Improved naming of Spectres and pipeline tables when a Model is copied to a new database.

6.2.5.8

User Experience

Node pressures and pressure constraints are now prevented from being less than 1 Atm (14.7 psia).

6.2.5.8

Nodes now report pipeline end pressures before the choke (the pressure after the choke can be read from the parent Node's manifold pressure).

6.2.5.7

x

2023-02-06

User Experience

An update with a minor change of behaviour - if a well is outside the VFP table bounds when calculating local reservoir pressure from THP, it is now abandoned.

x

2023-02-01

User Experience

When a well is under pressure control and is using a table production model (spectre) that includes lift-gas rates, these rates are no longer applied as a TGLR constraint.

6.2.5.5

Bug Fix

Fix of some bugs with cost calculations.

6.2.5.4

x

2023-01-29

User Experience

6.2.4.8

x

2022-11-29

Bug Fix

A minor update, completing the reversion of a change to stochastic calculations in A6.2.4.5 that put into sequence incorrectly ordered probability distribution values.

x

2022-11-26

Bug Fix

Fix of bugs with gas injection calculations.

Bug Fix

Reversion of change in A6.2.4.5 to treatment of probability distributions that are in an incorrect order. Now, as before A6.2.4.5, the distribution is omitted from the sums of distributions.

6.2.3.0

x

2022-09-30

Updated Serafim code signing certificate.

x

2022-09-29

Bug Fix

Fixed a bug that occurred with repeated changes of well name.

x

2022-09-07

New Feature

New security options that you can specify during the creation of the .ftrl file to prevent access by unlisted users and to prevent use of copies of the ftrl file.

6.2.1.4

x

2022-08-27

User Experience

Introduced Monte Carlo calculations of the shapes of aggregate probability distributions (e.g. the sum of the individual well reserves), instead of the approximation that these distributions would be normal. This gives results for skewed distributions (e.g. where the upside uncertainty is bigger than the downside uncertainty).

x

2022-08-23

Optimization

Updated the component used with SQLite database (i.e. reading from and writing to.ftrs files).

6.2.1.2

x

2022-08-02

New Feature

Besides the existing method of simply using the pressure of the parent reservoir (with a pressure shift if required), local reservoir pressure can be calculated from the Spectre BHP or THP and flow-rates.

New Feature

Added new Node pressure calculation options to model compressors (compression ratio vs gas flow rate) and pumps (pressure head vs liquid flow rate).

6.2.1.2

New Feature

2022-06-22

Bug Fix

Fixed a bug that gave noise in incremental sales forecasts.

x

2022-06-10

2022-05-31

Bug Fix

Fixed a bug with reordering the list of Forecast in the "Edit Stochastic Calculations" dialog.

x

2022-05-28

2022-05-12

User Experience

Difference Forecasts of two roll-ups now also calculate the differences in incremental sales profiles, as well as the differences in well-head profiles

Bug Fix

Fix of an omission of the calculation of operating days in Difference Forecasts

User Experience

A warning is given in the Session Log when a well or node's flow rates are outside the bounds of the well or node's pipeline (VFP) table and any consequent discrepancies between the linear approximation and the pipeline table are not reported (because any error is as likely to be the result of the extrapolation of the table as of the linear approximation).

6.1.8.14

x

2022-05-04

User Experience

In gas composition variable splits, prior estimates of CO2 fraction are kept and used after shut-ins for the linearisation of the condition that the composition is the same to parent as it is to step-parent (so use of well potentials is restricted to the first Simplex iteration in the first time-step (otherwise, low CO2 facilities with some high CO2 wells could find it impossible to reopen after a shut-in). 

Optimization

When opening a Model, all "SELECT" statements now include "ORDER BY Name" (or other suitable field), to help ensure that successive calculation runs with the same parameters give, as far as possible, identical results.

Optimization

Recursive calculation of Node uptime has been replaced by a non-recursive calculation, reducing some model run times by 25%.

6.1.8.6

x

2022-04-18

User Experience

A minor update - in forecasts that report incremental wells separately, fluid composition is now reported for wells (previously, such reporting was omitted because of an oversight, but this had no effect on calculations).

x

2022-02-12

User Experience

Better notification message if an incremental sales tranche has all its new wells disabled

User Experience

Improvements to the behavior of the new license dialog

Optimization

Improvements to the allocation of incremental sales when the physical wells in the tranche have zero production.

6.1.7.0

x

2022-02-07

6.1.6.1

x

2022-01-22

Bug Fix

A minor update, fixing a slowness that crept in with V6.1.6.0. (The development environment had reset to default an important memory management parameter; the fix includes code to detect and warn about any recurrence).

6.1.6.0

x

2022-01-15

New Feature

Updated with three levels of license: - "Enterprise" with all functionality - "Professional" without pressure, risk and incremental sales calculations in large (>25 wells) models - "Community" - free of charge, but limited to a maximum of 25 wells

Optimization

Improvements to speed-up of reserves reports.

