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.

Custody Transfer Measurement of NGLs
Date: 4/30/2013

Custody Transfer Measurement of NGLs

Natural gas and crude oil are generally measured on a volumetric basis, which is readily accepted by production, processing, and transportation operators.  However, the measurement of natural gas liquids (NGLs) is much more challenging due to the almost constant variation in component content, density, and compressibility.  The mixing of multiple NGL components does not necessarily result in a combined volume which is the sum of the individual components…due to compressibility and physical characteristics.  Therefore, for custody transfer accuracy, the primary measurement of NGLs should be in a mass quantity (pounds) and then, if necessary, converted to a volumetric quantity, with proper sampling and analysis per API or GPA standards.

Historically, mass measurement has been achieved by combining the results of a volumetric (e.g., turbine) meter and density meter at flowing conditions.  Combing the two measurements produces an inferred mass quantity (i.e., volume x density = mass).  Various types of technologies have been used for both the volume and density measurement.  Fairly recent technological developments have brought the Coriolis meter to our industry.  A Coriolis flow meter measures mass flow directly at flowing conditions; it is not the result of two separate instruments and measurements.  Either method of mass measurement, whether direct or inferred, has its advantages based on its suitability for the various operational environments encountered in NGL measurement.  As always, it’s highly recommended that you consult with a hydrocarbon measurement specialist to select the equipment and processes that will provide optimal measurement accuracy.
