Tullow Oil reported that the Ngamia-1 exploration well onshore Kenya in Block 10BB has now been drilled to an intermediate depth of 4,970 feet (1,515 meters) and the total net oil pay encountered so far has increased to in excess of 328 feet (100 meters) across multiple reservoir zones.

Following the initial announcement on March 26, 2012, that Ngamia-1 had encountered in excess of 66 feet (20 meters) of net oil pay, the well has now been deepened from 3,415 to 4,970 feet (1,041 meters to 1,515 meters). A sidetrack was required in this section and following completion of logging and sampling in difficult hole conditions, a total pay count greater than 328 feet (100 meters) has now been discovered over a gross oil bearing interval of 2,133 feet (650 meters). Oil samples with an API greater than 30 degrees have been recovered to surface from the newly drilled section with similar properties to the light waxy crude encountered in the upper reservoir zone.
