EXPRESSION OF INTEREST AND REQUEST FOR QUOTE (RFQ) FOR SUPPLY OF PROCESSING OF A 3D NODAL MARINE, TRANSITION ZONE AND LAND SEISMIC DATA SERVICES TO PANAFRICAN ENERGY TANZANIA LIMITED
1. Pan African Energy Tanzania Ltd. a Producer, Distributor and Marketer of Natural Gas from the Songo Songo gas field in Kilwa District, Lindi Region hereby invites potential bidders to express their interest and provide a quote for the supply of the following Services.
2.Processing of a 3D nodal marine, Transition Zone and Land seismic dataset of approx.180 full fold km2 to be acquired in 02/03 2022. Over the shallow marine part, a 4C OBN survey will be acquired using air gun sources. Over the land area a 3C land OBN survey will be acquired using vibrators as sources.
The processing of this survey requires a high level of technical expertise from the Bidder as various technical challenges will need to be addressed to deliver the best value for the COMPANY in a timely manner. For the Bidder, this project will be a unique opportunity to showcase their technical capabilities given the complexity of the acquisition and the processing challenges at hand. It is currently envisaged that the acquisition Contractor will commence mobilization in July with the aim to commence test shooting in August/September. The Bidder is expected to allocate resources to participate in the analysis of the line testing.
The scope of work can be summarized as follows:
1. Full processing of the 3D Land/Marine OBN survey from field tapes to final product.
2. Extensive data integrity check whilst acquisition is still in progress.
3. Produce a Fastrack 3D Pre STM volume, through an accelerated processing flow, based on a single component.
4. Produce a Final 3D Pre STM volume for initial interpretation use.
5. Produce a Final 3D PreSDM volume, both in time and depth suitable for further AVO work and rock/fluid analysis.
6. Produce a 3D fully anisotropic velocity model, calibrated to the available well tops and quality controlled against the available sonic logs and check shot data.
7. Produce a set of Radial and Transverse gathers, accompanied with a recommendation for further PS processing.
8. Establish seismic data processing workflows that will provide products with the phase and amplitude integrity assured.
9. QI/AVO/AVA study to identify fluid types and rock properties in the Songo Songo field.
10. The reprocessing of one legacy 2D line up to PreStack Time migration (line 78-10-89) is considered.
3. This call for Eol and signifies the start of an open, transparent and objective tender process.
4. The Potential Bidder should be a well-established and reputable company and shall indicate that it is willing, capable, experienced and competent in supplying the said Services preferably to the Oil & Gas Industries. Failure to clearly so indicate may result in disqualification.
