Exploration And Production

Geological modelling is an important topic of oil and gas exploration and production. A new knowledge driven methodology of geological modelling is proposed to address the problem of “hard data” limitation and modelling efficiency of the conventional data driven methodology. Accordingly, a new geological modelling software (DMatlas) (V1.0, Dimue, Wuhan, China) has been developed adopting a grid-free, object-based methodology. Conceptual facies models can be created for various depositional environments (such as fluvial, delta and carbonates). The models can be built largely based on geologists’ understandings with “soft data” such as outcrops analysis and geological maps from public literatures. Basic structures (fault, folds, and discrete fracture network) can be easily constructed according to their main features. In this methodology, models can be shared and re-used by other modelers or projects. Large number of model templates help to improve the modelling work efficiency. To demonstrate the tool, two case studies of geological modelling with knowledge driven methodology are introduced: (1) Suizhong 36-1 field which is a delta depositional environment in Bohai basin, China; (2) a site of the north Oman fracture system. The case studies show the efficiency and reliability within the new methodology.

Regional aeromagnetic surveys of the interior Canning Basin, completed in 1964, showed a distinct pattern of deep sub-basins separated by relatively shallow platforms south of the Broome Platform. Seismic work on the margins of two of these basins-the Parda and Kidson Sub-basins--resulted in three drill sites. In 1965 WAPET drilled Sahara No. 1 in the Kidson Basin (suspended T.D. 6,956 feet in salt); Parda No. I near the southern margin of the Broome Platform (T.D. 6,256 feet in Basement); and Willara No. 1 in the Parda Basin (T.D. 12,806 feet in Ordovician). This paper is a preliminary report of the section encountered in these three wells.No commercial quantities of oil or gas were encountered in the recent wells but they have added significantly to our knowledge of the South Canning. The three major contributions to our stratigraphic knowledge are:The Ordovician thickens from about 2,000 feet to over 6,500 feet basinward from the Broome Platform (Parda No. 1) southward to the Parda Basin (Willara No. 1). This demonstrates that the Parda Basin was a depositional basin (mainly shale) during the Ordovician. An oil show was noted in the Goldwyer shale unit in Parda No. 1.A Redbed-Evaporite sequence with major amounts of rock salt occurs between the Middle Ordovician and the 1liddie Devonian. This sequence has not been previously encountered in the Canning Basin.The Sakmarian Grant Formation of the Lower Permian which is typically glacial and fluvioglacial includes an upper marine shaly member in two of the recent wells (Sahara No. 1 and Willara No. 1). It is suggested that an arm of the sea extended across large portions of the South Canning while adjacent areas were subjected to continental glaciation. A small hydrocarbon show was recorded in the Upper Grant in Willara No. 1.The significance of these drilling results to oil and gas exploration can be summarised as:A major Ordovician marine basin with rapid thickening and carbonate-shale facies changes in the South Canning presents attractive hydrocarbon prospects.The presence of widespread evaporites as an indicator of restricted marine conditions and as a seal to prevent the escape of hydrocarbons is a favourable factor.The presence of a marine shaly unit with porous sandstone beds in the Permian Grant Formation presents an additional shallow drilling target in the South Canning, especially in the light of the show encountered in Willara No. 1.

Properties of Energy Materials (oil and gas) is very complex and important. In recent years, in Chinese eastern, western and mid continental basins, multiple rock oil and gas fields are found, such as Songliao Basin, Bohai Bay Basin, Erlian Basin, Tuha Basin, Junggar Basin, Sichuan Basin. Volcanic rock reservoir with its rich oil and gas resources, tremendous development potential, has aroused the domestic and foreign experts and scholars attention, volcanic rock oil and gas exploration theory and technology has been rapid development. In order to understand volcanic rock reservoir from the origin, further exploration target and guide the exploration deployment, the Properties of Energy Materials (oil and gas), main factors affecting of the development and comprehensive evaluation have become the research hot spots and the focus, there are many research techniques and results.

In recent years, the natural gas has displayed a growing significance in oil and gas exploration in the northwestern Junggar Basin (NWJB), although oil has been the main focus of exploration in the basin. Here, we systematically discuss the classification and origin of the natural gases from the NWJB based on the natural gas geochemistry and chemometric methods. The natural gases collected from the NWJB were chemometrically classified into three groups. Group A gases, defined as coal-derived gases, were likely generated from the mixing of the Jiamuhe Formation and Carboniferous strata. Group B gases, defined as the mixing of coal-derived and oil-associated gases, were restricted to the source rocks of group A and C gases. Group C gases, defined as oil-associated gases, were likely derived from both the Fengcheng and Wuerhe Formations, with a higher contribution from the latter strata. The result of this study suggests that the potential of oil generation in the Wuerhe Formation has been underestimated in the past. This is in accordance with geochemical and geological evidence. This study provides an effective chemometric method of natural gas classification and evaluation of hydrocarbon generation potential. This contributes to a better understanding of the origin of gases and distribution of oil and gas, assisting in exploration deployment in the basin.

Oil And Gas Operations

Facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passion, they cannot alter the state of facts and evidence (Adams 1770). Some people unfamiliar with upstream petroleum operations, some enterprises keen to sustain uncontested land use, and some people against the use of fossil fuels have and will voice opposition to land access for oil and gas exploration and production. Social and economic concerns have also arisen with Australian domestic gas prices tending towards parity with netbacks from liquefied natural gas (LNG) exports. No doubt, natural gas, LNG and crude-oil prices will vary with local-to-international supply-side and demand-side competition. Hence, well run Australian oil and gas producers deploy stress-tested exploration, delineation and development budgets. With these challenges in mind, successive governments in South Australia have implemented leading-practice legislation, regulation, policies and programs to simultaneously gain and sustain trust with the public and investors with regard to land access for trustworthy oil and gas operations. South Australia’s most recent initiatives to foster reserve growth through welcomed investment in responsible oil and gas operations include the following: a Roundtable for Oil and Gas; evergreen answers to frequently asked questions, grouped retention licences that accelerate investment in the best of play trends; the Plan for ACcelerating Exploration (PACE) Gas Program; and the Oil and Gas Royalty Return Program. Intended and actual outcomes from these initiatives are addressed in this extended abstract.
