EIA Short-Term Energy Outlook (STEO)
The following is the October 2017 instalment of the monthly forecast provided by the U.S. Energy Information Administration.

Oil and Gas to Supply Nearly Half of Global Primary Energy In 2050
DNV GL forecasts world energy demand will plateau from 2030. Oil and gas will supply 44% of global primary energy in 2050 and gas will be the largest single source of energy from 2034. Significant investment will be needed across the oil and gas value chain.

Singapore Seeks to Be Hub

Technology

Low-Speed Low-Pressure X-DF Technology
When the development of the two-stroke low-pressure DF lean-burn technology started, the extensive experience from Wärtsilä’s four-stroke developments could be utilized as a base in several technology areas. These include engine automation and control, pilot injection, gas supply system and engine testing to mention a few. Still, while having some of the technologies in place, the characteristics of the two-stroke engine required additional fundamental developments, which at the same time turned out to open new opportunities. One example is the differences introduced by the low engine speed, giving more time for gas mixing but also requiring better control of the combustion speed. Another difference is the uniflow scavenging process of the two-stroke engine, which on one hand is enabling certain stratification of the air/gas mixture, fresh air and exhaust gas.

Guideline Shows How to Make Oil and Gas Industry Cyber Secure
Digitalization benefits the oil and gas industry but increases cyber risk; most oil and gas companies were hit by a cyber incident in 2016. DNV GL’s new Recommended Practice details how to build cyber security with the emphasis on operational technology.
