A quantitative basis for evaluating exploration acreage can be provided at all stages of petroleum exploration.Treating each main sedimentary sequence separately, the volume of sediments concerned is calculated or estimated, and factors based on industry experience and personal judgement are applied to this volume of generated, movable, trapped, discoverable, and producible hydrocarbons, expressed as oil.The present value of these inferred reserves is calculated by assessing the likely profit per barrel (in the local situation) and discounting this over the likely period before half of the reserves are produced.From the present value, the maximum economic expenditure on land acquisition plus exploration can be indicated.As exploration proceeds, new information can be used to revise the estimate of inferred reserves and, if the economic environment changes, the current value can also be revised.Particularly where land acquisition is costly such economic assessment can place proper limits on the price payable for land at all stages of exploration and thus avoid the situation where production success is not followed within a reasonable period by profitability.

Sedimentary Sequence

Abstract The Longobucco area displays a secondary sedimentary basin transgressive on a granite-phyllite basement. The sedimentary sequence begins with lower Jurassic quartzose conglomerate containing granite and phyllite. The conglomerate is overlain by a homogeneous calcareous marl which forms a large part of the basin and has been divided into lower, middle and upper Liassic (lower Jurassic) by dating with brachiopods, pelecypods and cephalopods. The middle Jurassic consists of red limestones of the Torrente Colognati valley. Cretaceous rocks are not present, probably because of erosion rather than non-deposition. Tertiary rocks begin with either the Paleocene or Eocene as evidenced by the abundance of Distichoplax in the microfauna.

Value Analysis

Due to the increasing installed power of the intermittent renewable energy sources in the European Union, increasing the operation flexibility of the generating units in the system is necessary. This is particularly important for systems with relatively large installed power of wind and solar. Plasma technologies can be used for that purpose. Nonetheless, the wide implementation of such technology should be economically justified. This paper shows that the use of plasma systems for increasing the flexibility of power units can be economically feasible, based on the results of a net present value analysis. The cost of the installation itself had a marginal effect on the results of the net present value analysis. Based on the performed analysis, the ability to lower the technical minimum of the power unit and the relationship between such a technical minimum and the installed power of a plasma system can be considered decisive factors influencing the economics of the investment for such an installation. Further research on better means of prediction of the minimum attainable load, which would allow determining the influence of implementation of a plasma system, is recommended. This will be the decisive factor behind future decisions regarding investing in such systems.

Considers the economic assessment of the soil. Such indicators as a quality of soil score, tariff category and coefficients for various land acquisition purposes were used as an estimate. The object of study is the irrigated soils of Azerbaijan, which are used for sowing cotton. The price of a hectare of soil was calculated by multiplying the quality of soil score by the tariff for 1 point depending on the soil category. In conclusion, it is concluded that irrigated grey–meadow soils have a yield grade of 100, irrigated meadow–grey — 91 points and irrigated chestnut soils 99 points.

Value Of Money

The time value of money is associated with the current value and future value because the money received now is more worth than the money received in the future. However, is the concept of time value of money is appropriate and justified by the Shari'ah? The time value of money is a concept that says that the money of the one rupiah that can be received today is more worth than one rupiah which will be received in the future time. The concept of time value of money is needed by financial managers in making decision when will invest in an asset and determine the source of loan funds that will be chosen. Methods for the time value of money pervade; a) the method of average rate of return. This method measures the level of profit gained by an investment. The disadvantage of this method is ignoring the time value of money; b) the payback period method. The method measures how fast the investment return is, the sooner the better; c) method of net present value (NPV). This method calculates quarrel between the current value of investment and the present value of net cash receipts in the future and calculates quarrel between the present value of cash outflow (investment) and cash inflow (income) per year; d) profitability index method (PI). This method calculates ratio between the present value of net cash receipts in the future and the present value of the investment; and e) the methods of internal rate of return (IRR).  If IRR > saving or profit required → decent. Islam views money as a flow concept. Money must rotate in an economy and may not be idle for too long time. Moreover, it lets for years. Islam does not recognize the method of time value of money because this method adds value to money solely with increasing time and not effort. Islam actually knows the money value of time; that is the time has economic value as well as the money value of money. Imam Nawawi provides definition related to value addition for money based solely on the value of time is the category of riba.

