The available seismic data often does not provide a resolution that allow for precise landing point and lateral control when drilling horizontal wells. This will leaving a high dependency to the closest well data available. Moreover, subtle stratigraphic and structural features are often not imaged properly by the available seismic data due to resolution limits. These features sometimes important to understand for supporting well planning and avoiding drilling hazards. This study demonstrates how ConocoPhillips uses an inhouse proprietary technology to improve seismic resolution for supporting landing zone, hazard determination and attribute extractions for reservoir quality mapping and distribution without any requirement for re-acquisition or complete re-processing. The methodology, Seismic Super Resolution (SSR), is described as a post-imaging inversion which is inspired by super resolution techniques from computer vision. The technology imposes a sparsity/coherency assumption on geophysical parameters by formulating a constrained minimization problem to get a higher-resolution volume from the original data. The method is independent from well data to avoid any bias, but a validation process using synthetic well data is applied to justify the result before using it for an interpretation. The product of this technology is a higher resolution seismic dataset that allows for more precise landing point and lateral control when drilling horizontal wells. The product also allowed for interpreting increasingly subtle stratigraphic and structural features. Subtle faults which were not interpretable with the original seismic dataset, within the reservoir section, became clear on this higher resolution seismic data. Spatial delineation of mass transport complexes, which are significant for reservoir quality distribution, is also improved after SSR was applied to the original seismic dataset. This study demonstrates a novel and cost-effective post imaging seismic inversion technique adapted from computer vision that shows clear value for drilling to stimulation planning and risk mitigation in the Delaware Basin. This technique also allows ConocoPhillips to better characterize reservoir distribution which beneficial for field development planning.
