Geophysics Services
Through our subsidiary Caspian Geophysics, we provide onshore, transition zone and marine seismic data acquisition services to both the national oil company and independent oil and gas exploration and development companies operating in Kazakhstan and the Caspian Sea. Geophysical seismic surveys have been the primary tool or method of oil and gas exploration for over fifty years. Geophysical seismic surveying refers to the making, processing and interpreting of measurements of the physical properties of the earth for the purpose of gathering data. Oil companies utilize geophysical services in the following ways:
  • To identify new areas of potential sources of hydrocarbons termed "reservoirs."
  • To determine the size and structure of reservoirs.
  • To characterize reservoirs and optimize their development.
The aim of a 2D seismic survey is to provide a series of vertical inline and crossline graphical slices of the earth that are used to identify and determine the size of a hydrocarbon reservoir. A 3D survey, utilizing a very dense grid of data, provides a continuous volume (100% coverage) of high-quality subsurface data. Both the structural and stratigraphic elements are continuously represented at a resolution not attainable in 2D surveys. Oil and gas exploration companies typically contract for geophysical services in one of two ways. First, they contract directly with the geophysical service provider. Under this format, once the survey is completed the client owns the data that is recorded. In the industry, this is termed "proprietary" work. Contracts for this type of work are structured in one of two ways. The most widely used are production contracts where we are paid for the amount of data recorded, usually counted and charged by the number of source points acquired. For any period of time that we are unable to acquire data due to circumstances outside our control, (weather for example), a standby-rate is charged to the client. The other method of contracting is based on time, where the crew can charge the time-rate for any period that the crew is technically capable and available for work. "Non-proprietary", "multi-client", or "speculative" seismic surveys are the second contracting method geophysical service companies may offer. When performing services on this basis, the data is actually acquired by the geophysical service company for its own account. The geophysical service company then licenses that data to a number of clients. The high cost involved in obtaining geophysical data on a proprietary basis has prompted many clients to license data on a multi-client basis. The geophysical industry is highly technical and the requirements and demands on acquisition and processing are continually evolving as clients seek to answer questions and understand more about their reservoirs using seismic data sets. We intend to invest in the latest available technology to allow us to offer the kinds of solutions our clients require, both in terms of capacity; as the area develops it`s licensing of new acreage, and in terms of technology; as the reservoirs themselves develop and require more detailed data acquisition and analysis. Caspian Geophysics provides geophysical services through its two subsidiaries: TatArka LLP, a wholly-owned subsidiary; and Kazmorgeophysica, CJSC, an 81% owned subsidiary Marine Seismic.
