Legacy XDIAG 1.42 Fixlist

Note: Release prior to 3.x are no longer supported. However, Release 1.4.2.6 will continue to be available for download for customers who have older pre-Windows 2000 operating systems.

Version 1.4.2.6 (released 10 July 2003)
Fixed bug so it now allows loading of NABLA ".dat" files that include a blank line before the counterbalance data.
When opening a new case or a dynamometer file that has the data points reversed, XDIAG will fix the data and include a sentence in the report letting the user know. If in batch mode, it will make a note in the Batch Log. When exporting the .dyn file, it will again notify the user and give the option to save the exported file using the fixed data points.

Version 1.4.2.4 (released 23 May 2003)
New Fibercom and UPCO rod strings were added and updated.
Fixed bug where IPR Data in Canadian and Metric units caused "division by zero" error if < 5m3/D.
Fixed bug where some LCD monitors caused an "Invalid Function Call" error when using 800x600 display resolution with other than 256 color setting.
Minor corrections to wording in results report.
New Pattern Recognition data was added.

Version 1.4.2.3 (released 07 November 2002)
Fixed problem where Service Factor was rounding off to one decimal on the printed report and did not agree with screen display that supports 3 decimal places.

Version 1.4.2.2 (released 30 October 2002)
When XDIAG is run from the XSPOC program, it is no longer necessary to have a Sentinel bitlock attached for the XDIAG.
A bug was fixed so that after opening a RODDIAG file in the XDIAG program, it requires that a new report be run in order to ensure that the XDIAG analysis calculations are performed.
Several new pumping units were added.

Version 1.4.2.0 (released 2 April 2002)
The following changes were made at the request of Weatherford Artificial Lift:

• Removed Corod grade: "Corod (hollow), D" - Any older files created by selecting Corod (hollow) will default to Semi Elliptical grade D in the new versions of the software.
• Changed the tensile strength for Ultra from 150,000 psi to 140,000 psi.
• Changed grade "Corod (Semi-ellipt.), Ultra" to "Corod (Semi-el.), Endura". Did the same for "Corod (round), Ultra" (change to "Corod (round) Endura").
• Changed all Corod grade designations from "Semi-ellipt." to "Semi-el." to reduce space requirements on the screen (our suggestion).
• Change "Corod-SE" to "Corod" (In other words, by default, Corod would refer to Semi Elliptical cross section).
  Changed the tensile strength for HS41 to 130,000 psi.
• Added Round Corod 8.5R (18.5/16") which is only available in Grade D.
• We now show all Round Corods in /16" inch fractions and with a rod number (as was done for semi elliptical rods before) in the rod string information window when the user selects to rods.

For Axelson S-87, S-67, and S60 rods, we changed the calculation back to API Modified Goodman using (tensile strength)/4.0.
Fiberflex, Inc. informed us that it no longer manufactures the 1.20 inch O.D. (1.70 inch I.D.) rod. We have removed the data for the 1.20 inch rod from the library.

XDIAG 1.41 Fixlist

Version 1.4.1.5 (released 14 September 2001)
In automatic batch mode, the caption of XDIAG's status window on the
taskbar now changes to show the name of the file being processed.
Corrected the calculation of the system efficiency based on the user's
horizontal line settings.

Version 1.4.1.4 (released 23 August 2001)
Improved the way XDIAG calculates the amount of tubing movement on the downhole pump card.
Eliminated some false positives when attempting to detect a rod part.
Eliminated some false positives when attempting to detect a phase shift
in the measured surface positions.
Phase shift is no longer reported for most cases showing a traveling
valve leak.
For non-ultra-high-slip motors, improved detection of measured surface
points that are inconsistent with pumping unit kinematics.
The calculated pump friction is now reported even if conditions indicate
the value is unreliable. Please make sure you consult the Downhole section of the expert report before relying on the calculated pump friction.
In Setup, under the Expert Diagnosis tab, the minimum load shift that can
be corrected is now 1% (previously, it was 3%).
Eliminated an occasional spurious error message about the motor size
being too small.
Fixed an error in the way XDIAG attempts to compensate for tubing
movement when diagnosing a downhole pump card shape.
Fixed an error in the way XDIAG checks for an actual plunger size larger
than what was entered.
If a folder at the root of the hard drive (C:\DYNOS, for example) was
selected for automatic batch mode's XDIAG files, dynamometer files, or
spreadsheet files, XDIAG would report it as invalid.
If an invalid folder was selected for automatic batch mode's spreadsheet
files, XDIAG's error message incorrectly claimed that it was the dynamometer files folder that was invalid instead.

Version 1.4.1.2 (released 23 July 2001)
An error was corrected that caused the wrong load shift amount to be
displayed for cases requiring load span correction.

