The Stag Oilfield is located approximately 65 km northwest of Dampier and 25 km southwest of the Wandoo Oilfield near the southeastern margin of the Dampier Sub-basin, on the North West Shelf of Western Australia,.The Stag-1 discovery well was funded by Apache Energy Ltd (formerly Hadson Energy Ltd), Santos Ltd and Globex Far East in June 1993 under a farmin agreement with BHP Petroleum Pty Ltd, Norcen International Ltd and Phillips Australian Oil Co. The well intersected a gross oil column of 15.5 m within the Lower Cretaceous M. australis Sandstone. The oil column intersected at Stag-1 was thicker than the pre-drill mapped structural closure.A 3D seismic survey was acquired over the Stag area in November 1993 to define the size and extent of the accumulation. Following processing and interpretation of the data, an exploration and appraisal program was undertaken. The appraisal wells confirmed that the oil column exceeds mapped structural closure and that there is a stratigraphic component to the trapping mechanism. Two of the appraisal wells were tested; Stag-2 flowed 1050 BOPD from a 5 m vertical section and Stag-6 flowed at 6300 BOPD on pump from a 1030 m horizontal section.Evaluation of the well data indicates the M. australis Sandstone at the Stag Oilfield is genetically related to the reservoir section at the Wandoo Oilfield. The reservoir consists of bioturbated glauconitic subarkose and is interpreted to represent deposition that occurred on a quiescent broad marine shelf. Quantitative evaluation of the oil-in-place has been hampered by the effects of glauconite on wireline log, routine and special core analysis data. Petrophysical evaluation indicates that core porosities and water saturations derived from capillary pressure measurements more closely match total porosity and total water saturation than effective porosity and effective water saturation.A development plan is currently being prepared and additional appraisal drilling in the field is expected.

During the years of Soviet power, principal changes took place in the country’s wood industry, including in spatial layout development. Having the large-scale crisis in the industry in the late 1980s — 2000s and the positive changes in its functioning in recent years and the development of an industry strategy, it becomes relevant to analyze the experience of planning the spatial layout of the wood industry during the period of Stalin’s modernization, particularly during the first five-year plan. The aim of the article is to analyze the reason behind spatial layout of the Soviet wood industry during the implementation of the first five-year plan. The study is based on the modernization concept. In our research we conducted mapping of the wood industry by region as well as of planned construction of the industry facilities. It was revealed that the discussion and development of an industrialization project by the Soviet Union party-state and planning agencies in the second half of the 1920s led to increased attention to the wood industry. The sector, which enterprises were concentrated mainly in the north-west, west and central regions of the country, was set the task of increasing the volume of harvesting, export of wood and production to meet the domestic needs and the export needs of wood resources and materials. Due to weak level of development of the wood industry, the scale of these tasks required restructuring of the branch, its inclusion to the centralized economic system, the direction of large capital investments to the development of new forest areas and the construction of enterprises. It was concluded that according to the first five-year plan, the priority principles for the spatial development of the wood industry were the approach of production to forests and seaports, intrasectoral and intersectoral combining. The framework of the industry was meant to strengthen and expand by including forests to the economic turnover and building new enterprises in the European North and the Urals, where the main capital investments were sent, as well as in the Vyatka region, Transcaucasia, Siberia and the Far East.

