The Alaska North Slope, within the Arctic Circle, is a challenging environment to operate seismic crews. The company has operated land and marine seismic programs on the North Slope since 1979. We present a review of the summer 2012 Simpson Lagoon seismic survey, outlining the safety, operational and technical challenges faced in an arctic transition zone environment. Ocean Bottom Seismic (OBS) data on the North Slope is essential for the effective development of the hydrocarbon fields, providing improved and accurate subsurface imaging. The arctic open-water season provides a short window of opportunity to collect OBS data, bounded by the seasonal break-up and freeze-up of the sea ice and subsistence whale hunting. These factors constrain the quantity and influence the quality of the data collected, however sufficient resource allocated to pre-season planning is critical to the success of the seismic project. We demonstrate the planning and decisions made were influenced by the safety of the seismic crew, minimizing impact to the environment, and the collection of quality seamless subsurface seismic data. Key successes of the survey include: 24 hour operations completed within 45 days; completion of the seismic objectives equating to 88 square miles of data; enhanced imaging below the lagoon barrier islands carried out by safe and efficient helicopter operations utilizing autonomous land nodes; and innovative techniques for burying receiver sensors into the surf zone which significantly improved data quality.