Version 1.4.1.1 (released 20 June 2001)
Severe downhole problems no longer prevent display of a diagnosis of phase-shifted positions on the measured surface dynamometer card.
If the well shows excessive friction, XDIAG now makes no attempt to diagnose a plunger size that is too small.
Updated the following pumping unit manufacturers: Ampscot Conventional
Baoji
Bukaka
CMC Conventional
Lufkin Conventional
Sentinel (new manufacturer)


Version 1.4.1.0 (released 19 June 2001)
Made several enhancements to the detection and correction of Group II wells (those with fluid inertia effects present).
Corrected problem where a poor measured surface card would cause the upstroke/downstroke indicator on the torque plot to be drawn incorrectly.
Corrected an error that occasionally caused the tubing movement to be
underreported.
Corrected an error that occasionally caused the plunger size to be
reported incorrectly.
Corrected an error that occasionally caused XDIAG to abort with a
"Subscript out of range" error message while viewing or printing the output results.
Corrected an error that could cause XDIAG to abort with an "Overflow"
error message if the surface dynamometer ard positions did not start at
zero.
Changed wording on expert report for phase shifts that are detected but
not corrected.
Added wording on expert report mentioning paraffin build-up as a possible cause for shallow friction.
Surface dynamometer card positions read from disk are now shifted to
start at zero (if they don't already), to make it easier to do history
matching with RODSTAR.
When exporting a surface dynamometer card, you now have a choice between storing the original measured card and the corrected card. XDIAG will show a list of the corrections that have been made.
Changed the file format to allow RODSTAR to have access to the corrected surface dynamometer card.
Note: This update creates files that can't be read by older versions of RODSTAR; if you have RODSTAR, you must download updates for it as well.

XDIAG 1.40 Fixlist

Version 1.4.0.4 (released 16 May 2001)
The detection of non-kinematic measured surface positions was improved.
An error was corrected that would sometimes introduce a spike into the measured surface dynamometer card when correcting non-kinematic surface positions.
An error was corrected that caused the cutoff value for correcting load span to be interpreted as a pressure (and therefore subject to change depending on the English/Canadian/metric measurement units setting) instead of as a percent.
An error was corrected that caused the dynamometer options dialog to be unavailable for some types of measured dynamometer data; the dialog is now available for all types.
An error was corrected that caused XDIAG to attempt to diagnose a phase shift on a solid line surface dynamometer card. (A solid line card does not have enough information for XDIAG to diagnose a phase shift.).
The dynamometer options dialog now disables phase shift correction options when a solid line card is selected as the source of dynamometer data.
Updated the following pumping unit manufacturers: Ampscot
Baoji
Darco USA
Lufkin Conventional - New
Lufkin Conventional - Old


Version 1.4.0.2 (released 4 May 2001)
XDIAG now performs corrections for errors in the measured surface dynamometer card positions, including phase shift and non-kinematic positions. Note that some kinds of phase shift are not corrected if there is incomplete pump fillage or gas interference, and phase shift is not reported at all if there is a severe downhole problem.
There is now a dynamometer options dialog available on the Well Information window. This dialog allows you to specify whether or not to correct non-kinematic surface positions, whether or not to correct phase shift errors (or to apply your own), and an optional load adjustment (this takes precedence over XDIAG's load shift detection, and is useful if you know your pump off controllers' measured loads are off by a fixed amount, for example). In addition, the clamp-on load cell option introduced in version 1.37 has been moved to this dialog.
Printed dynamometer cards now include indications of corrections made to surface dynamometer cards.
Full-page printed dynamometer card no longer says "Predicted."
Fixed a division-by-zero error that could occur if the first and last points of the measured surface card had the same position value.
Note: This update creates files that can't be read by older versions of RODSTAR; if you have RODSTAR, you must download updates for it as well.

XDIAG 1.38 Fixlist

Version 1.3.8.2 (released 9 Jan 2001)
Pump friction is no longer calculated if the pump fillage is less than 25%.
Corrected a problem that caused XDIAG to report some cases of a malfunctioning tubing anchor as incomplete pump fillage.
Corrected a problem causing upper ring valve pumps to be incorrectly diagnosed.
On the Motor Information input window, if the prime mover was set to NEMA D / XDIAG recommendation, and then a different motor type was selected, the program would always use the lowest torque mode, regardless of what was selected.

Version 1.3.8.1 (released 30 Nov 2000)
Windows NT and Windows 2000 user profiles are now supported. On these operating systems, program settings are stored in a folder named "THETA" within the folder named by the APPDATA environment variable (if defined) or the USERPROFILE environment variable. Note that if the program settings files are already present on the system, they will continue to be used in their current locations.
FIBERCOM fiberglass rods are now supported.

XDIAG 1.37 Fixlist

Version 1.3.7.6 (released 6 November 2000)
Added support for serial numbers greater than 32000.

Enhanced ability to correct out-of-order points on the measured
dynamometer card.

Version 1.3.7.5 (released 31 Aug 2000)
Corrected a dependence on initial conditions that would infrequently cause different results for consecutive runs of the same case
Corrected a discrepancy between the printed diagnosis and the batch mode abbreviated diagnosis

Version 1.3.7.4 (released 11 Aug 2000)
An error was corrected that allowed a calculated fluid specific gravity to affect further XDIAG runs in the same session (that is, until XDIAG was exited and restarted).
An error was corrected that caused XDIAG to forget some parts of its diagnosis when the output was saved to disk, the file was re-opened, and the results were viewed without running the diagnosis.

