The Chukchi Basin has estimated recoverable reserves of more than 29 billion BOE (MMS, 2006), but, historically, the basement geology of the Chukchi basin has been poorly imaged by insufficient seismic surveys.

Designed to deliver insight into the regional framework of the Chukchi and north Chukchi Basins, ION acquired ChukchiSPAN in 2006. It consists of over 3,000 km of 2D seismic data in the U.S. zone of the Chukchi Sea. By tying into the five critical wells in the Chukchi Basin, the program is able to better define the resource potential of the region's petroleum systems from the Barrow Arch in the east to the Russian border in the west. This program offers new insights and play concepts of what is anticipated to be a prolific region.

Program Objectives

  • Image down to the base of the crust
  • Enable regional mapping of the Moho discontinuity and the top of the crystalline basement
  • Identify the major stratigraphic sequences extending out from the petroliferous North Slope
  • Interpret the pre-Mississippian rifting and compressional history of the area

Key Components

  • Program design and layout driven by known geology and client input
  • Designed for ultra-deep imaging to the base of the crust using 9 km cables, 18-second recording and depth processing (PreSDM) to 40 km
  • Integrated geologic and geophysical interpretation
  • Provides a consistent seismic regional framework that ties in existing seismic lines
  • Improved understanding of key geologic features and places them in a basin-wide context
