At present, transportation of the oil and gas resources in our country relies mainly on long-distance buried pipeline; pipe is commonly steel spiral welded pipe. The long-distance pipeline adopts buried way, crossing section of the complex terrain. Different soil properties, and soil have different degree and strong corrosion to the pipe, and the leakage point also is not easy to be found in time, as well as the underground pipeline maintenance needs a large number of earthwork, more hard than the construction of new line. Therefore, long-term, safe and steady operation is the main task of long-distance pipeline. How to prevent the corrosion of buried pipeline damage has long been an important part of pipeline engineering.

Abstract The model of Blue Economy by G. Pauli is inspired by nature. Its main task is to develop innovative methods based on the use of available resources and the use of nature-based solutions. The principle of Blue Economy requires close cooperation of research and development and business activities; and it seeks implementation options in the structure of local economies. Based on the theory known as ‘blue economy’, in order to overcome certain problems of mankind – for example, energy production and consumption –, we must recognize and use some methods given to us by nature. This may be provided to us by new innovations that think according to system theory, that is, occupy the exceptionally effective self-regulating processes of nature in the economy. Methanol may play a key role in succeeding sustainability regarding nature, economy and society. Methanol economy can contribute to reducing human impacts on Earth’s climate by reversing atmospheric carbon dioxide, and it provides the opportunity to get rid of our dependence on dwindling oil and gas resources.

ExxonMobil Australia Pty Ltd’s subsidiary, Esso Australia Resources Pty Ltd (ExxonMobil), and BHP Billiton jointly own and operate an LPG fractionation facility at Long Island Point, near Hastings in Victoria. This facility began operating in 1970 as part of the overall development of Gippsland oil and gas resources. The facility had a nominal design life of 30 years; however, the facility will be required to operate for many more years, given the significant gas reserves remaining in Bass Strait. A plan was developed to identify and progress plant facility upgrades to ensure continued, safe operation to life end. Nine separate projects with a total value in excess of A$250 million were developed and are now in various stages of progress. The key projects include: refrigerated LPG storage tank refurbishment, fire system upgrade, a new control room and control system, and plant emergency shutdown system upgrades. These projects focus on achieving high standards of safe operations and long-term reliability through application of advances in technology to ready the facilities for their remaining life.

In countries with industrialized agriculture, the contribution of fossil energy equals or exceeds the energy provided to society in food. Poland is one of the countries which, in the absence of its own sufficient oil and gas resources, is forced to import these fossil fuels in order to benefit from modern solutions in the field of food production and distribution. This situation poses a serious threat to food security if there is a prolonged shortage of energy from such sources. Using the example of Poland, the following were identified: the causes and level of agricultural dependence on fossil fuels, energy threats to agriculture and energy source alternative to fossil fuels. The results of these considerations indicate that Poland is not a country that has irretrievably lost its ability to restore its food self-sufficiency in the event of loss of access to external sources of fossil fuels.

AbstractThis paper examines the environmental history of petroleum pipeline canals and their impact on wetland loss in Coastal Louisiana, and how politics and wetland science have shaped restoration efforts over time. Since the 1930s, Coastal Louisiana’s wetlands have provided America with abundant oil and gas resources. The expansion of this vital energy production and transportation corridor, however, has come with a huge environmental price tag, one that will persist for generations, long after the hydrocarbons are depleted. Louisiana has the world’s seventh largest wetlands and produces the lion share of America’s domestic oil production. Yet Louisiana’s wetlands are disappearing and have been for sometime, along with the habitat, wildlife, culture, and traditional socio-economic activities that is unique to the region. Most of this loss has occurred between the 1950s and late 1970s, the era of intense petroleum production. The reasons for this high loss rate are complex and unique, involving a mixture of both natural and human-induced changes over time. Scientists argue that one of the major causes of this wetland loss has been the long-term direct and indirect impacts of oil-led development, namely the construction of pipeline, access, and navigation canals through the marshes, barrier islands, and bays. The energy and environmental tradeoffs have been particularly challenging given the enormous oil resources produced in the region over the decades and because of the Mississippi Delta’s complex geologic structure. Understanding how the two have interacted over time raises important questions about ecological restoration and the long-term impacts of energy production on fragile landscapes.

The Bojonegoro District Government took the initiative to establish the Bojonegoro Petroleum and Natural Gas (Oil and Gas) Endowment Fund. The establishment of this Oil and Gas Endowment Fund aims to ensure the existence of a saving fund for future generations when oil and gas and gas in the region has run out. This idea is in line with the fact that in the long term Bojonegoro will contribute significantly to domestic oil and gas production and also the fact that Bojonegoro has succeeded in alleviating poverty, in one area that was once considered the poorest district in Java. The establishment of the Oil and Gas Endowment Fund is also based on consideration of avoiding the curse of natural resources. Reflecting on the experience of regions rich in natural resources, including oil and gas resources, where the level of human welfare and development is lower than in areas of poor natural resources. The level of social conflict is quite high, environmental damage is quite severe, Dutch desiase, excessive spending (over spending), corruption thrives and more.

