He made the remark in the context of a CEO discussion about the industry and its response to the energy transition. The truth of his observation is much broader. As AAPG identifies and prepares new ways to serve its members and attract new members for decades to come, it’s important for us to understand the facts, as best we can. If our strategy is to succeed, it must be based on reality. One reality we face in the United States and Europe is dwindling enrollments in the geosciences, and the jobs these graduates are getting are rapidly changing. </p></div></div><a class='show-more'>Show more</a> </div> <meta itemprop="inLanguage" content="English"> <span style="display: none;" itemprop="publisher" itemscope="" itemtype="https://schema.org/Organization"> <span itemprop="name">American Association of Petroleum Geologists (AAPG)</span> <meta itemprop="logo" content="https://img.aapg.org/Portals/0/images/_site/AAPG-logo-footer.png"> </span> <div class="morelink">Added on <span itemprop="datePublished" class="schema">01 March, 2023</span></div> </div>  <div class="list-with-images explorer-articles dnnClear" itemscope="" itemtype="http://schema.org/Article">  <div class="litImage Explorer Article 1plus4 Rotation Alternative Resources Business Business and Economics Climate Change Climate Change Environmental Environmental Ethics Member Student " style="position: relative;"> <a href='https://www.aapg.org/publications/news/explorer/details/articleid/64989' > <div class="image-overlay "></div> <noscript data-slimmage>  <img itemprop="image" class=" lazy " data-original="/Portals/0/PackFlashItemImages/WebReady/the-changing-face-hero.jpg?width=200&height=200&mode=crop&anchor=middlecenter&encoder=freeimage&progressive=true&quality=90&scale=both&bgcolor=ffffff" src="/portals/0/PackFlashItemImages/WebReady/the-changing-face-hero.jpg?width=200&height=200&mode=crop&anchor=middlecenter&encoder=freeimage&progressive=true&quality=90&scale=both&bgcolor=ffffff" alt="AAPG"> </noscript> </a> </div> <div class="text Explorer Article 1plus4 Rotation Alternative Resources Business Business and Economics Climate Change Climate Change Environmental Environmental Ethics Member Student " id="pfid_64989"> <div class="author content-type" style="margin-bottom: 0px;"> <span class="content-type">Explorer Article</span> <span itemprop="author">By Barry Friedman</span> </div> <div class="h5" itemprop="headline"> <a itemprop="url" href='https://www.aapg.org/publications/news/explorer/details/articleid/64989' >The Changing Face of the Geoscience Workforce</a> </div>  <div class="show-more-snippet fade"><div class="summary" itemprop="description"><p>Considering climate change impact mitigation, the world’s need for raw materials, new ways of addressing energy needs and management of water resources — not to mention its own internal “crew change” — the geoscience community now faces a uniquely tumultuous time.

to reuse their infrastructure for geothermal energy production. These inactive wellbores provide access to subsurface reservoirs of hot water and rock that can be tapped for the commercial development of deep geothermal direct use or power generation projects. Repurposing retired wells reduces costs and environmental impacts versus drilling new wells. It provides a beneficial use for legacy oilfield assets. Geothermal power holds promise as a clean, renewable baseload energy source that could help transition communities away from declining fossil fuel production. Reusing existing well infrastructure for geothermal could support more stable, diversified local economies while making use of energy locked in the subsurface to provide low-carbon heating and electricity for homes and businesses. </p></div></div><a class='show-more'>Show more</a> </div> <meta itemprop="inLanguage" content="English"> <span style="display: none;" itemprop="publisher" itemscope="" itemtype="https://schema.org/Organization"> <span itemprop="name">American Association of Petroleum Geologists (AAPG)</span> <meta itemprop="logo" content="https://img.aapg.org/Portals/0/images/_site/AAPG-logo-footer.png"> </span> <div class="morelink">Added on <span itemprop="datePublished" class="schema">07 