Slim Hole Reservoir Characterization for Risk Reduction

PROCEEDINGS, 41st Workshop on Geothermal Reservoir Engineering Stanford University, Stanford, California, February 22-24, 2016 SGP-TR-209 1 Presented by DOSECC President Dennis Nielson, Ph.D., PG and DOSECC Associate Sabodh K. Garg, Ph.D. ABSTRACT: High initial capital requirements and subsurface risk are commonly cited as significant impediments to more widespread development of hydrothermal resources. However, expensive production wells […]

Lake Towuti

Lake Towuti Scientific Drilling Project Lake Towuti (2.5°S, 121°E) is a, 560 km2, 200-m deep tectonic lake at the downstream end of the Malili lake system, a set of five, ancient (1-2 Ma) tectonic lakes located in central Sulawesi, Indonesia. Lake Towuti’s location in central Indonesia provides an important opportunity to reconstruct long-term terrestrial paleoclimate […]

Lake Junin

Lake Junin Scientific Drilling Project Lake Junín, located at ~4100 m asl in the inner tropics of the Southern Hemisphere, is a prime target for drilling because it contains a thick (>200 m) sediment package deposited at a high rate (0.2 to 1.0 mm yrF1). Moraine mapping coupled with cosmogenic radionuclide dating indicate that paleoglaciers […]