Oil and natural gas have increasingly become potential resources for the socio-economic development of Tanzania. Understanding the factors on its sustainability remains of critical importance. This study intended to analyze the factors for the sustainable development of oil and gas resources in Tanzania. We collected quantitative data from 250 participants through a questionnaire, whereas data collected were analyzed using descriptive and inferential statistics. Results show that institutional development, enterprise development, and good governance are pertinent factors for the sustainable development of oil and gas resources in Tanzania. The study offers the implication that to realize the benefits of oil and gas resources for the long-term development of Tanzania, policymakers should ensure institutional and enterprise development, and promotion of governance framework to enhance transparency and accountability in the oil and gas sector. Moreover, we recommend that the realization of long-term extraction and sustainable development of oil and gas resources in Tanzania, robust policies, strategies, good governance frameworks and combined efforts of the government, oil companies, and private sector, civil organizations, and citizens’ participation in the management of oil and gas resources is of critical importance.

Water Pressure Testing

Worldwide, the pipeline mileage has increased dramatically since 1948 when the industry began to keep mileage statistics for pipeline construction, especially in China. Before operating long distance oil and gas pipelines, the pressure testing for tightness and strength is of great importance for ensuring operating safety. Water is used as service fluid for the pressure testing due to its safety, and long distance pipeline is divided into a number of small sections according to complex terrain conditions. Segmental water pressure testing is now very frequently used in the oil and gas industry, ensuring safety and efficient construction of pipelines. However, some new problems may arise, in practice, for the pigging process, following water pressure testing. Based on the review of previous papers about pipes accidents, the causes can be classified into hydraulic and nonhydraulic aspects. With the method of characteristic (MOC) and basic theory of gas–liquid two-phase unsteady flow, a mathematical model is developed to simulate the hydraulic transients during the pigging process. The model has been applied to some segmental pipes in China to predict varying pressures under complex terrain conditions. Pressure pulses predicted at the end of pigging in the numerical results have also been found to occur in field trials. The analysis shows that pressure pulses may cause overpressure accidents due to vapor cavity collapse. The techniques in this paper can give reasonable instructions in long distance pipeline constructing, promoting the development of Chinese oil and gas industry.

Significance Ahead of COP26, Saudi Arabia announced a Green Initiative and ambitious targets including net-zero carbon emissions by 2060. At the same time, officials are arguing that continued development of oil and gas resources is compatible with pursuing the long-term goal of decarbonisation. Impacts Saudi Arabia may struggle to wean the electricity sector off its near-total reliance on fossil fuels. State-owned firms Aramco and Sabic will seek to develop new revenue streams from technologies that contribute to global decarbonisation. Shareholder pressure on international energy companies may give Aramco a short-term boost, but a supply squeeze risks unsustainable prices.

Abstract With the increasing scale of the exploitation of ocean oil and gas resources, the decomposition of natural gas hydrate and the exploitation of submarine oil will damage the engineering mechanical structure of submarine sediments, leading to submarine collapse, landslide, even earthquake and other geological disasters, seriously threatening the exploration and exploitation of Marine resources. Therefore, it is necessary to develop a deep-seabed drilling robot to carry out real-time long-term monitoring of changes in the seabed environment by carrying sensors and detection devices. This paper will describe the design structure of the drilling robot, and explain the working process through that the drilling robot is released from the sea bed into the stratum of the mining area, and can achieve autonomous drilling and steering functions in the seabed stratum. In this paper, theoretical analysis and simulation verification will prove the feasibility of the robot moving in the stratum.

Oil gas is the most clean fuel. Till 2020, the requirement of oil gas will increase 104%, but consumers are mainly live in developed cities, and oil and gas resources are located in ice field, hungriness, ocean and polar place. That is, the undeveloped resources are remote from the cities. It means, long distance transportation of gas is needed and higher grade pipeline steels must be developed. The second west-east gas project in china will use X80 grade steel in whole line, and as the exploitation of oil and gas resources have been diverted to outlying districts, and the need of high transport pressure for increasing gas delivery efficiency, the X100 pipe line steel will be mostly used before long. In this paper, the changes of micro structure and property after reheating treatment of X100 are discussed. This work will be helpful for future use of X100 bend pipes. The study has shown that for X100 steel which contains banite micro structure with dispersed residual austenite and Fe3C phase. The micro structure is the most homogenous when tempered at 550°C. When reheating regime is quenching from 950°C and tempering at 550°C, the microstruecture is B+PF+ P and the hardness of these steels matches with pipe. The fractotraph showed that these samples has adequate dimples in pars fibrosa, radiation area and shear zone, respectively, at −20°C. This indicates that when X100 pipe steels are reheattreated with this technique, it could gain right toughness.
