The UAE-based Mubadala Petroleum has found new oil-bearing zones at the Manora oil field in the Northern Gulf of Thailand.

The company encountered the new hydrocarbons during the drilling of the Manora-8ST1 appraisal well in the G1/48 concession.

The Manora-8ST1 appraisal well was spud using the Ensco 115 jack-up drilling rig to procure data about multiple reservoir zones up-dip from MNA-18 in the eastern fault block as well as delineation of the 490-60 sands in MNA-18.

Furthermore, the scope of works included identifying the presence of additional hydrocarbon sources at 300, 400 and 500 levels.

Tap Oil , the 30% partner of the Mubadala-operated resource, stated that the Manora-8ST1 well reached final total depth of 2,458m MDRT.

“The company encountered the new hydrocarbons during the drilling of the Manora-8ST1 appraisal well in the G1/48 concession.”

The 490-60 sand was found to be well developed with 86 feet pay, while 400 sands hosted seven feet pay.

The well encountered 106 feet pay at five sands at the 300 level and 108 feet pay at three sands at the 500 level.

Additionally, the new 300 and 500 sands were found to exhibit similar characteristics compared to other Manora oil field wells with good porosity, pressure and permeability.

These 300 and 500 sands will now be included in the updated reserves and resources statement as new contingent resources in the Manora oil field.

The drilling rig will now commence a two-well development drilling programme, which includes MNA-20 and MNA-21.
