The purpose is a theoretical substantiation and empirical research of creatively oriented personality’s formation of a child of senior preschool age. Five components of the structure of a creatively oriented personality are outlined: emotional-volitional, intellectual-creative, motivational, social-communicative and operational. It is noted that the respondents have the highest research and exploration activity. High and medium levels of cognitive interest were recorded in n = 71 (59.1%). It is established that a significant part of children do not properly form the experience of creative activity. The profile of creatively directed personality’s formation of senior preschool age’s child on key psychological semantic parameters of the researched components which relevantly reflected a subject of research is built. It is established that the most significant correlations are observed for such indicators as creative potential, creative thinking, emotional potential (P ≤ .05; P ≤ .01) and (C ≤ .05; C ≤ .01). A significant part of children do not have a properly formed experience of creative activity. These children have difficulties in solving new, atypical, non-standard situations, which are characteristic of creative activity, which negatively affects the formation of creative personality. It is generalized that the received results of research it is expedient to operationalize in educational and professional preparation of applicants of pedagogical specialties.

Abstract In Western UAE, the Middle Cretaceous petroleum system is composed of Shilaif source, Mishrif/Tuwayil reservoir and Tuwayil/Ruwaydha seal. Oil is discovered in Tuwayil sandstone in DH and NN fields. Well correlation of Tuwayil siliciclastic interval shows high heterogeneity and rapid lithology varies. Currently, a few general studies about Tuwayil sandstone was published. However, detailed sedimentary facies, reservoir characteristics and accumulation mechanism about Tuwayil are ambiguous. Limitation on these aspects prohibits enlarging exploration activity of Tuwayil and makes barriers to deepen understanding of the whole K2 PS. To enhance understanding on Tuwayil formation, well data in DH, NN fields and adjacent area was integrated. Dedicated single well analysis, well correlation and petrophysics study were carried out. Cores were observed and laboratory outcomes including TS, SEM, RCA, MICP, XRD were adopted into this study. Furthermore, we have also utilized 2D&3D seismic to illustrate the spatial distribution of Tuwayil siliciclastic setting and interior sediment pattern. Basically, the Tuwayil sand-shale interval represents the infilling of Mishrif/Shilaif intrashelf basin and mainly deposits in the tidal flat-delta facies. The epi-continental clast is sourced from the Arabian shield and transferred from west to east. In Western UAE, the Tuwayil depocenter located in DH field, where 4-5 sand layers deposit with net pay of 30-40ft. In NN field, only one sand layer develops with net pay about 4-6ft. Through deposition cycles identification and seismic reflection observation, two sand groups could be recognized in this interval. The lower group is constrained in the depocenter and influenced by the paleo-geomorphology background. The upper group overpassed the former set and pinched out around north of NN. The Mishrif/Shilaif slope area is another potential belt to enlarge Tuwayil discovery, where stratigraphic onlap could be observed and it probably represents the sand pinch-out in lower sand group. For the K2 PS, previous study believed the shale between Tuwayil sand and Mishrif separate these two reservoirs and works as cap rock for Mishrif grainstone. This study suggests that this shale is too thin and not continuous enough to hold the hydrocarbon in Mishrif. On that note, Tuwayil sand and Mishrif belong to the same petroleum system in NN and may have the same OWC. In the NN field, it is quite crucial to consider the extension of Tuwayil sand during evaluating the stratigraphic prospect of Mishrif because the hydrocarbon is mostly likely charged Tuwayil sand first and then gets into underlain Mishrif. This study provides updates and understandings on sedimentary facies, depositional pattern, hydrocarbon accumulation mechanism, reservoir extension and potential identification of Tuwayil formation, which has inspiring implications for the whole K2 PS and could also de-risk the further exploration activity in Western UAE.

The exploration history of the large East Mediterranean Basin, which encompasses the Nile delta, Levantine, Herodotus and Eratosthenes provinces, has seen several phases of rejuvenation since exploration started in the 1950s, with new plays opened repeatedly after the basin was considered mature by the industry. The 584 exploration wells drilled to date have discovered more than 23 Bboe recoverable reserves/resources, mostly gas. The first discovery was the Abu Madi Field, in 1967, which opened the Messinian clastic play. Over time, other plays and sub plays were opened, including the Serravallian-Tortonian, the Plio-Pleistocene, the Oligo/Miocene in the Levantine, the intra Oligocene and the Cretaceous carbonates (Zohr discovery, 2015). The exceptional variety of plays, with different trapping styles, reservoir and seal facies patterns has few equivalents worldwide and makes the region a valuable training ground for explorers. The geological variety is not the only reason for such a complex and episodic exploration history: commercial (gas market) and geopolitical issues have also had an impact on the activity in parts of the basin. The largest discoveries have been made in the last 10 years (Tamar, Leviathan, Zohr) and, despite the intense exploration activity, parts of the basin remain underexplored. The company with the longest and most successful play opening history in the basin is Eni. Today, most major oil companies are active in the basin, which even after 70 years is still considered one of the world's exploration hotspots.

