The hydrocarbon accumulation regularity and the model of hydrocarbon accumulation along the fault ridges in the slope zone of the continental fault basin

Journal of Petroleum Science and Engineering, 2021
The slope zone of fault basin has a large area and high hydrocarbon potential. Its relatively highly scattered reservoirs and vastly different accumulation characteristics make it difficult to accurately determine the main controlling factors of ...

Multi-Stage Voltage Sag State Estimation Using Event-Deduction Model Corresponding to EF, EG, and EP

IEEE Transactions on Power Delivery, 2023
Knowledge of the disturbance of the concerned bus is essential to make decisions to mitigate voltage sags. The most commonly used method is to estimate the state of voltage sag in the absence of a monitor. However, the traditional state estimation method,

A New Method for Fault Location in Distribution Networks Based on Voltage Sag Measurements

IEEE Transactions on Power Delivery, 2021
This paper presents an innovative method for fault location in distribution networks based on classical circuit analyses. Two synchronized and few nonsynchronized pre- and during-fault voltages are required at few buses along with the impedancematrix.

Permian to early Triassic tectono-sedimentary evolution of the Mahu sag, Junggar Basin, western China: sedimentological implications of the transition from rifting to tectonic inversion

, 2021
The Permian to early Triassic terrestrial successions in the Mahu sag constrain the tectonic evolution of northwestern edge of the Junggar basin. This study analyzes the sequence stratigraphy of the Mahu sag in order to understand the interplay between ...
