3D Interpretation of Gravity Anomalies in the Potentially Promising Oil and Gas Region of Ajinohur
Abstract
This article presents the interpretation of Bouguer gravity anomalies using the 3D prism method in
the potentially promising Ajinohur oil and gas region. According to this model, the surface depth of the
crystalline basement is calculated by considering the density contrast at the bottom of the low-velocity zones in
the upper part of the Earth's crust and the quadratic dependence of the density difference on depth.The study
aims to conduct a numerical analysis of the gravity field of the potentially promising oil and gas region of
Ajinohur and develop a digital gravity model of the sedimentary layer thickness.For the interpretation of the
gravity anomalies in the potentially promising oil and gas region of Ajinohur, a sedimentary basin is viewed as a
number of prisms placed in juxtaposition. The decrease of density contrast in sedimentary basins is
approximated by a quadratic function. Based on the gravimetric field data of the studied area, the gravity model
of the sedimentary layer thickness was constructed using the GR3DSTR computer program.From the gravity
model of the sedimentary layer thickness, it was found that the maximum thickness is near Ajinohur Lake, in the
Gamigaya-Ajibulag area (16 km), and the minimum is in the structural area of Aydinbulag, Chaykend, and
Eastern Dashuz (6-8 km).The sedimentary layer thickness in the area where the Gojashen structures are located
is 8 km. The regions of negative local gravity anomalies correspond to areas where the sedimentary layer
thickness increases, such as in the Gamigaya-Ajibulag area. Conversely, a decrease in the sedimentary layer
thickness is observed in the zone of local gravity maxima (Dashuz, Aydinbulag, Gojashen). The correspondence
between the calculated sedimentary layer thickness with seismic sections and well data was also determined.The
gravity model of the sedimentary layer thickness is of practical importance in oil and gas exploration and in
selecting drilling well locations.