6.1.5.17

x

2022-01-09

Bug Fix

A minor update fixing a problem with the transfer of licensing for a third-party software component to a new development machine (the problem could cause the Node diagram to display "Trial license" text).

6.1.5.16

x

2022-01-05

Bug Fix

Fix of a minor display bug that occurred when a sort was carried out during the initial load of the Well Approval Manager window

Optimization

Removed an occasional change in the Node/Well order in which the linear solver calculations are set up (this could give rise to different choices of priority where there were several wells of equal value)

6.1

x

2021-09-05

Optimization

Use of upper and lower bounds on individual variables in the Simplex calculations. This typically reduces run-times for large (300+ wells) models by 40%

New Feature

Wells and modifications can be grouped into "Activity Groups" of multiple wells/modifications. The Activity Groups can be put into Work Sequences or given start dates and all their members will have their individual start dates shifted accordingly (For example, a well on-stream date can be specified as being 90 days after the drilling of the well).

New Feature

There is new "Load Properties from Excel" functionality that enables you to create new wells, curbs, etc. and read in their properties from Excel in a single step.

New Feature

6.0.3.36

x

2021-07-09

User Experience

Incremental wells are prevented from having abandonment criteria (water-cut criteria gave unexpected results when oil-rate was negative and water-rate was positive).

Optimization

Speed up of filling entity list.

6.0.3.30

x

2021-06-09

Optimization

A minor update that sets FUTURE to use all available CPU groups, as described in https://docs.microsoft.com/en-us/dotnet/framework/configure-apps/file-schema/runtime/thread-useallcpugroups-element Note - this has no effect on machines with only one CPU group (generally only servers with more than 64 logical processors have more than one CPU group).

6.0.3.27

x

2021-06-03

User Experience

A small change in uptime calculations and in forecast output. The update will bring FUTURE's behavior closer to what most users expect to happen with uptime calculations.

6.0.3.26

x

2021-05-31

User Experience

Well inflow performance calculations (i.e. liquid productivity index or gas pseudo-pressure A and F factors) are adjusted for changes in the liquid:gas fractional flow at reservoir conditions, under the assumption of fully segregated flow.

User Experience

Better defaults when gas composition is only partially specified (e.g. just CO2 fraction), to avoid anomalous Z-factors.

Optimization

When the Simplex calculation finds no possible solution, there are improvements to the identification of the lowest node/well that gives rise to the problem

Optimization

Increased margin on THP when trying to ensure that the Simplex calculations allow all wells to be shut-in

x

2021-05-19

Bug Fix

A minor update fixing a problem with the incremental sales calculations.

6.0.3.23

x

2021-05-16

User Experience

The linearization of the reservoir inflow performance curve now ensures that zero flow is feasible (i.e. compatible with the current THP and VFP linearization). This is to prevent the situation that wells are shut-in to prevent a poor quality well from being unable to flow.

User Experience

In line with the FUTURE usage that "oil" = hydrocarbon liquids (including condensate), while "condensate" = that part of "oil" that FUTURE calculates originates from vaporized oil in a gas leg, charts etc. now use "OGR" instead of "CGR" (there is no change in calculations; this is purely a change in naming).

6.0.3.22

x

x

2021-05-12

User Experience

A minor update that applies to both the adaptive and fixed versions, removing small values in incremental sales profiles that are due to noise (in the start period where lower and the upper forecast for the incremental tranche in question should be identical).

Note – For the fixed version, this is also a cumulative update.

6.0.3.21

x

2021-05-10

Bug Fix

A minor update fixing a bug with use of "Save As..." while reading of historicals was still in progress.

6.0.3.20

x

2021-05-08

User Experience

Sharing out of incremental sales of condensate, water and solution gas , when their well-head rate totals for the wells in the tranche are zero, is now done in proportion to well-head oil or gas rate totals.

Bug FIx

Fix of bug with changing tubings.

Bug Fix

Fix of bug with gas-lift calculations in multi-segment wells.

6.0.3.19

x

x

Bug Fix

Fix of a bug with database-writing of uncompressed profiles for difference forecasts.

User Experience

Adjusted date range in the interactive chart for spectres loaded from RSM files that have "YEAR" data rather than "DATE" data (i.e. profiles that begin at date = 0 or 1 Jan 1900).

6.0.3.18

x

x

2021-05-02

Bug Fix

A minor update fixing a bug in the material balance calculations in roll-up forecasts. NB - the bug may have caused errors in incremental sales calculations in models that used material balance pressure calculations.

6.0.3.16

x

2021-04-28

Bug Fix

Lack of a proper error message when wells are created from an Excel list with duplicate entries

Bug Fix

Problems with handling dates in "Edit Table" when the Windows date format allowed single digit day or month entries (e.g. "1/1/2021" instead of "01/01/2021"). Note - this problem had on occasion significant consequences, such as causing changes to well start dates; also, it is not yet known whether the changes (which modify the date format to use "01" in place of "1") in A6.0.3.16 will provide a complete solution to this problem.

6.0.3.14

x

2021-04-26

Bug Fix

Fixed bug with multi-threaded writing of log information to SqlServer.