The City

Little is necessary in terms of an introduction, since Amarna is one of the best-known settlements of ancient Egypt. The city was founded by pharaoh Amenhotep IV, known from his fifth regal year as Akhenaten, on his move away from Thebes and Memphis to found a new religious and administrative capital city. Akhenaten reigned approximately between 1348 and 1331 BC, and his principal wife was Nefertiti. Akhenaten’s direct successor appears to have been a figure named Smenkhare (or Ankhkheperure) who was married to Akhenaten’s daughter Meritaten. Like Nefertiti, Smenkhare/Ankhkheperure held the throne name Nefernefruaten. For this reason it is uncertain whether this individual was Nefertiti, who may have reigned for some years after the death of Akhenaten, possibly even with a brief co-regency, or whether this was a son or younger brother of the latter. The rule of Smenkhare/Ankhkheperure was short, and he or she was eventually succeeded by Tutankhamun. The core city of Amarna was erected on a relatively flat desert plain surrounded by cliffs on the east bank of the Nile, in Middle Egypt, approximately 60km south of the modern city of Minia, surrounded by the villages et- Till to the north and el-Hagg Qandil to the south. The site was defined by at least sixteen boundary stelae, three of which actually stand on the western bank, past the edge of the modern cultivation. In total, the city measures 12.5km north–south on the east bank between stelae X and J, and c.8.2km west–east between the projected line between stelae X and J and stela S to the far east, which also indicates approximately the longitude of the royal tomb. The distance between stelae J and F, to the far south-west, measures c.20km, and between stelae X and A, to the far north-west 19.2km. The core city, which is the part of the settlement examined in this section, was erected along the Nile, on the east bank, and it is defined by the ‘Royal Road’, a major thoroughfare running through the entire core city north–south.

Exploration And Development

The newly acquired 3,590 km2 Demeter 3D high resolution seismic survey covers most of the North West Shelf Venture (NWSV) area; a prolific hydrocarbon province with ultimate recoverable reserves of greater than 30 Tcf gas and 1.5 billion bbls of oil and natural gas liquids. The exploration and development of this area has evolved in parallel with the advent of new technologies, maturing into the present phase of revitalised development and exploration based on the Demeter 3D.The NWSV is entering a period of growing gas market demand and infrastructure expansion, combined with a more diverse and mature supply portfolio of offshore fields. A sequence of satellite fields will require optimised development over the next 5–10 years, with a large number of wells to be drilled.The NWSV area is acknowledged to be a complex seismic environment that, until recently, was imaged by a patchwork of eight vintage (1981–98) 3D seismic surveys, each acquired with different parameters. With most of the clearly defined structural highs drilled, exploration success in recent years has been modest. This is due primarily to severe seismic multiple contamination masking the more subtle and deeper exploration prospects. The poor quality and low resolution of vintage seismic data has also impeded reservoir characterisation and sub-surface modelling. These sub-surface uncertainties, together with the large planned expenditure associated with forthcoming development, justified the need for the Demeter leading edge 3D seismic acquisition and processing techniques to underpin field development planning and reserves evaluations.The objective of the Demeter 3D survey was to re-image the NWSV area with a single acquisition and processing sequence to reduce multiple contamination and improve imaging of intra-reservoir architecture. Single source (133 nominal fold), shallow solid streamer acquisition combined with five stages of demultiple and detailed velocity analysis are considered key components of Demeter.The final Demeter volumes were delivered early 2005 and already some benefits of the higher resolution data have been realised, exemplified in the following:Successful drilling of development wells on the Wanaea, Lambert and Hermes oil fields and identification of further opportunities on Wanaea-Cossack and Lambert- Hermes;Dramatic improvements in seismic data quality observed at the giant Perseus gas field helping define seven development well locations;Considerably improved definition of fluvial channel architecture in the south of the Goodwyn gas field allowing for improved well placement and understanding of reservoir distribution;Identification of new exploration prospects and reevaluation of the existing prospect portfolio. Although the Demeter data set has given significant bandwidth needed for this revitalised phase of exploration and development, there remain areas that still suffer from poor seismic imaging, providing challenges for the future application of new technologies.

