It is difficult to exploit low-permeability reservoirs, and CO2 flooding an effective method improve oil recovery from low permeability reservoirs. However, in the process of flooding, acidic fluids dissolved formation water will react with rock cause dissolution precipitation, resulting pores precipitates, changing evolution law seepage channels, destroying integrity, affecting effect displace...

This paper introduces instrumental photon activation analysis (IPAA) utilizing short-lived products of photonuclear reactions, mainly (γ, n) and p), initiated by bremsstrahlung from the MT-25 microtron. A rapid nondestructive IPAA method for geochemical major element is introduced as a tool basic characterization rocks. Procedures were developed parameters such beam energy irradiation-decay-cou...

In this research, petrographic and geochemical (major and trace elements) characteristics of siliciclastic rocks of the Mozduran Formation in the eastern Kopet-Dagh Basin have been carried out in order to reveal their provenance such as source area paleoweathering, parent rock composition and tectonic setting. Mozduran Formation is mainly composed of limestone and dolomite, with minor amounts o...
