The controlling factors and principles which govern the spatial and chronological distribution of turbidite sandstones have been investigated based on the results of sedimentological, petrographical, and mathematical analyses on the Neogene and Quaternary turbidite sandstones in the forearc and backarc basins, central Japan. Main conclusions are as follows:1) The sedimentological research revealed that the three-dimensional forms of individual turbidite sandstone beds, which are part of a depositional lobe of submarine fan system and regionally correlated bed by bed by using many useful tuff key beds, are similar to each other. The similarity continues vertically within the interval of a single depositional lobe or of a certain stratigraphic unit. Their thickness and distribution area reflect the magnitude of turbidity currents, while their form greatly depends on the grain size distribution of the sediments.2) The petrographical research proved that the heavy mineral composition can be used as a good indicator to recognize turbidite sandstone bodies which share a single source area, and are useful to check the original relationship of turbidite sandstone bodies isolated each other.3) The mathematical research led to the conclusion that the development of turbidite sandstones is controlled by the global changes such as the eustaic sea level changes, because the periodicity in an order same as the Milankovitch's cycles was recognized in the vertical change of number and total thickness of turbidite sandstone beds within an interval delineated by a certain accumulated thickness of hemipelagite in several turbidite successions.

The middle parts in Niigata Prefecture including major oil fields exists as the most remarkable area, and these oil fields mainly belongs to Bodaiji-Kamo Uplift and Kakuda-Yahiko Uplift was grown after Teradomari stage in Neogene Tertiary age. In this paper are disscussed how have developed historicaly and structurely, and then as the conclusion for migration and accumulation of oil from these area introduced following two important points: (1) The end of the regional migration of oil accumulated on the paleostructure to Shiiya stage. (2) The local migration of oil are distinctly after Nishiyama stage and petroleum (or gas) finaly was trapped in the structure according to the structural movement after Uonuma stage.

Rivers characterized by suspended load and bed load tend to build fine-grained deltas and coarse-grained deltas, respectively. Gilbert-type deltas consisting of topset, foreset, and bottomset beds are recognized in marine environments as well as in lakes. Coarse-grained deltas tend to be Gilbert-type deltas. However, fine-grained deltas built in deep-water rivermouths and in wave-dominated rivermouths are mostly Gilbert-type deltas.Bird foot, lobate, cuspate, and estuarine deltas are recognized in marine environments. In contrast, estuarine deltas do not occur in lakes, since lakes are less subjected to tidal influences than seas.

The characteristics of petroleum exploration are discussed here with historical sense and schematic view, in order to understand scientific and technological nature of exploration. On the basis of such understandings, this paper discusses how modern explorationists can seek a clue of new technological development, when they intend to know what to do promptly for the future successful and expandable exploration.First of all, they had better review remaining questionable points and re-examine unsolved problems in the past “normal exploration,” with having doubts about previous interpretations, and with their close and careful attention. Such actions should be just the studies called “extraordinary exploration,” and those may be a trigger to lead important logic creation to be called “exploration revolution.”As the second action, unconventional exploration must be conducted with wide variety. The exploration of so-called unconventional type of resources such as natural gas hydrates or hydrocarbon from tight reservoirs and so on may not be based yet upon a completed scientific theory. Process to construct new theory replacing or standing in a line to the ongoing paradigm of petroleum exploration, however, may be the action that is appropriate to be described an “exploration revolution.”The third of what the explorationists should do is to conduct “normal exploration” itself continuously. The expansion of the objectives of conventional exploration is a driving force to pull innovation in the technology of drilling and production, and leading factor of maturity of exploration. Maturation of normal exploration with a recent paradigm will encourage an outbreak of following exploration revolutions through the occurrence of extraordinary explorations.

