The NAPE 2014 Pre-Conference Field Trip was held Saturday 8 November, 2014
The Theme was HYROCARBON PROSPECTIVITY OF THE DAHOMEY BASIN FROM OUTCROP ANALOGUES
The attraction for hydrocarbon exploration in Nigeria was as a result of bitumen seepages and tarsand occurrences in parts of eastern Cretaceous Dahomey Basin. Exploration drilling commenced (1907-1914) with the drilling of the now famous NBC Wells and subsequent utilization of the bitumen in road surfacing around Agbabu, east of Lagos.
A conspiracy of events bordering on: poor knowledge of basin inception, stratigraphy, narrow architecture of basin shelf, inadequate technology for drilling in deep waters and the later finds of much easier reach hydrocarbons in the Tertiary Niger Delta Basin, combined to it being poorly explored till date.
Exploration effort has intensified (1990s – 2013) following the discovery of the Jubilee finds (Offshore Ghana). Thus, in the last 10years, some 15 Wells have been drilled in the Continental Shelf with varying degrees of success. The field trip is intended to revisit this history in line with current findings and successes.

(a) Tarsand sample (b) Tarsand binder pellet (10-30% bitumen) (c) sample of road produced from tarsand (d) Flowing bitumen under artisan pressure from the tarsand belt
To evaluate outcrop sections and relate them to the stratigraphic and structural evolution of the eastern Dahomey basin
To describe the petroleum system and provide highlights on its prospects
Discuss the utilization of the vast bitumen occurrences in eastern Dahomey basin
Demonstrate effective strategy for data gathering for meaningful future exploration in eastern Dahomey basin.
STRENGTH OF 2014 FIELD TRIP
Trip to be conducted by seasoned professionals in oil industry and the academia with several years of combined experience in active petroleum exploration in frontier and mature basins and in University professorship.
An excellent opportunity for Oil and Gas companies to train their next generation exploration leaders and position them to lead future evaluation of Cretaceous basins in Nigeria.
WHO TO ATTEND: Professionals in the Oil & Gas industry, Academics, Students and Others.
NAPE 2013 PRE-CONFERENCE FIELD TRIP
The NAPE 2013 Pre-Conference Field Trip was held on Saturday, November 9, 2013.
The Eastern Dahomey Basin, SW Nigeria.
The trip will take participants on a NW profile route from Lagos via Ewekoro, through to Abeokuta, a journey that will cross–cut the NE portion of outcropping sediments (Tertiary –Cretaceous) of the eastern Dahomey Basin unto the Pre-Cambrian Crystalline Basement rocks.
Among other things, the trip will unravel the geological events at play during the Tertiary, leading to carbonate sedimentation as against the Cretaceous events giving rise to clastic sedimentation and formation of a petroleum system in the same basin.
STRENGTH OF FIELD TRIP
The trip will be coordinated by experienced industry players and seasoned academia. It plans to be very exciting and will surpass previous trips in content and delivery. Participants will definitely have value for their money!

2. The Cement plant at Ewekoro and the associated Limestone Quarry
3. Sedimentary/ Basement contact
4. The Olumo Rock and Gardens
- Live experience of coastal Sedimentary processes
- Slave trade “Point-Of-No-Return” and the tomb of the Portuguese after whom the Lekki Peninsula took its name
- Revisit the exploration history of Nigeria and see the sites of early exploration activities including the Lekki Coreholes and Orimedu-1 well
