New Features in 2015.1 (Build 220.127.116.11, March 2015)
- Neuman-Witherspoon Pumping Test Analysis: A pumping test solution useful for determining hydraulic properties of leaky confined aquifers. Unlike other leaky methods, Neuman and Witherspoon accounts for drawdown in the unpumped aquifer.
- Dagan Slug Test Analysis: A robust slug test solution useful for determining hydraulic conductivity of unconfined aquifers when the well is screened across the water table.
- Well Efficiency Plots: Easily calculate well efficiency and the optimal discharge rate.
- Variable Discharge Diagnostic Plots: Easily identify model assumptions and select the most appropriate solution for variable discharge pumping test data.
- Faster Importing of Datalogger Data: Simply drag and drop your datalogger files directly onto AquiferTest for instant data importing, using DropZone.
- Updated look and feel, with new icons, display
- Automated softawre licensing system
Lugeon Testing Method
- The Lugeon test (or Packer Test) is an in-situ testing method widely used to estimate the average hydraulic conductivity of rock formations.
- The Lugeon test is a constant rate injection test carried out in a portion of a borehole isolated by inflated packers. Water is injected into the isolated portion of the borehole using a slotted pipe. Water is injected at specific pressure “steps” and the resulting pressure is recorded when the flow has reached a quasi-steady state condition. A pressure transducer is also located in that portion of the borehole to measure the pressure with a help of reading station on the surface.
- The results provide information about hydraulic conductivity of the rock mass including the rock matrix and the discontinuities.
- Greater control over the parameter estimations: define the range of values that are relevant to the analysis and have the automatic fit honor these parameter ranges.
- Display calculated values (T, S, etc) as numeric format (currently it always displays as scientific format). Ideal for reports. With option to change the # significant digits for these parameters.
- Removed the upper limit for S (previously was 0.5); this was causing analysis limitations when doing a Cooper-Jacob analysis, if you wanted to estimate T from the pumping well.
- When entering water levels, display the well elevation and TOC values.
- Well geometry grid, added more options for defining the data values, including copy/paste from clipboard
- Add copy and paste for most of the input fields for Pumping Test/Slug Test info (Project Info, Name, Client, Location, etc. and in the Trend/Barometric corrections grid
- More feedback after importing a data logger file: display the number of filtered records or invalid rows
- Improved printing/reporting for Pumping and Slug Tests – Send all reports, consolidated into a single PDF file
- Condense multiple slug tests into a single PDF report
- Display water level data in the reports as water level (amsl).
- Added a Start page with useful links to recent projects, example projects, and on-line support and resources
- Added an option to zoom in/zoom out in the time vs. water levels plot
- Added Apply buttons to most dialogs
- Added an option to set preference to go directly to the traditional dimensionless analysis view
- Allow option to cancel an automatic fit if it takes too long, adjust parameters, and re-start
- Added option to duplicate an existing analysis
- Added support for .XLSX files importing
- Added option for data filtering of water levels using logarithmic time scale
- More flexibility for editing titles on the Analysis reports
- Added option for importing georeferenced TIFF images in the Site Plan view
Pumping and Slug Test Analysis Methods
- Agarwal (1970) – A pumping test solution for wells dominated by wellbore storage and skin effects
- Butler High-K Slug Test (2003) – A slug test solution for wells in formations of high hydraulic activity in confined or unconfined aquifers.
- Neuman analysis now has an option to use table interpolation which provides a much faster solution
- Clonts and Ramey – A pumping test solution for horizontal wells
- Scatter plots showing the quality of fit of observed and calculated drawdown can now be displayed and included in analysis reports.
- A derivative analysis tool was added to the Analysis menu to aid in diagnosing aquifer conditions and type curve matching
- Type curves can be automatically displayed in dimensionless view for applicable analysis methods (Hantush, Neuman).
- Curves can now be manually fitted to the data using your mouse or keyboard.
Updating Old AquiferTest Projects
AquiferTest is backwards compatible, and is able to open any projects from v.4.X. If you are opening a project from 4.X, create a copy of the project file (.HYT) before opening in the new version. Once a project has been converted to a new format of AquiferTest, it can no longer be opened in the previous version.
* Waterloo Hydrogeologic is not responsible for any direct or indirect damages caused to projects during conversion. It is strongly recommended that you create a secure, independent back up of projects before converting.
Addressed in v.2012.1 (December 2012)
- Fit line for Cooper-Jacob I Analysis moves when switching between analyses; this due to high value for S
- Error when you try to add create/adjust type curves for Moench
- Problem with the correct reference datum not selected when using data logger wizard
Addressed in v.2011.1 (June 2012)
- Fixed endless loop with new project, when clicking on the New button on the toolbar
- Bouwer-Rice Coefficients added to the Analysis Statistics report, including display of r(w), when selected.
- Updated example projects to latest build
Added in v.2011.1
- Cooper Jacob straight line fit sometimes shifts when changing to the report tab or after printing.
- Locked parameters move when automatic fit is applied in a slug test
Added in v.18.104.22.168 (May 2010)
- An installed printer is no longer required to run AquiferTest
- The “Division By Zero” error message no longer shows when the Analyses Report is selected in the Report tab
- Graph templates designed in previous versions of AquiferTest are not recognized. Graphs settings should be re-designed and saved in the new version.
- When doing an automatic fit with the Neuman analysis, the processing times are slow for certain ranges of the Beta value. Try doing a manual fit first, then attempt the automatic fit. Another option is to enable the Neuman table interpolation setting in the AquiferTest general settings. This option provides a much faster solution, with slighly less accurate results.
- When using existing graph template settings with any of the following methods, the analysis plot page becomes blank or distorted: Cooper Jacob (all), Theis recovery, Slug Tests and Specific capacity analysis.
- Delete these graph template settings using Edit / Delete Object / Graph template, and re-create the templates.
- After performing a remote-update with a network dongle on a 64-bit machine, the network licence will turn into a local license.
This is a compatibility issue with 64-bit computers. For network licenses only, be sure to run remote-updates using a 32-bit computer
- Attempting to open a project (File > Open) that does not exist will result in multiple error messages and may cause the application to crash. Please ensure that the project name you type in the File > Open dialog already exists in the specified path before clicking the Open button.
- If you are installing an AquiferTest Standard license after having the Trial version installed, you will need to uninstall the Trial version then delete the registry key “HKEY_LOCAL_MACHINESOFTWARESchlumberger Water ServicesAquiferTest Pro450REGISTRATION”. Then reinstall with your Standard Serial number and request a license. In addition, you will have access to the Trial (Pro) features for the duration of your trial period (30 days); after this time, your software will revert to the Standard license.
