Individuals need to be proactive in recognizing the additional needed skill sets and work to acquire them. Employers should be developing and providing needed training for their employees to expand their skill sets matching the expanded energy landscape. Maintaining current and developing new competencies starts with our educational institutions where changes are taking place to evolve curricula to provide graduates with the skills for a long, successful careers. It also means we focus our efforts to use our current competencies in mitigating climate change concerns, as in reducing emissions and capturing and storing CO 2 and producing new sources of energy like geothermal. This means we need to continue the development of advanced technologies and deploy them to produce increased volumes of oil and natural gas. The above information indicates that the future strategy of professionals in petroleum engineering is to leverage our strength to safely deliver the needed energy for the world as we have been doing for more than 100 years. However, I converted the values from exajoules (1e18 joule, a measurement unit I cannot relate to) to BOE using a conversion factor of 1 exajoule = 163.45e6 BOE. I obtained the information from the sources cited earlier. The tables show the changes in global primary energy demand as well as the changes in different regions. Shares of Latin America and the Middle East will stay around the current levels of 7% and 4%, respectively, while Africa’s share will increase from about 4 to 5%. Projections for the regional share of the world economy indicates that Asia will have about 43% of the world economy by the year 2040 (currently at 35%) followed by North America at about 24% (currently at 26%) and the EU and the UK at about 17% (currently at 20%). Right now, this investment is around $1,700 billion. For the new energy sources to reach the level needed for IEA’s Net Zero 2050 target, annual investment in the range of $2,600 billion is needed. Following the COVID-19 pandemic, when investment dipped to $600 billion, investments have gradually increased but are not yet to the desired levels. Needed investment in oil and gas should be about $900 billion annually. The required levels of investment to provide the world with its energy needs are lagging, and there will be a shift in the regional demand of energy. This indicates that multiple solutions are needed to satisfy energy demand, oil and gas will remain essential for decades, and technological developments will continue to be needed in all sources of energy and may end up changing the mix of energy sources in the future.ĭata and projections also show two important points. Consensus also appears to indicate that policy will influence the speed of change of the energy landscape, that energy transition will vary by region, and that the pace of the energy transition will depend on costs, infrastructure, project execution, and geopolitics. ANSI/ASME B94.11M-1993ĭrill Bits, also called Twist drills are available with straight or tapered shanks though the most common drill bits will have straight shanks.Projections for fossil fuels demand until 2050.įor example, as I am writing this column, Norway approved more than $18 billion investments to develop 19 oil and gas fields.
