What Houston Geological Society does
Mission
The Houston Geological Society is a professional society for petroleum, energy and environmental geoscientists. The Houston Geological Society supports continuing education, networking, outreach to students, student scholarships and young professional activities.
As stated on its FY2025 Form 990.
Programs
The objectives of the Houston Geological Society are: to stimulate interest and promote advancement in geology for the houston area; to disseminate and facilitate discussion of geological information relationships among geologists in the area; and to aid and encourage academic training in the science of geology.the society strives to achieve these goals through regularly scheduled technical meetings, publication of a monthly bulletin, a continuing education program, field trips, the publication of timely books, and two student scholarship funds.
Through its publication efforts, the society has rendered a service to its members, the geological profession, and occasionally to the entire community with books of general interest. The publication, "houston area environmental geology: surface faulting, ground subsidence, hazard liability," is a significant contribution to both the geological and lay communities. Four important volumes on the geology of deltas, that favored habitat for petroleum accumulation, have been published. Two of these, "deltas-models for exploration and "deltas in their geologic framework" have been reprinted due to demand. The 22nd edition of "directory of oil company name changes" was printed in 2012. Two recent publications, exploration and exploitation of coastal salt basin diapiric structures in the lower pliocene through eocene trends: geology and techniques", a joint effort with the new orleans geological society, and "productive low resistivity well logs of the offshore gulf of mexico" are valuable additions to the geological literature.
The society encourages and aids students through the calvert memorial scholarship fund for graduate students, and the undergraduate scholarship fund for undergraduates. The society also gives outstanding geology student awards to stephen f. Austin university, lamar university, texas a&m university, the university of texas at austin, rice university, the university of houston, and sam houston state university; and promotes participation in the houston engineering and science fair.
The 3 programs described on its FY2024 Form 990, listed largest first by expense.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2019 to 2020, from $1.1M to $880k (−21%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2022 9%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 9 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
