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,..
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..
The Reservoir Engineering has an extensive bibliography, including textbooks and published articles. As it comprises various themes of high complexity, it is always recommended searching for reliable references, most of the times provided by distinguished professionals in the oil industry. This post aims to indicate some of the best textbooks related to this area. Subjects..
This a new post of our series of publications in Kraken’s blog related to Reservoir Engineering. This article is to briefly introduce the reader to the concept of reservoir management and its role in developing a production plan. As discussed in this previous post, numerical simulation has become an indispensable practice to ensure good performance at..
This is the first of a series of posts related to reservoir engineering topics in Kraken’s Blog. The reader can expect articles related to reservoir engineering and various simulation software applications. Other themes such as petrophysics, management, and curve analysis will also be discussed. This first post provides an overview of Reservoir Simulation and highlights..
ESSS is pleased to announce the latest release of Kraken, our reservoir simulation data analysis tool. This new version (2.4.0) includes the following features: Native 2D visualization of reservoir sections in IJK directions: this new visualization mode allows the user to inspect a layer section in a specified direction of the reservoir simulation grid. For example, when..
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..
Last September ESSS and EnginSoft UK, our partner in Europe for distributing Kraken, presented at the event Using Analytics to Improve Production, organised by the Digital Energy Journal, in Aberdeen. The event mainly discussed how analytical techniques can be used to better understand field behaviour and increase production without necessarily increasing costs and investments…
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..
At Kraken 2.0.58 a new tool was presented: the Solutions Comparison tool. Now on Kraken 2.0.59 some issues about GUI and usability were fixed. GUI changes Buttons were repositioned and properly identified to make it easier to understand the purpose of each GUI component. Adding columns Different from the previous version, a new GUI was..
