Session 1: Subsurface to Surface Collaborative Planning and Integration
One of the major challenges oil and gas operators face during field development is achieving sustainability which can be constrained by failure of engagement between two key expert constituencies: planners/designers and subsurface engineers. The subsurface uncertainties impact production system design which may lead to losing opportunities or being controlled by risks and ultimately impact asset net present value (NPV) for the operator and partners. For that, it is indispensably necessary to introduce collaborative planning and integration workflows to allow better production maximization plans and optimize designed surface system with accommodating capacity without trading off the asset economics. To achieve this, the requirements can be broadly summarized in three aspects. The first involves minimizing uncertainties in reservoir insight using new technologies and/or techniques. The second calls for integrating subsurface activities with multi-disciplinary production or injection system technologies, production process de-bottlenecking, backpressure reduction and other associated processes. The third considers digital oilfield approaches which integrate reservoir and production systems for continuous monitoring of asset performance and production optimization, control of wells and fields and assists in planning for short- and long-term production optimization actions. This session will focus on sharing new ideas and/or best practices which highlight
- The subsurface uncertainties challenges and mitigating solutions.
- The impact on surface design and production capacity.
- How the collaboration between both parties can help maximize asset NPV.
Session 2: Field Optimization Lessons Applied to Conventional and Unconventional Fields
More and more oil and gas organizations are looking into ways to better optimize their conventional and unconventional fields with the use of advanced technologies and workflows. Motivation has come from a multitude of industry examples with one of these being the success in improving recovery in unconventional fields and driving down extraction costs. Thus, the widespread interest in feasibility assessments of unconventional fields across the world. Field optimization lessons learned in the oil and gas industry come from the multi-process nature of the sector and highlight the value to drive operations efficiency, optimize production, and maximize hydrocarbon recovery, and expedite decision making. Other optimization opportunities come from mitigation of health, environmental and safety risks in all aspects of field development. In conventional field development, reservoir characterization through integrated approaches allows both geoscientist and engineers to apply their combined knowledge, collaborative efforts, and methodology integration to better optimize the development pathway. In unconventional fields, multidisciplinary teams of geoscientist and engineers tackle challenges related to both shale and tight sand plays development. The lessons learned from such integration in existing fields serve as an example to strive towards continued improvement. The second workshop session will discuss the various optimal development strategies applied in both conventional and unconventional fields. The session will discuss:
- Case studies where geoscience and engineering integration aided reservoir characterization and optimization of field production
- Lessons learned from unconventional field development in conventional fields
- Optimization workflows across both conventional and unconventional in mature fields
Session 3: Exploring New Fields versus Optimizing Existing Fields – A Cost Driven Discussion
The search for new resources is a crucial component of oil and gas companies. To investors and petro-field employees, the resource base of any entity defines its existential outlook and the stability of occupational opportunities. To highlight the significance of these efforts, a review of company disclosure reports is likely to encounter metrics such as reserve replacement ratios and prospective resources. The need to replenish resources has driven global exploration into harsher environments or where bringing products to the market is likely to take years if factors such as transportation costs and long periods of pre-production construction are considered. For years, financial firms and investors have also rewarded the petroleum industry for finding additional resources no matter the timeline of necessary assessments, production, and capital required. However, product volatility and concerns about the potential of stranded resources have of recent changed the valuation philosophy towards short term metrics such as cash flow, profitability, and resource accessibility. Thus, exploration in new areas is more justified if the risk-reward aligns with the aforementioned considerations. To ensure sustainable resource base growth, an opportunity also lies in existing fields where embarking on re-evaluation of bypassed pay with less costly techniques and deployment of technology to increase recovery are some of the options. Given that fossil fuels are likely to remain a considerable component of the global energy supply pie chart, there is need to consider all available opportunities for increasing resource bases, in new and existing fields, while adhering to the arising challenges and concerns. In this session, the following will be covered:
- Cases where exploration of new fields is pursued in light of current industry conditions.
- Special cases in which cost-effective techniques have been applied to assess by-passed pay.
- Case studies on increasing the value of existing fields through recovery enhancement and other means.
Session 4: Workflow and Technologies Advancement
Geophysics, geology, geochemistry, geomechanics, petrophysics and the family of engineering offer concepts that aid in reducing subsurface uncertainties and preparation of maps and reservoir models. Associated static and dynamic geo-data becomes crucial for reservoir management and field development. Integrating multidisciplinary teams and technologies facilitates the updating of workflows, thus, bridging geoscience and engineering, and enhancing inter-team communication and collaboration. Innovative technologies and strategies, in hardware and software forms, have historically come from oriented research and development (R&D) in the operator and technical vendor or been adopted from other industries. The new or improved approaches have enabled petro-technical professionals to make accurate reserve estimation, improve imaging of the subsurface and pores, enhance well performance and recovery, reduce operational footprints, and mitigate environmental, health and safety risks. The aforementioned have contributed towards the upstream industry’s synergy and resilience in a volatile market with more environmental concerns. This session will be a platform for demonstrating and discussing:
- Workflows and strategies that integrate multidisciplinary geoscience for reservoir and production engineering optimization.
- Geo-technology innovations and deployment in reservoir and fluid characterization, reservoir management, field development, and near-field discovery.
- Geostatistics, geological models, reservoir modelling and simulation
- Digital transformation and sustainability in oil and gas fields
