In order that the production and profits of petroleum companies do not decline, new oil field need to be discovered and exploited. Many of these new discoveries are offshore deepwater fields. However, the drop in oil prices in the last few years has made this type of exploration, which is already challenging in itself, even more difficult, so that companies are postponing or even canceling several deepwater projects. Innovation, new technologies and new concepts of oil and gas production and processing are necessary to make deepwater projects feasible and increase their competitiveness. The aim of this paper was to analyze the subsea processing of oil production as a strategy to reduce both capital and operating costs to enable remote offshore exploration. In addition, a discussion of the benefits and challenges of this strategy was also presented. It also includes a case study at the Lula field, in Brazilian pre-salt. Results demonstrate that the use of subsea separation has great potential to reduce OPEX and CAPEX on offshore projects. The current case study demonstrates a cost reduction due to the investment in the separators of around US$ 6.1 billion, a reduction about 6 to 12 times in the power needed to lift the production and a reduction of about 5 to 7 times in the expenditures with natural gas as fuel for the evaluated scenarios.

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

Subject Cuba's energy troubles. Significance With a previously generous Venezuela facing economic crisis and the United States tightening sanctions, Cuba’s ability to augment its limited domestic oil and gas production is severely constrained. It lacks the export earnings to invest in new technologies and power generating capacity that could ease its fuel supply problems. Russia and China have spoken of offering assistance, but neither is inclined to provide handouts in the absence of commercial returns. Impacts Cuba has tried to trade more with Algeria and Angola but remains vulnerable to international oil price shifts. As a major producer of both sugar and biofuels, Brazil could provide a model for Cuba’s biofuel plans. Cubans are resilient and accustomed to hardship; the country’s looming economic troubles are unlikely to trigger serious unrest.

Net Zero

The Paris Agreement, signed in 2016, has the objective of limiting the global temperature rise to 1.5°C to substantially reduce the effects of climate change. To achieve this objective, significant and unprecedented deep cuts in carbon emissions are required, as set out in the Intergovernmental Panel on Climate Change’s special report on Global Warming of 1.5°C released in October 2018. To enable this ambitious target, global reductions in carbon emissions will need to be markedly reduced to an average of net zero by 2050 and, as such, will have profound effects on hydrocarbon (oil and gas) production in the coming decades. This paper presents a road map of opportunities for the reduction of carbon emissions from hydrocarbon production, specifically natural gas. It includes technologies for reducing carbon emissions from process streams and utility streams. A case study is used to illustrate the opportunities, along with a discussion on technology readiness for several options.

The oil and gas production sector in Western Australia has grown dramatically in recent years and now represents the largest resource sector in the State economy. The industry has a very promising future but it faces a number of challenges if it is to achieve its full potential. Its production location in remote parts of the State confers both advantages and disadvantages. Chief among the disadvantages is the challenge of convincing the community and government of the benefits from the industry when many of those benefits are not apparent to the majority of the population. The emphasis in this paper is on economic impacts, social benefits and community attitudes.WA has produced about 820 million barrels of oil and 2000 million barrels of natural gas when gas is calculated in energy equivalent terms. Petroleum energy production has increased dramatically over the last 15 years and the State is now a substantial energy exporter. Petroleum sources provide the energy for over 85% of the final energy used in the State. Total industry investment over the last 18 years has been nearly $21,000 million for an average of $3.2 million each day. Direct employment by petroleum companies is around 2,500 people with flow-on employment in the services sector estimated at over 17,000 people. Petroleum companies have been major contributors to government revenue and to the development of remote regions in WA.
