Oryx Petroleum hits oil and gas offshore Congo (Brazzaville)

China National Offshore Oil Corporation (CNOOC) is the operator of the licence with 80 per cent interest and Oryx Petroleum has a 20 per cent participating and working interest.

In August 2013, drilling of the E-1 well reached a total depth of 2,497 metres using the Jasper Explorer Drillship in 550 metres of water 80km offshore Congo (Brazzaville), the Africa-focussed explorer said.

The E-1 well was reportedly targeting a deeper turbiditic Tertiary play similar to the play being exploited in fields adjacent to the Haute Mer A License area, such as the Total-operated Moho Bilondo producing field and the Chevron operated Block 14 in Angola.

According to the company, the E-1 well was drilled around 4.5km south-east of the Libonolo Marine-1 (LIBM-1) well, which was drilled in 1997 by Elf Congo. The LIBM-1 well resulted in a discovery in the N5 interval of the Tertiary Miocene. Excellent reservoir quality was encountered with heavy oil 14° API gravity present.

Based on preliminary logging and other data from the E-1 well, 30 metres of gross interval (20.3 metres net) of crude oil and 102 metres of gross interval (58.8 metres net) of natural gas were encountered in the N5 interval and 16 metres of gross interval (9.2 metres net) of crude oil were encountered in the N3 interval. Water was encountered in other secondary targeted intervals, it added.

Henry Legarre, CEO of Oryx Petroleum, said, “We are pleased with the testing of the Elephant discovery which will serve as a building block for our operations in Congo (Brazzaville). Overall the test results confirmed the previously announced discovery. Moreover, the three drill stem tests (DSTs) conducted confirmed the excellent reservoir properties of the sand channels as well as some of the fluid characteristics. We look forward to working with our partners to appraise the Elephant discovery and adding to our resource base in the Haute Mer A License area.”

Oryx Petroleum and CNOOC said that they will further analyse the test results and other data accumulated during the drilling of the E-1 exploration well and determine the next step.
