As a geoscience student, I was introduced to the professional societies by an alumnus of my alma mater, Oklahoma State University. Herb Davis was very active in the Oklahoma City Geological Society and frequently sponsored students to attend the luncheons and technical talks. He emphasized the importance of building networks within your geoscience community outside of your current employer, alumni, and circle of friends. He also led by example the concept of paying it forward to the next generation. This was a valuable lesson.
In this rapidly changing work environment for geoscientists, the need to maintain these networks has never been greater. With work-from-home/flexible schedules, constant mergers and acquisitions, and new business lines that will require geoscience skills, the need to have a viable society that can provide networking opportunities, mentoring, and technical training has never been greater.
Many of the geoscience societies have been under immense financial pressure over the last 10 years as corporate sponsorships have waned and memberships have declined. HGS has been working very hard over the past few years to balance financial health with continuing to offer programs, training, and networking opportunities that benefit the members and encourage new membership. I am running for president-elect because I want to continue to be part of that positive direction and see HGS thrive as a professional society.

Ever since I joined the HGS, I have enjoyed the benefits of education, networking, and friendship. Currently, I am working with the GCAGS as Treasurer. For about 7 years, I spent much of my time working on the exhibits committee, organizing the setup and transportation of the HGS booth for various conventions throughout the year. When I served as HGS Secretary, it afforded me the opportunity to learn more about the many functions of the HGS. I was also exposed to the duties as the HGS Treasurer-elect and Treasurer, where I witnessed the society’s dedication to the various efforts through the annual budget. I was then given the opportunity to serve as the HGS Vice President during the COVID-19 pandemic, where I was able to schedule all our monthly technical talks digitally for the first time. Currently, I am chairing the HGS New Energies Group, which meets regularly to discuss carbon sequestration, lithium extraction, geothermal, and other new areas where geoscientists play a key role in supporting projects. It has been a pleasure meeting many people along the way, and I am thankful for the opportunities the HGS has provided me while serving as Chairman, Secretary, Treasurer, and Vice President. It would be my great pleasure to serve in the capacity of HGS President-Elect.

NeoGeos Committee Chair – 04/2022 – 05/2024
I am honored to accept the nomination for the HGS Secretary. I have spent the past few years becoming increasingly involved in the HGS organization, recently serving as the NeoGeo Committee Chair from 2022 through 2024. As the NeoGeo Committee Chair, I hosted monthly Happy Hours and Trivia events targeted at increasing member involvement among early-career geologists. While serving as chair, the NeoGeos committee was revitalized, and once again hosts regular monthly events after languishing during COVID. Under my leadership, we increased sponsorship outreach and boosted event turnout and revenue for the society. I have since passed the torch to a new group of NeoGeos Chairs, and they have continued the amazing growth in turnout and sponsorship. In addition to serving as NeoGeos chair, I have volunteered at numerous events, such as the education outreach in elementary schools program targeted at teaching local elementary students about rocks and fossils, serving as a poster judge for the annual Sheriff Lecture event, and serving as a judge at the 2023 Science and Engineering Fair of Houston on behalf of HGS. I’m excited for the opportunity to continue serving this organization in an increased capacity. By serving as Secretary, I hope to set an example among other early-career geologists, encouraging them to become more involved with their local geologic society. I hope that my potential presence in the organization can bring some fresh perspectives and ideas to the organization that will benefit society as we continue to adapt to an ever-changing world.
I am honored to have been asked to run for HGS Treasurer-Elect, as I would love to continue giving back to HGS. As the current treasurer of the HGS Undergraduate Fund, I feel that this is the right office for me to accomplish this goal. I have been a member of the HGS for 22 years, the same amount of time I have resided in Houston and worked for Shell. Through this organization, I have met many amazing individuals, many who have become friends and have seen the good that the HGS has done and can continue to do for not only students, but all who are students of the Earth. I am an enthusiastic, high-energy individual with excellent organizational skills that have served me well in various capacities, including as treasurer of the HGS Undergraduate Student Fund, my daughter’s Girl Scout Troop, and the social committee in my neighborhood. I look forward to being a future HGS officer and helping to grow this great organization’s finances so that we can continue to support continuing education, networking, and outreach to students, to cultivate our next generation of HGS leaders.
Previous HGS Offices or Committees:
I am honored and excited to stand for the role of HGS Treasurer-Elect. Having previously served as Director and Vice-President earlier in my career, I am eager to continue giving back to this remarkable organization that has been instrumental in shaping my professional journey. After spending time working outside of Houston, this opportunity to once again serve HGS feels like coming full circle.
The role of Treasurer-Elect aligns closely with my experience, particularly my tenure at Shell, where I honed my skills in leadership, decision-making, and had P&L accountability for the Appalachia asset. I am an organized, high-energy individual with a passion to lead and drive meaningful impact”. Throughout my career, I have been dedicated to supporting the HGS and AAPG communities by contributing my time, talent, and resources to foster professional growth, collaboration, and improve membership value.
Having recently taken early retirement from Shell, I am now pursuing a variety of interests, including consulting, coaching, and cherishing time with my high-school twins before they embark on their college journeys. This new chapter has reignited my enthusiasm to serve HGS with fresh energy and focus.
As Treasurer-Elect, I aim to strengthen HGS’s financial foundation to ensure we continue offering outstanding technical content, continuing education, scholarships, and vibrant social networking opportunities for all members—new and longstanding. HGS has provided me with the foundation for a fulfilling and successful career, and it would be my great privilege to give back to our proud geological society and community.

