ABSTRACT This article examines the development of water-swellable rubbers for oil and gas production packer equipment. The object of the investigation is to document the effect of rubber's acrylonitrile content on the swelling of the elastomers modified with sodium-carboxymethyl cellulose and a copolymer of acrylamide and potassium acrylate. After testing the samples at room temperature, the most influential factor in a material's swelling was discovered to be the mineral content in the liquids imitating well fluids. NBR polarity stemming from the inherent CN-group level was not explicitly detected to affect the swelling rate and maximum ratio under the described conditions of the experiment. It was determined that in sodium chloride aqueous solutions with concentrations from 3 to 22%, swelling of nitrile rubber mostly depends on its cross-linking degree.

Foreign exchange reserves are assets of a central bank that are stored in foreign currencies such as dollars, euros, yen and are used for international trade and funding the country's economy. The size of the country's foreign exchange reserves depends on the strength of its exports and imports both oil and gas and non-oil and gas. Regarding the purpose of this study to analyze the allocation of oil and gas and non-oil gas trade to the volatility of foreign exchange reserves in Indonesia, 1975-2016. This study used secondary data from the Badan Pusat Statistik and World Bank reports using quantitative analysis (multiple linear regression test). The results of the study show that non-oil exports and imports have a significant negative effect on the volatility of foreign exchange reserves. While for oil and gas exports and imports it has a negative and insignificant effect.

The Relationship

Large-scale projects often involve hundreds or even thousands of businesses. There are opportunities for these firms to produce innovations to solve problems and improve the project’s outcomes, but the time-bounded nature of the project and technical interdependencies also constrains innovation. Using quantitative analysis of data from firms in large oil and gas projects, we show that Teece’s sensing, seizing, and reconfiguring model of dynamic capabilities theorizes innovation in this interfirm project context. We also identify connections between these microfoundations that are not captured in Teece’s linear model, where sensing activities moderate the relationship between seizing activities and innovation.
