Activity near LotshiSOCO,our neighbour to the north of Lotshi in the Nganzi block has started a 4 well drilling campaign not far from Lotshi.They will drill 2 wells offshore and 2 onshore wells.They will decide later this year if they will drill in Nganzi next year.
Republic of Congo
SOCO announces that the exploration well on the Lideka East Marine prospect, the LDKEM-1 well, spudded on 20th July 2013. The well will test the potential of a post-salt structure of the Sendji Formation in the Lower Congo Basin, offshore Pointe Noire, in the Marine XI license which is updip from the 2009 Lideka Marine-1 well where oil shows were observed. The Sendji Formation is in a four way structural dip closure at the well location. Additionally, the lower part of the Tchala Formation is in structural closure with a fault seal to the North and East, and LDKEM-1 will also be able to test the reservoir potential of the Lower Tchala.
The well is expected to take approx. 30-35 days to reach the target depth.
Republic of Angola (Cabinda)
Final preparations are underway at the Dinge 20-6 and Dinge 20-7 well locations prior to the commencement of the two well exploration programme. The first well is expected to spud by the end of July. The Dinge 20-6 well is planned to test the Vovo Sands in the pre-salt section onshore Cabinda North in the area of the Dinge discovery. The target sands were deposited in a lacustrine environment above the middle Bucomazi which is a world class source rock.
The sands were tested previously in the 1970s by three wells. A lack of seismic prevented a fuller evaluation of the reservoir heterogeneity issues. The current locations have been selected following a block wide seismic acquisition and evaluation campaign that was completed last year. The Vovo sands of the Dinge Field are in an equivalent stratigraphic position to the Mengo-Kundji-Bindi reservoirs of the Republic of Congo 17km NW and on trend.