December, 2023</span></div> </div>  <div class="list-with-images explorer-articles dnnClear" itemscope="" itemtype="http://schema.org/Event">  <div class="litImage Webinar 1plus4 Rotation AAPG Academy Alternative Resources Hydrogen Energy Renewable Energy Virtual " style="position: relative;"> <a href='https://www.aapg.org/videos/webinar/articleid/67446' > <div class="image-overlay Virtual "></div> <noscript data-slimmage>  <img itemprop="image" class=" lazy " data-original="/Portals/0/PackFlashItemImages/WebReady/webinar-hq-2023-geologic-hydrogen-hero.jpg?width=200&height=200&mode=crop&anchor=middlecenter&encoder=freeimage&progressive=true&quality=90&scale=both&bgcolor=ffffff" src="/portals/0/PackFlashItemImages/WebReady/webinar-hq-2023-geologic-hydrogen-hero.jpg?width=200&height=200&mode=crop&anchor=middlecenter&encoder=freeimage&progressive=true&quality=90&scale=both&bgcolor=ffffff" alt="AAPG"> </noscript> </a> </div> <div class="text Webinar 1plus4 Rotation AAPG Academy Alternative Resources Hydrogen Energy Renewable Energy Virtual " id="pfid_67497"> <div class="author content-type" style="margin-bottom: 0px;"> <span class="content-type">Webinar</span> <span itemprop="author">By Peter Lloyd</span> </div> <div class="city-state-country">Virtual Webinar</div> <div class="dates"><span class="weekday schema">Tuesday, </span>19 December 2023<span class="time schema">, 12:00 p.m.–1:00 p.m.</span></div> <div class="h5" itemprop="headline"> <a itemprop="url" href='https://www.aapg.org/videos/webinar/articleid/67446' >Geologic Hydrogen: Global Occurrences and Case Studies</a> </div>  <div class="show-more-snippet fade"><div class="summary" itemprop="description"><p>Global Occurrences and Case Studies: In this webinar, you'll learn about the quickly expanding world of exploration for geologic hydrogen. Geoff Ellis of the USGS details the nature and origin of natural hydrogen, the reasons for accumulations, and effective exploration strategies. He then reviews locations in the world where reserves of natural hydrogen have been found, and discuss current activities and trends. Avon McIntyre of Hyterra discusses the company's drilling activities in pursuit of geologic hydrogen, including operations along the Nemaha Ridge in the central U.S. The project includes Project Geneva in Nebraska, and Nemaha Ridge, Kansas, both in the U.S. </p></div></div><a class='show-more'>Show more</a> </div> <meta itemprop="inLanguage" content="English"> <span style="display: none;" itemprop="publisher" itemscope="" itemtype="https://schema.org/Organization"> <span itemprop="name">American Association of Petroleum Geologists (AAPG)</span> <meta itemprop="logo" content="https://img.aapg.org/Portals/0/images/_site/AAPG-logo-footer.png"> </span> <div class="morelink">Added on <span itemprop="datePublished" class="schema">19 December, 2023</span></div> </div>     </div> <script type="text/javascript"> /*var moreText = "Show details", lessText = "Hide details", moreButton = $("a.readmorebtn"); moreButton.click(function () { var $this = $(this); $this.text($this.text() == moreText ? lessText : moreText).nextAll(".more").slideToggle("fast"); }); */ $(".show-more").each(function() { var parent_id = "#" + $(this).parent("div").attr("id"); $(this).click(function() { var minimum_height = (parseInt($(parent_id + " .show-more-snippet .summary").css("line-height"), 10) * 5) + "px"; console.log(minimum_height); //if($(parent_id + ' .show-more-snippet').css('height') != '35px'){ if($(parent_id + " .show-more-snippet").css("height") != minimum_height){ //$(parent_id + ' .show-more-snippet').stop().animate({height: '35px'}, 200); $(parent_id + " .show-more-snippet").stop().animate({height: minimum_height}, 200).addClass("fade"); $(this).text("Show more"); }else{ $(parent_id + " .show-more-snippet").css({height:"100%"}).removeClass("fade"); var xx = $(parent_id + " .show-more-snippet").height(); //$(parent_id + ' .show-more-snippet').css({height:'35px'}); $(parent_id + " .show-more-snippet").css({height: minimum_height}); $(parent_id + " .show-more-snippet").stop().animate({height: xx}, 400); // ^^ The above is beacuse you can't animate css to 100% (or any percentage).
