UK based oil and gas company Soco has reached total depth at the wildcat exploration well Kinganga Nyanya-1 (KNY-1) in the Nganzi Block onshore Congo, and the company drilled the well to 1,164m measured depth.

The well drilled good source rock shales in the middle and Lower Bucomazi formation, interbedded with Lower Bucomazi sands.

It also encountered the target Lucula formation sands although these were not hydrocarbon bearing.

There were oil shows in the Lower Bucomazi and the Chela formations, and log analysis indicated oil pay in the secondary target Chela formation sands.

Although the well bore was not ideally situated to encounter the thickest part of the Chela sands, an abbreviated test was carried out to determine the reservoir characteristic.

The data will be incorporated into the area evaluation to determine if there is a possibility of a commercial accumulation of hydrocarbons updip of the current well, the company said.

Currently preparations are being made to plug and abandon the well and subsequently move to the Bayingu-1 exploration well, previously designated the ‘H’ prospect located in the southern portion of the Nganzi Block.