Version 1.3.7.3 (released 2 Aug 2000)
Enhanced detection of extreme rod-tubing friction cases.

Version 1.3.7.2 (released 21 July 2000)
Enhanced detection of high rod-tubing friction cases.
Corrected problem where XDIAG assumes that all new cases have dynamometer cards measured with clamp-on load cells.
Corrected a problem where program data files might not be located if they were stored in a folder listed on the system path rather than in the folder where XDIAG is located.
XDIAG can now read dynamometer files where the position data do not range from zero to the stroke length as they should.
When exporting a dynamometer data file, XDIAG now adds measured CBE data, stroke length, and pumping speed.

Version 1.3.7.1 (released 30 June 2000)
Added support for diagnosis of dynamometer cards acquired from clamp-on load cells. Note: This update creates files that can't be read by older versions of RODSTAR and XDIAG; if you have RODSTAR, you must download an update for it as well.
Added two new Indonesian pumping unit manufacturers: Bukaka and Ruhaak Baoji.
Reporting of excessive rod-tubing friction was enhanced.
Reporting of incorrect plunger sizes was enhanced.
Load shifts are now reported regardless of magnitude. However, if the load shift is large, warnings will be printed on the downhole, surface equipment and input data diagnoses.
The printed report now shows the number of points on the measured dynamometer card, if the card was read from a disk file.

XDIAG 1.36 Fixlist

Version 1.3.6.9 (released 21 Mar 2000)
There is a new setting in XDIAG's batch mode setup for resolving discrepancies between custom rod grades in XDIAG data files and the custom rod grades in XDIAG Setup.
XDIAG now reports a load shift if the downhole pump card has significant negative load. Since XDIAG can calculate the rod-tubing friction, most of the pump card loads should be positive.
Fixed problem where, in some cases, the fluid level would not be reported correctly.
Fixed problem where a data file containing an invalid dynamometer card would crash the program when trying to view the Well Information window.
When a batch run completes, an entry called LastBatchRunComplete is written to the [XDIAG] section of THETA.INI.
An "Out of string space" error was corrected that could occur at the end of a batch run.

Version 1.3.6.6 (released 25 Feb 2000)
When reading a RODDIAG file, XDIAG now uses the user's settings for including buoyancy effects and calculating rod-tubing friction. Before, XDIAG would always exclude buoyancy effects and calculate rod-tubing friction.
Fixed problem where, in some fluid pound cases, the fluid level would not be reported at the pump.
Fixed problem where, if the user chose to set lines on a downhole pump card when XDIAG chose not to set lines, XDIAG could initially have the lines placed off the downhole card, so they could not be moved.
XDIAG now reports an estimated fluid load on the plunger in all cases, even when it does not set horizontal lines.

Version 1.3.6.5 (released 12 Feb 2000)
Corrected misalignment of batch mode spreadsheet header columns
Updated to read files created by RODDIAG 1.9.4.3

Version 1.3.6.3 (released 5 Jan 2000)
If the option to enter rod-tubing friction is not selected in Setup, all files opened in XDIAG will now have rod-tubing friction calculated, regardless of their previous settings.

Version 1.3.6.2 (released 12 Nov 1999)
Updated pump card recognition engine
Pump friction is now calculated
Rod-tubing friction is now calculated by default
New setup option (on Expert Diagnosis tab) to allow entry of rod-tubing friction instead of calculating it
Fluid specific gravity can now be calculated

Added calculated rod string stresses to batch mode spreadsheet
Corrected problem where very large batch runs would cause out-of-string-space errors
Corrected problem where, in metric mode, rod string stresses would be displayed or printed in metric units incorrectly
When entering Setup, XDIAG now verifies the automatic batch mode directory settings

XDIAG 1.33 Fixlist

Version 1.3.3.2 (released 1 Jul 1999)

[ThetaLM]
Server=name-of-ThetaLM-server

Version 1.3.3.1 (released 16 June 1999)
Corrected situation where a very small load shift could cause no diagnosis at all to be presented.
On a case-by-case basis, buoyancy effects can be included or excluded
Inclusion/exclusion of buoyancy effects are available on the batch mode spreadsheet
Default inclusion/exclusion of buoyancy effects can be established in Setup
Changed rod stress loading for Weatherford XD and EL (Electra) steel sucker rods

Version 1.3.2.28 (released 4 Sep 1998)
In NetSentinel edition, fixed bug which caused XDWIN.DPT file to be overlooked.

Version 1.3.2.27 (released 15 Jul 1998)
Non-automated ThetaLM edition could not find license manager.

Version 1.3.2.26 (released 29 May 1998)
Added well name to the list of available batch mode spreadsheet items.
To suppress printing of the batch run log in automatic batch mode, edit the THETA.INI file to add a key named "AutoBatchPrintLog" with a value of "FALSE" to the [XDWIN] section.
