale formations is challenging due to both the tight nature of shales and the presence of anisotropic features (lamination and microfractures). As an alternative to pulse decay and crushed …

Forecast of Virginia coal production
This thesis provides a model for forecasting coal production rates in southwest Virginia. A multiple linear regression model is developed for the forecasting process. The model includes six independent variables: Virginia coal price times Virginia coal mining productivity (x₁), Virginia mining …