Current situation and future possibility of the K-Ar and 40Ar/39Ar dating methods are reviewed focusing their utilization to the Tertiary volcanic rocks. As Tertiary volcanic rocks in general are not completely free from weathering and alteration, special attention should be made in choosing appropriate samples for age analyses. K-Ar and 40Ar/39Ar analytical results are shown for two contemporaneous rocks of Middle Miocene age, one is a porphyritic intrusive rock with holocrystalline groundmass and the other is an extrusive lava with glassy groundmass. The former gives concordant K-Ar and 40Ar/39Ar ages, while the latter shows considerably younger K-Ar and 40Ar/39Ar total gas ages with the obviously disturbed 40Ar/39Ar age spectra in the low temperature fractions. These results suggest that holocrystalline rocks are preferable to glassy rocks in K-Ar and 40Ar/39Ar dating, because glass tends to easily loose the accumulated radiogenic 40Ar not only by decomposition but also by hydration. Accurate and precise age determinations can be achieved by the 40Ar/39Ar incremental heating experiments along with the age spectrum and isochron interpretations. Total fusion 40Ar/39Ar dating for single to a few grains of fresh K-bearing phenocrysts like biotite, sanidine and plagioclase is also useful in knowing the ages for glassy and/or altered rocks. Multiple analyses on such mineral separates ensure the reproducibility of the analyses and reduce the analytical uncertainty by statistical treatments. Systematic 40Ar/39Ar studies are now underway to construct the accurate and precise tectonic history of the Japanese island arc.

Teikoku Oil Co., Ltd. (TOC) completed Shizuoka-line (Koufu to Gotenba-City, 81km) at the end of 2006. Also, Shizuoka Gas Co., Ltd. (SZG), Tokyo Gas Co., Ltd. and TOC completed the Minamifuji-pipeline (Gotenba to Fuji-City, 31km) at that time. Those pipelines are in series and, with those completion, natural gas pipeline system between the Japan Sea and the Pacific Ocean was realized connecting with the Minami-nagaoka natural gas field (also with the Sekihara underground gas storage) in Niigata prefecture and the Sodeshi LNG receiving terminal of SZG in Shizuoka prefecture. Since domestic gas and imported gas (LNG) can be fed into the pipeline system, it is strongly expected that gas supply in the eastern area of Honshu Island becomes more flexible and reliable.

The firework industry in Niigata Prefecture is famous, and the firework makers in Niigata and a few other prefectures satisfy greater part of the domestic demand in fireworks. Especially, the Japanese largest firework, so called “Yonshaku dama” which is approximately 120 centimeters in diameter, can be produced and launched only by Niigata's firework technology.Gunpowder was historically introduced to Japan with gun technology in 1543. Since gun armament was prohibited by Tokugawa government in the Edo period, gunpowder makers had to resign their posts and some have supposed to become firework artisans. “Kagiya” as the first firework maker in the Edo City, have opened a store in 1659. Skyrocket-type modern fireworks were invented about 100 years after then. The Japanese skyrocket-type fireworks, well known as “Japanese Style Firework” in the world, have spherical outside appearance, and it open spherically once launched to the sky, in contrast to cylindrical shape of European fireworks.Firework technology seemed to have been transmitted from the Kansai district not only to the Edo City, but also to some rice field basins of large rivers flowing into the Sea of Japan in the Northeast Japan, such as Katakai Town, perhaps related to “Kitamae” cargo boat services.

LNG has been the major oversea transportation means since the era of 1970. The development costs of LNG plant, export and import terminals and LNG carriers have been very expensive, then only huge gas fields more than several Tcf reserves have been developed which enables initial cost recovery. Technical innovation, clean energy demand and the current oil price ascent are leading the stranded gas fields development by use of new gas transportation technology. Among them CNG (compressed natural gas) is one of the means which has low energy loss in the CNG processing compared to chemical transformation such as GTL (gas to liquid) and is capable to supply gas directly to the gas pipeline grid by easily re-gasification on board CNG carrier. This paper describes technical and economical characteristics of CNG and its application among many gas transportation systems.

