According to 2006 CNOOC estimates, Pinghus oil reserves are 2.4 million barrels (MMbbl), a small fraction of the estimated total for the East China Sea.

China has identified gas deposits in the X/O trough region, roughly 280 miles (240 nautical miles) southeast of Shanghai. Chunxiao is the largest Chinese gas field and is used on occasion to reference all fields in the area: Baoyunting, Tianwaitian, Duanqiao, Canxue, and Wuyunting.

Tianwaitian began production in the first half of 2006 and as of April 2007 produced 17.65 MMcf per day. Chunxiao, located just 3 miles west of the median line, will eventually link via pipeline to Tianwaitian from where both platforms gas will travel via pipeline roughly 600 miles to an onshore terminal at Ningbo. CNOOC and Sinopec are equal shareholders for natural gas projects in the region.<p></p> </div><span class="cssSubheading1">Japan</span><br><div>Japan is concerned that production at the Chunxiao field is depleting resources from its side of the median line. In the summer of 2005 Japan authorized Teikoku Oil Company to begin exploratory drilling. In September of 2005, Teikoku sent the Ramform Victory to conduct seismic surveys in the X/O trough, but the ship left the area upon the appearance of Chinese warships. Further plans for exploration are on hold pending discussions between Teikoku and the Japanese government regarding the protection of Teikokus workers.<p></p> </div> </td> </tr> </table> <p></p> </td> <td style="background:url(../images/R4_BG.jpg); background-position:right;" align="right"><a href="../index.html"><img src="../images/R4_10.jpg" alt="Country Analysis Briefs" border="0"></a><p></p> <table summary="" class="cssMenu" cellpadding="0" cellspacing="0" align="right"> <tr class="cssTableSpacer"> <td class="cssHeader2White" style="text-align:right; padding-right:10px">March 2008</td> </tr> <tr class="cssTableSpacer"> <td></td> </tr> <tr class="cssMenu_b"> <td><a href="Background.html">Background</a></td> </tr> <tr class="cssMenu_a"> <td><img src="../images/R4_Shadow.jpg" align="right" hspace="0" vspace="0"></td> </tr> <tr class="cssMenu_b"> <td><a href="OilNaturalGas.html">Oil and Natural Gas</a></td> </tr> <tr class="cssMenu_a"> <td><img src="../images/R4_Shadow.jpg" align="right" hspace="0" vspace="0"></td> </tr> <tr class="cssMenu_b"> <td><a href="Territorial_Issues.html">Territorial Issues</a></td> </tr> <tr class="cssMenu_a"> <td><img src="../images/R4_Shadow.jpg" align="right" hspace="0" vspace="0"></td> </tr> <tr class="cssMenu_b"> <td><a href="Timeline.html">Timeline</a></td> </tr> <tr class="cssMenu_a"> <td><img src="../images/R4_Shadow.jpg" align="right" hspace="0" vspace="0"></td> </tr> <tr class="cssMenu_b"> <td><a href="Links.html">Links</a></td> </tr> <tr class="cssMenu_a"> <td><img src="../images/R4_Shadow.jpg" align="right" hspace="0" vspace="0"></td> </tr> <tr class="cssMenu_b"> <td><a href="Sources.html">Sources</a></td> </tr> <tr class="cssMenu_a"> <td><img src="../images/R4_Shadow.jpg" align="right" hspace="0" vspace="0"></td> </tr> <tr class="cssMenu3"> <td>Full Report<br></td> </tr> <tr class="cssMenuRegion"> <td><a href="Full.html" target="_newWin">HTML</a><br></td> </tr> <tr class="cssMenuRegion"> <td><a href="pdf.pdf" target="_newWin">PDF</a><br></td> </tr> <tr class="cssMenu_a"> <td><img src="../images/R4_Shadow.jpg" align="right" hspace="0" vspace="0"></td> </tr> <tr class="cssMenu3"> <td>Contact Info</td> </tr> <tr class="cssMenu2"> <td><span class="cssMenu2Printer"><a href="mailto:cabs@eia.doe.gov">cabs@eia.doe.gov</a><br>(202)586-8800<br><a href="../Contacts.html">[more contacts]</a></span></td> </tr> <tr class="cssMenu_a"> <td><img src="../images/R4_Shadow.jpg" align="right" hspace="0" vspace="0"></td> </tr> </table> </td> </tr> <tr> <td colspan="3"><script language="JavaScript">InsertEIAFooterCode();</script></td> </tr> </table> </body> </html>
