This tender seeks to engage experts to simulate CO2 injection and analyse related pressure changes and formation fluid movements at existing well sites within the UKCS. The procurement stage is currently active with an open procedure, and the tender period will close on 29 November 2024 at 16:00 GMT. The contract is expected to start on 16 December 2024 and will conclude on 31 March 2025. The project budget ranges between GBP 80,000 and GBP 120,000. The primary location for the project is the United Kingdom. This tender represents a significant business growth opportunity for companies specialising in subsurface modelling and CO2 injection analysis. Ideal participants include SMEs with expertise in simulating geological and hydrological scenarios, particularly within the context of CO2 injection and formation fluid dynamics. Firms adept in assessing environmental impacts and creating detailed pressure change models could find this tender particularly aligned with their skill sets. By providing critical insights into formation fluid movements and potential environmental impacts, these businesses can play a pivotal role in advancing CO2 injection safety and efficacy, thereby contributing to the energy sector's sustainability efforts. ## Notice This project aims to utilise subsurface modelling in an appropriate part of the UKCS, to simulate CO2 injection and the related impact of pressure changes and formation fluid movement at existing wells. Identifying the magnitude and timing of pressure changes in relation to a range of well situations (e.g. open/closed to rock at different stratigraphic levels) is a key measure of success. Additionally, in the event that modelling suggests plausible scenarios where formation fluid may be expected to escape to the water column, the NSTA are interested in quantifying the potential impacts. For example, the duration, distribution and magnitude of salinity changes on different scales. In detail, the NSTA expects that any proposal would incorporate, but not be limited to consideration of: * pressure changes associated with CO2 injection on a variety of scales at existing well locations; * pressure changes, across multiple stratigraphic intervals, at the well locations and the timing over which they occur; * the relative susceptibility to fluid escape of wells based on 'typical' abandonment scenarios and their relationship to subsurface architecture (e.g. open to one penetrated interval, closed to another) and CO2 injection activity; * the volume of formation fluid that could enter a wellbore at different stratigraphic intervals as a result of CO2 injection; * impacts of formation fluid escape on the water column on a variety of scales; This project does not seek to explicitly model CO2 migration or any form of CO2 leakage but rather the pressure effects and movement of formation fluid in the context of existing wells as a consequence of CO2 injection. This project is a subsurface focussed objective rather than a well focus and should not enter into detailed well design or abandonment status. Additional information: The terms and conditions will be determined by the final bid price of the successul tender. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/4c7efe9e-0834-452b-8f85-51a0b5fc25b2 | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Open procedure (below threshold) | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 20 Nov 2024 | | Submission deadline | 29 Nov 2024 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 16 Dec 2024 - 31 Mar 2025 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £120,000 | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Active | | Lots status | Not specified | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | OIL AND GAS AUTHORITY | | Locality | LONDON | | Post town | Central London | | Postcode | WC1B 3HF | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI36 Camden | | Local authority | Camden | | Electoral ward | Bloomsbury | | Westminster constituency | Holborn and St Pancras | | Delivery location | Not specified | ## CPV Codes ### Divisions - 76 - Services related to the oil and gas industry ### Codes - 76100000 - Professional services for the gas industry - 76200000 - Professional services for the oil industry ## Release History - 20 Nov 2024 at 13:40 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/4c7efe9e-0834-452b-8f85-51a0b5fc25b2 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/4c7efe9e-0834-452b-8f85-51a0b5fc25b2 20th November 2024 - Opportunity notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/Attachment/f022bc6a-7ba0-4f64-b980-f0df91857c24 Terms and conditions below PS100,000 - https://www.contractsfinder.service.gov.uk/Notice/Attachment/ce29af7a-d9f6-4765-9718-890f2babf111 Terms and conditions above PS100,000 - https://www.contractsfinder.service.gov.uk/Notice/Attachment/01635d0d-f4ad-4d3f-96f4-18d0e6a8cd9d ITT document - description and application process ## Notice URLs - https://www.nstauthority.co.uk/ ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
