More than 50 Questions SurvOPT can answer for Energy Companies
Could you answer these questions before you start?
How much time, money and trouble would you save if you could?
PRE-BID...
Even if you only have a rough outline, SurvOPT can give you a realistic simulation in minutes.
We need to survey a particular polygon
What vessel and streamer configurations will be cost effective?
What’s the fastest way of acquiring this polygon?
How long will it take?
What’s the time and cost impact of changes in streamer length?
If we start on a particular date, when will it be completed?
To get the best prediction, we need to allow for weather standby, technical downtime, and infill...
How do different estimates for infill and lost time affect completion dates?
Will the project be complete within the weather window?
The survey area has four platforms and some shallows...
How much time will this add to the survey?
What’s my expected coverage?
How big will the undershoot program be?
Approximately how long will it take to do the undershoot program?
Maybe we should use a smaller spread to improve coverage and safety around the obstructions...
Will it save time?
Will it be cheaper?
Will it reduce the undershoot program?
Vessel rates are at an all time high...
What’s our cost estimate with a fixed day rate?
How about a per-kilometer rate?
How much if the production rate applies for the first 2 hours of line change, and then standby rate?
How much if Infill is $X/km, Prime is $Y/km, and line changes are paid at a flat rate?
POST BID...
Contractors have submitted a number of proposals…
Is each acquisition plan tailored efficiently to the survey?
Do the predicted durations accurately reflect the vessel performance and survey geometry?
If bids include an expected average line change duration, how was it calculated and is it accurate?
Now a vessel and configuration has been chosen...
Can the estimates be refined using production data from a previous survey with the same vessel and configuration?
Where’s the best area to start shooting?
When can we expect to get the first swathe off to processing?
Imaging considerations require a wide group of lines must be shot towards the north...
How does that affect the shooting plan?
Would a different plan now be more efficient?
Area A needs to be shot as a priority area before areas B and C...
When will the priority area be complete?
How much longer will the project take if a priority area is defined?
How much more will it cost?
If the priority area is inefficient to shoot, what minor changes would make it more efficient?
...and this group of lines all need to be shot in the same direction
What’s the most efficient way of incorporating that into the plan?
A new area may need to be added to the survey...
How much more will it cost?
What effect will it have on the shooting plan?
What’s the incremental cost per square km? Is it worth it?
I want to deadhead all these obstructed lines to improve coverage…
How much time will this add to the survey?
We’ve got an FPSO passing through during the 2nd week... we won’t be able to shoot within area G
How much (if at all) will this add to survey duration?
Is it worth paying a premium to get the FPSO to detour?
The survey area is subject to tidal currents...
Which swathes should we shoot at spring tide? What about neaps?
What happens if the start date changes?
How are currents going to affect my close passes?
How are currents going to affect my infill rates?
Should I shoot progressive infill?
Overlapping streamers would reduce infill, but will the cost be prohibitive?
