Release Notes

DI Transform

Enhancements / Updates

• Decline Curve Analysis (DCA) - Model monthly production (flow) data with decline curves to forecast remaining reserves and estimated ultimate recovery (EUR). DCA provides automatic curve fitting using Arps, Duong, Stretched Exponential, Logistic Growth and Power Law decline curve models. Fit curves on individual well production streams or build a type curve based on aggregated time normalized data from a collection of wells. Shown below, known well production is in blue, best fit model detects multiple decline segments displayed in green, and data outliers are flagged in red. Forecast has been performed showing P10, P30, P50, P70, and P90 production probabilities in white.
• Well Interference – New options include: 1. “Current Spacing” under Well Spacing Options > “Use date” This will allow calculation of distances for all well pairs regardless of whether or not the wells have any date scalars. 2. An increase from 2 to 5 for the number of well pairs that will generate for any given Interference well.
• Well Targeting – Cursor position readouts include X, Y, MD, TD, ELEVATION, TVD, TVDSS. New calculations include the average isopach and distance proportion the well spends in zone. “Measurements Mode Tools” work with the Structural Model so fault dips and displacements display with layers in the Well Targeting cross section view as shown below. The view is displaying Wellbore to Fault Thickness values.
• Data Generation Wizard - Consolidates many of our data extraction and data creation workflows into a unified wizard. Each tool now has a common user interface, supports batch operations, summary reporting tools, progress reporting, list generation and .csv export. Most of our existing extractions have improved workflows when using the Data Generation Wizard, but the legacy versions are still available in the menus. There are also new tools available only in the Data Generation Wizard.
• Data Generation Wizard > Well/Zone Scalars > “Create ‘Net Thickness’ Scalar from Indicator Log” populates sum in zone values to the Zone tab in the Well Properties Viewer. Map the scalar values in Basemap (shown below). Note: Import indicator logs, or generate indicator logs in the Log Calculator or in MVStats classifications. The discrete step values in the indicator logs are the basis for the Net Thickness calculations.
• Data Generation Wizard > Zones > “Create ‘Net Intervals’ from Indicator Log” populates values to the new Net Intervals tab of the Well Properties Viewer. Display the Net Intervals in 3D Depth Scene (shown above) for comparison with wellbore-related items.
• Data Generation Wizard > “Zones” options implement user requests to create Zone Intervals as follows:
• Create Geologic Zones from Tops: 1. top to top 2. top to base of well 3. KB to top 4. KB to base of well 5. top +/- X 6. base +/- X
• Create Completion Intervals from Depths 1. MD to MD 2. TVD to TVD 3. MD to TVD 4. TVD to MD
• Create Completion Intervals from Perforations 1. single to one 2. multiple to one
• Create Horizontal Sections 1. inclination
• Data Generation Wizard > Tops > “Create Tops from Horizons” lets users create a new top pick on any wellbores intersecting the specified horizon. Note: When using time horizons, there must be a default well velocity set to domain convert the wellbores.
• Data Generation Wizard > Microseismic > “Extract Seismic to Microseismic” extracts properties from seismic volumes to microseismic events.
• Data Generation Wizard > Microseismic > “Create Elapsed Time Properties” adds the capability to plot microseismic events by relative time in crossplots, so that event stages can be stacked (such as R-T plots of radial distance vs. time).
• Tops - Migration of project databases to 5.2 will change tops with prior set colors to green. Select Wells > Top Alias Manager to reset the top colors.
• Tops – Changes to Tops include easier creation, coloring, and picking. Select Top colors in the Top Alias Manager, and the colors correctly apply in cross sections and scenes. Cross Section supports top picking with a simplified interface for creating new tops. Both Tops and Top Aliases still post in cross sections; however, Tops are picked on logs.
• Tops - Delete top picks from a 3D Scene by selecting the “Delete well picks” icon and then left-click the top once. In Cross Section, [Shift+left-click] the log to relocate the pick, or right-click the log and select “Delete This Top.”
