Sequence Stratigraphy of Kuwait Jurassic Section: An Approach to Proceed Forward

During the Jurassic Period Kuwait formed part of the northeastern Arabian Plate along the passive Tethyan margin. By the Late Jurassic it was located between three well-established sub-basins. Only a few published studies describe Kuwait’s Jurassic section in detail, and these generally refer to data and geological settings from nearby regions. The geological data often lack definite age control due to the restriction of the basin during Jurassic time and the quality of the analyzed samples. The geophysical data also has limitations when used for seismic stratigraphic studies. This work attempts to overcome these limitations and to establish the sequence stratigraphic framework for Kuwait’s Jurassic section. In 1996 KOC acquired 2-D seismic data with a grid spacing of 2 to 3 km; this data was sufficient to map potential stratigraphic traps. However, the vertical seismic resolution was insufficient to adequately interpret the Jurassic and deeper section. Moreover, inter-bed multiples con-taminated all of Kuwait’s seismic data, especially at the deep targets. KOC, in its search to resolve the above problems and limitations, has recently acquired high-resolution, 3-D sin-gle-sensor seismic data in order to properly sample the wave field and to improve both the spatial and vertical resolution. Also, several successful studies have been carried-out for multiple attenuation. Both the newly acquired and reprocessed data have good potential to form the basis for understanding the stratigraphic framework. In exploration all data counts to minimize the risk of failure. As the subsurface image becomes clearer the model can be adjusted to maximize the likelihood of success. Therefore the existing 2-D and 3-D seismic data were used to validate the model and highlight new exploration opportunities.
