Version 0.5.3

Added

• #425 Added functionality to load production data from CSV file. Changed position of observation vectors entry in configuration file (now one level higher, same level as simulation and database in data_source entry).
• #417 Added functionality to history match dissolved salts (TDS) in produced water.
• #404 Added possibility for regional multipliers for permeability, porosity and bulkvolume multiplier. Current implementation allows for defining either one global multiplier, or a regional multipliers based on a region parameter extracted from an existing simulation model (typically FIPNUM, EQLNUM, SATNUM etc). The regional multiplier will be in addition to the per tube multipliers. New keys in config yaml are: porosity_regional_scheme (global, individual or regions_from_sim), porosity_regional (define prior same way as for other model parameters) and porosity_parameter_from_sim_model (name of region parameter in simulation model). The same three keys exists for permeability and bulkvolume_mult.
• #383 Added option to either define a prior distribution for KRWMAX directly by using krwmax in the config yaml, or to let KRWMAX be calculated as KRWEND + delta. To do the latter, set krwmax_add_to_krwend to true, and then the prior distribution definition in the config yaml for krwmax will be interpreted as a prior distribution for the delta value to be added to KRWEND to get the KRWMAX.
• #386 Expose FlowNet timeout to user.
• #356 Added option to distribute the original volume over the FlowNet tubes in a Voronoi-diagram style. I.e., areas with a high density of FlowNet tubes get a lower volume per tube.
• #379 Added option to let SWCR be calculated as SWL + delta, instead of providing the prior distribution for SWCR directly. To do this, set swcr_add_to_swl to true, and then the prior distribution definition in the config yaml for swcr will be interpreted as a prior distribution for the delta value to be added to SWL to get the SWCR.
• #372 Added option to let the additional flownodes initially be placed within the original volume rather than within the convex hull of the real wells. To do this set place_nodes_in_volume_reservoir to true.

Fixes

• #403 Fixes bug in generation of THPRES keyword for OPM Flow
• #391 Fixes bug in generation of yaml files for visualization in Webviz.
• #372 Fixes bug of hull_factor not actually being used for placing additional nodes outside the perforations.
• #374 Fix for memory leak in result plotting script.

Changes

• #401 When distributing volume from a simulation model to a FlowNet, the voronoi_per_tube distribution method now distributes first to tube cells, sums these values, and then redistributes the summed tube volume equally over the tube cells.
• #396 When using scheme regions_from_sim for equilibrium regions, the user can supply which region to base the generation of FlowNet model's EQLNUM parameter on. The default region is EQLNUM, but other region parameters (such as FIPNUM or SATNUM) can be used by setting region_parameter_from_sim_model for equil in the config yaml file.
• #392 When using scheme regions_from_sim for relative permeability, the user can supply which region to base the generation of FlowNet model's SATNUM parameter on. The default region is SATNUM, but other region parameters (such as FIPNUM or EQLNUM) can be used by setting region_parameter_from_sim_model for relative permeability in the config yaml file to e.g. EQLNUM.
• #383 KRWMAX now defaulted to 1, but exposed to used. Previously it was hard coded to 1.
• #386 Increase default timeout from 900 s to 3600 s.
• #363 Drop Python 3.6 support.
• #361 Adding numpy code for SWOF/SGOF table generation, instead of using pyscal, to improve computational efficiency when running many realizations with many SATNUM regions. Keeping pyscal in the tests for comparison.

Version 0.5.2

Added

• #365 Analytics workflow now also available for prediction mode.
• #351 Added simple plotting tool that allows for plotting of FlowNet ensembles and observations.

Fixes

• #365 Fixes bug where the parquet parameters file would not be saved for iterations larger than 9.

Changes

• #365 Structure change of the code. Moved all forward models called from ERT to a seperate folder ert/forward_models. Scripts moved: delete_simulation_output, save_iteration_parameters, iteration_analytics, render_realization and flow_job.
• #347 Additional flow nodes is now allowed to be either a list (equal length of number of layers) or a single integer (which will be split over the layers according to volume of concave hull).

Version 0.5.1

Fixes

• #346 Fixes bug where the analytics module would fail for iterations larger than 9 (i.e., iteration number with two or more digits).

Version 0.5.0

Added

• #341 Added option to add a min permeability threshold for which tubes are deactivated when the permeability is below this value.
• #305 Functionality of generating seperate flownets per layer is enabled, additional nodes are split between the layers according to the volume of concave hull of the layers.
• #298 Connections between (well)nodes that go through non-reservoir are now removed. Angle threshold export to user.
• #296 Adapted perforation strategy to allow for layering + bug fixes in the 'multiple' and 'multiple_based_on_workovers' perforation strategies.
• #284 Added the option to specify cumulative phase rates as observations (WOPT, WWPT, WGPT, WGIT, WWIT)

Fixes

• #339 Fixes bug where the analytics module would fail when a well name filter was supplied.
• #325 Fixes bug where the analytics module would repeat the 8th iteration analytics for iterations larger than 9.
• #256 Fixes issues with duplicate names in hyperopt by using the full path in yaml for hyperopt parameter names.
• #272 Adds resampling of observation dates at requested frequency by finding nearest date among existing observation dates (i.e., no interpolated dates added)

Changes

• #342 Additional flow nodes are now a list in the configuration file, which allows for variation in the number of addtional nodes from layer to layer.
• #337 You can now add multiple analytics workflows in your FlowNet config. This is also a breaking change in that it requires you to change the ert.analysis keyword to being a list.
• #322 RSVD input through csv files can now be done either as one table used for all EQLNUM regions, or as one table for each EQLNUM region. The csv file needs a header with column names "depth", "rs" and "eqlnum" (the latter only when multiple tables are defined).

