ENI Calls For Geophysical Survey Services In Nigeria




Nigerian Agip Exploration Limited (NAE) intends to put in place a global tender for the PROVISION OF GEOPHYSICAL & GEOMORPHOLOGICAL SURVEY SERVICES IN NAE OFFSHORE ACREAGES

The proposed contrast shall have duration of two (2) years plus one optional year effective from the date of award of the contrast for the service.

The geophysical & geomophological sites survey contrast, shall be executed on call-out basis as and when needed.


The scope of the contrast shell cover the following without limitation:


• Field area to be surveyed will be in water depths varying from 60 m to 2,l00m The survey shall cover any significant area that will be utilized during the structure

lifecycle: as a minimum, survey area shall be as indicated in the following table.


CONTRACTOR will have the responsibility to survey a larger area if so requested:


SURVEY                                     SURVEY

Mobile drilling rig jack-up     2×2 km area                                 500×500 m area

Platform fixed platform


Semisub / drilling ship and     3 x 3 km area, or larger to          Usually not necessary

FPSO                                       encompass the maximum

Expected anchor spread


• The purpose of the survey is to carry out a thorough investigation of the seabed

features with sufficient penetration end resolution to gather data that are essential for the emplacement of structures dedicated to hydrocarbon exploration and exploitation.


The scope of work shall include gathering detailed data about the        (high degree of precision), morphology and consistency of the seabed, presence of obstacle (wrecks, war surplus, etc) or pre-existent structures (pipelines, cables, etc) on the sea bottom, stratigraphy and lithology of shallow formations (few tens of meters below seabed), mechanical characteristics of the seabed, presence of shallow gas pockets and possible occurrence of oceanic Poseidon beds and banks and their relative density on the proposed platform/rig location or pipeline routes.

• Provide reconnaissence evaluation of seabed morphology, including topographic features (local steep slopes, channels, hills/dunes), unevenness (scour zones, sand apples, sand waves/dunes, seabed vegetation), geohazards (faults, landslide, rock outcrops/ridges, pockmarks/gas seepage, mud volcanoes, boulders. shallow gas, liquefaction potential induced by earthquakes or waves, hydrate zones), man—made hazards (ship-wrecks, well heads, flow lines, power cables and communication cables, debris, unexploded ordnances, chemical dump sites), Geophysical & Geomorphdogical surveys include (Survey maybe done by AUV):

• Real tine DGPS positioning system and navigation equipment for surface positioning of the mother vessel:

• DGPS and high precision acoustic positioning, inertial navigation and Doppler velocity

speed log to provide the AUV position (in case the latter system is adopted):

• water column acoustic velocity measurement system;

• bathymetry with multi and single bean swath echo sounder;

• sea bed imaging with high resolution dual-frequency side scan sonar;

• high resolution chip sub bottom profiler,

• magnetometer survey,

• conductivity, temperature, depth (CTP) sensor,

• deep stratigraphy imaging by means of high resolution multichannel survey with acoustic

source arid streamer;

• seabed sampling with gravity sampler, vibrocorer, piston sampler;

• classification and testing of soil samples etc;

The survey shall be conducted in two stages:

– First general stage, where the specified area is covered with low resolution and detail, including multi bean echosounder, side scan sonar, sub-bottom profile arid a 2-D high resolution seismic.  This survey shall be carried out on a line spacing suitable to ensure a survey coverage and data quality adequate for engineering and construction activities. Primary tracklines shall be spaced maximum 150 to 200m and line spacing suitable to ensure to 100% coverage of the Scan, Sonar with a proper overlap between adjoining line.

– Second detailed stage, where the above measurements are repeated with largely greater

detail and resolution, across a limited area pertaining to the project structures and devices, with in addition magnetometer. This detailed survey shall be conducted in the specified areas of I x 1 km.
