The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.5 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00018 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.42 SJR: 0.217 SNIP: 0.362 CiteScore™:: 2.3 H-Index: 19

Краткое описание

Borehole ballooning-breathing is the term used to describe reversible mud losses and gains during drilling operations. In naturally fractured reservoirs borehole ballooning-breathing caused by opening/closing of natural fractures is the major mechanism of this phenomenon. An accurate model of the fracture-induced ballooning-breathing could provide an aid in mud optimization and improve the well control procedures while drilling in naturally fractured reservoirs. Using this model, the hydraulic aperture of conductive fractures can also be obtained by continuous monitoring of mud losses and gains. This paper first discusses the previous models of fracture ballooning in detail. Then a new model is developed for radial flow of mud with yield-power-law (Herschel−Bulkley) rheology in a single isolated deformable horizontal circular fracture. In this model, exponential deformation law is used for fracture deformation, which is more realistic than the simplified linear deformation law. This model is also developed for both fracture ballooning and breathing phenomena. From the developed model it is concluded that cumulative loss in the case of exponential deformations is less than that of linear deformation during fracture ballooning. This difference is due to pressure distribution in both cases. The pressure builds up faster for exponential deformation due to higher transmissibility of the fracture. The general solution for exponential deformation law in dimensionless coordinates is also presented in the form of mud loss curves for ballooning process. Shortcomings of the developed modeling approach are outlined.
