Baraka Petroleum Limited 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).
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.
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. 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.
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%.
