About Us

National Petrographic Service, Inc. is an independent laboratory of geologists and technicians, specializing in the preparation of thin and polished sections for petrographic study, and sample preparation for paleontological, palynology, kerogen and vitrinite slides. We do in-house vitrinite reflectance studies as well as provide lab services for geoscientists in government and environmental agencies, university programs, concrete and materials research, engineering, petroleum exploration and production companies, and research and development departments.

High Quality Preparations
Our reputation for delivering work of the highest quality has become the hallmark of our business because we understand that the careful and accurate preparation of your samples is critical to your planning and decisions.

Fast, Reliable Service
Reliability is another reason for our good reputation. We know that when you need lab work, you need it now. That's why we work with you every step of the process, as though we were part of your own research team. Without compromising quality, we do whatever it takes to promptly deliver your samples for analysis.

Cost-Effective Laboratory
When you hire National Petrographic Service, Inc., you're gaining more than our expertise. Today, it's more cost effective to send samples to an "outside" lab than it is to secure the specialized machinery and staff of an "in-house" facility. In organizations where lab capability exists, we become an invaluable partner when large orders or specialized work threatens to overload your lab's capacity.

Drilling Well, Super Rush, Rush, and Standard Delivery
National Petrographic is proud to offer a return of samples as follows: 24 hours, Super Rush (2 - 5 days); Rush (2 weeks); Standard (4 weeks) (Subject to change - please call for current estimate on turnaround time). From our Houston location, we ship overnight anywhere in the world and hand deliver samples at any time, any place in the city.

"The quality of our work is guaranteed"
