Nearly 30 years ago as the Soviet Union lay in tatters, Azerbaijan and Kazakhstan signed off on the Caspian’s first oil and gas megaprojects, hoping to guarantee their independence by transforming the region’s energy landscape and their role in it. Nursultan Nazarbayev, then president of Kazakhstan, took the first step in April 1993 by creating Tengizchevroil (TCO), a joint venture between Chevron and Kazakh state oil company KazMunaiGaz, to develop the super-giant Tengiz oil field and nearby Korolev field. Today, Chevron still holds 50% of the venture, ExxonMobil controls 25%, KazMunaiGaz, 20%, and LukArco, a subsidiary of Russia’s Lukoil, 5%. A year and a half later, in September 1994, Azerbaijan’s president, the late Heydar Aliyev, signed a production-sharing agreement (PSA) to develop the deepwater reserves of the Azeri, Chirag, and Gunashli (ACG) fields, attracting the participation of a “who’s who” of the world’s oil and gas elite—13 global companies representing eight countries. These and other signings had a knock-on effect as more upstream megaprojects popped up across the region in the late 1990s and throughout the early 2000s, attracting more international participation and the need to develop midstream infrastructure such as Azerbaijan’s Baku-Tbilisi-Ceyhan pipeline (BTC) export line to Turkey and Kazakhstan’s Caspian Pipeline Consortium (CPC) to Russia’s oil export terminal at Novorossiysk, as landlocked Central Asia devised ways to get its crude oil to market. For a generation, the Caspian’s top-heavy “bigger is better” way of doing things, led by global majors, did a good job of attracting upstream investment. But what about the next generation as those same supermajors rebrand and shift their portfolios to produce more energy with less carbon? Ashley Sherman, research director at Wood Mackenzie for upstream oil and gas, predicted in June that Caspian oil and gas production will continue to grow in this decade as already-committed oil and gas investments percolate through the system (Fig. 1). These investments, however, target expansion and optimization of existing operations. Thus, by 2030, upstream capital expenditures are likely to be at only half of their 2019 levels, Sherman wrote. BP and Socar’s (the state oil company of the Azerbaijan Republic) deepwater Shafag Asiman discovery in Azerbaijan may be an exception, but while a first exploration well drilled and completed in March detected gas condensate, the well was suspended pending further evaluation and possible drilling of a sidetrack appraisal well, BP said in a news release. The block lies 125 km (78 miles) southeast of Baku in an unexplored area in 650-to-800 m water depths. It is likely that tomorrow’s Caspian upstream will look a lot like today’s Caspian upstream, which is dominated by five projects: the onshore Tengizchevroil and Karachaganak projects in Kazakhstan; shallow-water offshore Kashagan, also in Kazakhstan; and Azerbaijan’s offshore deepwater ACG and the Shah Deniz gas field. While each of these projects elicits a definite “wow” factor in terms of sheer size, it is worth noting that the PSAs on which most of the projects are based will expire in the 2030s, though some remain in effect into the 2040s.

Environmentally safe oil and gas production demands permanent control for the development of ecological situation which should be managed on the basis of existing nature protection requirements and corresponding instruction documents. Purpose of the research and formulation of the problem is to select landscape complexes at the hierarchical levels of locations and facies in the Bykiv oil and gas field to make landscape map with morphological genetic and age features of landscape structure as the basis of environmental assessment of oil and gas field impact on the natural geosystems. Presentation of the main research material with full justification of the received scientific results. Landscape analysis of the investigated area allowed to select, ground and make mapping the following landscape complexes: landscape localities, foothill landscape complexes. Characteristic feature of the Bytkiv oil and gas field and neighborhoods is their high-altitude stratification from middle and lowmountainous to foothills and lowlands. The genesis or origin of the area under study is various - from denudation relics of the top peneplenization surface of leveling much younger pedyplenization surface pediments on the transition from mountainous to foothill relief, to deeply portioned erosionally active steep slopes and stairstepping of the river terraces. Age boundaries of the created landscape structures were determined on the availability of adjoint sedimentary formations from the producents of bedrock destruction, resedimented eolivan, deluvial, proluvial and alluvial processes.

The paper reviews the formation prospects of two up-to-date forms of economic cooperation in the sphere of oil and gas production – outsourcing and clustering, as well as the schematic presentation of their implementation. The outsourcing means the execution of the functions on the systematic professional support of working efficiency of the business customer by the operation company under the permanent contract. The outsourcing allows the oil-gas producing company increasing its capitalization and profit amount. Therefore, the oil company can fix innovative, scientific and technological resources in its hands providing maximum meeting of business customers’ demands. The development of oil service cluster, in its turn, aims to provide the interaction of all corporate parties. The establishment of cluster unions in oil-gas field with the participation of petroleum service companies under the principles mentioned in the paper will contribute to the development of both oil-gas complex in a whole and petroleum service market.

