The future energy mix must be wide-ranging and diverse to meet the needs both of the environment and the people living on the planet. New companies have begun to bring geothermal energy to areas that aren’t adjacent to volcanoes or that don’t have access to tectonic settings, which allow for an easy harvesting of the Earth’s heat. Some are embracing the niche operation of repurposing traditional geothermal wells and non-producing oil and gas wells. Others are promoting widespread geothermal energy through deep vertical and multilateral wells that can bring heat and electricity to the masses. </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 December, 2022</span></div> </div>  <div class="list-with-images explorer-articles dnnClear" itemscope="" itemtype="http://schema.org/Article">  <div class="litImage Explorer Article 1plus4 Rotation 3D Seismic Amplitude Versus Offset Analysis Basin Modeling and Geochemistry Basins Analysis Business and Economics Clastic Rocks Clastics Coring/Core Analysis Deep Basin Gas Deep Sea / Deepwater Deepwater Depositional Models/Processes Drilling Drilling Support/Planning Economics Engineering Fluvial Deltaic Systems Geologic Age Geology Geophysics Geophysics Interpretation Mapping Seismic Data 2D Mapping Seismic Data 2D 3D Mapping Seismic Data 3D Marine Member Mesozoic Offshore Phanerozoic Resource Estimation Sedimentology and Stratigraphy Seismic Student " style="position: relative;"> <a href='https://www.aapg.org/publications/news/explorer/details/articleid/64303' > <div class="image-overlay "></div> <noscript data-slimmage>  <img itemprop="image" class=" lazy " data-original="/Portals/0/PackFlashItemImages/WebReady/geophysics-has-proven-key-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/geophysics-has-proven-key-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 3D Seismic Amplitude Versus Offset Analysis Basin Modeling and Geochemistry Basins Analysis Business and Economics Clastic Rocks Clastics Coring/Core Analysis Deep Basin Gas Deep Sea / Deepwater Deepwater Depositional Models/Processes Drilling Drilling Support/Planning Economics Engineering Fluvial Deltaic Systems Geologic Age Geology Geophysics Geophysics Interpretation Mapping Seismic Data 2D Mapping Seismic Data 2D 3D Mapping Seismic Data 3D Marine Member Mesozoic Offshore Phanerozoic Resource Estimation Sedimentology and Stratigraphy Seismic Student " id="pfid_64303"> <div class="author content-type" style="margin-bottom: 0px;"> <span class="content-type">Explorer Article</span> <span itemprop="author">By Heather Saucier</span> </div> <div class="h5" itemprop="headline"> <a itemprop="url" href='https://www.aapg.org/publications/news/explorer/details/articleid/64303' >Geophysics Has Proven Key in Giant Stratigraphic Fields Discoveries</a> </div>  <div class="show-more-snippet fade"><div class="summary" itemprop="description"><p>In the world of oil and gas, an increasing number of plays in stratigraphic traps are being made – in large part due to ever-evolving seismic technology.
