... High trace density (HTD) seismic surveys are gaining popularity in the Permian Basin. They provide greater geologic detail from surface to basement. This enables oil and gas companies to further innovate shale plays. Unfortunately, not all seismic acquisition designs adequately address the needs...

... To estimate the basement depth from potential fields , we develop a Deep Learning method based on a neural network of the Feed Forward (FFNN) type. The data used to train and test the network are related to the Bishop synthetic model. The training was organized using a moving window along...

... Basement buried hill is an important target for oil and gas exploration because of its developed fractures or high porosity. It is very important to obtain high resolution imaging of basement; especially low frequency signal is the key to the imaging of the substrate. The characteristics...

... Depth-to-basement and sediment thickness estimations are relevant to the explorationists as they help to both identify potentially productive sedimentary basin areas and to map their extents. In addition, on a basin scale, a depth-to-basement map provides a constraint of paramount importance...

... The traditional way to map the interface is based on depth-to-basement inversion method, of which an important hypothesis is that geological units in and out basin are homogeneous. However, the geological situation is not the case. This paper develops a novel process of hybrid inversion...

... was carried out by mapping major reflection packages and grouping these into radar facies. We then compare these with geologic facies defined by stratigraphic descriptions examined in the excavation units. Finally, we mapped the deepest coherent, laterally extensive reflection as the basement, which appears...

... time frame for excavation. Initial excavation results identified areas of emplaced sand that correspond to the GPR anomaly detected. Using augers, KGS researchers defined the extent of this sand anomaly which led to the discovery of concrete stairs leading to an intact basement. A second GPR survey...

.... These profiles provide the clearest-yet images of Precambrian basement beneath the Illinois Basin. The purpose of our study is to present and describe basement structure from a subset of these profiles with reference to how they constrain the interpretation of previously proposed Precambrian terranes beneath...

... ABSTRACT Electromagnetic methods are established tools alongside gravity and magnetics for non-seismic mapping of crystalline basement. Accurately mapping the boundary between sedimentary cover rocks and the crystalline basement has implications for hydrocarbon prospectivity of a basin. We...

... ABSTRACT In the past, there have been many efforts to effectively delineate and study fractured basements. These focused on improving the attribute analysis of the fractures to minimize the risk. However, the accuracy of attribute analysis depends on the quality of seismic imaging...

... ABSTRACT The depth and structure of the basement is difficult to define in exploration areas where the seismic data is poor in quality. Seismic resolution degrades going deeper as signal waves are dissipated over time. A solution to this problem lead us to do a study in the offshore Borneo...
