Description
Summary:The article discusses the use of spatial statistics methods for the analysis of reservoir connectivity, for the assessment of the mutual influence of wells and determining the direction of anisotropy of its properties. The analysis of the calculated values of the Moran’s correlation index showed that there is a positive spatial autoregressive dependence of the average oil production of a well with adjacent wells. Coefficients of spatial dependences are manifested more in the case of determining offset wells at a distance of up to 750 m. A spatial-panel model was built, which took into consideration the spatial and temporal lags with fixed effects in the SAC specification (model with spatial coefficient and spatial error) and allows to assess the impact on the average production of bottom hole and in-situ reservoir fluid pressure.
