Environmental considerations for 3D seismic in Louisianna wetlands
Louisiana swamps have been host to seismic crews for many years. Results from recent 3D surveys indicate that well planned and executed seismic operations have a minimal and short term impact in these environmentally sensitive wetlands. Pre-planning identifies challenges that require use of improved technology and work procedures. These include multi-channel radio telemetry recording systems, ramming of dynamite and hydrophones as opposed to drilling, DGPS positioning and coordinated use of Airboats, buggies and helicopters. In addition to minimal environmental impact, increased data quality, reduced cost and shorter project duration have been achieved as a result of these efforts. Unlike 2D surveys, where profile positioning is flexible, 3D surveys involve high density coverage over many square miles operated by numerous personnel. Survey design includes minimizing repeated traffic and crossing points. Survey operations require environmental participation and commitment from every person involved in the project. This includes a thorough orientation and training program with strong emphasis on environmental sensitivity and awareness. Close co-ordination between regulatory agencies, clients and the contractor is a key factor in all aspects of the survey planning and operation. Benefits from these efforts are significant, measurable and continue to improve.
