Processing of seismic data land/marine 2D, 3D and/or 4D

Korte beschrijving

Energie Beheer Nederland (‘EBN’) is a state-owned company that operates under the supervision of the Dutch Ministry of Climate Policy and Green Growth (KGG). EBN uses its knowledge and experience in the area of the subsurface, the oil and gas sector and long-term, capital-intensive projects for a reliable and future-proof supply of energy. Part of this role is carrying out activities for the exploration of the subsurface to identify possibilities to develop geothermal, natural gas and oil exploitation projects.
EBN wants to make a constructive contribution to the acceleration of the energy transition. Under the heading ‘Energising the transition’ EBN is now focusing on: “the sustainable and safe development of natural gas and oil reserves in the Netherlands, safe and sustainable reuse and decommissioning of disused infrastructure, and the use of sustainable forms of energy from the subsurface such as geothermal energy.” 

EBN aims to have a leading role in realizing the energy transition and ensuring that the energy demand of the Netherlands can be met in a sustainable, stable, and affordable way. Part of this role is carrying out activities for the exploration of the subsurface to identify possibilities to develop geothermal projects. 

In this context, EBN is planning to process and reprocess seismic data both onshore (for geothermal applications) and offshore (for natural gas and oil exploration projects).

With this RFQ, EBN seeks to identify technically capable seismic processing CONTRACTORS through a pre-qualification tender. Any CONTRACTOR that passes this pre-qualification will join a list of APPROVED SUPPLIERS and EBN aims to sign a FRAMEWORK AGREEMENT with each of these CONTRACTORS with a zero-hour work commitment. 

If EBN requires seismic processing services, all APPROVED SUPPLIERS will then be invited in a “mini-tender” to bid on a specific work package for either processing newly acquired 2D or 3D seismic data or the reprocessing of vintage 2D or 3D seismic data.

EBN has decided to divide the seismic processing services into the following four (4) separate lots:
1)    Seismic processing CONTRACTORS selected for onshore 2D processing services;
2)    Seismic processing CONTRACTORS selected for onshore 3D processing services;
3)    Seismic processing CONTRACTORS selected for marine 2D, 3D & 4D processing services for towed streamer acquisition; 
4)    Seismic processing CONTRACTORS selected for marine 2D, 3D or 4D processing services for Ocean Bottom Cable (OBC) and/or Ocean Bottom Node (OBN) acquisition.

The purpose of this separation is to allow seismic processing service providers with niche capabilities to compete in their area of expertise, without being penalized for not being able to execute e.g. large volume and/or complex 3D processing projects. As such CONTRACTORS may participate in one, two, three or all four lots.

The purpose of this invitation to tender is:
To provide potential Companies with information about the contract and the tendering procedure;
To make clear the manner in which the potential Company can submit its Offer, what the tender requirements are, and when which details must be submitted;
To provide insight into the manner in which the tendering process takes place, the manner in which the submissions are evaluated and how the rest of the procedure works.

Beschrijving van de aanbesteding

The scope for potential 2D seismic processing comprises the processing of newly acquired 2D seismic data, either regional long offset lines or short local 2D lines over possible SCAN research well locations as well as the reprocessing of vintage 2D seismic data, either explosives or vibroseis acquisition, mainly from the early 1970s to the late 1990s. Whilst the majority of 2D seismic data processing under this FRAMEWORK AGREEMENT will likely be for the SCAN 4 project, COMPANY may, in addition, also elect to use the FRAMEWORK AGREEMENT to (re)process 2D seismic data on behalf of other stakeholders in the Netherlands. In such case, COMPANY will retain all project management responsibilities, and the execution of the seismic (re)processing shall be done as if the data were SCAN 4 data, with COMPANY remaining the sole contact for the CONTRACTOR.
If possible, the newly acquired data will be acquired with 5m receivers spacing, 60m shot spacing and with a maximum off set of 7000m using a split-spread geophone layout, giving a nominal fold of 116.
For the reprocessing, the nominal fold may vary from 6 to 120, and the maximum offsets usually range from 2km to 4km. Often identing of the raw field data may be required and the input data might be digital as ACSCII files or scanned paper observer logs or coordinate data.

Whilst the majority of 3D seismic data processing under this FRAMEWORK AGREEMENT will be for the SCAN 4 project, COMPANY may, in addition, also elect to use the FRAMEWORK AGREEMENT to (re)process 3D seismic data on behalf of other stakeholders in the Netherlands.

In such case, COMPANY will retain all project management responsibilities, and the execution of the seismic (re)processing shall be done as if the data were SCAN 4 data, with COMPANY (EBN) remaining the sole contact for the CONTRACTOR.

The acquisition parameters for the 3D acquisition(s) are not decided yet, and may vary between surveys, based on the geological targets. Regarding seismic sources, a mix of explosives and vibroseis is anticipated, with infill by airguns, if and when significant water crossings are required.

Beschrijving van de aanbesteding

As the seismic processing FRAMEWORK AGREEMENT is meant to cover all current and possible future seismic processing needs of EBN, may it be for CCUS or O&G exploration activities, this lot has been defined for the processing of any conventional tower streamer seismic data, either for the processing of newly acquired data or for the reprocessing of vintage data. At the writing of this tender, the scope for such seismic (re)processing is undefined.

Beschrijving van de aanbesteding

In addition to the (re)processing of 2D, 3D or 4D marine surveys acquired with towed streamer acquisition systems, the processing FRAMEWORK AGREEMENT shall also cover the processing of offshore 2D, 3D or 4D seismic data acquired with Ocean Bottom Cable (OBC) or Ocean Bottom Node (OBN) acquisition systems. At the writing of this tender, the scope for such seismic (re)processing is undefined.