The exploration well named METI Joetsu Kaikyu (JX) was drilled in the “Buri” structure in the Joetsu Basin from April through July, 2013. The “Buri” structure is located in the Joetsu Knoll at the eastern edge of the Sea of Japan, offshore Niigata Prefecture, Japan.This well reached down to 3,110mMDBRT and confirmed the Haizume, Nishiyama, Shiiya (Pliocene), Upper Teradomari (Upper Miocene) and Lower Teradomari (Upper Miocene) Formations. Those formations were mainly composed of interbedded sandstone and mudstone with minor tuff. Four key beds, “P tuff”, “Q tuff”, “S tuff” and the fossil marker of “Blue Zone” which are identified in the Niigata Basin were also recognized in this well.Several hydrocarbon shows were encountered in the target sections between the Shiiya and Lower Teradomari Formations. The methane gas shows were observed in the main part of the Shiiya Formation without any oil shows. Several minor oil and gas shows were encountered between the basal part of the Shiiya and Lower Teradomari Formations.Although the hydrocarbon accumulations have not been discovered, valuable subsurface information such as stratigraphy, geochemistry and rock properties has been acquired in the well, which contributes to a further understanding of the petroleum system and future hydrocarbon exploration in the Joetsu Basin.

INPEX Browse Ltd. has drilled 6 wells in the Browse Basin in order to appraise the production permit WA-285P from 2000 through 2004 (at the 1st and 2nd Drilling Campaign). All of wells have encountered stuck pipe problems while drilling the unconsolidated Grebe formation sandstone and they have provided a lot of Non Productive Time (NPT) due to fishing or sidetrack. According to the desk top study of Grebe, which was performed after drilling in 2004, it was concluded that the stuck pipe problems result from the collapse of unconsolidated sand, in other words, such collapse is caused by the absence of an effective filter cake capable of stabilizing the well bore. Eventually, INPEX Browse Ltd. has decided to drill the unconsolidated Grebe formation sandstone by closed circulation system using drilling mud instead of Seawater.<br>In order to achieve this objective, Riserless Mud Return (RMR) system was introduced by AGR (Norwegian Company) before 3rd Drilling Campaign. Through this system, all three (3) wells have been successfully drilled without any hole collapse and no NPT was recorded. That is a major improvement rather than last two (2) drilling campaign and RMR system was demonstrated as one of an effective procedure to drill unconsolidated formation in Browse Basin.

The eastern margin of the Japan Sea has rifted in the early Miocene. Then it hascompressed during the late Pliocene through the Quaternary. This change of stress caused basininversion along the margin, but the inversion structures vary mainly due to difference of therifting structures. In this paper, three types of basin inversion were defined. Type A basininversion is characterized by simple inversion of half grabens. Miocene normal faults reactivatedas reverse faults and the whole grabens have been uplifted. Many basin inversions of this typehave been widely formed in the Sado Ridge and Mogami Trough in the southern part of theeastern margin of the Japan Sea, to the west of the Tohoku Arc. Type B basin inversion isdefined by anticlinoriums in the major rift basins along the coastal zone of the Tohoku arc. Therifts have been partly uplifted by reverse faults and asymmetric anticlines, suggesting that partsof the extensional faults in the rifts have reactivated. Type C basin inversion forms the OkushiriRidge which continues in the N-S direction along the eastern margin of the Japan Basin to thewest of Hokkaido. It is not clear that the ridge has overprinted on the preexisting extensionalfaults. Reverse faults in the three types of basin inversion are accompanied by asymmetricanticlines or anticlinoriums. The profiles of the anticlines suggest that hinges of the anticlineshave been fixed during the growth of the anticlines. These structure and growth pattern of theanticlines can be explained by listric reverse faults and detachments at 10-20km in depth. Thegeologic structure related with extensional tectonics are generally obscure due to the lack ofpre-rift sedimentary sequences and extensive activity of volcanism in the rifting stage.Consequentry, it is difficult to clarify the relationship of the major fault systems between theextensional and compressional stages.

