The North East Java Basin is known to be one of the basins that consist of Miocene carbonate rocks, like the reef carbonate of Tuban Formation. It has the potential hydrocarbons that can be explored. Therefore, the FMI log analysis is very important to identify carbonate rocks of Tuban Formation to know facies and characteristics of that carbonate rocks. The method used descriptive and analysis process of FMI and Gamma Ray log to determine facies of the carbonate rock and the system tract. Based on the result of FMI log analysis, there are variations lithofasies include mudstone, wackestone, packstone, grainstone, floatstone, rudstone and claystone. A collection of rock associations can interpret the reef facies. It involves back reef facies, reef core facies, and fore reef facies. The changes of lithofasies and reef facies are caused by sea level fluctuations and subsidence resulting in the system tract. The system tracts generated in the research area include transgressive and highstand system tract.

The following research took place in the Jamprong area, Tuban Regency, East Java Province within a study area of 2 km2. Physiographically, the study area is situated in the anticlinorium of the Rembang Zone. This research aims to define the reservoir potential of outcrop samples from the Ngrayong Formation as an analogue for the subsurface. In addition, the depositional environment and the age of the rock in the research area was determined. The Ngrayong Formation is regarded as a potential reservoir in the North East Java Basin. The accumulated data consists of stratigraphy, petrographic analysisand paleontological analysis of rock samples, and geological mapping has been carried out to determine the distribution of rocks. Facies were determined based on outcrop observations and comprise predominantly arkose sandstone facies with fine – coarse grained, moderately sorted and with cross-bedding, herringbone, and lamination, and another facies namely massive carbonate grainstone. Based on these facies, the interpreted depositional environment is the transition of tidal flat to shallow marine carbonate platform with relative biostratigraphic age of Middle Miocene, Langhian to Serravallian (M6-M8 planktonic foraminiferal biozones). Rocks in the study area have porosity >20% or very good and permeability >130 or fair based on petrographic observations, and this supports the interpretation of the Ngrayong Formations as a potential reservoir of hydrocarbons.

Lexical indicators of the hypothetical modality in the Lithuanian local dialect of Puńsk with references to Polish and Lithuanian.The dissertation discusses the problem of lexical indicators of the hypothetical modality in the Lithuanian local dialect of Puńsk. The Lithuanian local dialect of Puńsk is used by the Lithuanians living in the north-east regions of Poland. In these very regions there run important ethnic borders between Slavs and Balts, and between the Eastern and the Western groups of Slavs. The author has applied the method of theoretical contrastive studies to characterize the local dialect of Puńsk. To begin with, the author forms the definition of the hypothetical modality along with its paraphrase. She analyzes the gradation of the hypothetical modality phenomenon. Therefore, she has distinguished 6 groups, each of which is characterized by a different degree of probability. Furthermore, she gives examples of all possible indicators of the hypothetical modality in the local dialect: lexical, morphological and syntactic, where lexical indicators are more precisely described. She has distinguished the differences and resemblances between the local dialect and the literary languages of Lithuanian and Polish. In the research area, she applies the experimental corpus of the local dialect of Puńsk. Лексические средства гипотетичности в литовском говоре окрестностей Пунска в сопоставлении с польским и литовским языкамиВ статье описывается проблема лексических показателей гипотетической модальности в литовском говоре окрес тностей Пунска. На литовском говоре окрестностей Пунска говорят литовцы проживающие на северо-востоке Польши. Именно там, на этой территории, многие столетия пересекаются этнические границы между славянами и балтами, между западными и восточными славянами. В статье используется метод теоретического сопоставления естественных языков с использованием так называемого языка-посредника (tertium comparationis). В самом начале представлено содержание категории гипотетической модальности и ее парафраза. Затем описывается изменение по степеням возможности и в связи с тем выделяются шесть групп, которые постепенно отражают повышение возможности, уверенности говорящего к высказываемому им самим содержанию. В описании гипотетической модальности упоминаются лексические, морфологические и синтаксические средства выражения гипотетических значений. Более точно описываются лексические средства. Обращается внимание на сходства и различия между говором и польским и литовским языками. В исследованиях используются данные экспериментального корпуса говора окрестностей Пунска.

