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 26 December 2006, the operation was drilling ahead in 8 1/2 inch
hole at a depth of 2955 metres with no shows. Since the last ASX release, a logging run to
surface to assess casing cement integrity, bit changes, reaming and reduced penetration rate
has temporarily slowed progress in the well. Formation penetrated is interbedded sandstones
and claystones 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.
The drilling of exploration well Heron-1 is expected to take approximately 3 months to complete
to a depth of 3,800m and will include four casing strings.
