    Message from Chair

    Dear Members,

    Many of you may have noticed, but for those who have not - Here is an official introduction to the new!

    This past month APSG began rolling out the new website, updated to offer members a way to better access the information you need and better represent the organization as a whole. We believe this is a step in the right direction.

    Did you have the chance to attend this year's Esri Petroleum GIS Conference - better known in the Oil and Gas community as Esri PUG - in Houston, TX this month? We were able to catch up with APSG professionals and student members alike - such a great turn out!

    For those who missed the presentations that our members gave this year, they are available to current APSG members in the Presentations section as are photos in our Photo Gallery online.

    APSG Central Chapter News

    Dear Members,

    I wanted to share with you the recent activities within our Chapter.

    The Spring meeting was a resounding success. In fact it was our best meeting in terms of attendees. The presentations were very well received and the feedback was also very positive . For those of you who missed the meeting the theme of our meeting was "Advances in Geo Spatial Technologies" and we had presentations on UAV, LIDAR and other new technologies. We had several excellent speakers. I have had several attendees calling me and wanting to include the same topics for our next meeting as they felt the rules governing the UAV's are rapidly changing and they need to be aware of the new rules. We will consider this request along with other suggested topics for our fall meeting which is scheduled for October 29th, 2015. The location and the theme has not been decided but will be announced soon.

    Back to the Spring meeting and I want to thank all the presenters, volunteers, attendees and sponsors who made the meeting a great success.

    I would also like to inform you that the APSG's first student chapter at Texas A and M university is now officially recognized and we are planning activities with them. If any one of you is interested, please contact us.

    I also want to update you with the personnel changes in the Central Chapter. Robert Edwards, our treasurer, Erin Medina our Website chair and Samantha Murray our education chair have decided to step down due to various reasons. At the last STAC Meeting it was decided that Stephan Kieval will be the interim website chair, Kelly Fournier will be the interim treasurer and Greg Pilgrim will be interim membership chair. Please join me in welcoming these folks to our APSG team. Also please join me in thanking Samantha, Robert and Erin for job well done.

    Stay tuned for details on the Fall meeting

    IOGP  Releases Version 1.1 of its P1 and P2 Geophysical Position Data Exchange Format

    Dear Members & Guests,

    The International Association of Oil and Gas Producers (IOGP) has released version  1.1 of its P1 and P2 geophysical position data exchange formats.  Originally released in 2012 to replace the UKOOA P1/90 and P2/94 formats, the revised versions incorporate industry feedback from the first release and provide greater flexibility – without changing the fundamental format structure. For example, the format now enables the recording of land and OBC formats and additional peripheral sensor or QC data. 

    The OGP P1/11 v1.1, OGP P2/11 v1.1 formats are available at: and (also at

    The formats incorporate learnings from the first two years of implementation and include enhancements requested by the industry, such as: handling channel grouping; ‘virtual’ position objects such as mid-points; global pre-plot attributes; event-based attributes; receiver and source relation records
    IOGP is revising the original user guide. It is expected to be published during Q3  2015.

    In Remembrance of Jerry Hubbard       January 9, 2015  

    On behalf of the APSG Committee we would like to inform you of the passing of our Dear Friend and Colleague Jerry Hubbard

    Dear APSG Family,

    Jerry Hubbard, President of Energistics, who was a great supporter of our efforts and instrumental in getting OMG associated with the work of the Standards Leadership Council, which he founded and co-chaired, suddenly died at home on January 1, 2015. He had been recovering from cancer surgery and some as-yet unspecified complication is suspected -- although no details are available.

    Those who knew him will remember his dedication, experience, intelligence, leadership and humor. He did great things to organize the O&G standards community and create a vision for convergent efforts. Please have a thought for his family at this difficult time.

    Jerry was a key contact for us, and a person who could enable our moving our message out amongst standards organizations – Jerry’s leading the Standards Leadership Council has taken standards correlation and coordination to a new level since its inception… "
