Summary

Three -dimensional seismic surveys help identify reserves that may not be produced optimally .The analysis can save costs by minimizing dry holes and poor producers .

Analysis

A 3-D survey shot during the evaluation phase is used to assist in the design of the development plan .
With the development and production , data are constantly being evaluated to form the basis for locating production and injection wells ,managing pressure maintenance ,and performing workovers .
These activities generate new information ( logs,cores,DST's ,etc.) that change maps , revise structure , and alter the reservoir stratigraphic model .
A 3-D seismic survey impacts the original development plan .
With the drilling of developments wells , the added information is used to refine the original interpretations .
As time passes , and the data builds , elements of the 3-D data that were initially ambiguous begin to make sense . The usefulness od a 3-D seismic survey last for the life of a reservoir. A 3-D seismic data can be used to assist to define the geometric framework , to make the qualitative and quantitative definition of the rock and fluid properties and to conduct flow surveillance
