Safety And Environment

The development of new deepwater oil and gas fields provide an opportunity for increased use of new materials. Conventional infrastructure is constructed using significant quantities of steel and concrete, which is becoming less practical in comparison to new light weight, easy to handle composites. When infrastructure needs to be repaired, there is often a requirement for underwater welding, which carries considerable occupational health, safety and environment (OHSE) risks. For this reason, moving away from traditional metal structures or repair technologies is increasingly attractive. In recent years a number of new water activated composite wrap materials have been developed for use in underwater applications. The materials properties that are required can be difficult to achieve and maintain over an extended period of exposure to the marine environment, though, so many research groups are working on this challenge. A comprehensive literature review has been undertaken to identify present state of the art ideas for the development of improved underwater materials and this will be discussed in the context of adhesive applications. Preliminary material characterisation work will be described where new resins have been formulated to perform well in marine environments and survive prolonged exposure to seawater. Experiments were carried out in artificial seawater and samples left to cure at a range of temperatures DSC and dynamic mechanical analysis (DMTA) were used to evaluate the crosslink density of the network and the glass transition temperature respectively, while FTIR was used to determine the chemical structure in the cured systems. Preliminary mechanical test results have shown significant improvement in strength for the new formulations compared to a set of control samples of commercially available materials.

Offshore Oil

Subsea production systems have been an accepted method of developing offshore oil and gas fields since the installation of the first subsea trees in the early 1960s offshore California. Generally subsea completions have been done from floating drilling vessels on wells with subsea wellhead equipment. A number of wells have been completed subsea by bottom supported jackup rigs on wells drilled using mudline suspension equipment. The subsea completion equipment and methods utilised to adapt mudline suspension wells for a subsea production tree are described. This method of completion offers important benefits as it allows completion of wildcat or delineation wells, it can be used in areas of small, scattered reservoirs, and it can be used in conjunction with floating production systems. The cost associated with these subsea completions is roughly equivalent to those of standard subsea completions from floating vessels. An overview of a typical completion system is presented and compared.

Kajian geologi migas di Cekungan Tarakan relatif sangat kurang dibandingkan dengan Cekungan Kutai, diantaranya mengenai analisis stratigrafi sekuen yang lebih detil dan komprehensif, tingkat variasi lapisan sedimen di daerah transisi dengan laut dangkal sampai sedang dan keterkaitan dengan penentuan potensi migas. Padahal eksplorasi minyak dan gas bumi di Cekungan Tarakan, Kalimantan Timur telah mengalami proses waktu yang sangat panjang bahkan termasuk salah satu eksplorasi tertua di Indonesia. Namun eksplorasi di wilayah lepas pantai termasuk di timur Pulau Tarakan masih belum ditemukan lapangan migas yang bernilai ekonomis. Ini sangat berbeda dengan hasil eksplorasi Cekungan Kutai di lepas pantai dan laut-dalam yang telah mengalami kemajuan signifikan dalam 10 tahun terakhir setelah ditemukan beberapa lapangan migas laut-dalam seperti West Seno dan Gendalo. Berdasarkan pada pemerolehan data yang terdiri dari penampang seismik 2D, log sumur, rangkuman data biostratigrafi dan data check-shot, kajian dilakukan secara bertahap mulai dari analisis sekuen dan korelasi log sumur, interpretasi dan analisis seismik stratigrafi, pemetaan bawah permukaan, dan penentuan lokasi yang berpotensi migas. Tahapan metodologi kajian ini menggunakan beberapa perangkat lunak yang diproses secara integratif. Hasil akhir kajian dari integrasi peta struktur kedalaman dan peta isopach serta dukungan data petrofisik dari aspek kualitas batuan reservoir diperoleh dua lokasi yang berpotensi migas: Potensi Migas-1 di bagian tenggara dekat Pulau Tarakan merupakan jebakan struktur antiklin yang dikontrol sesar-sesar inversi dan Potensi Migas-2 di lepas pantai bagian timur wilayah kajian berupa jebakan struktur hidrokarbon sebagai sebuah antiklin yang memanjang relatif arah SEE â€“ NWW. Kata kunci: Tarakan, sekuen, seismik, potensi migas Study of Petroleum geology in the Tarakan Basin is relatively less than in the Kutai Basin such as detailed and comprehensively sequence stratigraphy, variation of sediment layering from transition to outer-neritic zone and its related to determination of oil and gas potential locations. Oil and gas exploration in Tarakan Basin, East Kalimantan, has been carried out for the last a hundred years ago and its include as the oldest basin in Indonesia. Unfortunately, oil and gas field in eastern part of offshore Tarakan Island has not yet been discovered significantly. In contrast, offshore and deep-water oil and gas fields of Kutai Basin has been discovered significantly i.e. West Seno and Gendalo Fields. Based on data of 2D seismic in SEGY-files, well log in LAS-file, biostratigraphy and check-shot data, then steps of research followed by a sequence analysis, wells correlation, interpretation and analysis of seismic stratigraphy, subsurface mapping and determination of oil and gas potential locations. The results of this study are oil and gas potency 1 and potency 2. Potency 1 is located in south-eastern part of Tarakan Island where anticlinal traps are controlled by inversion faults. In contrast, potency 2 is an anticlinal trap located in offshore at the eastern part of the study area. Key words: Tarakan, sequence, seismic, oil and gas potential

