Compagnie Minère Congolaise - CoMiCo
The Central Basin – Cuvette Centrale
Exploration Challenges in a Frontier Basin
CoMiCo – Frontier Exploration Acreage
»Cuvette Centrale Basin
approximately 1.2M km2
»CoMiCo acreage across
three blocks: 146,000km2
»Direct frontage to the
River Congo within Block
1 – approx. 350km and
500km from Kinshasa
»Access across the entire
acreage by major
tributaries of the Congo
river:
Rivers - Busira, Momboyo,
Lulonga, Lopori, Lukenie,
Fimi
»Two large lakes within
acreage: Inongo and
Ntomba
Block 1 – Mbandaka
50,000km2
Block 2 – Lokoro
48,000km2
Block 3 – Busira
48,000km2
Field Exploration (and Development) – Transport Considerations
2011 Geological Fieldwork Campaign
» The November 2011 Field Campaign was a collaboration between CoMiCo,
the DRC Hydrocarbon Ministry and the RMCA of Belgium
» Principal purpose: revisit oil seep sites and new oil seep and geophysical
sample locations
» Secondary purpose: survey the river network, access to hinterland and
viability of marine operations
» Exploration and development potential of typical prospect;
Bokunga Prospect, Boende, River Tshuapa.
Desktop Exploration – Prospectivity of CoMiCo’s Acreage
»Lack of data – compilation of worlds most comprehensive data set
»Approximately 45% of land area has returned data
»Competent Persons Report by Netherland Sewell & Associates Inc., USA. (NSAi)
»Undiscovered Volumetric Potential Study by Rose & Associates LLP, USA. (R&A)
Findings NSAi R&A
Number of studied structures 20 leads 12-80 fields
Mean recoverable volume (BOE) 3.0 Bn 7.0 Bn
Mean discovery size (MMBOE) 150 155
Max. expected discovery size (MMBOE) 750 1,100
Scoping Economics & Feasibility Study by Moyes & Co., USA
Exploration Process
» Shoot additional Gravity and Magnetics grid
» Acquire Satellite Imagery and other reconnaissance data
» Use above data to determine where to acquire additional 2D seismic data
» Acquire additional 2D seismic data
» Mobilize and drill exploratory prospect(s)
» Core and test any significant shows
» Appraise discoveries with additional wells, including flow test and core
» Shoot 3D seismic over discovery(ies)
» Complete drilling appraisal program to prove OOIP and reserve range
» Initiate engineering studies for field development plan
AERIAL ACQUISITION
OFFICE BASED ANALYSIS
IN FIELD SEISMIC ACQUISITION
BARGE BASED OPERATIONS
Aerial and Seismic Challenges
AERIAL
» Despite airbourne restrictions aero-acquisition is possible
SEISMIC
» Seismic acquisition across harsh environment is industry standard
Barge Based Operations
» Traditional exploration clears camps on
or near rivers (left - drilling base
Solimēos Basin, Amazon, Brazil)
» In regions where security or resupply
are difficult operations have been self-
sufficient from single or multiple barges.
» Early exploration of the
Mississippi delta and US Gulf
coast was from barges.
» Modern operations in the Nigerian
Delta region or Amazon rainforest
are sophisticated
» Environment and Safety FIRST
Technology and Environmentally Driven
» Remote operations in river
environments require an entirely
marine based logistical support.
» Supply base in Kinshasa to deliver
exploration equipment, people, food
and all ancillary components by barge.
» The technology that allows for
small footprint operations is
principally directional drilling
» Further advances in ‘whilst drilling’
data collection and analysis
reduces space and time
constraints.
… and the development plan?
» CoMiCo’s development plan is reliant on marine based operations
» Export route will be by small pipeline to riverside terminal
» From riverside terminal dual push-barge to Kinshasa - 35,000 bbl capacity
» Riverside terminals in Block 1 and in Kinshasa - 10 day storage capacity
» Twin existing pipeline from Kinshasa to Muanda
