The application of sensitivity analysis to reservoir simulation

  Reservoir simulation involves the mathematical manipulation of a significant amount of information, most of which is subject to uncertainties due to factors such as insufficient measurements, lack of accuracy and spatial heterogeneities, as previously discussed. Consequently, it is imperative to quantify the impact of these parameters’ variations on the simulation workflows (modeling, analysis and..

Risk and uncertainty in petroleum exploration

It is well known and documented that exploration of hydrocarbons is inherently a high-risk activity given a large number of uncertainties that may be present at any particular stage. The most common uncertainties are related to geological features such as structures, seals, and faults. On the other hand, economic analyses present uncertainties related to costs,..

Upscaling: Building a reservoir simulation model

In recent years, continuous improvements in computing and software technologies have considerably enhanced several aspects of reservoir simulation techniques. Simulation runtimes have sharply decreased due to advancements in hardware and processing power. In spite of this, the level of detail built into a geological model continues to exceed the current computational capabilities. Typical reservoir simulators..

Production curves visualization just got easier

Reservoir Engineers analyze production curves quite frequently as part of the daily tasks. This ranges from the definition of a recovery strategy for an exploratory field to the surveillance of a reservoir with years of production. These curves may come from either a reservoir simulation or field measurements and  their analysis can provide invaluable reservoir knowledge. In..

Creating Reservoir Engineering Reports

Kraken provides different ways to create custom reservoir engineering reports for daily tasks. Such reports can be customized through the following workflows: 1. Use Ctrl+C for putting a snapshot of the currently selected window (plot or 3d window) in the clipboard (which may be later pasted in Word or any other program through Ctrl+V) 2. Create RTF, PDF..
