Summary Quantitative prediction of reservoir tectonic fracture development characteristics, opening pressures, and sequences is critical in the exploration oil- gas-bearing reservoirs thus has received widespread attention. Using numerical simulations paleostress field during formation fractures rock criterion, we predict occurrence Middle Ordovician Yijianfang Formation Shunnan region Tarim Basin, China. The local fields reflected by mechanical properties obtained from core descriptions,...
Abstract Deep oil reservoirs are becoming increasingly significant fields of hydrocarbon exploration in recent decades. Hydrothermal fluid flow is deemed as a potentially crucial factor affecting the occurrence deep reservoirs, such enhancing porosity/permeability accelerating generation and thermal cracking, modifying organic properties crude oils. Understanding interplay between hydrothermal fluids oils would provide useful constraints for reconstructing accumulation processes predicting...
Due to the limitation of onboard computers relatively low storage and processing ability, current autonomous orbit determination (OD) algorithms mostly adopt sequential distributed method for navigation satellite. Such can save computing resources, however have met problem filter divergence rapid accuracy decline especially under condition less inter-satellite links (ISLs). This paper proposes a new stable centralized algorithm based on powerful high frequency measurement capability...
Atmospheric effect is one of the most intractable problems in InSAR. Approaches such as stacking SAR interferograms, permanent scatter techniques and calibration with external data sources have been suggested past to mitigate effects. In this paper, an elevation-dependent calibratory method proposed model correct atmospheric effects Test results from a meteorological station 14 continuous GPS stations over Mount Etna, Sicily show that improvement about 27.2% achieved after applied.