Expansion of the North West Shelf Venture (NWSV) production infrastructure is driving plans for sequential development of the small satellite fields. The desire for additional gas reserves has fuelled increased exploration and appraisal drilling in recent years with encouraging results. The NWSV area is a complex geologic environment with multiple play levels, petroleum systems and trapping styles. Seismic imaging is poor in many areas, primarily due to multiple contamination. In 2004, the NWSV acquired the leading edge, regional Demeter 3D Seismic Survey. Since then, continuous application of improved processing techniques, such as 3D Surface-related Multiple Elimination (SRME) and Pre-Stack Depth Migration (PreSDM), have been key to providing significant imaging enhancements. Exploration drilling based on Demeter data resulted in three significant new gas discoveries. Pemberton–1 (2006) explored Triassic sub-cropping sands in a horst block at the southwestern end of the Rankin Trend. The well encountered an upside gas column due to the presence of intra-Mungaroo Formation shales providing a base-seal trapping geometry. Lady Nora–1 (2007) tested the fault block west of the Pemberton horst and encountered a 102 m gross gas column with gas on rock. The upside result accelerated a near term appraisal opportunity at Lady Nora–2 (2008). Persephone–1 (2006) drilled a down-thrown Legendre Formation dip closure in the Eaglehawk graben. Success relied on the sealing potential of the North Rankin Field bounding fault. In spite of pressure depletion associated with over 20 years of production, Persephone–1 encountered a 151 m gross gas column at virgin pressures and a different gas-water contact to North Rankin. The result demonstrated active and significant fault seal along the major North Rankin Field bounding fault. These recent, successful exploration wells have resulted in identification of follow-up drilling opportunities and a drive for ongoing seismic imaging improvements. The discoveries have material impacts on NWSV development plans for the Greater Western Flank and in the vicinity of the Perseus, North Rankin and Goodwyn gas fields.

The North Rankin gas field discovered in 1971, has been evaluated by a series of appraisal wells and refinement of this is underway through the use of a 3D seismic survey. Extensive production testing on two wells was used to establish reservoir fluid characteristics, inflow performance and to predict reservoir behaviour.The North Rankin 'A' platform has been constructed of a standard steel jacket design. Components of the structure were built in Japan, Singapore, Geraldton, Jervoise Bay and Adelaide. Provision exists for 34 wells to be drilled from the structure to exploit the southern end of the North Rankin field.Simultaneous drilling and producing activities are planned, requiring well survey and deviation control techniques that will provide a high level of confidence. Wells will be completed using 7 inch tubing, fire resistant christmas trees, and are designed to be produced at about 87 MMSCFD on a continuous basis. Process equipment on this platform is designed to handle 1200 MMSCFD and is intended primarily to dry the gas and condensate and to transfer gas and liquid to shore in a two phase 40 inch pipeline. The maintenance of offshore equipment is being planned to maximise the ratio between planned and unplanned work.The commencement of drilling activities is planned for mid 1983, with commissioning of process equipment occurring in the second quarter of 198 The North Rankin 'A' platform will initially supply the WA market at some 400 MMSCFD offshore gas rate, requiring 7 wells. The start of LNG exports is planned for April 1987. The intial gas for this will be derived from the North Rankin 'A' platform.

Detailed Interpretation

Commencing in 2014, Quadrant Energy and partners have undertaken an active exploration program in the Bedout Sub-basin with a 100% success rate, discovering four hydrocarbon accumulations with four wells. The primary exploration target in the basin, the Middle Triassic Lower Keraudren Formation, encompasses the reservoirs, source rocks and seals that have trapped hydrocarbons in a self-contained petroleum system. This petroleum system is older than the traditional plays on the North-West Shelf and before recent activity was very poorly understood and easily overlooked. Key reservoirs occur at burial depths of 3500–5500 m, deeper than many of the traditional plays on the North-West Shelf and exhibit variable reservoir quality. Oil and gas-condensate discovered in the first two wells, Phoenix South-1 and Roc-1, raised key questions on the preservation of effective porosity and productivity sufficient to support a commercial development. With the acquisition and detailed interpretation of 119 m of core over the Caley Member reservoir in Roc-2 and a successful drill stem test that was surface equipment constrained to 55 MMscf/d, the productive potential of this reservoir interval has been confirmed. The results of the exploration program to date, combined with acquisition of new 3D/2D seismic data, have enabled a deeper understanding of the potential of the Bedout Sub-basin. A detailed basin model has been developed and a large suite of prospects and leads are recognised across a family of hydrocarbon plays. Two key wells currently scheduled for 2018 (Phoenix South-3 and Dorado-1) will provide critical information about the scale of this opportunity.

