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 the 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 29 January 2007, the operation was drilling ahead in 8 1/2 inch hole at a depth of 3668 metres. Formation penetrated was largely interbedded claystones with
some sandstones and occasional limestones. Fluorescence has been observed in sandstone over a three metre interval between 3647 and 3650 metres. These shows are still above the second objective, the Aptian aged limestones and sandstones, the top of which is estimated to occur at approximately 3700 – 3800 metres.
The Total Depth (TD) of the Heron-1 well will be revised based upon the depth at which the Aptian is penetrated. Four casing strings are planned.
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%.