Abstract the aim of this article is the description of lithofacies characteristics of sediments forming the north-east part of the morainic upland edge zone in the vicinity of Piaski Pomorskie (west Pomerania). the paper undertake also an attempt to reconstruct paleogeographical conditions of the formation of moranic uppland edge. The diversification of glaciofluvial and fluvial processes during the phase of stagnation and recession of uppervistulian ice-sheet in the vicinity of Piaski Pomorskie (western Pomerania) led to the formation of a morainic upland edge distinctly marked in morphology The edge zone separates the undulating moraine plateau from a lower situated Dębnica River Valley. This area is mostly formed by fine-grained sands with occasional layers of a coarser fraction of gravel and coarse- and medium-grained sands. The observed type of low-angle cross-stratification and trough cross-stratification indicates the dominance of diversified energy depositional environment with considerable power of water as transporting medium. the research area was formed at the front of the ice-sheet, which receded from the nearby reach of the Pomeranian Phase of the weichselian glaciation.

Research with 2D seismic data and wells used for acoustic impedance (AI) seismic inversion analysis and seismic attribute analysis has been carried out in the "CLM" Field of the North West Java Basin. The purpose of this study is to obtain the distribution pattern of acoustic impedance in the carbonate reservoir and to determine the hydrocarbon prospect zone in the study area. The acoustic impedance distribution pattern is obtained by the AI inversion process carried out on 15 2D post-stack seismic lines and 2 wells. Meanwhile, the identification of hydrocarbon prospect zones is carried out by integrating 3 maps, namely acoustic impedance slice maps, RMS amplitude attribute slice maps and envelope attribute slice maps. Based on the results of the acoustic impedance seismic inversion, it was found that the target reservoir zone in the Upper Cibulakan Formation was carbonate that had high AI values with a range of 42500-52500 (ft/s)(g/cc). Sandstone has a moderate AI value with a range of 34000-42500 (ft/s)(g/cc) and shale has a low AI value with a range of 21000-34000 (ft/s)(g/cc) which has the potential to become a seal rock. Meanwhile, based on the results of the analysis of seismic attributes, the hydrocarbon prospect zone is located in the northeast and northwest of the ITSNU-2 well location in the "CLM" field in the research area

“MRD” field is an oil and gas field which located in Rembang Zone. One of the hydrocarbon zones in this fieldlies in Ngimbang Formation. Reservoir in this field has a lifespan of Middle Eocene to Early Oligocene. Reservoir of this formation is carbonate rocks and dominated by calcite and dolomite minerals. One of the uniqueness of this kind of reservoir is the pore shape which quite complex. In this study, reservoir characterization which performed on this field is based on elastic properties modelling. Elastic Properties modelling which was conducted in this field can provide an output of the pore shape, aspect ratio, and the fraction of each respective poresforms that exist in this field’s reservoir zone. Therefore the primary data such as petrophysical data, XRD (X-Ray Diffraction), and the data of other reservoir parameters are needed for more accurate resultsobtained with real conditions. The result of this modelling shows that the shape of the pores in the reservoir zone at any depth can be predicted. Distribution of pore shapes that exist in the two wells can be used as a reference for prospective determination of hydrocarbon zones in “MRD” field.

Ras a1 Khaimah is the most northerly of the seven states comprising the United Arab Emirates and its Ruler, H. H. Sheikh Saqr bin Mohammad al-Qasimi, is keenly interested in the history of the state and its people. Survey carried out there jointly with Dr D. B. Doe in 1968 had focused attention on the site of JuIfar which lies just north of the present town of Ras a1 Khaimah (de Cardi, 1971, 230-2). Julfar was in existence in Abbasid times and its importance as an entrep6t during the sixteenth and seventeenth centuries-the Portuguese Period-is reflected by the quantity and variety of imported wares to be found among the ruins of the city. Most of the sites discovered during the survey dated from that period but a group of cairns near Ghalilah and some long gabled graves in the Shimal area to the north-east of the date-groves behind Ras a1 Khaimah (map, FIG. I) clearly represented a more distant past.