"The geology profession seems to have taken a back seat, at least that is the perception in the oil&gas capital of the world! It is true to some extent, Jobs are slowly transforming as we speak. Oil&gas companies have transformed into energy companies, increasing their renewables share in portfolios. However, we at the Houston Geological Society promote geoscience at large, manage precious natural and mineral resources, and the environment, educate about responsible energy usage, conservation, and transformation, manage and store carbon, educate about managing natural resources and geohazards, and just enjoy the pure joy of sharing the Earth's history! Geoscience has never changed. We continue to do what we are good at. Let us be good scientists first. I think, as the 100-year-old organization that we are, we have a job to do. Geoscience has become more relevant in the new energy economy and the climate dialogue, and has a larger influence on human society. As one of the Directors on the Executive Board. I would do just that, promote the Geoscience education and profession".
I am honored to stand for the position of Director at the HGS. I will bring my 35 years of business experience to the Executive Board and strive to make the HGS economically profitable, scientifically relevant for all HGS members … and fun!
The critical strength I can bring to the HGS is a strong understanding of the financial challenges we face as a professional society, and HGS’s need to continue to grow its outreach and appeal to all geoscientists.
My executive experience ranges from small independents to "big oil companies" to investment banking. I have held the positions of Exploration Manager at Marathon Oil Company, Exploration Vice President at Roxanna Oil Company (a local Houston independent oil-and-gas company founded by the late, great Maryln Downey), and Senior Vice President and Chief Geologist at Goldman Sachs here in Houston.
I am an active member of HGS. I actively participated in the Continuing Education Committee by teaching HGS classes and doing the logistical minutiae of soliciting new teachers for HGS classes, finding event venues, and even picking up the bagels and coffee for the class's morning breakfast.
I have received the HGS President’s Award and the HGS Chairman’s Award for my service to HGS. I have also received the dedicated Service Award from the AAPG and the West Texas Geological Society.
I currently run a consulting company. I am an angel investor in a major domestic start-up where we aspire to drill some very important wildcat wells in the Gulf Coast. I like to look at deals and participate in oil wells. I also generate my own prospects for fun and, rarely, for profit.
THANK YOU!
I am interested in serving as a Director for the Houston Geological Society because I have such high regard for this group and its members. In my view, this society is the best of all the groups affiliated with the American Association of Petroleum Geologists. The Houston Geological Society has provided opportunities for knowledge sharing and networking for decades. It seems the best part of being a geoscientist is getting to collaborate with colleagues and having fun when we get together to share ideas. I would like to do my part in making sure this society remains financially strong and stays focused on its core objectives: "1) To stimulate interest and promote advancement in geology for the Houston area. 2) To disseminate and facilitate discussion of geological information, build relationships among geologists in the area, and aid and encourage academic training in the science of geology."
Born in Hondo, Texas, Catherine Strong is a graduate of Texas A&M, where she earned two degrees, Bachelor of Science in geology and Master of Science in geology, before joining the oil and gas industry as a Petroleum Geologist in 1982. Ms. Strong’s years in upstream oil and gas have resulted in technically diverse and geographically broad expertise in domestic as well as, foreign areas. Most successful endeavors have been in Gulf of Mexico exploration, Gulf Coast exploration, production, and in technology development for Unconventional Resources. Ms. Strong also has significant experience in obtaining partner companies and in screening prospects and production opportunities.
Strong joined Red Willow Production Co., an affiliate of the Southern Ute Indian Tribe, in 2015 as the lead geologist in the Houston, Texas, office responsible for prospect, lease sale, and project development decisions in the deep-water Gulf of Mexico. In 2015, Ms. Strong accepted early retirement from ConocoPhillips after sixteen years with the company. During her tenure at ConocoPhillips in Houston, Texas, she served in director, technical advisor, and team-lead capacities for deep-water Gulf of Mexico exploration and in technology development for tight-gas-sand and shale unconventional resource plays. Before ConocoPhillips, Ms. Strong was a principal geologist with Vastar Resources (an affiliate of ARCO) for three years, where she worked on exploration in the deep-water and deep-shelf areas of the Gulf of Mexico.
Strong began her oil and gas career with the Hunt Family in Dallas, Texas, where she handled geological and team-lead duties for fourteen years at Petro-Hunt and Placid Oil, honing her skills in the Gulf of Mexico, the Gulf Coast, offshore California, and international assignments. Ms. Strong is a Licensed Professional Geoscientist in the State of Texas. She is a member of the American Association of Petroleum Geologists, where she is a House of Delegates representative. Strong has been active with Texas A&M’s Department of Geology, Geophysics Advisory Committee, since its inception in 2006, and she is currently serving as the Chair of this Advisory Council.
It was not until 2015, while working downtown for EP Energy, that I began being a truly active member of HGS by attending luncheon meetings and continuing education courses. Between HGS and the Society of Independent Professional Earth Scientists (SIPES) meetings (I mention SIPES because there is a substantial overlap between HGS and SIPES members), I have never met an assemblage of more friendly and supportive fellow geologists. The people are what kept me coming back.
As a result, I jumped at the opportunity to be a co-chair of the Social Media committee in the fall of 2017. At the time, it was my intention to help the committee for a few months while in their time of need. It is now 2024, and I am still thriving on social media. Additionally, I also volunteer on the Continuing Education committee. All in all, I never knew how rewarding it was to volunteer. I find giving back to HGS incredibly rewarding because of the caliber of its members. I have met some truly interesting people and formed strong friendships since joining HGS. That is what I enjoy the most… the people. At a job and in life, the people make it or break it for me.
