Well Selection2
Well Selection

Well Selection permits evaluating grid properties’ distribution within the wells region and them neighborhood.

IJK Block - Oil Quantity
IJK Block

“IJK Block” is a Kraken’s process that allows selecting the desired range of coordinates in the Main Grid. It is a convenient tool to analyze and compare different regions separately.

WORWC
Cross Plot Window

Kraken allows the user to create cross plot in order to confront parameters and evaluate how they are correlated. Special applications include WOR forecasting as a way to predict cumulative oil reserves.

Plane - Cut
Plane

A section plane creates a sectional view that shows internal details that cannot be seen from the outside perspective. Kraken has a process called “Plane” which allows setting clip-, cut-, and planes between two wells.

NNC
Non-neighbor connections (NNC)

In the presence of faults, physical neighbors no longer coincide with logical neighbors which lead to the creation of non-neighbour connections (NNCs).

InspectorCell
Inspection

Kraken allows the user to investigate a grid block through inspection by assessing the properties’ values. Different inspections are useful to compare how values change throughout the grid cells.

Grid Conversion - Cell Centered
Grid Conversion

Reservoir grids result from reservoir characterization and can be constructed for one-, two- and three dimensions as well as different geometries. Kraken has a capability which enables converting the original grid to another grid types.

Histogram
Histogram

A histogram is a useful graphical method that shows data frequency distribution. It can be applied to a determined property in a reservoir grid, especially due to the enormous number of cells.

3D Visualization of grid properties and faults

Kraken 3D visualization capabilities allow Reservoir Engineers to visualize faults, non neighbor connections and pinch-outs, while coloring the cell faces with static or transient properties over time.

Ternary Saturation
Ternary Saturation Example

Kraken 3D features includes the simultaneous visualization of water, oil and gas saturation, displaying them in a ternary color-scale.

Oil and Water Streamlines
Streamlines

Streamlines allow the engineer to visualize the areas drainage areas and fluids’ preferential paths as well as evaluate the efficiency of producers/injectors. Kraken is able to recreate the streamlines based on fluids flow.

watercut
Water Cut Plot and 3D visualization

Kraken allows the simultaneous visualization of properties at the reservoir grid and the curves in the wells, allowing the engineers to correlate the phenomena happening within the reservoir with the response of the wells.

plane cut 2 wells
Plane cut between 2 wells

Two wells in the same reservoir might influence each other. Kraken has a plane cut mode in which two wells are selected and properties can be visualized over time in order to better understand those possible influences.

DCA_Analysis
Decline Curve Analysis (DCA)

Production trends can be estimated using different equations, such as Exponential and Hyperbolic decline. Kraken has an interface to import historical data and perform such calculations as well as create scripts to perform regression analysis to predict future production.
