  • Production Volume:

+++ Description

  • The Nemba field, located in Area B of Block 0 approximately 37 miles (62 kilometers) west of the Malongo Terminal, is being developed through two production platforms, South and North Nemba.
  • Both platforms include gas compression facilities for gas conservation and secondary recovery through rich gas injection.
  • The North Nemba drilling program includes 12 wells, nine oil/condensate production wells and three gas injection wells
  • Early oil was produced using the [[[Jamestown FPSO]]], prior to installation of the permanent platforms

+++ Contractors

  • **FMC:**
    • Early Production System (EPS), including subsea trees, wellhead adapter spool assemblies, system integration testing, installation assistance, service and maintenance
    • Design and supply of permanent spread mooring system for installation on an early production system
  • **McDermott-ETPM:** Pipeline installation
  • **ETPM:** North Nemba Installation

+++ History

  • 1996 - Early oil production begins
  • 1998 - South Nemba comes on stream
  • 2001 - North Nemba comes on stream
  • 2010 - Alliance Engineering awarded South Nemba Auxiliary project

+++ Geology

  • The trapping mechanism is a south-plunging anticlinal horst surrounded on all sides by faults that are sealed vertically by fine-grained upper Cretaceous rocks and laterally by Tertiary shale. Numerous small faults occur within the structure.
  • A gas cap (up to 1,100 ft thick in the northernpart of the reservoir) overlies a 480-ft-thick oil column.
  • The Pinda formation in the field consists of a sequence of interbedded carbonate and clastic rocks that is more than 3,500 ft thick in the discovery well
