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

Difficult Problems Simple Solutions
Date: 10/25/2016

One of the most common sources of orifice measurement errors in the natural gas industry is compressor-generated pulsation.  This elusive and often overlooked problem can overstate or understate measured volumes and can result in errors of greater than 50%.  Operationally, the best approach is using just plain common sense: don’t install your meter in close proximity to a compressor.  But relocating an existing meter may not be an option.
Successful measures that can markedly reduce or even eliminate the effects of pulsation include installing diffusion plates, pulsation dampeners, or other flow restrictions, thereby causing a drop in line pressure.  Among the less intrusive, more cost-effective solutions are re-installing the meter with "direct mount" gauge lines, shortening the existing gauge lines, or increasing the differential pressure (DP) by installing a smaller orifice plate.
By way of example, a midstream operator was experiencing significant system imbalances and subsequently contracted for a study which targeted locations near compressors as areas of potential concern.  Tests were performed to detect and quantify existing pulsation errors using high-speed transmitters coupled with frequency-analyzing software.  At one location in particular, production from multiple wells flowed into the suction of a single compressor, with the discharge gas measured approximately 100 feet downstream.  Testing indicated severe pulsation at the meter station which resulted in overstating the volumes.  By installing a smaller orifice plate and increasing the DP to above fifty-percent of the available range (about 140" out of 250"), the measured flow rate decreased by 46%.  This resulting flow rate closely agreed with the measured totals of the source wells less the calculated fuel gas volume.  [Click here to view the flow graph before and after the plate change.]
In this example case, a simple orifice plate change helped to reduce measurement error and the unacceptable system "Lost and Un-Accounted For" (LUAF) volumes.  Although other situations may require costlier measures for resolution, trying the simpler (and generally less expensive) options first is often the preferred approach.  If you are experiencing unacceptable differences in your hydrocarbon balances, be sure to consult with your organization’s measurement experts, whether in-house or contract servicer, for help in reconciling these differences.
