Seismic interpretation is a vital step in oil and gas industry. Choosing proper drilling locations is a major challenge to the interpreters, since an ultra-deep water oil well located below 2500 meters of water can cost dozens of millions of dollars. Volumetric curvature attributes are widely used to visualize folds, faults, among other key structures that(More)
Reflection seismology is the most commonly used method to obtain a picture of the earth interior. For the oil industry, the final goal of the seismic interpretation is the identification of possible hydrocarbon reservoirs. The detection of geological faults is a basic step in this process. Many attributes derived from the seismic data have been proposed as(More)
— What do we find in common among systems that seek to convey meaningful images to an oil reservoir interpreter, a medical doctor and an ordinary sports fan enjoying a broadcasted game on TV? They are generated by a system that processes captured signals and produces images conveying relevant information to the viewer. These processes are based on Computer(More)
This paper presents a method to track horizons in a seismic section by maximizing a cost-function that measures the similarity between the seed and the tracked samples. The dynamic programming shortest-path algorithm is used to compute in linear time the optimal path between two given picks. Tests showed satisfactory results, since horizons were correctly(More)
Seismic horizon mapping is an important step in seismic interpretation. Automatic tracking algorithms are valuable tools since manual mapping can be an extremely tiring and time consuming task. In the present work, we propose a new tracking algorithm for 2D seismic horizons based on shortest paths in Directed Acyclic Graphs. Our approach was designed to(More)
