Deepwater drilling has always been viewed as technically challenging and warrants an extensive capital investment. Due to these two factors, many of the deepwater reserve potentials are being held up by operators. To unlock these massive potentials in deepwater areas, new and innovative ways to drill and complete the wells in a safe and cost-effective manner are needed.
This session will discuss and highlight current deepwater drilling best practices application as well as potential future innovations and enhancements, to enable continuous improvement in both exploration and development drilling execution. Ultimately, helping to maintain and drive enhanced deepwater project economics, whilst trying to reduce the development drilling carbon footprint.
Discussion topics may include:
- Deepwater narrow margin drilling challenges in both exploration and development including infill, focusing on progress made in deepwater Managed Pressure Drilling (MPD) / Pressurised Mud Cap Drilling (PMCD), and deepwater wellbore strengthening equipment, techniques and applications.
- Integrated disciplinary optimisation of well trajectory planning on challenging deepwater plays: What has been achieved and what is possible to produce the optimal development option?
- Deepwater geohazards management and regulations for safe operating distance (respud well distance).
- Deepwater rigs: Current fleet, future demand, equipment reliability, utilisation of working rigs/warm stacked/cold stacked rigs, whilst identifying and driving down carbon emissions.
- Deepwater development drilling and completion optimisation and best practices: Best use of rig innovations and new equipment including drilling and completion batching/well-sequencing optimisation, logistics, service supply, and Personnel on Board (POB) management.

Due to the nature of deepwater wells, large well spacing may be needed to reduce the high operating cost. This will lead to higher uncertainties in reservoir characterisation such as reservoir heterogeneity, reservoir compartmentalisation, pore pressure variation, and zone producibility. These subsurface uncertainties could potentially create problems before and during the production stage. Thus, this session will focus on formation evaluation for subsurface data gathering from the deepwater reservoir. Topics that will be discussed will include the following:
- What are the challenges that might exist before and during formation evaluation?
- How to plan for efficient and effective formation evaluation for the deepwater reservoir?
- What are the latest technologies?
- What are the best practices and lessons learnt on formation evaluation from existing deepwater wells?
- Application of Advanced Technology and Automated Processing Workflows to Unlock Full Potential in Deep-water Prospects in the Critical Hours by Chiara Cavalleri, Schlumberger
As the deepwater operation continues to grow, it is inevitable for operators to spend higher CAPEX to monetise the field. Investment may be critical in a marginal deepwater field or a more complex field environment.
This session will focus on completion design and optimisation efforts that can be replicated or improvised based on industry experience. This will include key drivers, best practices, lessons learnt, strategic approaches, challenges, and technologies. This session will also discuss some of the consideration points in deepwater completions and development as below:
- Deepwater Sandface Completion Design: Comparison of techniques, industry improvement, and challenges.
- Deepwater Open Hole Gravel Packing: Equipment advances, length limitations.
- Deepwater Upper Completions: Current and new technology/hardware
- Deepwater Development Drilling and Completion Optimisation: Batch operation, sequence optimisation, logistics management, and best practices for well suspension.
- Deepwater Trees: Horizontal vs Vertical, equipment reliability, and QA/QC.
- Best practices for Subsea Umbilicals, Risers & Flowlines (SURF)-rigs, Intervention Workover Control System (IWOCS), and Wellhead-XT interface for smoother operation.
- Deepwater intervention.

This session will cover topics on both topside and subsea facilities in deepwater production operations, which include a review of how to extract hydrocarbon in a deepwater reservoir from drilling and well unloading up to the production phase. Some of the key flow assurance challenges at the surface, for instance, hydrate formation, wax and scale deposition (including erosional and corrosion in the surface flowlines), as well as practical mitigation plans from wellbore to the hose facilities, would be discussed from the practical point of view. Additionally, this session will also dive deeper into how to optimise well performance to prolong plateau production.
Key discussion topics may include:
- Hydraulic fracture in low permeability reservoir offshore: Profitable or too early?
- Challenges of chemical EOR in deepwater.
- Flow assurance in deepwater development and production.
- In-situ hydrates dissociation risk in deepwater development: Lessons learnt and mitigation strategies.
- How to remedy the hydrate formation in deepwater fields.
- Best practices in direct well unloading to host facilities (FPSO or platform).
- Maximising well life and deliverability as well as intervention management.

Oil and gas development are moving further offshore and deeper underwater as energy companies and service partners seek sources of production in these remote areas. Due to the remoteness and challenging environment, the capital cost for deepwater projects is often very substantial, and the risks for oil companies grow exponentially. The main factor for a successful deepwater operation is the alignment of project goals, deliverables, and measurements of success. Deepwater development requires the incentive that these remote basins will hold significant deposits of recoverable hydrocarbon reserves to be profitable for development in a very high cost and technically challenging environment. Unfortunately, large reserves in deepwater play are getting lesser and a shift in approach is required to make deepwater projects an attractive investment in the current global energy mix.
The session will review and discuss how deepwater projects can become a viable investment through the following:
- Technology advancement and best practices in pushing the technical boundaries and sustaining the project competitive with lower development costs.
- Technology innovation in green energy solutions as the industry aims to achieve the net-zero emissions target.
- Field development optimisation through geological uncertainty and risk mitigations.
- Reducing the time from discovery to first hydrocarbon production while addressing Technical, Economical, Commercial, Organisational, Political-Societal (TECOP) challenges.
- Critical role in project economics as the industry grapples with rising costs throughout the life cycle of asset development and production.
- Talent and experience retention strategies throughout oil and gas cycles for both operators and service industry.
- Overcoming challenges in deepwater facilities decommissioning and abandonment.
- Realistic approaches to contract management, commercial rigour and cost control to commercialise a prospect.

Directly and indirectly, the oil and gas industry accounts for 42% of global carbon emissions. As the pressure to act on climate change builds, how can oil and gas companies use hydrogen and carbon capture and storage to help lower the emissions?
This session will discuss the existing and potential technologies that are crucial to achieving a low-carbon economy in deepwater offshore whilst providing an opportunity to share experiences and/or challenges implementing those technologies. In the long run, driving standardisation and innovative solutions for sustainable energy development in deepwater.
