Eighteen months of research and development have conclusively proven that helicopters are playing an important part in gravity and seismic operations in remote areas, such as southern Louisiana marshlands, jungles, and mountainous areas where transportation is a difficult problem. Airborne gravity and seismic operations are successfully being carried on with resulting increased production and lowered costs. Discussions on techniques used in gravity and seismic airborne operations, plus a film showing actual field operations as well as flight performance, load-carrying abilities, landing areas, weather restrictions, and maintenance requirements for mobile operations and the possible uses of the helicopter in the oil industry, will be discussed in detail.
