The author's approaches to the feasibility of applying an excess-profits tax from hydrocarbon production to various types of deposits are reflected. The possibility of applying this tax in the operation of an oil field at the final stage of development is studied. A comparative assessment of the technical and economic performance of the field under consideration under the current and new tax regimes was carried out. Based on the modeling of scenarios for the development of the world oil market, its parameters have been determined, under which the development of the field using the new tax regime will ensure economic and budgetary efficiency.

In the case of self-kill of wells, the gas flow velocity in the lifting column is not sufficient for carrying to the surface of the liquid, accumulated in the wellbore. To remove liquid from the bottom of wells, solid and liquid surfactants are used. As a result of conducted studies of surfactant compositions, the components of surfactant solutions were chosen to remove liquid from the bottom of wells.

AbstractSolomonic legend evolved through four clearly perceptible stages. The first stage found in the pre-Christian literature was marked by the most primitive notions about Solomon-as-exorcist. These legends about Solomon's abilities, however, were controlled by several qualifiers. Solomon controlled the demons by means of his God-given gift of wisdom along with the aid of some archaic talismans. The second evolutionary stage which spanned the first and second centuries A.D. expanded the theme of Solomon-as-exorcist. Solomon controlled the demons with talismans (his ring, seal, shield, magic roots, incantations, magic bottles ...), but God was still seen as the ultimate source of his power. Demons were used by the exorcist solely to help build the Temple in Jerusalem. The third stage, from the late second through the fourth centuries, was a watershed in the development of Solomonic legend. Solomon-the-magician extraordinaire was first attested at this date. Solomon's source of power was no longer readily identified with God. At this stage, demons were used by Solomon to accomplish manifold tasks. The final stage of development, dominated by Muslim adaptations, expanded the theme of Solomon-the-wizard and the idea of subservient demons, to imaginative heights.

Studies on fecundity and embryo size have been frequently used to infer about the reproductive potential, embryogenesis, and the energy investment in embryo production in crustaceans. These parameters are relevant to the knowledge of life-history and diversity of reproductive strategies developed by this group. This study addressed the embryo production by the estuarine shrimp Salmoneus carvachoi Anker, 2007, a poorly known caridean shrimp. We investigated whether there was (1) a correlation between fecundity and carapace length, (2) an increase in embryo volume along the embryonic development, and (3) loss of embryos along development. In addition, we investigated whether the esternite length and height and width of the pleura of the second abdominal somite were good predictors of fecundity. A total of 53 embryo-carrying individuals were collected in December 2016 and February 2017 in a tidal mudflat from the estuary of the Paripe River, Ilha de Itamaracá, Pernambuco, Brazil. The carapace length ranged from 3.23 to 4.64 mm (3.78 ± 0.26 mm). Among those, 25 individuals had embryos in initial stage, 5 in intermediate stage and 15 in final stage. Fecundity ranged from 14 to 67 (33.65 ± 12.51 embryos) and was weakly correlated with carapace length. However, fecundity was strongly correlated with the width of the second sternite and width of the pleura of the second abdominal somite. Embryo volume increased markedly (93%) from the initial to the final stage of development. This increase might be due to water uptake to facilitate the membrane rupture at the onset of larvae hatching. There was significant loss of embryos only between the initial and intermediate stage. Future studies on the embryo production by other species of Salmoneus Holthuis, 1955 are necessary to understand and compare these aspects of reproductive biology.

Many of the largest Cenomanian gas deposits in Western Siberia are in the final stage of development. There are the liquid loading in the well and gas production decrease. The choice of artificial lift technologies is due to both the technological features of the production process at a particular field, and the economic efficiency of their application. The technology of injection foaming surfactants into the well is widespread in the world, which is characterized by a relatively low level of capital investments and a high level of efficiency, including economic efficiency. There are difficulties associated with the prediction of the pressure gradient under foam flow in a production tubing. This article describes a method for calculating the pressure gradient under foam flow. The results of applying this method for calculating pressure gradient in gas wells of one of the Russian fields on the final stage of development.

Coelenterazine chemiluminescence is now established as the most common chemistry responsible for bioluminescence in the sea, being found in seven phyla. However, the organisms which synthesize coelenterazine have yet to be identified. In order to deter-mine whether the luminous midwater shrimp Systellaspis debilis (A. Milne Edwards) (Arthropoda: Decapoda) is capable of luciferin biosynthesis, a developmental series of eggs was assayed for its luciferin, coelenterazine. The advantages of this system are that S. debilis eggs are autonomous and therefore have no external nutrient supply, the embryos can be ranked for developmental stage and the large egg size allows clutch numbers to be determined accurately. Recombinant apo-aequorin, which requires coelenterazine for luminescence, was used to quantify coelenterazine during the developmental sequence. An increase of almost two orders of magnitude was detected in coelenterazine content per egg between the first and final stage of development (mean values of 1 pmol and 71 pmol). This demonstrates de novo biosynthesis of coelenterazine for the first time.
