Mauritanian Drilling Update: Heron 1 (Block 20)
Australian based oil and gas exploration company Baraka Petroleum Limited (ASX: BKP) has
been provided with an update on the drilling of Heron-1 within Coastal Block 20 in Mauritania by
operator and joint venture partner CNPC International Mauritania Limited (CNPCIM).
This update is as follows:
The land-drilling rig ZJ50LDB operated by drilling operator GWDC (Great Wall Drilling Company)
has continued drilling the CNPCIM operated Heron-1 exploration well in coastal Block 20 onshore
Mauritania, West Africa (see Figure 1).
As at 2:00 pm (AWST) on the 1 January 2007, the operation was drilling ahead in 8 1/2 inch
hole at a depth of 3103 metres with no shows. Continued reduced penetration rate has been
due to the Operator attempting to reduce the deviation angle (angle from vertical) of the well.
Formation penetrated was claystones and some sandstones with occasional limestones.
The next zone of special interest is at approximately 3600 metres, however the entire section
from 2200 metres to the total depth of the well, at approximately 3,800 metres, has potential
reservoir seal pairs and occurs within closure of the Heron structure and therefore has the
potential to contain hydrocarbons.
The Total Depth (TD) of the Heron-1 well is proposed at 3800m with four casing strings planned.
Due to the slow penetration rate the well is expected to take longer than the three months
planned so far.
CNPCIM is a wholly owned subsidiary of CNPC International Limited (CNPCI) and is Operator of
Block 20 with 65% interest. Baraka Petroleum’s interest in Block 20 is 35%.