Version 0.4.0

Added

• #234 Added mlflow in combination with hyperopt which allows running flownet in batch to explore and optimise hyperparameters.
• #221 For traceability and reproducibility, the FlowNet configuration file is now automatically copied to the output folder. The content of 'pip freeze' is stored in the file 'pipfreeze.output' in the output folder.
• #220 User can now provide the historical control mode in the production wells and control mode/target in the injection wells. One value for each, applied to all wells.
• #199 Added the possibility of defining a 'base' value for all parameters related to relative permeability. This provides the opportunity to interpolate between three relative permeability models. All the 'min' values will be used to construct a pessimistic or low model, the 'base' values are used for a 'base' model, and the 'high' values are used for an optimistic or high model value. The history matching can then be done with only one (two for three phase models - oil/water and gas/oil interpolated independently) relative permeability parameter(s) per SATNUM region.
• #197 Added opening/closing of connections based on straddling/plugging/perforations through time. This PR also adds a new perforation strategy multiple_based_on_workovers which models the well connections with as few connections as possible taking into account opening/closing of groups of connections.
• #188 The possibility to extract regions from an input simulation model extended to also include SATNUM regions. For relative permeability, the scheme keyword can be set to 'regions_from_sim' in the configuration file.
• #189 User can now provide both a base configuration file, and an optional extra configuration file which will be used to override the base settings.
• #155 Adds reading of simulation 'well logs' to condition the priors of permeability and porosity based using kriging

Changed

• #199 Removed deprecated parameters in pyscal ('krowend', 'krogend') from config file. Added 'kroend' to config file.
• #228 FlowNet is now pip installable without any dependency compilations (also the custom ERT forward model running Flow is installed automatically). Note that any simulator part of configuration files need to be removed.

Version 0.3.0

Added

• #160 Adds the possibility to extract regions from an existing model when the data source is a simulation model. For equil, the scheme key can be set to 'regions_from_sim'
• #157 Adds a new 'time-weighted average open perforation location' perforation strategy called time_avg_open_location.
• #150 Adds this changelog.
• #146 Added about page to documentation with logo of industry and research institute partners.
• #138 Print message to terminal when the schedule is being generated instead of utter silence.
• #134 Egg model added in CI.
• #128 Add possibility to use the original simulation model volume as volumetric constraints for adding new nodes as well as the option to set a maximum connection length.
• #115 Documentation of the preliminary Egg model results have been added.
• #104 Adds a new FlowNet logo.
• #98 Rock and Aquifer keywords are now allowed to be optional parameters.
• #95, #97 Relative permeability and training_set_end_date are now allowed to be optional. The training set definition will be checked upon parsing the configfile.
• #90 Running the analysis workflow is now optional.
• #77 Adds a warning message when the WSTAT keyword is not present in the original simulation data deck. The default status is OPEN.

Fixed

• #141 Fixed misplacement of WCONINJH target (RATE / BHP). The default RATE is however still always used.
• #137 After having moved all example data to flownet-testdata the examples folder had no use longer. Removed.
• #136 The ERT queue name was wrongly required in the config file. It is now allowed to have no value.
• #119 Workaround for equinor/libres#984
• #92 Fixed problem where the last production well would not correctly be shut.
• #88, #106, #108, #110 Fixed bugs in parsing the config that were a result of a changed behavior in configsuite where an item that has subitems with subitems, no longer can be tested for all None as the subitem with subitems in fact is a NamedDict with all None.
• #89, #91, #99 Updates and fixes in git workflow.
• #81 Various bugfixes in the analysis workflow are now solved.
• #75 Resampling via the config path is no longer supported. This PR removes also the resampling option from the config file parser.

Changed

• #147 The observation uncertainty now only needs to be specified for the vectors that are actually used in the conditioning. This PR also adds possibility of defining uncertainty for WWIR and WGIR into the flownet config YAML.
• #132 The observation uncertainty, used for conditioning models, is now exposed to the user via the configuration file instead of hidden in the observations.yamlobs.jinja2 template. This PR also introduced a wider usage of passing around the ConfigSuit.snapshot.
• #128 Simulation models and configuration files used in CI are now coming from flownet-testdata and are thus no longer an integral part of the flownet repository.
• #125 AHM and prediction subprocess call are now being performed through a common run_ert_subprocess function call.
• #123 Significant speed-up of the fault raytracing by limiting the ray tracing to the bounding box of individual connections instead of ray tracing over all triangles of all faults for each connection.
• #111 Phases present in the FlowNet model are to be set manually in configuration by the user.
• #63 The default simulator name has now been changed to Flow.
• #80 FlowNet now supports relative paths in the config file.