Remote Sensing Methods

In connection with the need to increase the energy resources of Ukraine, it is essential to expand the areas and depths of prospecting, as well as to improve the methodology and technology of oil and gas exploration. The most promising area for the search for new oil and gas fields in Ukraine remains the Pripyat-Dneprovsko-Donetsk oil and gas province. Increasing the depth of new energy sources because of the increasing cost of exploration and deep drilling requires more accurate and efficient predictions, which should be based on a more rigorous scientific substantiation of new directions of work and the application of new efficient technologies. The article develops the concept of deep degassing of the Earth, which is of great importance for the development of modern ideas about the formation and geological history of the Pripyat-Dnieper-Donetsk oil and gas province. The authors considered the nature of oil and gas accumulation areas and their relationship with the “pipes” of deep degassing of the Earth, as well as the possibilities of structural-tectonic, lithological-geochemical and remote sensing methods in identifying new oil and gas fields in the Pripyat-Dnieper-Donetsk oil and gas province and signs of their connection with «pipes» hydrocarbon deep degassing of the Earth. To implement new methodology and technology of prospecting, exploration of oil and gas fields, the article proposes to make wider use of the modern capabilities of satellite methods, which make it possible to quickly cover large areas with multiple surveys, increase the efficiency of solving geological problems, and also significantly reduce the cost of oil and gas exploration.

Abstract The Lower Kutei Basin which contains several giant oil and gas fields is located on the East Kalimantan, Indonesia. This paper discusses the identification and mapping of oil-filled reservoirs and their depositional facies by integrating seismic stratigraphy, attributes, and AI (Acoustic Impedance) inversion methods. The log data cross-plots show that AI can be used to distinguish oil-sands from wet sands and shale, and to derive the total porosity of the sands. However, AI and amplitude values are greatly affected by the oil, porosity and tuning effects, hence they cannot be used to identify the facies containing the oil-bearing sands. Therefore, to map the facies containing the oil-filled sands, the AI map is combined with the variance and sweetness maps. It can be seen clearly from the variance and sweetness maps that the oil-sands suggested by the AI map are contained in a narrow and elongate meander-like geometry which is typical of channel facies. The variance and sweetness maps suggest that there are two channels in the study area. To determine which channel is thicker, spectral decomposition RGB map was made. The result suggests that the right channel is more prospective as it associates with thicker sand deposits. The combination of variance, sweetness and RGB maps strongly indicate that the channels in the study area are in upper-slope environment, and the thicker oil-sands are located in the eastward of the study area.
