Kings Dome South Prospect - Bienville Parish, LA
Smackover Structure/Reef
Haynesville Shale
James Reef
Summary. In 2003, El Paso used 3D seismic to discover the Kings Dome Field by drilling the El Paso 1 Foster 35 well into an Upper James carbonate buildup at about 7500' TVD adjacent to the King Salt Dome. It has produced more than 5 BCF from this one well. Initial production approached 1 BCF/month. Its production dropped precipitously and now only produces 200 MCF/d. In 2006 El Paso used 3D seismic to discover gas in the El Paso 1 Pardee 34 well from a separate Lower James carbonate reservoir. This well has also produced more than 5 BCF and is currently making more than 6 MMCFG/d (5/08) at the same depth. BKE discovered that these James reefs continue along the west flank of a salt withdrawal syncline to the SSW based on 2D seismic, geological mapping and other datasets. Upon investigating the James, it was found that withdrawal syncline sits directly above a Smackover structural high that may be reefal - similar to the Cotton Valley Reefs in East Texas. Additionally, the salt withdrawal events fractured the ubiquitous Haynesville/Bossier shale significantly enhancing the deliverability this gas resource formation. From one wellbore, all three formations can be evaluated. Total potential could surpass 50 BCF/well.
