- Detailed Research of a 250-acre property at Louisiana, USA, for the possibility of natural gas presence. Results indicated the very high probability of the presence of known gas-bearing formations such as what are referred to as the Cotton Valley Formation, Smackover Formation, Haynesville Shale, Rosston Field, and other isolated but high – yielding sedimentary layers.
- Geohydrological Study of the Marimla and Calumpang rivers in Bamban, Province of Tarlac for a Due-Diligence Study to address an Eco-Tourism Project for the Clark Development Corp. by an interested foreign investor. The study delineated a proposed wide man-made lake for water-skiing, sites for lakeside manors, six high-end hotels, two-18 holes golf courses (the first a valley golf course, the second a ridge golf course), a townsite area, a water-world resort component, and a monorail system to connect the structures.