Biogas is a promising renewable energy resource produced by using anaerobic digestion of organic substrates and it is mainly used to generate electricity by means of biogas engines. Other potential utilisations are growing, e.g. grid injection and biofuels production but, generally, a treatment aimed to increase its quality is mandatory and greater investments are generally required to produce upgraded biogas (biomethane). Despite the increasing of interest on these applications, a lack of information is still present from an economic point of view. The present paper performs an extended economic assessment of upgrading and selling biogas starting from a typical farm-based anaerobic digestion plant in Northern Ireland assumed as reference. Several economic indexes have been considered to assess the economic performance of the upgraded anaerobic digestion plant, namely net present value, pay-back period, profitability index and internal rate of return. Moreover, different scenarios in terms of fossil fuel prices have been analysed. The results show that producing and selling biomethane can be economically feasible if an adequate market is fostered. Optimum anaerobic digestion sizes between 26.9 and 64.4 tonne/y have been found, with correspondent net present value and pay-back period values in the range of £6.7–64.4M and 2.8–7.5 years, respectively, depending on the price scenarios analysed and the economic index chosen. Generally, adopting the net present value as objective function of the optimisation leads to greater anaerobic digestion size than the other indexes for any price scenarios considered. Finally, tougher market conditions (i.e. higher fossil fuel prices) lead to better economic performances of the upgraded anaerobic digestion configuration.

AbstractHere we present a new site in the Sierra de Atapuerca (Burgos, Spain): Galería de las Estatuas (GE), which provides new information about Mousterian occupations in the Iberian Plateau. The GE was an ancient entrance to the cave system, which is currently closed and sealed by a stalagmitic crust, below which a detritic sedimentary sequence of more than 2 m is found. This has been divided into five litostratigraphic units with a rich assemblage of faunal and lithic remains of clear Mousterian affinity. Radiocarbon dates provide minimum ages and suggest occupations older than 4514C ka BP. The palynological analysis detected a landscape change to increased tree coverage, which suggests that the sequence recorded a warming episode. The macromammal assemblage is composed of both ungulates (mainly red deer and equids) and carnivores. Taphonomic analysis reveals both anthropic, and to a lesser extent, carnivore activities. The GE was occupied by Neanderthals and also sporadically by carnivores. This new site broadens the information available regarding different human occupations at the Sierra de Atapuerca, which emphasizes the importance of this site-complex for understanding human evolution in Western Europe.

The Otish gabbro sills intrude Aphebian clastic rocks lying uncanformably on the Archean rocks of the Superior Province close to its juncture with the Grenville Province. The sills are undated but by inference may be ca. 1750 Ma. Two dyke swarms are known in the vicinity, the 1950 Ma, northwest-trending Mistassini dykes and a northeast-trending swarm of unknown age extending 600 km from Senneterre to the Otish Mountains and possibly another 300 km to the northeast. The trends of feeder dykes to the Otish sills are physically compatible with the dominant northeast dykes, which are therefore considered to be the feeders and should be called the Otish dykes.The Otish sills appear to be a unique occurrence along the 900 km dyke trend, possibly, but not entirely because of the chances of preservation. The general form of the Otish sill complex is a triangle bounded on the north by the east–west lip of the sedimentary basin, on the southwest by a northwest-trending Otish feeder dyke, and on the southeast by the underlying northeast feeder dykes. These dykes segment the sills into a series of four or five separate intrusive complexes, small in the northwest and becoming larger to the southeast. The regular inclination of tension fractures in the basal chilled margin of the sills suggests a crude pattern of flow from the feeder dykes inward to the centre of the sheets.Interpretation of the sedimentary sequence indicates that the Otish clastics were deposited higher on the paleoslope than the Mistassini carbonates. Although few dykes intrude the deeper basin, the magma rose and formed sills within the higher sequence. This variation may be explained by the different mechanical character of the two types of cover rock controlling the dyke behaviour. The relatively plasto-viscous Mistassini carbonate–shale sequence resisted the formation of tension fractures, whereas the brittle elastics opened easily, allowing the magma to rise into the stratified sequence, forming the sill complexes.

This study aims to determine the value of land that has been released whether it affects the value of land and determine the use of money from land acquisition in Tonsewer Selatan Village, Tompaso Barat Sub-district. This research was conducted in three months, from September to November 2019. The sampling method in this study uses a non-probability sampling technique or census sampling. The samples used in this study were 13 respondents, namely all farmers who own agricultural land who have sold their land so that land conversion has occurred. In this study using primary data obtained from direct interviews with respondents using a list of questions that have been prepared. Secondary data obtained from relevant agencies. The results showed that the value of the land acquired was higher in value than the present land value. This means that the value of land that has been acquired affects the current value of land. The money from the land acquisition has been used for various purposes, namely: for business capital, buying new land, saving, buying vehicles, renovating houses, and for daily needs.*eprm*