Abstract Halite scaling has been observed in the oil/gas field with high TDS and low water cut. Due to its higher solubility, slight changes in temperature (T) and pressure (P) and evaporative effect could yield a large amount of scale, causing significant operational problems. Accurate prediction and control of halite scaling in the oil and gas production system have been a challenge. Therefore, this study aims to shed light on the prediction of halite scale formation, deposition behavior, and inhibition at close to oil field conditions. We have designed and developed a dynamic scale loop (DSL) test methodology that can be used at various T and P. The test method utilizes a change in temperature (ΔT) as a driving force to create halite supersaturation and follow with the scale precipitation/deposition. The tube blocking experiments suggest that the tube blockage can be caused by bulk precipitation and or deposition of halite precipitate. SEM analysis of the tube cross-sections indicated that tube blockage, presumably by bulk precipitation, could be seen at the beginning of the reaction tube, but deposition was observed towards the exit end of the tube. Similarly, various experimentation to simulate the water dilution at constant pressure and ΔT were conducted. The effect of the addition of water to prevent halite deposition was analyzed computationally by using ScaleSoftPitzer (SSP) software. Brine compatibility of several inhibitors were tested via bottle tests and autoclave tests and qualified inhibitors were tested in the tube blocking experiments to identify the performance of the inhibitor to treat the halite precipitation at high temperature and pressure. Overall, a robust test method was designed and developed for halite scaling under high temperature and pressure that can simulate the oil and gas production in the field.

ABSTRACTWith much fanfare, Ghana's Jubilee Oil Field was discovered in 2007 and began producing oil in 2010. In the six coastal districts nearest the offshore fields, expectations of oil-backed development have been raised. However, there is growing concern over what locals perceive to be negative impacts of oil and gas production. Based on field research conducted in 2010 and 2015 in the same communities in each district, this paper presents a longitudinal study of the impacts (real and perceived) of oil and gas production in Ghana. With few identifiable benefits beyond corporate social responsibility projects often disconnected from local development priorities, communities are growing angrier at their loss of livelihoods, increased social ills and dispossession from land and ocean. Assuming that others must be benefiting from the petroleum resources being extracted near their communities, there is growing frustration. High expectations, real and perceived grievances, and increasing social fragmentation threaten to lead to conflict and underdevelopment.

Kerak pemendapan merupakan satu daripada masalah paling penting dan serius dalam sistem suntikan air. Kerak kadangkala mengehadkan atau menghalang penghasilan gas dan minyak melalui penyumbatan matrik atau perpecahan pembentukan minyak dan jeda yang berlubang. Makalah ini mengetengahkan kesimpulan pengukuran makmal bagi kerak terbentuk di dalam keterlarutan medan minyak biasa dalam sintetik air masin (pembentukan air dan air laut) bagi pembentukan air yang mengandungi barium dan kandungan garam yang tinggi pada suhu 40 hingga 90°C pada tekanan atmosfera. Keputusan uji kaji mengesahkan pola kebergantungan keterlarutan bagi kerak medan minyak biasa pada keadaan ini. Pada suhu yang lebih tinggi, kerak bagi CaCO3, CaSO4, dan SrSO4 meningkat manakala kerak BaSO4 menurun disebabkan oleh keterlarutan CaCO3, CaSO4, dan SrSO4 menurun dan keterlarutan BaSO4 meningkat dengan kenaikan suhu. Kata kunci: Masalah pengskalaan; skala keterlarutan; paras kandungan garam tinggi; logam barium tinggi Scale deposition is one of the most important and serious problems which water injection systems are generally engaged in. Scale sometimes limits or blocks oil and gas production by plugging the oil–producing formation matrix or fractures and the perforated intervals. This paper presents a summary of the laboratory measurements of the solubility of common oil field scales in synthetic brines (formation water and sea water) of high–barium and high–salinity formation waters at 40 to 90°C and atmospheric pressure. The experimental results confirm the general trend in solubility dependencies for common oil field scales at these conditions. At higher temperatures the deposition of CaCO3, CaSO4 and SrSO4 scale increases and the deposition of BaSO4 scale decreases since the solubilities of CaCO3, CaSO4 and SrSO4 scales decreases and the solubility of BaSO4 increases with increasing temperature. Key words: Scaling problems; solubility of scale; high salinity; high barium

Offshore oil and gas production worldwide is conducted in increasingly deep waters, leading to more and more stringent demands on line pipes. Higher grades and heavier wall thicknesses in combination with deep temperature toughness properties, good weldability and suitability for sour service applications are among the characteristics called for. It is necessary that pipe manufacturers develop materials to meet these at times conflicting requirements. An alloying concept based on steel with very low carbon content is presented. This type of material provides excellent toughness properties at deep temperatures in line pipe with a wall thickness of up to 70 mm, produced by hot rolling followed by QT heat treatment. Pipes from industrial production of identical chemical composition and heat treatment achieved grades X65 to X80, depending on wall thickness. The properties of the steel used in pipes are presented. The resistance of the pipe material to the influence of sour gas was assessed by standard tests. To demonstrate weldability, test welds were performed and examined.

This article has a simple research question: what determines the risks of oil producing companies listed in Australia and the United States, and are there any differences between their risk attitudes? A literature review is used to develop an integrated theory of company risk that is validated using a hand-collected database covering active oil and gas production companies in Australia and the United States. Risk in both countries proved to be a function of company risk propensity and risk management, which each had a small number of deep-seated drivers spread across company structure, governance and performance. These common risk-related features between companies in geographically remote countries point to the complexity of achieving portfolio diversification.