The Article presents an analysis of the role of the media sector in the structure created by the placement of tourist routes in the subjects of the Russian Federation. The sample size was 6000 routes in all federal districts of Russia. The problem of poor service provided by the hotel services in Russia is one of the major problems hindering the development of domestic tourism. Value for money and sometimes do not match. Part of the situation could have saved the increasing competition with the hotels listed in the international circuit, which created its own rules of corporate culture, high standards of service, clearly defined for each category of hotel (in terms of stardom). However, this does not justify a revision of its marketing strategy of independent hoteliers. It is also important to pay attention to accommodation, similar to hotels and other accommodation facilities. They are also well represented in the tourist market. According to the author, the low level of service in accommodation facilities is determined not so much by the reluctance of management to improve it, as the structure of demand from tourists and tour operators, to create a product. Most of the routes, which include the need to accommodate tourists, implemented on average, in the area the day — two. At the same time, tourists do not stay in accommodation facilities for a long time and continue your route on. This circumstance serves as an incentive to change the quality of services. Moreover, the article stipulates that personal and other accommodations are well represented in the routes of major federal districts like Central, Ural, Siberia, Far East. Accommodation in hotels more common routes in the North- West, Volga, the Crimea and North Caucasian Federal District. Accommodation facilities, in this case, are the operators of the individual passive format services. However, this strategy cannot be used by all players of the hospitality industry in all federal districts. The specificity of the regions and their remoteness from each other, the price level in the field must be limiting conditions in which hoteliers could develop. It is therefore proposed that the need to actively offer ideas own hiking tour operators or actively interact with them, attracting all new, including the unorganized tourist flows.

Purpose. To analyze the significance of V. Ogorodnikov’s 1929 article on finds from Olsky (Zaviyalova) Island in the historiography of archaeological research in northeastern Russia. Results. An analysis of his published materials, in the context of the history of archaeological research in Northeast Asia in the 18th – first quarter of the 20th century shows that this was, in fact, the first professional publication on archaeological research in this part of northeast Asia. Until that time, sporadic publications about random finds and their fragmentary descriptions did not give a holistic picture of human existence in these territories. It was also the first Russian archaeological publication post-revolution on the antiquities of the north of the Far East. However, Ogorodnikov’s article, from the day of its publication, was forgotten, and in all further archaeological research, both in Northeast Asia as a whole, and on Zaviyalova Island and in Taui Bay in particular, was not mentioned and was not analyzed by the archaeologists who conducted research there, although the conclusions made by him were confirmed by further work. This, apparently, was due to the fact that although he was a well-known Siberian historian and the first Dean of the Department of History of Irkutsk University, Ogorodnikov was unjustly repressed for political reasons in 1933 and died in 1938 in a Gulag camp. Despite the fact that he was politically rehabilitated in 1957, his name has not yet returned to the historiography of archeology of Northeast Asia. This publication aims to fill this gap. The Neolithic age of the archaeological materials declared and published by Ogorodnikov, previously unforeseen and not justified by anyone for Northeast Asia, was fully confirmed by further research. Conclusion. The publication by Ogorodnikov in 1929 featuring results of the first excavations in Taui Bay on Olsky (Zaviyalova) Island is a significant milestone in archaeological research in the North-East of Russia.

     Reservoir characterization requires reliable knowledge of certain fundamental properties of the reservoir. These properties can be defined or at least inferred by log measurements, including porosity, resistivity, volume of shale, lithology, water saturation, and permeability of oil or gas. The current research is an estimate of the reservoir characteristics of Mishrif Formation in Amara Oil Field, particularly well AM-1, in south eastern Iraq. Mishrif Formation (Cenomanin-Early Touronin) is considered as the prime reservoir in Amara Oil Field. The Formation is divided into three reservoir units (MA, MB, MC). The unit MB is divided into two secondary units (MB1, MB2) while the unit MC is also divided into two secondary units (MC1, MC2). Using Geoframe software, the available well log images (sonic, density, neutron, gamma ray, spontaneous potential, and resistivity logs) were digitized and updated. Petrophysical properties, such as porosity, saturation of water, saturation of hydrocarbon, etc. were calculated and explained. The total porosity was measured using the density and neutron log, and then corrected to measure the effective porosity by the volume content of clay. Neutron -density cross-plot showed that Mishrif Formation lithology consists predominantly of limestone. The reservoir water resistivity (Rw) values of the Formation were calculated using Pickett-Plot method.
