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.

Balancing a Gas Lift System: Part I
Date: 11/29/2017

When a producing well’s output approaches an economically impractical level, producers often turn to more specialized operations to extend the well’s life.  One of the more common techniques is a gas lift system in which natural gas is injected back into the well.  The gas is typically measured prior to injection and the combined production and injection gas stream (referred to as return gas) is subsequently measured.  The "formation production" is generally determined by calculating the difference between the return gas and injection gas volumes.  The sales gas is then measured at the point of custody transfer and any fuel consumption used for compression or by other equipment is assessed.  The total formation production volume less the sales gas and consumed fuel is the basis for performing system balances.
However, there is a common reporting problem in balancing a gas lift system with this approach.  Even in the absence of other measurement problems, an imbalance is often an unusually large percentage of the formation production volume which is determined by taking the difference between two relatively large numbers: the injection volume and the return volume.  When this occurs, stating the imbalance as a percentage of formation production is significantly less useful, as demonstrated by the following:
In this case history summary, the uncertainty compared to the calculated formation production is 38%; as a percentage of the total measured volume, however, the uncertainty is only 2%.
The issue of expressing the imbalance as a percentage of the formation production cannot be resolved since this is inherent in the formation production calculation method itself.  The uncertainty percentage is better understood when expressed in terms of the total measured volume.  Otherwise, normal variances in formation production uncertainty may mask actual measurement or operational issues.
Measurement problems that are commonly experienced in gas lift systems will be covered in Part II of this Statement of the Month topic in January 2018.  In the meantime, if you believe that a measurement problem exists in your system, be sure to consult with your measurement experts, whether in-house or third-party, for a thorough analysis and final resolution.
