Leni completes drilling of fourth Goudron well and finds additional oil reservoir

31st July 2014

Leni Gas and Oil (LGO) has announced that the fourth well of its 30 well development programme on the Goudron Field in Trinidad, GY-667, has been successfully drilled to a total depth (TD) of 4,006 feet measured depth (MD)

Leni Gas and Oil (LGO) has announced that the fourth well of its 30 well development programme on the Goudron Field in Trinidad, GY-667, has been successfully drilled to a total depth (TD) of 4,006 feet measured depth (MD)
The well will now be electronically logged from 1,905 feet to TD prior to the running and cementing of a 7-inch casing to TD

In addition to oil pay in the Goudron Sandstones the well encountered significant gross oil pay in the Gros Morne.  The Lower Cruse was also encountered with oil shows.  GY-667 was deepened by 166 feet below the original intended TD at 3,840 feet MD in order to fully investigate the reservoir zones encountered in the Lower Cruse.

"Well GY-667 not only continues the success of recent drilling, but also appears to have encountered a thinker reservoir interval in the Lower Cruse which adds further production potential and possible reserves to the field," said Neil Ritson, LGO chief executive.

The Gros Morne interval has extensive sandstones with good oil shows whilst drilling and is expected to have comparable reservoir potential to other recently drilled wells.  The well will now be electronically logged from 1,905 feet to TD prior to the running and cementing of a 7-inch casing to TD.

The company announced on 23 July 2014 that GY-667 has already intersected 187 feet of net oil pay in the Goudron Sandstones in the interval from surface to 1,905 feet MD based on analysis of the electric logging.

A full report of the net pay intervals in GY-667 will be announced on completion of the analysis of the logging runs.  GY-667 will be completed as a production well, most likely in the Gros Morne Sandstone, after the drilling of the fourth well from the current pad, GY-668, has been drilled.
