TraceSeis integrates well-log and seismic data to obtain quantitative estimates of reservoir and geomechanic properties
The identification of optimum locations to place wells is fundamental in the exploitation of hydrocarbons in both, conventional and unconventional plays. For the task, the O&G industry has relied on seismic data to define subsurface structure and as an aid in quantifying reservoir (or resource) properties related to the storage and production capacity of rocks.
Quantification of reservoir properties using seismic data has pitfalls and limitations. Some of these (data fitness for example) can be addressed by the Geoscientist. Others fall outside the Geoscientist’s control – take, for example, un-detectable thin beds or the case in which changes in the reservoir properties of interest do not produce measurable changes in the seismic data.
Addressing the pitfalls, when possible, results in increased reliability of the estimated properties; whereas understanding the limitations over which there is no control helps in assessing the risk when developing a reservoir using properties computed from seismic.
TraceSeis’ approach to quantify reservoir properties includes seismic data fitness evaluation and conditioning, as well as sensitivity analysis of rock properties and seismic to changes in the reservoir properties of interest. The analysis is done including relative rock properties which do not require Low Frequency Models (LFMs) and facilitates the data transform from seismic attributes to reservoir properties.
