class="ttl-h1">Development of Iwafune-oki Oil and Gas Field</h1> <div class="col-2 col-clm2-1"> <p>Discovered in 1983, Iwafune-oki Oil and Gas Field is one of the largest offshore oil and gas fields in Japan. It is located 30km northeast of Niigata City, 4km off the mouth of the Tainai River of Tainai City. Production and development of crude oil and natural gas in this offshore oil and gas field are underway by three companies: Japan Petroleum Exploration Co. Ltd., JAPEX Offshore Ltd., and our company.<br>As a result of seismic survey carried out with air guns in the aforementioned region in 1982, it was determined that stratigraphic trap structures capable of storing oil and natural gas existed there. Furthermore, because geological conditions in the surrounding land and coastal areas were judged to have a high potential of producing oil and gas, four exploration wells were drilled in 1983-1984. All of these exploration wells succeeded in producing oil and gas, assuring that Iwafune-oki Oil and Gas Field would be established.<br>Based on these successes, the geological and structural analysis, reservoir evaluations, calculation of reserves, and feasibility studies carried out for the aforementioned structures from October 1984, it was judged that development of the offshore oil and gas field could be proceeded on the Iwafune-oki structure, and it was decided development would be commenced in March 1989. This offshore oil and gas field has continued to be operated stably since it started production in 1990.</p> <figure><img src="/eng/products/basic-chemicals/img/bc-gas-field_p01.jpg" alt="Photo: Iwafune-oki Oil and Gas Field" width="221"></figure> </div> </section> </div>     <aside id="localMenu"> <nav> <dl> <dt class="lm-categoryTtl sp-boxBreak"><a href="/eng/products/">Products</a></dt> <dd> <ul class="lm-list sp-boxBreak"> <li class="lm-noCurrent"><a href="/eng/products/basic-chemicals/bc-div1.html" class="arw">Green Energy & Chemicals Business Sector</a> <ul> <li><a href="/eng/products/basic-chemicals/bc-div1.html">C1 Chemicals Division</a></li> <li><a href="/eng/products/basic-chemicals/bc-div2.html">High-performance Products Division</a></li> <li><a href="/eng/products/basic-chemicals/bc-div5.html" class="arw">Energy Resources & Environmental Business Division</a> <ul> <li><a href="/eng/products/basic-chemicals/what.html">What is natural gas?</a></li> <li><a href="/eng/products/basic-chemicals/drilling.html">Development of Higashi-Niigata Oil and Gas Field</a></li> <li><a href="/eng/products/basic-chemicals/geothermal.html">Hachimantai Geothermal Development</a></li> <li><a href="/eng/products/basic-chemicals/gas-field.html">Development of Iwafune-oki Oil and Gas Field</a></li> </ul> </li> <li><a href="/eng/products/basic-chemicals/bc-div6.html">Life Science Division</a></li> <li><a href="/eng/products/basic-chemicals/capacity.html">Production Capacities for Main Products</a></li> </ul> </li> <li class="lm-noCurrent"><a href="/eng/products/specialty-chemicals/sc-div1.html" class="arw">Specialty Chemicals Business Sector</a> <ul> <li><a href="/eng/products/specialty-chemicals/sc-div1.html">Inorganic Chemicals Division</a></li> <li><a href="/eng/products/specialty-chemicals/sc-div2.html">Engineering Plastics Division</a></li> <li><a href="/eng/products/specialty-chemicals/sc-div3.html">Optical Materials Division</a></li> <li><a href="/eng/products/specialty-chemicals/sc-div4.html">Electronics Materials Division</a></li> <li><a href="/eng/products/specialty-chemicals/sc-div5.html">Oxygen Absorbers Division</a></li> <li><a href="/eng/products/specialty-chemicals/capacity.html">Production Capacities for Main Products</a></li> </ul> </li> </ul> <dl id="lm-listProducts" class="lm-listCategory"> <dt>Product Search</dt> <dd> <ul> <li><a href="/eng/products/#products-tab01">Search by product category</a></li> <li><a href="/eng/products/#products-tab02">Search by product application</a></li> <li><a href="/eng/products/#products-tab03">Search by Business</a></li> <li><a href="/eng/products/#products-tab04">Search Alphabetically</a></li>  <li class="keyword"> <div class="form-setSuggest"> <form action="/eng/products/#products-search-box" method="get"><span class="text">Keyword search</span><span class="form"><input type="search" name="search" placeholder="product name, keyword" class="text" id="kwsearch"><button type="submit" class="mf_finder_searchBox_submit"><span></span></button></span></form>  <div id="suggest" style="display:none;"></div> </div> </li> </ul> </dd> </dl> </dd> </dl> </nav> </aside>  </div>  </main> <footer id="footer"> <div id="footerArea">  <div class="contentsInner ftrInner"> <div id="ftrMenu-block" class="col-2 col-clm1-2"> <div id="ftr-logo"> <a href="/eng/"><img src="/eng/shared/img/ftr-logo.svg" alt="MGC Group logo"></a> <ul class="ftr-sns"> <li><a href="https://www.youtube.com/channel/UCRVaVQrnl8KbJD1hafPJ2ag" target="_blank"><img src="/eng/shared/img/youtube_icon.png" alt="youtube logo"></a></li> </ul> </div> <div id="ftrSubMenu"> <ul> <li><a href="/eng/sitemap.html">Sitemap</a></li> <li><a href="/eng/privacy/">Privacy Policy</a></li> <li><a href="/eng/sns_policy.html">MGC’s Social Media Policy</a></li> </ul> <ul> <li><a href="/eng/site.html">Terms of Use</a></li> <li><a href="/eng/accessibility.html">Web Accessibility Policy</a></li> </ul> </div> </div> </div>  <div id="ftr-copyright"><div class="contentsInner"><p>Copyright © MITSUBISHI GAS CHEMICAL COMPANY, INC.
