BirdDog Version 4.0

BirdDog™ Information Systems is pleased to announce the release of Version 4.0 of Remote Data Retrieval. This newest system, to which you automatically have access when you log into our host site, provides enhanced features that are certain to make you even more productive... such as a more streamlined and intuitive user interface, the ability for end-users to perform ad hoc changes to alarm settings, and layered administration. With layered administration, end-user organizations can assign BirdDog client administrators who, in turn, will be able to add/delete other enterprise users, set each user's rights (from read-only through full editing, including use of Demand Polling), reset user passwords, add/delete Morning Report recipients, and much more.

In addition to the BirdDog Remote Data Retrieval system functional enhancements, we've also deployed new security provisions to further complement our previously implemented use of an HTTPS website to provide full SSL encryption of your sensitive and proprietary information. These enhancements include the use of unique email addresses as User IDs, as well as stronger Password requirements with history restrictions and forced routine changes. As before, with just a single account User ID and Password, your log-in will provide direct access to all BirdDog SaaS (Software-as-a-Service) systems to which you have end-user rights. And as you add or remove systems from your user profile, the single sign-on process will automatically recognize those changes.

BirdDog Security Policy Change Alert

Security Policy Change Alert - For the enhanced security of BirdDog™ Information Systems users, effective November 11, 2013, User IDs will be unique email addresses and account password requirements will be strengthened. New passwords will need to be at least 8 characters in length and contain at least one each of the following characters: uppercase alphabetical; lowercase alphabetical; numeric; and “special” (such as @, &, _, #, etc.). At the appropriate time, you will be prompted during your BirdDog log-in to click on a webpage link that will provide more details and guide you through your password change process.

BirdDog System Support

  • Log-in and system support, including password resets, are available to customers on a 24x7 basis by calling, toll-free, 800-231-9741. During business hours (8:00 a.m. until 5:00 p.m. Central Time, Monday through Friday), your call will be directed to the appropriate technical support or customer service team member.

  • During non-business hours, callers will be presented with a main menu which includes an option to reach system support and, if appropriate, to mark your message as “urgent” for an expedited response. Non-urgent support calls will be returned the next business day.

  • System support requests or questions may also be submitted via e-mail to

Slower Chart Rotation
Date: 5/31/2016

Can chart recorders be converted to a slower rotation without losing measurement accuracy?  In orifice flow measurement, that question has been asked for decades since a slower clock rotation saves money by reducing the number of charts per month, thereby saving labor to change the charts, decreasing chart postage or delivery expenses, and reducing the work required to process the charts to produce a volume statement.  If measurement accuracy will not be compromised by doing so, it may be economically prudent to make such changes, especially in light of the current oil & gas market.
Before making a change to slower chart rotation, how can you determine if measurement accuracy will be affected?  Starting from a 7-day or 8-day rotation, note the current chart pattern.  [A pattern is a temporary flow rate change that routinely occurs more than one or two times per week.]  If there is no clearly discernable pattern that has a period of less than four hours, then you can confidently change these to a 31-day rotation.  If there is an identifiable pattern of between four hours and two hours, you can change to a 16-day rotation.
However, if the pattern is between two hours and one hour, you do not want to change the rotation unless the resulting band would be interpreted at the same root-average (consult with your measurement expert for this determination).  If the pattern is already less than one hour in duration (and not really discernable), the effect on measurement has already been accounted for and the charts may be converted to a 31-day rotation.
Electronic gas measurement generally has a flow resolution of one second and always provides greater resolution than chart-based measurement.  Chart patterns that primarily consist of flow in discrete, closed (i.e., no daylight between up and down on the differential) "kicks" should not be converted.  They already have high measurement uncertainty and consideration should be given to converting meters with this type of flow pattern to electronic measurement to properly quantify the magnitude and duration of the flowing periods.
Example charts that demonstrate the patterns described above are available by clicking here.
