Along with conventional methods, this paper proposed a method in which 1 D and 3 D models are integrated to identify the self-sourced reservoir potential of the Farewell Formation in the Kupe Gas Field within the Taranaki Basin, New Zealand. Source rock characteristics were evaluated at both field and basin scales by investigating source rock maturity, type of organic matter,and hydrocarbon generation potential by rock pyrolysis,using Rock-Eval 2 and 6. The 1 D thermal and burial history model established the rate of sedimentation and thermal history of the Kupe 4 well. Reservoir characterization at field-scale was determined by seismic interpretation, well log analysis, and 3 D structural and petrophysical models. The sediments of the Farewell Formation contain types II-III（oil/gas prone） and type III（gas prone） and have fair-to-excellent generation potential. The oxygen and hydrogen indices ranged from 3 to 476 mg CO2/g TOC and 26 to 356 mg HC/g TOC, respectively, whereas the thermal maturity determined by vitrinite reflectance values ranged between 0.3% and 0.72%, indicating that the Farewell Formation is in immature-to-mature hydrocarbon generation stage. Thus, Farewell Formation was verified to be a good source rock. Additionally, structural interpretations demonstrated the structural complexity of an extensional and contractional regime within the reservoir package. Multiple faults indicated a good reservoir property there with a trapping mechanism as well as migration paths. A well-log-based petrophysical analysis established the presence of up to 70% hydrocarbon saturation within the pore spaces of Farewell *** 3 D models confirmed that the Farewell Formation has significant sand zones and hydrocarbon-saturated zones,thereby proving its very good reservoir characteristics. It has been proved that the 1 D and 3 D structural schemes,integrated with geological techniques, was vital in identifying the Kupe Field as a self-sourced reservoir.

利用三维地震和测井资料对Maui气田晚白垩世—上新世的沉积层序建立构造模型，结合地质统计学方法预测Taranaki盆地的构造力学特征。通过构造模型识别出受断裂影响的3期构造运动：晚白垩世—古新世裂谷期、晚始新世—中新世挤压性断裂期、上新世一更新世构造分化期（Maui气田南部挤压性断裂、Maui气田北部正断层活动）。各期构造运动形成不同的构造样式，早渐新世以前具有轻微走滑特征的正断层较发育，断层倾角大（40°-70°），北部地层倾角（10°-15°）低于南部（15°-20°）；中渐新世一晚中新世发育低角度逆断层（20°-40°），表明这一时期构造整体受到挤压性应力作用；中渐新世—上新世地层出现构造反转，表明这一时期构造应力为先挤压后拉张。

引用

Occupational Diseases and Environmental Medicine 2018年第1期6卷 1-22页

作者： Wafaa Ibrahim Soliman Nashwa mohamad mohamad shalaby Hisham Mohammed Al-sayed Mona Hamed Ibrahim Department of Forensic Medicine and Clinical Toxicology Faculty of Medicine Zagazig University Zagazig Egypt Department of Neuropsychiatric Faculty of Medicine Benha University Benha Egypt Department of Community Environmental and Occupational Medicine Faculty of Medicine Zagazig University Zagazig Egypt

Background: The central nervous system is one of the most important systems affected by formaldehyde (FA). Aim of Work: This study was designed to assess its toxic neuropsychiatric effects both clinically and experimentally and the protective effects of garlic. Methods: Clinically: 20 workers in the gross anatomy laboratory and 20 libertarians underwent a standardized clinical assessment including medical, neurological and psychiatric examination. Experimental: 40 male rats were divided randomly into four groups. Group I is control group. Group II received 10 mg/kg of FA intraperitoneally once daily for 14 days. Group III was treated with fresh garlic juice (1 ml/100g body weight) once daily by oral gavage for 14 days. Groups VI received fresh garlic juice plus formaldehyde daily for 14 days. At the end of the experiment, the rats’ brains were obtained for histological examination and biochemical analysis. Results: Clinical and psychiatric profile of FA exposed persons’ revealed cognitive impaired, anxious and depressed persons. There were hostile persons with more hostility toward outside. Experimentally, hippocampal and frontal superoxide dismutase and reduced glutathione showed highly significant decrease while malondialdehyde and nitric oxide level showed highly significant increase in formaldehyde treated group when compared with control group. Also histopathological changes in the hippocampal and frontal cortices by light microscope revealed many distorted cells with deeply stained shrunked nuclei and cytoplasm was surrounded by vacuolated pale areas in FA exposed group. Minimization of biochemical and histopathological changes were observed in combined formaldehyde and garlic treated group. Conclusion: The profiles of personality arouse dangerous affairs about the toxic impact of FA on persons, family, and society. Formaldehyde-induced neuronal damage, oxidative stress and lipid peroxidation in brain were minimized by addition of garlic.
