Rock Flow Dynamics

October 2018

Key improvements in 18.3

tNavigator kernel: Default settings for grid properties output have been changed from "all data at all time steps" to "at RPTRST time steps". Graphs are still saved at all time steps. Geology Designer: A tool for collective work of multiple users is implemented:

objects can be transferred between projects. Cokriging algorithm and Kriging Variance calculation is available in 3D

interpolation. PVT Designer: Non-equilibrium phase state may be modeled for compositional

models (different rate of gas liberation from liquid and its dissolution).

Assisted History Matching and Uncertainty: quadratic Proxy model may be built from selected model’s variants. Resulting formula of Proxy model is available.

Model Designer: Possibility to load hydraulic fracture parameters in a table form Network Designer: Possibility to create several variants of network and compare

results

Compatibility with previous versions

In simulator: default settings for the amount of results output have been changed. Instead of previously used "all data at all time steps", now grid properties are saved at the time steps according to RPTRST keyword. Graphs are still saved at all time steps.

In simulator: INIT keyword must be specified in GRID section to export initial properties in binary format E1/E3.

In Graph Calculator: syntax of graph aggregation has been improved (no backward compatibility).

In AHM module: models with reservoir coupling option may be calculated (no backward compatibility).

2D maps and horizons can be interpolated using well markers, point sets, horizons, polygons and vertical faults

Point Set attributes with residuals are created


The attribute values can be visualized on 2D

Collocated Co-kriging

Collocated co-kriging can be used to model a property using secondary data (property, 2D map or VPC)


Collocated Co-kriging

The kriging variance can be used as an appreciation of the kriging uncertainty

SVG symbols of wells

Loading of custom symbols for wells is made available Symbols are mapped to wells via codes assigned manually in the Wells Table


Merge Logs

Logs can be merged: 3 merge types


Merge: if the selected logs present points located at the same depth, in the resulting log, these points will be replaced by the values of the last selected log (FCh in this example)

Merge Logs



Overwrite: the last selected log rewrites the resulting one (FCh in this example)

Merge Logs



Ignore: If the selected logs present points located at the same depth, in the resulting log, these points will be replaced by the values of the first selected log

Import well logs in LAS format Module: Geology Designer

The well name can be taken from WELL or UWI mnemonic of the LAS file, or from the las file name

Logs with equal names can be merged, overwritten or renamed (using a number)

The depth omissions can be kept, filled with 0 values or filled with empty values

Display patterns on discrete logs

Patterns can be defined for discrete categories during palettes creation


New palette definition

Display patterns on discrete logs

The selected patterns can be displayed on the Well Section (Log Settings)


Log Settings

Display the uncertainty on logs

The log uncertainty can be displayed on the Well Section (Log Settings)


Log value - Log value * uncertainty range/100

Log value + Log value * uncertainty range/100

Log value

Log Settings

Loading data from database

Wells and well logs can now be imported from a database. This is done via special workflow entries

An example script is available upon request

their properties

parameter of THPRESFT keyword

Module: Model Designer Hydraulic Fractures Settings It is possible to define the parameters Hydraulic Fractures in table form

It is possible to: • Copy the data from the table and insert it into text editor • Insert the data copied from file into the table

Fracture Table is an alternative way to model hydraulic fractures via LGR. In this case it is easier to manage large amount of data comparing to conventional workflow (FRACTURE_PATH → FRACTURE_PLANE → FRACTURE_TEMPLATE → FRACTURE_STAGE → FRACTURE_ARITHMETIC)

Module: Model Designer Hydraulic Fractures Settings Each parameter can be specified in a separate column

• Any number wells can be described in one table

• Multistage Fracturing can be defined: one line of the table corresponds to one fracture stage

• The timestep when the particular fracture stage becomes active can be set

• Fracture Plane for Planar Fractures can be defined by specifying Fracture Half-Length and Fracture Height in the table

Module: Model Designer Hydraulic Fractures Settings Fracture Table can be applied to the model via the special Schedule Rule:

• New Global Rule is available: Enable Fracture Table.

• If this rule is added to the strategy, the properties from the specified Fracture Table (grid and schedule properties) will be added to the model

NCCE is similar to CCE,

except that equilibrium

settles over some finite time,

rather than instantly
