Abstract Nitrile rubber (NBR) has been the work-horse elastomer in oil and gas production for the past fifty years. Random seal and packer failures have been encountered in the more agressive fields. The higher temperatures and increasing percentages of hydrogen sulfide (H2S), naturally occuring or through well stimulation directly or indirectly, initiate the failure mechanism(s). Future applications of nitrile rubber in higher temperature production should only be considered after reviewing the range of potential chemical attacks that are possible by of the aqueous environment (well fluids, completion fluids and stimulation fluids). This paper briefly outlines the scope of chemical attacks that can and will be encountered.

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.

Abstract Hydraulic fracturing treatment is one of the most efficient conventional matrix stimulation techniques currently utilized in the petroleum industry. However, due to the spatiotemporal complex nature of fracture propagation in a naturally- and often times systematically fractured media, the influence of natural fractures (NF) and in situ stresses on hydraulic fracture (HF) initiation and propagation within a reservoir during the hydrofracturing process remains an important issue. Over the past 50 years of advances in the understanding of HF–NF interactions, no comprehensive revision of the state of the knowledge exists. Here, we reviewed over 140 scientific articles on investigations of HF–NF interactions, published over the past 50 years. We highlight the most commonly observed HF–NF interactions and their implications for unconventional oil and gas production. Using observational and quantitative analyses, we find that numerical modeling and simulation is the most prominent method of approach, whereas there are less publications on the experimental approach, and analytical method is the least utilized approach. Further, we suggest how HF–NF interactions can be monitored in real time on the field during a pre-frac test. Lastly, based on the results of our literature review, we recommend promising areas of investigation that may provide more profound insights into HF–NF interactions in such a way that can be directly applied to the optimization of fracture-stimulation field operations.

Oil And Gas Resources

Australia's oil and gas resources industry has made a significant contribution to the Australian economy and is expected to continue to do so over the next 15 years and beyond. While oil and gas production from Bass Strait has been the most important part of the industry in the past, offshore oil and gas production has increased strongly in northwest Australia over the past decade. Future growth in the industry is expected to be mainly associated with further strong growth in gas production for both domestic use and the export market. This paper contains an assessment of some major net economic benefits from the exploration, development and production of Australia's oil and gas resources during the period 1980 to 2010.

Stimulation Method

Hydraulic Fracturing, Proppant, Acid FracturingAbstract. Increase in the price of oil and gas during recent years have motivated oil and gas companies to focus on the methods that lead to increasing in the oil and gas production. Oil well stimulation as one of these methods includes a variety of operations that performed to improve productivity of the well. The main objective of a stimulation treatment is to increase the rate at which the formation delivers hydrocarbons naturally. Today’s well stimulation method is converted to the appropriate method in the oil and gas industry to maintain or increase of well productivity. Injection of acid to partially dissolve the rock, and hydraulic fracturing to split the rock and prop it open with proppant are two common techniques for stimulating of the wells. Deciding about selection of the best method for stimulation of the wells is related to the comprehensive evaluation of capabilities of each technique and conditions which are governed on specific job intended. In this article, we are trying to present a description about well stimulation method, methods that are employed to execute well stimulation, and application of these different techniques for stimulating of wells.

The paper analyses the situation with ensuring energy security in Russia over the past five years and provides an assessment of the nature of the transformation of the most significant threats to Russia’s energy security until 2030. It is shown that by 2030 the annual potential of fuel and fuel in the country Energy complex for the production of primary fuel and energy resources together with the import of fuel and energy to Russia will significantly exceed its domestic needs. At the same time, the ability to export Russian natural gas could be significantly reduced. The paper shows that the situation with the decline in opportunities for the production and export of natural gas in Russia is not very encouraging. There are no prerequisites for a significant increase in world prices for hydrocarbons until 2030. And at the same time, there is a constant increase in the cost of oil and gas production and transportation on average across Russia. The paper concludes that the possibilities for the development of the Russian economy through the sale of only natural resources are practically exhausted by now.
