Seismic interpretation

Transtensional faults are well developed in the S Block of the South Asia area, which have an important impact on the hydrocarbon accumulation. However, the transtensional fault structure is very complex. Based on drilling and seismic data interpretation results, faults are divided into three typical types in the Lower Cretaceous, which can help to understand the complex fault system. The main faults are distributed in the NNW-SSE direction and parallel arrangement with dextral strike-slip shear characteristics, which determines the development of the tectonic belt.

A geological interpretation of the faulting mechanism is also proposed. The existence of a new unknown source in an intermontane area is problematic. The role of inherited alpine structures seems more important today than in the past. The strike of the two new seismogenic sources, responsible for the two strongest events of the 2021 earthquake succession, differs from the previously known active faults. This forces us to reconsider older views on the direction of development of active faults and the orientation of the stress field.

Identification of fracture zone is a challenging task without the image log data. There are many brownfields around the world where the image log has not been acquired; therefore, there must be an alternative way of fracture identification. In this paper, a conventional log response technique for fracture delineation has been discussed. The study area lies in the Upper Indus Basin of Pakistan, which is sub-divided into the Kohat and Potwar basins. Minwal-X-1 of Joya Mair area, which lies in the Potwar Basin, is selected for this purpose.

Bài viết giới thiệu phương pháp minh giải địa chấn toàn phần (global seismic interpretation method) được phát triển bởi Pauget và nnk. [1]. Mô hình 3D thời gian địa chất tương đối (3D relative geologic time, RGT) được xây dựng trực tiếp từ tài liệu địa chấn là kết quả của phương pháp này. Trong mô hình RGT, tuổi địa chất có sự tiếp diễn liên tục, được nội suy và xác định trên mọi điểm của tài liệu địa chấn 3D.

Whereas current building codes legally apply to seismic design of tall buildings, their prescriptive provisions do not adequately address many critical aspects. Performance-based engineering provides a desirable alternative.
