Pelaksanaan kegiatan operasional di area offshore pada perusahaan eksplorasi dan eksploitasi minyak dan gas bumi membutuhkan bahan bakar yang cukup banyak. Bahan bakar ini sebagian besar digunakan untuk mobilisasi berbagai jenis kapal sebagai fuel object dan operasional harian proses produksi. Terdapat beberapa kriteria umum yang menjadi dasar penjadwalan pengisian BBM, namun setiap koordinator berhak menyusun penjadwalan berdasarkan pengalaman dan subjektifitas masing-masing. Oleh karena itu jadwal yang disusun antar koordinator bisa sangat berbeda, agar memiliki standar yang seragam maka sangat diperlukan suatu metode yang terstruktur dengan kriteria standar dalam pengambilan keputusan penyusunan penjadwalan pengisian BBM. Penelitian ini bertujuan untuk mengetahui kriteria apa saja yang menjadi dasar pertimbangan dalam penjadwalan pengisian BBM dan mengembangkan suatu sistem agar keputusan penjadwalan yang diambil bisa terukur dan dipertanggungjawabkan dengan baik. Metode yang digunakan pada penelitian ini adalah rating approach Analytical Hierarchy Process (AHP), sedangkan pengelompokan kapal (klaster) yang akan diisi menggunakan metode hierarki agglomerative, complete linkage dengan euclidean distance. Hasil dari penelitian ini menunjukkan bahwa area kerja akan dibagi menjadi 3 klaster dengan jumlah SPOB sebanyak 3.  Selanjutnya kriteria yang dijadikan dasar pertimbangan dalam pengambilan keputusan penjadwalan pengisian BBM adalah  fuel remaining day fuel object, prioritas operasi, akses menuju fuel object dan jarak SPOB dengan fuel object. Berdasarkan analisis implementasinya, metode penjadwalan dengan menggunakan rating approach AHP dapat memberikan jadwal yang konsisten, terukur,bisa dipertanggungjawabkan, dan sangat mudah diimplementasikan serta dapat menghindari terjadinya perbedaan penjadwalan (subjektivitas) antar koordinator.        Abstract[Fuel Distribution Scheduling For Self Propelled Oil Barge (SPOB) Based On The Hierarchy Process Analityc Method] The implementation of operational activities in the offshore area of oil and gas exploration and exploitation companies requires quite a lot of fuel. This fuel is mostly used for the mobilization of various types of ships as a fuel object and for the daily operations of the production process. There are several general criteria that form the basis for scheduling refueling, but each coordinator has the right to arrange a schedule based on their own experience and subjectivity. Therefore, the schedule prepared between the coordinators can be very different, in order to have a uniform standard, it is necessary to have a structured method with standard criteria in making decisions on the preparation of fuel filling scheduling. This study aims to find out what criteria are the basic considerations in scheduling refueling and develop a system so that scheduling decisions taken can be measured and accounted for properly. The method used in this study is the rating approach Analytical Hierarchy Process (AHP), while the grouping of ships (clusters) to be filled using the agglomerative hierarchy method, complete linkage with euclidean distance. The results of this study indicate that the work area will be divided into 3 clusters with the number of SPOB as much as 3. Furthermore, the criteria that are used as the basis for consideration in making decisions about fuel filling scheduling are fuel remaining day fuel object, operating priority, access to fuel object and distance between SPOB and fuel. objects. Based on the implementation analysis, the scheduling method using the AHP rating approach can provide a schedule that is consistent, measurable, accountable, and very easy to implement and can avoid scheduling differences (subjectivity) between coordinators.Keywords: Analytical Hierarchy Process; Fuel Object; Scheduling; SPOB

The paper formulates a new vision of the reasons for the formation of the modern structural-geological appearance of the Northern Black Sea and the offshore area of the Azov Sea. The catastrophic events in the Northern Black Sea, during the Permian-Triassic period, about 250 million years ago, allegedly occurred. Giant asteroid exploded (or just collapsed) when it entered the dense layers of the atmosphere, and its multifarious debris formed numerous circular structures on the Northern Black Sea during the fall. It has suggested that this space catastrophe is the forerunner of the famous Permian extinction of the terrestrial biota.  Graphically and descriptively, it has been proved that approximately along the Bataisk-Krasnoperekopsk-Izmail line, according to the RSD, 3 large circular structures and up to 20 small ones are decoded. It is proved – the line corresponds to the Northern suture zone, which separates the East-European platform from the Scythian epiorogenic zone. The suture area has been active for approximately 250 million years. It has been theoretically proved that it is the invasive effect of the cosmic body that is the root cause of the fault zone, which in Cimmeria evolved into the Northern suture zone. Using modern RSD made it possible to identify large circular structures of the Northern Black Sea Region. These are Azov, Bataisk and Kalamitska. Major research interest in the segments of the Azov astrobleme in the context of the oil and gas exploration work is determined. It is proved by retrospective geological information that the identifying structures have a significant depth of occurrence and here the earth’s crust should be saturated with a significant number of supply channels (decompression zones) favorable for hydrocarbon migration.

Considering the pollution on the environment using dynamite source in oil and gas exploration, harm and damage to people and building, the vehicle mounted hammer source which can replace dynamite source is presented. This paper describes briefly the basic structure and working principles of the vehicle mounted hammer source. A typical pneumatic circuit is researched and designed. And the pneumatic circuit is designed with the powerful functions of PLC, the hardware and software design are introduced. The system has advantages of strong striking force, high velocity, small gas consumption, simple structure and convenient control.

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.