Abstract Oil and gas companies’ future production profile is shaped by their exploration strategy and resource base development. Gazprom Neft's production profile will include 40% of current exploration projects by 2030. Geological exploration, on the other hand, is a high-risk business because it involves a lot of uncertainty due to the geological complexity of the targets being explored, as well as a lot of risky capital. Taking these factors into account, the Company will need to expand its exploration function as well as its approaches to managing exploration projects in order to meet its lofty aims. To determine the key areas of growth and a strategy for the exploration function development in the coming years, it was decided to first analyze the geological exploration activity in the Company in 2010 – 2020 period. The knowledge of achievements, success stories, and development areas is the fulcrum for future victories. Therefore, retrospective analysis is an important tool for the development of any system of activity - individual, organization, or state.

ABSTRACT On behalf of the operators on the Norwegian Continental Shelf, the Norwegian Clean Seas Association for Operating Companies (NOFO) has the responsibility for providing a documented and verified level of oil spill response, fulfilling the requirements set by the regulatory authorities for each individual production and exploration activity. To meet this responsibility and document the established oil spill preparedness, a comprehensive and cross-disciplinary project has been undertaken, integrating results and lessons learned from oil on water exercises and test facilities in the period 1985 to 2018. The structured results feed into standardized algorithms for system capability and operational windows, applicable across all combat methods in the NOFO toolbox. Through gap and sensitivity assessments, topics for R & D area prioritisation are identified. Data and information are structured in order to fit into the assessment methodology for Environmental Risk Assessments (ERA) and Spill Impact Mitigation Assessments (SIMA), and a step by step methodology for oil spill response assessments (OSRA) was developed as part of the project, facilitating standardised and comparable oil spill response plans. In addition to this standardisation and documentation process, templates for presentation of key data for oil spill response planning purposes are developed, and disseminated to a dedicated web site, as well as the NOFO Common Operating Picture GIS. In this way, a cohesive set of data and standards are available for use in assessments, planning, authority assessment and in incidents.

The discovery of crude oil in Oloibiri-a town in the present Bayelsa state, Niger-Delta region of Nigeria) in 1956 and the subsequent exploration activities have over the years impacted tremendously not only on the ecosystem and livelihood pattern of the Niger Delta but on the pattern of conflicts that has trended.. While resources accruable to Nigeria from sale of crude oil are shared by all, the impacts of oil spill an offshoot of crude oil exploration activities are borne solely by the Niger Delta region. Oil spill appears to have found a permanent abode in Bayelsa state; from Southern Ijaw to Sagbama local governments, Olodiama to Azuzuama communities. Local communities are faced with the problem of continuous oil spill. This in turn has brought about conflicts between oil bearing communities and oil companies. These conflicts in some instances led to shut down of operations of oil companies, vandalism, and reduction of Nigeria’s crude export. In view of the illustrated background, this study examined the strategies for management of oil spill related conflicts in Bayelsa state regarding that oil spill is a key impact of crude oil exploration activity. Findings revealed that the strategies deployed in the management of oil spill in the state can be categorised into three: community strategies, regulators and non-governmental organisations strategies.

Relevance. Metals are transported by run-off from human settlements and industrial plants and accumulate in the sediments of water bodies. Lead is found in high concentrations in the soil of agricultural land. Lead can be transported with water, seafood, animal products and plants to humans. Poisoning may occur in workers and in the population in contact with lead. At the same time, hypothyroidism is a widespread disease, often due to living in areas of endemic iodine deficiency in water and soil. Latent hypothyroidism can aggravate occupational effects of heavy metals in exposed workers.Intention. To study behavioural and morphological changes in rats with lead poisoning aggravated by medicinal hypothyroidism. Methodology. 32 albino outbred adult male rats were studied. Lead poisoning was induced by lead acetate at a dose of 60 mg/kg body weight in drinking water tanks for 30 days. Hypothyroidism in rats was induced from the ninth day of the experiment with daily injections of thyrozol (thyroid static substance) at a dose of 30 mg/kg for 21 days. Behavioral responses in rats were studied using open field tests, and survey records were processed using Real Timer. For morphological analysis, layered serial cuts of brain tissue were prepared and painted using the Nissl method, and slides were visualized via observation microscopy.Results and Discussion. Under lead poisoning, animals demonstrated decreased locomotor and exploration activity and increased anxiety with increasing intoxication combined with hypothyroidism. Changes in the rat brain after exposure to lead were confirmed histologically: increased neuron degeneration, neuronophagia and glyosis. New histological data were obtained in case of lead-thyrozol combination: increased neuronal death, decreased number of astroglial cells compared to animals exposed to lead only. This suggests predominant irreversible neurodegeneration due to combined effects of lead poisoning and thyroidstatic exposure.Conclusion. Under combined exposure to lead and tyrozol, the thyroidstatic substance exacerbated decline in locomotor and exploration activity as well as lead-associated neurodegenerative processes in the rat brain.

PT. Trimegah Bangun Persada intends to do mining activity at the north part of IUP as the south and west parts have already been mined. This research aimed at producing natural resources of laterite nickel in the advanced exploration activity of Tangkuban Block. Besides, it also compared and determined the estimation methods having a good correlation with drilling results. Tangkuban Block carried out core drilling within total drill numbers of 286 spots and space distance 25 meters at the block area 22.16 Ha. This research began with determining the geological domain consisting of limonite, saprolite, and bedrock through a geo-statistical approach. After that, the researcher estimated nickel resources by three methods namely ordinary kriging, inverse distance weight, and nearest neighbor point. The result of estimation by ordinary kriging obtained a total volume of limonite layer 1,345,313 m3 with the content average of 1%, while the total volume of saprolite layer was 1,850,000 m3 1.64%.
