A Prospective Method to Increase Oil Recovery in Waxy-Shallow Reservoir
Waxy oil has been the main characteristics of The X field. Initial screening criteria studies indicated that cyclic steam stimulation (CSS) would be the optimum option because favorable reservoir condition. Based on this method we would like to know how much oil gain and the effect of steam for the stimulated and surrounding well. The injection of steam was done for 7 days followed by 14 days of soaking period. 39,000 liter of Marine fuel oil was used to generate steam for stimulation with an average produce steam quality about 80%. Average of 255 MMBTU of steam was injected each day with total steam injected was about 1.7 BBTU. The oil production was increased four times from 5 bopd into 21 bopd. Proper well candidate and high permeability are some reason for this method successfully increase oil production. Additional heat from steam reduced the damage near wellbore due to wax deposition. This is verifying by increasing productivity index from 3 bbl/psi to 4 bbl/psi. From results and observation data, this method can be a platform for typical shallow depth reservoir with high paraffinic content especially other reservoir in Sihapas formation.
A scientometric study of human computer interaction research in India
The research output of India in human computer interaction (HCI) research during 1987-2011 is analyzed in this paper on several parameters including total research output, its growth, rank and global publication share, citation impact. It also analyses the characteristics of most productive institutions, authors and high-cited papers. India is at 16 th position in the world in HCI research publications with 2656 papers by 3691 Indian authors from 693 institutions of India. The Transformative activity index suggests that India′s research activity in the field of HCI is improved greatly in the last 5 years. Although highest number papers are contributed by Indian Statistical Institute, about half of publications are contributed by engineering colleges. All the papers published by Indian researchers have appeared in journals with impact factors between 0.090 and 5.211 with an average impact factor of 1.455. Indian authors preferred to publish in journals originated from United Kingdom, the Netherlands, USA and Germany. Citation analysis for Indian publications gives 9.8 citations/paper.
The Three Faces of Defeasibility in the Law
In this paper we will analyse the issue of defeasibility in the law, taking into account research carried out in philosophy, artificial intelligence and legal theory. We will adopt a very general idea of legal defeasibility, in which we will include all different ways in which certain legal conclusions may need to be abandoned, though no mistake was made in deriving them. We will argue that defeasibility in the law involves three different aspects, which we will call inference-based defeasibility, process-based defeasibility, and theory-based defeasibility. Only the integration of these three perspectives allows us to provide a satisfactory account of the role of defeasibility in legal reasoning.