Activities by man-kind are limited in the Arctic, high latitude place more than North 66°33′, because of its hostile environment. Only military base, scientific observation station, resources production sites and ethnic community exist. Oil and gas E&P activities have been made in limited area such as Timan-Pechora area and Yamal peninsula in Russia, Mackenzie delta in Canada, North-Lope in Alaska and Barents Sea. Especially for offshore exploration activities in Arctic, it is highly affected by sea ice. As observed by satellite image in Arctic, no or less ice affected areas are defined such as Barents Sea and Norwegian Sea. Ice covered area in the Arctic and near of the Arctic requires serious counter measures against sea ice for putting oil and gas exploration into execution. In this lecture, recent oil and gas exploration activities in the ice covered Arctic offshore area are reviewed. In addition, history and challenge for future on new exploration license area in northeast offshore Greenland, where Greenland Petroleum Development Ltd. (GPX), Japanese Joint Venture Company established by JOGMEC, INPEX, JX, JAPEX and MOECO, are discussed. Although increase of exploration activities in Arctic is expected in the days to come, there are several technical challenges and difficulties for matter of environmental protection. It is an important mission for E&P companies to overcome those challenges and difficulties and to promote frontier oil and gas exploration in the Arctic area.

Deepwater area in the Southern Gulf of Mexico is one of the most attractive areas for future petroleum exploration. JOGMEC carried out a petroleum system evaluation study jointly with PEMEX-E&P in this region using existing wells and seismic data acquired by PEMEX-E&P. The study consists of 1) 1D thermal modeling at the well locations to obtain heat flow variation, 2) map-based modeling to identify effective kitchen areas and migration paths for the hydrocarbon generated in the source rocks, 3) tectonic restoration on the 2D seismic sections along the migration paths, and 4) 2D petroleum system modeling to understand hydrocarbon charge history in the study area. Due to complicated geology with salt intrusions and thrusts, conventional modeling workflow is not valid to fully reveal the hydrocarbon charge processes in the study area. In this paper, authors briefly introduce a suitable modeling workflow and the methodologies which we applied to the study.

The methylphenanthrene distributions of crude oils from oil and gas fields have been measured in the JAPEX Research Center as a part of the routine geochemical analysis since 2004. We have examined the validity of the two methylphenanthrene maturity parameters, the methylphenanthrene index 1 (MPI 1) and the methylphenanthrene ratio (MPR), for crude oils in Niigata Prefecture (the Niigata oils). The results are summarized as follows.1) The Niigata oils show a regular change with maturity on the MPI 1-MPR plot.2) The Niigata oils are divided into the following three maturation stages on the MPI 1-MPR plot.Stage 1 : oil generation stageStage 2 : condensate generation stageStage 3 : oil cracking stage3) The MPI 1-MPR plot is applicable to crude oils in the Akita and Hokkaido districts.4) This plot is useful for the estimation of relative maturity levels and the oil to oil correlation.

A pilot-scale CO2 sequestration test into an onshore saline aquifer has been conducted in Nagaoka-City, 200km north of Tokyo under cooperation of Research Institute of Innovative Technology for the Earth (RITE) and Engineering Advancement Association of Japan (ENAA).The aquifer, 1,100 meters in depth and 12 meters in thickness, is in shallower zone of Minami-Nagaoka gas field which is being operated by Teikoku Oil Co., Ltd. (TOC). An injection well and three observation ones were drilled in the site. CO2 of supercritical phase had been injected into a permeable zone in the aquifer with the rate of 20 to 40 tonnes per day. The injection started on July 7, 2003 and ended on January 11, 2005 with total amount of 10,405 tonnes. A series of monitoring method including time-lapse well logging, time-lapse cross-well seismic tomography, bottom-hole pressure/temperature measurement, fluid sampling and microseismicity monitoring have been successfully carried out to grasp the movement of injected CO2 during and after the injection. History-matching simulation had been performed to interpret the monitoring results. Long-term CO2 movement was predicted using the last model of history matching, implying the location and size of the CO2 to remain almost unchanged from those at the end of injection in the test area over a period as long as 1,000 years. The monitoring at the test site will be continued until 2007.
