Geology and Development History of Swanson River Field, Cook Inlet, Alaska
The Swanson River oil field was discovered in 1957 by Richfield Oil Corporation with the drilling of the Swanson River Unit No. 1 well. The timing and significance of this discovery sparked an Alaskan industry and demonstrated the territory’sability to develop its own mineral resources and helped pave the way to Alaskan statehood in 1959. Development of the Swanson River field has progressed through a number of stages. The initial development phase of Hemlock oil (1957-1962) was supplemented by a gas pressure maintenance program from 1962 to 1998. Peak production of 38,000 BOPD was reached in 1966 with the onset of full-field compression, and current field production is 600 BOPD and 2.5 MMCFD of natural gas from 21 active wells. Along with continued delineation of Miocene-aged gas reservoirs, development of lower Tyonek G-Zone oil and production of Hemlock blowdown gas began in the mid-1990s and continues through the present. In 2001, gas storage operations were implemented along with ongoing oil and gas production, allowing Swanson River to continue playing a significant role in meeting the increasing demand for gas in the Cook Inlet area.

Oil and Gas Fields of the Cook Inlet Basin, Alaska
This volume is designed to showcase the geo-technical elements of oil and gas fields of the Cook Inlet Basin of southcentral Alaska. It contains 10 chapters written by 16 authors and co-authors who have extensive experience in the basin. All of the papers have been peer-reviewed. The first three chapters provide an introduction to exploration, stratigraphy, petroleum systems, seismic acquisition, and reservoirs of the basin. Following these are seven chapters that describe individual fields in detail. This volume is intended to serve as a key reference to the petroleum geology of the Cook Inlet Basin for a wide audience including oil and gas explorers, technical professionals, students and those seeking more information about the origin and habitat of oil and gas in the area.
