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 BirdDogSystemSupport@birddog.coastalflow.com

Balancing a Gas Lift System: Part II
Date: 1/30/2018

As covered in Part I of "Balancing a Gas Lift System" (November 2017), it’s recommended that imbalances be expressed as a percentage of total measurement to effectively monitor for measurement and operational problems.  Part II of this topic presents three of the most common measurement problems that can cause excessive "Lost and Un-Accounted For" (LUAF) quantities in gas lift systems.  When these occur, measurement error is often severe.
 
Compressor generated pulsation can be one of the most difficult measurement problems to identify.  The most effective way to avoid this problem is to install meters at an appropriate distance from the compressors, but this may not always be an option…especially in a gas lift system.  Other measures to reduce or even eliminate pulsation include:
  • Installing a smaller orifice plate to increase the differential pressure.
  • Installing pulsation dampeners between the source and the meter.
  • Shortening the gauge lines or using direct mount block manifolds. 
Meters affected by pulsation will usually overstate the volume, although understatement is possible, and the impact of pulsation-induced errors can easily exceed 50% of the volume.
 
Free liquids can also cause measurement problems in a gas lift system.  Among the good practices that can mitigate measurement errors from free liquids at the meter are:
  • Installing meter fittings with vertical taps.
  • Installing gauge lines with sufficient slope.
  • Installing additional liquid separation, as necessary. 
Errors related to free liquids can overstate or understate volumes and can range from insignificant to severe depending upon how much liquid is present and where it’s located at the meter.
 
Unrepresentative gas analyses can affect measurement accuracy in a gas lift system.  A single analysis applied to both injection and return meters may introduce errors as their gas qualities can vary considerably.  Accurate gas sampling can be a challenge, in part, due to contamination from free liquids.  However, most streams can be accurately sampled when using the proper equipment and procedures, as discussed in GPA Standard 2166.
 
While more than 50 common sources of orifice measurement errors have been expressly identified, compressor generated pulsation, free liquids, and unrepresentative gas analyses are very common in gas lift systems.  Whenever possible, proactive measures should be taken at start-up to minimize or eliminate these potential sources of error.  And since these problems can be difficult to identify and resolve, you should consult with your measurement experts, whether in-house or third-party, for assistance.
 
"Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth."
~ Arthur Conan Doyle, British author and physician
