Seismic Data Acquisition

Gulf began investigating three‐dimensional seismic surveys in the mid‐1960s through Gulf Research and Development Company. During the late 1960s, models were constructed to simulate acquisition and processing. Three‐dimensional (3-D) migration was achieved in the early 1970s, and Gulf began field testing 3-D seismic data acquisition in 1974. By 1978, 3-D seismic surveys were available as a commercial service through contractors. Some advantages that 3-D seismic surveys have over 2-D seismic surveys are: they can help refine both structure and stratigraphic interpretations; they assist in defining the paleogeology and reveal details otherwise not apparent; they help determine the reservoir limits through improved interpretation of the structure and hydrocarbon indicators; they enable the acquisition of subsurface control under surface obstructions, such as platforms, rigs, etc.; they provide the opportunity to construct profiles in any direction desired; and they lend themselves to interactive interpretation. When using 3-D seismic surveys, improved seismic resolution is expected. This in turn improves drilling success and finding new reserves, makes the development drilling program more efficient, and provides the best possible location for a wildcat survey. The results achieved in 16 3-D seismic surveys that cover 26 blocks in the offshore Gulf of Mexico reveal that offshore 3-D seismic surveys can be a cost‐effective way of finding and developing hydrocarbons.

An innovative tomogram processing method is presented, the interpretation of which can complement the static-model workflow. The process, in which a cube of tomographic velocities is generated and then tomograms are derived, will add to the information coming from the seismic data. The processed tomographic model provides interpretable information from the topographic surface and is an important tool for seismic characterization because, through the design processes, the resultant seismic character yields a set of interpretable data. In zones of dramatic topography, and in general with complex geology, it is possible to more reliably correlate the outcrops with the seismic data and in this way refine the final model of the area. These data can be used for the shallow exploration of hydrocarbon reservoirs or, for example, for the identification and structural monitoring of sweet-water aquifers that should be protected behind pipes in the design of well casing. Two case histories will be presented and commented on in the final section of this paper. Teamwork should improve when new technologies and new challenges are addressed collaboratively by people engaged in different disciplines related to geologic and geophysical activities.

Purpose – As the government extension services are less effective in reaching the remote areas and mid-hills of Nepal, the purpose of this paper is to examine the effectiveness of community-based management in technology transfer. Design/methodology/approach – The Farmer-to-Farmer (FtF) extension approach as a better alternative to government extension services will be adopted in the research. Findings – The FtF approach is a cost effective and sustainable service delivery mechanism for extending basic and innovative technologies to rural farmers, especially in remote areas. Even marginalized, poor and disadvantaged groups, often excluded from mainstream assistance, have better access to extension services disseminated through the FtF approach. The agriculture committees established at the Village Development Committee (VDC) level are much entrusted by the people as they facilitates their participation in the planning-to-implementation processes related to local agriculture development programmes. Consequently, there is much local support for the establishment of the local committees and the FtF approach. Several challenges remain however, one being the committee members’ management capacity. Originality/value – Decentralizing the FtF extension approach to the local level, the VDCs.
