Sinopec announced this week that production at China's largest shale-gas development has jumped 20% year-over-year. This is based on first quarter results that showed natural-gas production from the Fuling gas field in Chongqing reached a cumulative output of 1.78 Bcm, or nearly 63 Bcf. The boost comes after Sinopec brought 28 new wells on stream this year, the state-owned oil and gas producer said in an announcement. Sinopec is China's second-largest gas producer and said during its earnings call that it is aiming for an annual increase in gas output of 10% over the next 3 years. The operator produced a total of 30.2 Bcm in 2020 and is aiming for 34 Bcm this year. Sinopec's next expected milestones are 38 Bcm in 2022 and 42 Bcm in 2023.
Southeast Asian operators sit in the middle of the world's fastest growing economic region where energy demand is expected to double over the next 20 years. But this picture of growth has been juxtaposed with the region's declining oil and gas production--most of which comes from offshore fields--that has left it increasingly reliant on imports from overseas suppliers. The degree to which operators in Malaysia and Indonesia can help counter this trend was the focus of an executive panel last week at the International Petroleum Technology Conference (IPTC). While acknowledging that the region is marked by challenging geologies and mature offshore fields, the executives spoke highly of what the future holds. Several things underpin their optimism, not least of which is the region's rising demand for natural gas.

Al - Mg alloys are extensively used as structural materials in marine applications. Sensitization has emerged as a severe concern during the operation of aluminum vessels, due to the consequent high susceptibility to Intergranular Corrosion - IGC. Herein, a detailed study of sensitization on naturally sensitized, field retrieved, Al-Mg alloy samples, is presented. Specifically, samples from four Hellenic Navy - HN high speed vessels were tested according to ASTM G67 in order to quantify their Degree of Sensitization - DoS and qualified, in terms of grain boundaries (GBs) coverage with β phase with microstructural observation using Scanning Electron Microscopy - SEM and light optical microscopy. Consequently, the correlation of DoS value to the external factors that affect it becomes possible. Remarkably, material under investigation has significantly diverse chemical composition, compared to common marine grade aluminum alloys. Ultimately, correlation of Stress Corrosion Cracking behavior with the microstructure is discussed.