• Mapping – New mapping options include 1. Storing map parameters to recreate or update layers using original parameters and data. To access the feature, right-click a horizon version in the Data Tree and select Mapping. Note: Horizon versions created in prior versions of Transform lack the stored information to support updating. 2. Map microseismic event properties. 3. Trim color fill in the grid to data points or user-created regions. 4. Map multiple data sources having similar property types. In the screen capture below, the Add button adds tabs for multiple data sources. The two source tabs shown are for the Well Log mnemonics GRD and GR.
• Mapping – New Outlier Analysis identifies and provides removal capability for outlier data points. One use is to QC auto-top picks. The Student T test detects outliers in irregularly distributed spatial data sets by locally adaptive and robust statistical analysis and GIS. GIS 2001 Vol 15, NO 8, p 721-751. Application of the outlier detection is shown in the screen capture below.
• Mapping – Create special heat maps on most data types including point sets and microseismic events.
• Basemap – Basemap supports adding “ArcGIS service Layers” and WMS type Portal layers. Shown below are pipeline and lease map layers from the DI ArcGIS server
• Well QC KB - The interface now has “Well List” and “Find” option
• Wellbore Interval Zone lists - On the Wells menu, select “Create Wellbore Interval Lists” to create the feature. “Style” (color) the intervals by list in 3D Scene.
• Extractions - Extract properties of microseismic events to well or zone scalar values using the Data Generation Wizard
• Mapping - Create Heat Maps on events and map properties of microseismic events.
• Efficiency - More efficient handling of microseismic properties to reduce latency in 3D Scenes and Sessions
• MVStats - Save and reload MVStats models to facilitate working with the same views, settings and data at a later time. Consistency has been improved across MVStats. Well Data Analysis has been replaced by Data Analysis/MVStats views and Seismic and Well Log Data Analysis has been moved to Data Analysis > Legacy. MVStats enhancements include: creating new features such as well attributes, well logs and seismic properties from predicted attributes; data table in each MVStats algorithm showing which data samples have been used in calculation, along with easy export; refresh buttons allowing syncing data with correlation table, updating filter summary and automatic recomputing of the model; outlier removal icon in the attributes panel toolbar and removed outliers available in global data filters; any filters applied to the MVStats correlation table are displayed on top of each algorithm tab when the MVStats model is computed; quick cloning of algorithm tab with a simple right-click; in Hierarchical classification, table facies assignment will be available as a right-click option and a menu item to remove assigned facies in unsupervised and hierarchical classification. In both Unsupervised and Hierarchical classification, double-clicking the cluster in the class table will bring up a bar chart, which shows the centroid value of each class, for each attribute
• Data Analysis – Data table enhancements such as direct copy (Ctrl+C) and paste (Ctrl+V) from the table for easy export, checkboxes to make selection easier and more obvious, icons to hide all N/A values and to add/remove columns, and search functionality in data tables.
• MVStats NLR – The capability to crossplot predictor variable vs. response variable associated with the Monte Carlo simulations for Non-Linear Regression models.
• Templates - From the Help menu, access the directories for Well Log Templates and Import Templates.
• Export - Export Zone Intervals
• Well Survey Import - Import of well deviation surveys no longer creates a duplicate first row nor a last row without fractionally increasing the depth value. The menu option, Tools > “Inspect and Cleanup Wellbore Geometries”, will clean up duplicate rows in existing surveys. Also, the first survey row now accepts non-zero values for azimuth and inclination.
• Production Import - Improvements to the production time series importer include options to map columns to Custom Properties or to Production Rate Properties or Production Volume Properties. Use the new unit options of m3/month, mcf/month, bbl/month and gal/month. Also, it is possible to abort the import after getting the message “Samples will be skipped.”
• Documents - Better documentation for the Distance to Fault feature is now in the Brief Topic “Extract Distance to Faults along Wellbores.”
• Usage Tracking has been implemented to help guide DI Transform development. No personal information is collected. It only tracks when a user opens, closes, activates, or deactivates part of DI Transform.
