New Zealand's scientific institutions have been restructured so as to be more responsive to the needs of the economy. Exploration for and development of oil and gas resources depend heavily on the geological sciences. In New Zealand, these activities are favoured by a comprehensive, open-file database of the results of previous work, and by a historically publicly funded, in-depth knowledge base of the extensive sedimentary basins. This expertise is now only partially funded by government research contracts, and increasingly undertakes contract work in a range of scientific services to the upstream petroleum sector, both in New Zealand and overseas. By aligning government-funded research programmes with the industry's knowledge needs, there is maximum advantage in improving the understanding of the occurrence of oil and gas resources. A Crown Research Institute can serve as an interface between advances in fundamental geological sciences, and the practical needs of the industry. Current publicly funded programmes of the Institute of Geological and Nuclear Sciences include a series of regional basin studies, nearing completion; and multi-disciplinary team studies related to the various elements of the petroleum systems of New Zealand: source rocks and their maturation, migration and entrapment as a function of basin structure and tectonics, and the distribution and configuration of reservoir systems.

It is shown that the evolutionary-catagenetic model for calculating the initial potential hydrocarbon resources can serve as a scientific basis for the separate quantitative prediction of areas of oil-and-gas content. In this case retrospectively evaluated are the scales of generation and accumulation of hydrocarbons in the source rocks during catagenetic evolution of sedimentary basin. The authors propose a method, the results of evaluation of generation and accumulation scales and initial potential oil and gas resources for major oil-and-gas bearing complexes of Dzhebol stage.

The World

The Proterozoic–Lower Paleozoic marine facies successions are developed in more than 20 basins with low exploration degree in the world. Some large-scale carbonate oil and gas fields have been found in the oldest succession in the Tarim Basin, Ordos Basin, Sichuan Basin, Permian Basin, Williston Basin, Michigan Basin, East Siberia Basin, and the Oman Basin. In order to reveal the hydrocarbon enrichment roles in the oldest succession, basin formation and evolution, hydrocarbon accumulation elements, and processes in the eight major basins are studied comparatively. The Williston Basin and Michigan Basin remained as stable cratonic basins after formation in the early Paleozoic, while the others developed into superimposed basins undergone multistage tectonic movements. The eight basins were mainly carbonate deposits in the Proterozoic–early Paleozoic having different sizes, frequent uplift, and subsidence leading to several regional unconformities. The main source rock is shale with total organic carbon content of generally greater than 1% and type I/II organic matters. Various types of reservoirs, such as karst reservoir, dolomite reservoir, reef-beach body reservoirs are developed. The reservoir spaces are mainly intergranular pore, intercrystalline pore, dissolved pore, and fracture. The reservoirs are highly heterogeneous with physical property changing greatly and consist mainly of gypsum-salt and shale cap rocks. The trap types can be divided into structural, stratigraphic, lithological, and complex types. The oil and gas reservoir types are classified according to trap types where the structural reservoirs are mostly developed. Many sets of source rocks are developed in these basins and experienced multistage hydrocarbon generation and expulsion processes. In different basins, the hydrocarbon accumulation processes are different and can be classified into two types, one is the process through multistage hydrocarbon accumulation with multistage adjustment and the other is the process through early hydrocarbon accumulation and late preservation.

Background. Decline of oil and gas traditional reserves pushes companies to explore and involve in production complex reservoirs which results in exploration risks increase. That is why an exploration research has to be integrational and its’ main result has to be determination and decreasing uncertainties. Aim. The aim of this research is the planning of further exploration program within the studied territory, based on the main uncertainties and trends in geological development. Materials and methods. Several types of research methods were applied, including field observation, laboratory analysis and geological desktop studies. The results of petroleum systems modeling is the basis for source rocks maturity prediction, the main stages of hydrocarbons generation — migration and critical moment estimation. It also provided the analysis of migration distance (limits) and geological risks related to it, petroleum saturation prediction for the main plays. Great emphasis was also placed on the search and processing of additional archival data, which made it possible to significantly detail the structural-tectonic framework of the studied area. Results. Consistent progression in field observation, laboratory analysis and geological desktop studies allowed to narrow the range of uncertainties, clarify the chance of geological success (gCOS), plan the further exploration program, and highlight higher-priority license blocks. As a result, more than 60 additional prospects were identified, for each of them both the probabilistic estimation of oil and gas resources and chance of geological success evaluation were made. Moreover, the further exploration program was approved. Conclusions. Therefore, the study allowed to analyse main uncertainties and correct further exploration program on the basis of integrated analysis of geological development history and geological structure of the studied area.

Continental shelf is a relatively new concept in international law of the sea. Full authority and exclusive rights over natural resources located in the continental shelf region and its ownership is on the coastal state, where the meaning of this natural wealth is a source of minerals and other lifeless on the seabed and subsoil. Through the establishment of the United Nations Convention on the Law of the Sea 1982, as well as enactment of the provisions of the New Law of the Sea, Indonesia is an archipelagic state which is seen as a unified whole between the islands and waters. We realized the sea was rich in minerals mining goods that is priceless natural resources, which is expected to be able to fulfill the needs of the world if mineral resources on land are not sufficient or run out completely. In Indonesia, mostly consisting of ocean territory, surely have the very wide continental shelf, where there is a variety of natural resources, especially oil and gas resources. Hence it needs regulation for the natural resources utilization in the region.Keywords :  Continental Shelf, Natural Resources, Seabed and Subsoil.

Abstract The Middle East contains some of the most fascinating and prolific oil provinces in the world. The combination of excellent source rocks of different geologic ages, the presence of outstanding reservoirs and ubiquitous seals, optimal thermal history, and structural evolution provides an ideal recipe to produce the largest oilfields in the world. The UAE is currently estimated to hold 6% of global oil reserves, 96% of which are within Abu Dhabi. However, exploration for additional recoverable reserves is becoming more challenging. Finding hydrocarbons for the future is dependent upon a detailed understanding of the petroleum systems and subtle play types. For southeastern Abu Dhabi, several petroleum systems have been proposed to explain the oil and gas accumulations in Lower Cretaceous reservoirs. This study presents the practical application of a geochemical inversion workflow to a set of oil samples from Lower Cretaceous reservoirs collected in two exploration wells recently drilled in southeastern Abu Dhabi. The geochemical inversion workflow is based on stable isotope, biomarker, and oil composition data. Preliminary results and comparisons with previously identified oil families in the UAE suggest that the oils were generated from a carbonate-rich source rock deposited during Jurassic time. Compositional data and detailed stratigraphic and structural analyses support the possibility of multiple episodes of lateral and vertical migrations. The implications and risk associated with the timing of oil generation and trap formation are presented here to define a path forward and guide the prospecting efforts within this exciting region.
