.... The direction of drilling a horizontal well section largely determines its efficiency. In complex geological conditions, a detailed analysis of seismic data in the drilling area helps to reduce drilling risks and achieve planned starting parameters. The integration of seismic data in geological models is often...

... Abstract Missing seismic data is largely present problem in the world. Lack of seismic data usually occurs due to some form of natural obstacle or legislative prohibitions of seismic exploration. Restoration of seismic data would allow locating of new oil traps and reduce the risk...

... and the corresponding lithology. The algorithm of the democratic association of neural networks DNNA was used to propagate electrofacies in the inter-well space. The method optimizes the use of seismic data before summation and after summation together with well data through a controlled process that provides...

... to the low elastic contrasts of reservoir rocks relative to the embedding sand-clay sediments, their prediction from seismic data is challenging. Additional complications are associated with the presence of a significant amount of coal material in the geological section. Minimizing the uncertainties...

... Abstract Today, the acute question is the possibility of using seismic data in the process of drilling horizontal wells, in particular, on continental deposits, which are characterized by high lithological and facies heterogeneity. In particular, the results of seismic inversion, which...

... Abstract Currently, one of the most widely used methods of extracting hard-to-recover oil reserves in Russia is drilling horizontal wells. Support for drilling horizontal boreholes is based on a 2D geonavigation section using LWD and MWD data, without taking into account 3D seismic data...

... Abstract Construction of offshore exploration wells in harsh pressure and temperature environment involves a high risk of geological complications. This is particularly relevant for exploration operations in insufficiently explored areas where the well design is based on seismic data, while...

... for a fractured reservoir, from seismic data. The main goal of this paper is to prove the efficiency of a neural network in estimating fractured medium parameters, represented as anisotropy parameters of HTI model. (HTI is "Horizontal Transverse Isotropy".) As such fracture parameters, we consider the normal...
