PetrisWINDS Recall 5.2

Petris is pleased to announce PetrisWINDS Recall 5.2, the new release of the PetrisWINDS Recall borehole database and processing suite.

PetrisWINDS Recall 5.2 is based on the ground-breaking PetrisWINDS Recall 5 and includes numerous enhancements and new modules. It was released at the end of 2007 on three platforms - Windows, Linux and Solaris.

New Applications

New SUPERVIEW applications include the Image Loader Wizard. This wizard greatly simplifies the process of identifying, loading and pre-processing borehole image logs. It handles formats and tools from all the major service companies. The wizard guides the user step by step, identifying the tool, loading the raw data, applying specific pre-processing algorithms and generating intermediate and final QC plots.

The Checkout Module provides a mechanism to control access to data being modified by more than one person. The module is typically launched from the Recall browser against a table in a selected database. It allows that table to be locked for the exclusive use of a particular user, and also allows the table to be temporarily copied (“checked out”) to another location (perhaps a laptop). The module can display the status of any table and indicate if the table has been checked-out or locked and by whom

Core Data Developments

Core data poses special problems in the storage and analysis of well bore data. There are many different types of measurement with many different processing and visualization requirements. The most important requirement is that the data be tightly integrated with the rest of the well bore information. The latest Recall developments cater for all current types of core data.

Core Data Base Features

 Support for all known core data types and measurements
 Integrated with all other depth or time based borehole data
 Fully interactive LOGSCAPE visualization and interpretation
 Specialized loading and reporting modules
 Data organization enabling processing by all standard Recall tools
 Handling of multiple depth references (driller’s, logger’s, TVD, TVT, TST, multiple datums) and full support for deviated, horizontal & upturning wells

LOGSCAPE Developments

Plotting

The control of plotting and the saving of plot files from LOGSCAPE is now simple and intuitive, as is the pasting of LOGSCAPE plots into MS products. Windows-style dialogues control print preview & manipulation options, while output formats feature JPEG, Bitmap & Encapsulated Postscript as well as CGM. The addition of more flexible headers, curve backup options, curve-based shading and image log plotting (see below) enable LOGSCAPE to be used as a versatile plot tool for all single-well display needs.

LOGSCAPE ‘Process’ track

The use of formulae in LOGSCAPE has been extended to include arbitrarily complex Transcript jobs and other modules such as ‘Bad Hole’. A saved Job Edit/Review Transcript job (with required inputs & outputs identified) is imported as a LOGSCAPE ‘process’, and the user is prompted to ‘hook up’ the I/O handles to the LOGSCAPE workflow. Such external processes can be run either manually on request, or automatically as part of a complete processing template.

Images & Posted Dips in LOGSCAPE

The process track feature (above) can be used to compose image log views with posted dips, and plot them in LOGSCAPE. Input image logs are chosen from Recall while dip logs can be either from Recall or (edited) dips in LOGSCAPE.

Image Filter Developments

The image Filter module includes a number of new ‘texture’ property filters and creates output curves summarizing these properties depth by depth. Properties include ‘frequency of crossing threshold’, where threshold is either user-specified or derived as a percentile of the local image value distribution. Results of texture filters as images can be previewed in Image Display or plotted in Spatial.

Full implementation of tabular database security and role based User access

The developments initiated in Recall 5.1 for tabular security and User Groups have been completed in Recall 5.2. The tabular security option allows complete access control for any data set in a Recall database. The implementation of User Groups will significantly simplify the administration of User access to Recall Corporate Databases by allowing individual Users to be assigned role based access to data in the database

Other improvements to the system include:

 Many improvements to the handling of image tools and formats, including OMRI, CMI, XRMI, FMI, STAR and Geoframe
 Accelerometer Correction is now more robust & accurate, especially for Halliburton & Weatherford tools.
 Major enhancements to the Bulk Data Editing module
 Further improvements to the File Level Security of Recall databases.
 An Undelete facility makes it possible to view deleted tables from the Recall browser and select them for un-deletion..
 A WITSML output module
 Handling of LAS 3 input files

PetrisWINDS Recall5 was a great step forwards for Recall and the first version running on Windows. Now Recall 5.2 has built on that advantage with a host of developments and enhancements, both improving usability and adding new functionality.
