Coupling of elastic isotropic medium parameters in iterative linearized inversion
An elastic isotropic medium is described with three parameters. In seismic migration the perturbation of one elastic parameter affects the images of all the three, which means that these parameters are coupled. For an effective quantitative reconstruction of the true elastic medium reflectivity one can apply an iterative linearized migration/inversion, where minimization of the misfit functional is done by the conjugate gradient method. The final result of the iterative approach can be obtained directly by Newton’s method, using the pseudo-inverse Hessian matrix.
Calculation of this matrix for a realistic model is an extremely resource-intensive problem, but for a model of a scatterer in a homogeneous elastic medium it is quite feasible. This paper presents the numerical results of elastic linearized inversion for this simple model, calculated both with iterative approach and Newton’s method. Experiments show that in the both cases the elastic parameters have coupled weaker than in the case of migration. The iterative approach allows achieving acceptable quality of the inversion, but requires a large number of iterations. For faster convergence it is necessary to use the preconditioned conjugate gradient method. The optimal preconditioning will improve the convergence of the method as well as the quality of inversion.

High-order finite-difference method to calculate wave fields in anisotropic media
This paper proposes a method of calculating 3D seismic wave fields for anisotropic elastodynamic equations. Stable finite-difference schemes up to the 8-th order inside the area and up to the 4-th orders at the boundary have been developed. Adaptive curvilinear grids have been used to calculate the complex geological models with topography. Comparison of the numerical and analytical solutions of the Lamb problem has been performed to demonstrate improvement of the accuracy in the modeling and substantial savings in computer memory along with increasing of the approximation order.

4D seismic state-of-the-art technologies for monitoring of offshore oil and gas fields development
This article analyzes the current status of the 4D seismic technology. We regret to admit that in Russia the 4D seismic is used only in one of the offshore fields on the Sakhalin shelf, while there are dozens of successful 4D seismic implementations worldwide. In the years to come, this technology is expected to expand in Russia due to accelerated development of offshore fields. The article reviews three options for the 4D seismic data acquisition in such fields: 1) consistent acquisition of conventional 3D data using a towed seismic streamer at long intervals of time; 2) regular seismic surveys with seabed seismic cables; 3) installation of the seabed fiber optic 4C system for the entire life of the field. The article compares the engineering and cost parameters of these modifications.

Field techniques in multicomponent seismic
This paper reviews the acquisition techniques used in modern multi-component surface seismic (on land and at sea bottom) and borehole seismic investigations. The advantages and drawbacks of a number of modifications of field techniques have been analyzed. Selection of surface environments and downhole sources, as well as comparisons of seismic sources have been illustrated with the observations obtained in deep wells. The article describes opportunities for integration of different seismic techniques that may result in more adequate solutions of geological and operational problems. Presurvey modeling of different types of waves has been applied to formulate recommendations on preliminary justification of shooting geometry and survey density.

Revealing and locating oil-n-gas prospective zones and objects using regional prognostic seismogeological cube – evidence from Baikit oil-n-gas bearing region
This paper presents an innovative regional seismogeological cube building technique that has been developed through integration of two methodologies such as the sediment capacity modeling methodology and the seismic and formational prognosis (SFP). This technique has been used to build such a cube for the entire Baikit region and to perform a preliminary volumetric analysis: already known oil-gas objects have been located and some new zones have been predicted in Vendian and Riphean sediments.

Seismic-geological modelling for characterisation of the Bazhenovka Fm. reservoir in the inter-well space
The paper concerns the applicability of seismic surveys to characterise the Bazhenovka Fm. reservoir rocks in the inter-well space. Seismic-geological modelling is used to check whether the available seismics can feel well-to-well porosity and permeability variations. Reference information on the Bazhenovka section structure with discriminated source and reservoir rocks is inferred from laboratory lithological and petrophysical studies of core samples. The results allow formulating precisely the objectives for interpretation of seismic data. The method is tested at a real oilfield, and the characteristic of the Bazhenovka reservoir with the use of seismic-geological modelling is proven to be efficient.

Seismic stratigraphy in Eastern Mediterranean, Northern Arabia and Russian Caspian Amphitheatre: tectonic inversion traps of hydrocarbons
Data collected in nineteen projects of 3D/2D seismics and drilling have been used to study the geological history of the Eastern Mediterranean, Northern Arabian, and Russian Caspian basins, with implications for petroleum exploration. As a result, a single seismic stratigraphic model is suggested for the Eurasian-Arabian super-basin, with key reflectors and unconformities corresponding to sealevel changes. In the new model, critical events of hydrocarbon migration, called piston-type “oil breath”, correlate with tectonic inversion events while the resulting horst-flexural uplifts become major traps of hydrocarbons. Seismic stratigraphic criteria for detecting such structural traps have been developed using examples of specific seismic sections. The approach allows predicting pay zone locations and thus reducing exploration and development risks.
