EUR database: b factors have been constrained between 0 and 2 to provide reasonable EURs
EUR database: Inclining production trend is no longer modeled - any months prior to the month of maximum production are linearly interpolated from that maximum. This linear trend is for graphical purposes only and is not used in calculation of EURs
EUR database: An EUR is calculated only if there is a minimum of 6 months of overall declining production data. Multiple segments may be identified, if there is a series of at least 5 production values per segment
EUR database: The model carries out a 'goodness of fit' test that throws out bad model fits in order to provide quality EUR values
Added the ability to show/hide/reorder table columns. Workspace must be saved to retain customization. Export Table will honor column customization, Export Wizard will deliver the full set of attributes in a standard order.
Scatterplot was enhanced to include color-by and size-by options.
The full list of DI Desktop EUR attributes was added to the Production Table. A few of the attributes are now available in the scatterplot and layer symbology. These are entitled to accounts with DI Analytics, DI Engineering, or an EUR add-on subscription.
Section, Township, Range, Abstract, Block, Survey were added to the Production table and are available as filter options
The Cumulative Production record (F) was added to the 298 export files.
Duplicate Trajectories were removed.
Duplicate Well Tests were removed from the Well Card.
Defect Fixes
Added back the lat/long columns to directional survey export.
Old Workspace is now working when grouping is applied.
Application-level entitlements are now enforced in the Gallery. Applications that a user is not entitled to will no longer be accessible. There will be a lock icon shown with a description of the application and message stating how to gain access to the application.
Well Data and Exports: New Wells table with 14-digit identifiers indicating wellbore and completion number. Well results can be filtered, styled on the map, and exported.
Well Data and Exports: Completion data are available as attributes in the Wells dataset for customers with DI Engineering or who are otherwise entitled. Completion detail is available to DI Basic subscribers on the Well Card.
Well Data and Exports: Tabs for Completion, Well Tests, and Formation Tops were added to the Well Card.
Well Data and Exports: Well and completion attributes were added to the scatterplot options.
Well Data and Exports: Well and completion attributes were added to Grouping and Aggregating tool and the Comparative Group Chart.
Well Data and Exports: Decline Curve Analysis can now be launched for filtered entities in either the wells or production tables.
Well Data and Exports: New option to select data with a custom polygon (in addition to filtering by polygon).
Well Data and Exports: DI e298 export for Production data. Both fixed width (298f) and comma delimited (298c) versions are available.
Well Data and Exports: DI e297 export for Well data now includes expanded well header information as well as Well Test, Perforations, and Formation Tops. It still contains directional survey information. Not all attributes will be recognized by all software platforms however.
Well Data and Exports: Production table now features 14-digit API numbers except for lease level production.
Decline Curve Analysis: If there is an active well or production selection DCA will launch with the selected entities as opposed to the full filter result.
Decline Curve Analysis: Well count was added to the hover text on the Type Curve.
Decline Curve Analysis: Terminal decline options were expanded and can be applied to any model type.
Decline Curve Analysis: New histogram for “Months to EUR” or “Months Remaining to EUR” when “To Economic Limit” is selected.
Decline Curve Analysis: Now displaying the correlation coefficient as curve fit metric instead of sum squared errors.
Decline Curve Analysis: Added layer controls to the relevant data components of the Explore Panel.
Scouting Reports and VirtualScout: Permits were added to VirtualScout.
Scouting Reports and VirtualScout: Scouting Reports created with the DI Mobile app post to the Activity Feed and are displayed to Drillinginfo users within the same company.
Scouting Reports and VirtualScout: All Scouting Reports for a company can be exported to a csv file.
Scouting Reports and VirtualScout: Filters were added to the Activity Feed to more easily find notifications of interest.
Entities styled in Layer Symbology can now be customized. For example, select individual operators as opposed to the top X.
Grantor was added to the Legal Lease and LandTrac Lease symbology options.
Changed map layer behavior so data layers only turn on automatically if their filter has changed.
Oil EUR and Gas EUR were added to the Production Table (previously just in export).
Active data selections are now saved with a workspace
Defect Fixes
Corrected how the Arp’s initial decline parameter was being calculated.
Chrome exports can now be downloaded if a comma is present in the export name.
Historical Prod/Type Curve charts and filter by map – “Daily” selection now sticks when the map is zoomed or panned – no longer reverts to Monthly.
Bottom hole lat/lon in the Well Card is fixed.
Changed TX Allocated Production checkbox to be more recognizable.
Added icons to indicate when a user is not entitled to a particular data set, attribute, or export.
Pre-calculated EURs - Effective today, Drillinginfo is now providing pre-calculated EURs using its own internally developed Decline Curve Analysis engine. We are very happy with the overall quality of the EURs calculated by our new engine and having internal control of the entire process is a major benefit moving forward. Be on the lookout for a more detailed white paper comparing these internally generated EURs to those previously calculated through a third party provider.
[Oklahoma] - Oklahoma production is now supplemented with purchaser/transporter tax reports containing gross monthly oil volumes gathered from oil PUNs. This resolves issues regarding OTC oil production volumes where entire months of production were missing and reduces the reporting lag of oil production from 9-12 months to about three months. The result from this change will be available in DI Desktop, Production Workspace, DI Analytics, and DI Activity Maps.
