...) and lognormally distributed with mean m p and variance S 2 p The log-transformed cumulative production is expressed as y w,p = lnX w,p , which is normally distributed with mean μ p and variance σ 2 p . The variability of the log of cumulative production of period p across the reservoir...

... The 173 CO 2 EOR projects listed in the 2014 Oil and Gas Journal survey were located in 153 fields (Kootungal, 2014). Even in fields having operating projects, it is useful to investigate the prospects of joint or sequential development of nearby candidate reservoirs. Of the 153 fields listed...

...-normalized rates and material-balance time, lead to less accurate model-parameter determination and thus to less accurate forecasts of future production. We propose a new methodology based on Inverse Problem Theory to accurately forecast performance of a reservoir exhibiting variable pressure and rate...

... the importance of outlier detection and outlining the limitations of currently used outlier detection methods. We then validate our method through synthetic examples generated using numerical models of multi-stage hydraulically fractured wells in unconventional reservoirs. Upon validation we demonstrate...

... Abstract Due to the advent of shale reservoirs as important sources of oil and gas production, there has been a critical need for reliable techniques for forecasting production and estimating reserves from these plays. This work presents the results of a study to determine whether simple...

The integration of risk and uncertainty from the reservoir properties through to stochastic portfolio optimization based on project timing and working interest is a unique solution compared to the "siloed" and disconnected approach...

Before the simulation runs, reservoir characterization represents the complex fracture network (generated by multi-stage...

... level. High decline in productivity and increased operational challenges are common issues for mature fields. Recurrently, lower recovery factors are mainly driven by reservoir characterization uncertainty and management, geological complexity, limited resources and operational efficiency. This paper...

... uncertain quantities. "Uncertainty", "variability", "risk", "probability" are all words that are commonly used in discussions related to the predictions of future events (e.g. oil price), or the unknown outcomes of past events (e.g. reservoir properties). The purpose of making such predictions...

... Abstract Facilities decisions are often disconnected from anticipated reservoir performance. A frequent result of this disconnect is operating reservoirs in a sub-optimum manner to protect surface facilities that have inadequate strength. This paper will review the facilities decisions...
