Nikel2

Nikel2 is new expro gas company dedicated to non conventional gas resources that is a subsidiary of GEOTECH D group. Resources of this latter are including:

- Oil/gas and Mining division with assets in Canada, Australia and Africa.
Versus funded capex, the exploration programs of this group are largely successfull due to a permanent low cost approach on opex. Thanks to a large experience in geoscience supported by geoscientists of TelesioGalillei academy.

- Gas fields: Wharfresources plc, Domepetroleum, Phoenix, Allied oil, Jurassica …
Wharfresources is starting the first gas processing line of its gas processing facilities and pipelines from the 1st Gingin well (ep389) is part of JV onEP389 that discovers a conventional and huge shale gas field 37TCF certified - min 60TCF expected that makes 72Bus for Wharfresources.

- Mining assets: significant Australian resources of Yellowenergy, Allied gold, DNIMines, DNIMetal in Canada … are Uranium, Thorium, Gold, Silver (see ex: websites:Yellow Energyplc.com).

Within our R&D team there are two delivery arms:

Exploration consists of both Generative Exploration and Near Mine Exploration. Generative Exploration makes discoveries by leveraging our land position in the world's most prospective domains, while our Near Mine team supports the production and growth of those discoveries by providing reserve replacement and optimizing existing land position near our world-class districts.

Business Opportunity Delivery manages the projects from opportunity creation in the early stage studies through project development to ensure safe, on-time, on-budget and fit-for-purpose delivery into commercial production in partnership with our operating regions.

The delivery arms are supported by three enablement teams:

• Solutions & Innovation
• Business & Planning Services
• Value Assurance

These teams provide technical expertise, functional leadership, as well as project, portfolio and business planning across all stages of the pipeline, focusing on driving innovation and business effectiveness.

Business Introduction

Gas hydrate extraction addresses on exploration set of geographic/geochem techniques and hydrates extraction process(safe). Plus a gas valorisation scheme (gas exportation line or gas turbie/powergen facilities) are set on a float vessel.

MH Process Competitive

Competitive edge details of the process

Most of the work undertaken on this subject (R&D, offshore tests, ...) shows that many difficulties have to be overcome:

• Difficulties in HSE: risk of leakage or slippage or the collapse of the seabed sludge, conventional drilling may in fact create the sea floor collapse, no umbrella is provided to date to capture leakage or mitigate risk,
• Difficulties on present technology: horizontal drilling technology and traditional wells appear to provide limited effectiveness as a permeability and porosity away from the usual values in the fields known conventional homogeneous reservoir ...
• The economic difficulties: that are inherent in conventional technologies drilling submarine and underwater completion, appear very expensive (opex, capex), built in with high uncertainty on well operation efficiency (as these operations will be extremely multiplied) and very slow compared to interventions on the well of classical fields. For instance a subsea drilling can cost more than 250.000 usd/day, the drilling time can be increased more than 10, given the fragmentation of blocks of hydrate; which destroy economics of these oil expro tech.

We are implemented CT drilling processes, non cemented wells ; Management team as a long track of experience on the gas projects (chemical engineering modelling expert of MH extraction from mud, MH thermodynamics, chemical reaction modelling, mining works equipments), is getting and capitalizing all the practices, knowhow to develop the engineering basic design of such a MH subsea unit; also the MH technology, process installations will benefit from existing marine and subsea technologies , developped worlwide by oil companies; ex hydraulic or electrical instrum/control FMC technologies could becurrently applied.

Management team as a long track of experience on successful expro on gas projects (chemical engineering modelling expert of MH extraction from mud, MH thermodynamics, chemical reaction modelling, mining works equipments, CT oper), is getting and capitalizing all the expro practices, knowhow to develop the oper engineering design of such a MH subsea unit; also the MH technology, process installations will benefit from existing marine and subsea technologies, developped worlwide by oil companies; ex hydraulic or electrical instrum/control FMC technologies could be currently applied.

The idea of Nikel is a strategy of open pit mining under water, under an umbrella by deploying an innovative excavation system built in with a CT drilling process on the the seabed and the extraction of active MH, and preventing cave-ins and mudslides, the Nikel process does not use polluting products, and guarantees mitigation on leakages of gas and hydrates. The unit is supported by a moving ballast, and obviously has an adaptability and flexibility against the unpredictable basement of the seabed, including geotechnical characteristics of sea floor that vary randomly, with blocks of atomised MH. The special geophysics technology involved allows precise targeting of the area with acceptable feasibilty.

Furthermore, the simulations of the process will be based on numerous studies and research throughout the world (areas of physio-chemical, thermodynamic and engineering ...), the control and command of the installation will be carried out from a classic boat + a simple surface FPSO, industry ROV, underwater robotics is very mature and the knowledge and the operation attached to them.

This technology implements the optimum efficiency by recovering energy from CH4 in a turbo-expander at the surface, which then feeds a gas turbine driving an alternator. (Equipment located on the boat); This process offers a capex and opex at a much lower costing, to that of a traditional subsea rig and conventional oil production, drilling and production facilities for capex may represent respectively the sums of 370 MUSD and 400 MUSD average (capex + subsea system + FPSO surface vessel) this approach offers cost savings of about 8 times lower than a traditional capex.

Go to the market

Nikel MH Advanced MH mining process

Totally highly safe, flexible MH process providing actual risk management, risk mitigation

Perfect environmental loss prevention

On the top of this high return, quick high reserve value far lower opex and capex versus oil oiltech such as horizontal well.

HSE benefits of MH

• Loss prevention guidelines

Large coverage for CH4 leaks under the large bell around the drilling machines ; all leaks easy mitigation and collection :
- Option A: should a big leak causing overload for the riser line production line, the pressure safety valves open on the separated flare line up to the surface. Whenever that line is not that sufficient a special blowdown drum will be opened and receives a large sudden CH4 volume before flowing to the flare line.
- Option B: most of the time, there is no collapse risk and the normal line contains the leaks.

Environmental issues

- On sea bottom, no chemical product injected, just CAOH that is inert ; no bentonic effect apart from mechanical move of the mud (fermentation, bacteria not significantly disturbed).
- No pollution risk.
