The selection of appropriate wells for hydraulic fracturing is one of the most important decisions faced by oilfield engineers. It has significant implications for the future development of an oilfield in terms of its productivity and economics. In this study, we developed a fuzzy model for well selection that combines the major objective criteria with the subjective judgments of decision maker...

The primary components of oilfield brines (sodium and chloride) occur in groundwater naturally and from other contaminant sources. Therefore, sodium and chloride content alone are not reliable indicators of possible low-level oilfield brine impacts. Graphical methods used to evaluated chemical characteristics facilitate comparison of groups of samples (e.g., groundwater and brine) based on rela...

CO2 mediated enhanced oil recovery (CO2-EOR) may lead to methods of CO2 reduction in the atmosphere through carbon capture and storage (CCS); therefore, monitoring and verification methods are needed to ensure that CO2-EOR and CCS activities are environmentally safe and effective. This study explored vegetation growth rate to determine potential ecological effects of emissions from CO2-EOR acti...

The structure of S Oilfield Bohai sea area in China is located the low uplift slope zone Dongwa Laibei Huanghekou depression. target interval oilfield belongs to Paleogene layered structural oil reservoir under influence igneous rocks. Due widespread development rocks, and diversity rock types, complex, lateral changes are intense. differences volcanic eruption intensity materials made masses o...

Oil field assimilation needs a complex of facilities and service lines for oil recovery, transportation and refining. It includes wells, collection stations, pipelines, meters, separators, formation pressure maintenance equipment, roads and power lines. Oilfield assimilation depends on the geographical and climatic features of the field, such as the areas under existing buildings, areas taken u...

The objective of this paper is to present a unified modeling framework to address the issues of uncertainty and complex fiscal rules in the development planning of offshore oil and gas fields which involve critical investment and operational decisions. In particular, the paper emphasizes the need to have as a basis an efficient deterministic model that can account for various alternatives in th...
