The company said an over pressured interval was encountered with natural gas and saltwater inflows causing the drill pipe to wedge in the well hole, prior to running an intermediate casing string.
After retrieving key bottom hole equipment and working to free the drill pipe, a decision was made to sidetrack the well, the company added.
Golden Gate forecasts it would take about eight days to reach the required depth to set the intermediate casing string at a cost of $US350,000.
The Bullseye prospect has a target reservoir potential of 12.5 million barrels of oil and 33 billion cubic feet of gas.
If Jumonville-1 is successful, several follow-up drill targets have been identified.
Participants in the Jumonville-1 well are Golden Gate Petroleum (43.33%), Modena Resources (15%), Pantheon Resources PLC (15%), Eastern Advisors (20%) and Nuenco (6.67%.
