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

How much C6+ is too much?
Date: 6/29/2016

Although there is no absolute limit for the concentration of C6+ in natural gas, when it is present in significant concentrations it will generally range from the sum of iso-pentane and normal-pentane to approximately double that sum.  However, there are some important factors to consider when identifying the C6+ concentration and avoiding a falsely high reading. 
  • What is the geographic location where the natural gas stream originated?
Natural gas wells from different regions will have varying amounts of hydrocarbon liquids.  For instance, production from shale formations tends to contain more natural gas liquids (NGLs) than that from more traditional sources.  The formation as well as the drilling/production methods should be taken into account when determining the C6+ content.
  • What is the flowing temperature and pressure of the natural gas stream that was sampled?
Natural gas streams flowing at low pressures with average-to-high temperatures can show increased concentrations of NGLs.  Conversely, at high pressures and low temperatures the C6+ concentration is generally lower due to the heavier hydrocarbons condensing as liquids.
  • Was the sample obtained properly?
Poorly obtained samples can lead to liquids condensing on the sample cylinder walls.  At times, depending upon sampling conditions and gas characteristics, sample cylinders must be heated before pulling a sample to prevent condensation.
  • Was the sample cylinder cleaned properly before collection?
Improperly cleaned sample cylinders may contain residue from previous samples, thereby potentially contaminating the new sample and invalidating analytical results.
  • Does the gas chromatograph used to analyze samples have a linear response over the entire concentration range being analyzed?
Improperly calibrated gas chromatographs that are linear for each component over the expected concentration ranges.
 
These pragmatic considerations, in combination with a database for comparing the historical concentrations of C6+ in any given natural gas stream over time, should help analysts determine if a sample is representative or if it should be carefully re-sampled for more accurate results.  For more information on C6+ determinations and the considerations summarized above, contact an experienced commercial laboratory that specializes in natural gas and NGL analysis.
