Overview• Niger Delta Well 10 • Logs run by Schlumberger• Country: Nigeria• Location: Niger Delta• Niger Delta Details: • Delta of Niger River at the Gulf of

Guinea of the Atlantic Ocean in Nigeria.

• Area= 70,000 km^2• Located within the Pan African

mobile belt in the West African and Congo border.

• West Africa’s biggest producer of petroleum

Geologic Structure• Geologic structure dominated by crystalline and sedimentary

rocks.• Primary seal rock is in the interbedded shale• The structure is primarily made of of rollvoer anticline, collapsed

crests, and clay filled channels.• Lithology

• Source rocks are marine shale with land plant material• The reservoir rocks are predominantly sandstones

Header• Bit size: 3.875 in• Drilling fluid: Salt base, brine• Source of Original Data:

• Caliper log• Gamma Ray Log• Spontaneous Potential Log• ILD Log• SN log• Neutron Log• Density Log

• Calculated Results:• Volume of Shale Estimate• Saturation of Water & movable Oil• Effective porosity

• Dominant lithology: shale & sandstone

• Appears to have good sandstone data.

• However, from the saturation data, it is apparent that all the pore space is occupied by

• Unfortunately, there is no oil in this

Interval A

• From the GR & SP Log.• Dominant lithology: Sandstone & Shale

• From the Resistivity Log,• There is oil in the sandstone interval.

• The effective porosity desirable in this interval.

• There are two small intervals which have oil potential.

• Depth: 9850-10000 ft (where there is oil contact)

• Rw can be calculated from the Hingle Plot

• By using the Simandoux method,

Sw from Rw can be estimated

Political Considerations Ecocide

Most natural gas in this area is immediately burned. largest single source of green house gas emissions on

the planet. More than 7000 spills between 1970 and 1990

Human Rights Violations Niger Delta region remains arguably the poorest and

least developed area in Nigeria. Energy availability is epileptic in a region that provides

one-fifth of the energy needs of the United States. Political Corruption

One of the worst in the word There is significant corruption in the

underdevelopment of the Niger Delta Nigeria with the lowest per capita oil export earning

put at $212 per person in 2004

Financial Considerations About 80 per cent of Nigeria's oil and natural gas revenues

accrue to one per cent of the country's population. The other 99 per cent of the population receive the remaining 20

per cent of the oil and gas revenues Nigeria has the lowest per capita oil export earning put at $212

per person in 2004 Nigeria had an estimated $107 billion of its private wealth held

abroad Nigerians excluded from the profits of the oil wealth, most of the

wealth has not been invested within the country, contributing to most Nigerians living below the poverty line.

Conclusion Would we recommend the well?

No Not enough oil and gas Location
