Marine gravity and magnetic data will be recorded in conjunction with the seismic survey. GPS navigation will be acquired at 1 second or more frequent intervals. Measurements will include x, y, z, vertical velocity, x-horizontal velocity, and y-horizontal velocity. GPS navigation will not be decimated coarser than 1 second. The gravity meter, magnetometer, and fathometer should be recording continuously from entry into Guinean waters until exiting Guinean waters. Efforts will be made to obtain tie lines during times of seismic repairs, weather downtime, or other periods when the vessel is able to transit the survey area obliquely to the seismic sail line direction. Magnetic diurnal reference data will be obtained from an onshore Magnetic Observatory. Processing will include:

b) For two adjacent depth sensors or more on the active streamer the following tolerance apply:

± 1.0m from the target depth for any 32 consecutive shots, or for 10% of the total number of shots acquired in one sail line sequence.

Depending on the results after QC processing, it may be possible to edit only the affected trace range. Data from the affected traces should be edited after pre-processing.

For multi-streamer operations, average noise levels on any streamer shall not exceed the average noise on any other streamer by more than 15%.

4 2 1

Bad Trace Definitions

•

•

•

Streamer noise exceeds the limits defined in Section 4.2.2.

•

Trace is dead, spiking or wild.

•

Signal is distorted or out of phase by more than 30 degrees or 1ms.

4.2.2

Streamer Noise Definitions

Streamer noise will be given in microbars RMS and measured over the full recording cycle with recording filters and with the streamer at the specified tow depth and in Dovetail mode.

Ambient noise levels shall not exceed:

•

12 (µbar for first three groups on streamer

•

10 (µbar at groups near birds, acoustic units and last group

•

7 (µbar elsewhere noise to be measured from 8 seconds of data and through 4 to 125 Hz filters.

The following guidelines may be used for determination of acceptable levels of coherent noise and swell noise but will depend on geophysical objectives. Whenever possible the use of onboard processing/QC systems should be used to further evaluate the effects of noise on the data. In any case the final decision will rest with COMPANY in consultation with its representative.

Swell noise

Noise of up to 25 microbars can be tolerated if appearing on less than 10% of the traces in shot records on any line and is less than 2 seconds in duration.

Acceptable levels of swell noise should be decided after a review of the QC processing and, where required, evaluation following swell noise suppression and other noise rejection processes. Evaluation shall be based on the analysis of signal-to-noise requirements at target level by on-board QC processing, such to be judged using on-board processed shot records, difference records, QC-stacks, QC-migrated stacks and RMS cubes as defined in 2.14. The analysis will be performed when operating conditions are becoming critical. The results will be sent in electronic for m to COMPANY'S Technical Dept. headquarters, for their evaluation.

Further if, in the opinion of the COMPANY'S representative, data acquired at the nominal streamer depth is likely to be rejected due to excess noise then the streamer depth shall be increased by ▇ ▇ subject to approval of COMPANY' S Technical Dept. headquarters. In this case the acceptance criteria above shall continue to apply. All logs will clearly highlight any lines acquired with deeper streamers.

In case of dispute, COMPAN Y reserves the right to ▇▇▇▇ and treat as bad any traces if the unfiltered RMS noise level averaged over one sequence, exceeds 7 micro bars RMS measured through an 4 Hz, 18 dB/octave low cut filter.

Acceptance of data to be analyzed following result of onboard QC processing.

Coherent noise

Coherent noise shall be assessed according to the following:

•

Amplitude of the interfering signal.

•

Duration of the noise.

•

Repetition and synchronization of the interference.

•

Moveout of the interference.

Constant interference up toµ 10 microbars will only be tolerated up to a maximum duration of 4 seconds.

The onboard processing system will be used to quantify the effects of interference on the data giving due consideration to geophysical objectives on the 0 - 10.0 sec time window.

The following general rule is intended as a guideline only which may be used for determination of appropriate levels of coherent noise by the onboard QC processing system. RMS levels higher than the values in the table below may be acceptable based on that evaluation.

As a general rule, coherent noise should not exceed the following limits for 12.5 meter group.

Noise coming from astern of the streamer
Moveout	Max. Noise µbar RMS
More than 300 ms/Km	28 µbar
150-300 ms/Km	14 µbar
0-150 ms/Km	6 µbar

Noise coming from ahead of the streamer
Moveout	Max. Noise µbar RMS
More than 500 ms/Km	28 µbar
400-500 ms/Km	14 µbar
0-400 ms/Km	6 µbar

Note: Coherent noise sources should be identified and logged. Action should be taken to ensure shot to hot timing differentials of the noise exceed 500msec.

Noise coming from the beam (or side) can be particularly harmful and difficult to deal with in processing. In general terms only low levels of interference from the beam may be tolerated for short durations within a record. In these situations, the use of onboard QC processing systems are necessary, to fully evaluate the effects on the data.

4.2.3

Streamer Feathering

Streamer feathering angles may be computed from compass data or from tail buoy radio/RGPS data.

Maximum streamer feathering shall be:

For 2D tie lines: <5 degrees

In severe tidal regimes or in unpredictable currents COMPANY representative may relax the above limits.

CONTRACTOR shall pay due attention to the effects of tidal streams and/or currents on streamer feathering and shall make every effort to match adjacent line feathering angles to minimize infill.

CONTRACTOR shall use all available published information, including any information provided by COMPANY, to predict the feathering.

4.3	Streamers QC Checks and Test

Trace polarity shall be in accordance with SEG convention namely a compression wave shall produce a negative number on tape, downward deflection on camera monitor and a white trough on the trace recorder.

Streamer sensitivity, electrical resistance, crossfeed and insulation will be verified at the beginning of each line or at any time if requested by COMPANY representative. Streamer sensitivity shall be evaluated from a series of fixed gain displays.

Streamer noise tests shall be undertaken on the run in and at the end of every line and recorded on the production tape. A reference signal shall also be recorded on an auxiliary channel. During noise tests:

o The vessel shall be at survey speed (nominally 4.0-5.0 knots),

o The recording settings will be as per the specified acquisition parameters, o The streamer will be at the specified depth.

The source to near trace in-line offset will be verified at the start of each line by using water- break phones or acoustic devices or any other reliable method. A change in linear source to near trace offset of more than half group length from the mean shall be investigated and remedied.

4.4	Streamers Spares
