Data-Driven Production Optimisation (Part 1)
Session Chairpersons Pejman Shoeibi Omrani, TNO; Kees Veeken, Mature Gas Well Consultancy

Production from mature oil and gas wells due to complexities in operations and marginal operational benefits is challenging. Underperforming production can result by e.g. decline in reservoir pressure, liquid loading in gas wells, scaling and have a huge impact on the expected well deliverability and overall field performance.

Early prediction of production alterations and proactive actions to control or mitigate these issues is key for successful day to day operations. Additionally, considerable amounts of data is generated during the development, testing and operation of these assets which contains valuable information and insights. In the recent years, the application of machine learning, artificial intelligence and big data for extracting information and insights from the data (historical and real-time, structured and unstructured, etc.) received attentions in the oil and gas industry.

The goal of this session is to provide data-driven insights for monitoring, predictions and optimizing the production and performance of mature assets. The topics related to this session are (but not limited to):

  • Case studies, field cases, challenges, successes and failures
  • Digital Oil field and Real time Production Monitoring
  • Application of “Big Data”, artificial intelligence and machine learning
  • Descriptive, predictive and prescriptive analytics
  • Data mining and data-driven models
  • Hybrid analytics
  • Added value of data visualization

Chemicals in Production Optimisation (Part 1)
Session Chairpersons Bjoern Lause, Baker Hughes; Ricardo Gijbels, EBN

Towards the end of the life of a well/field, not only the production and lifting of water poses a problem. An increase of water might also mean a higher load of ions that could form scale like BaSO4, CaSO4, CaCO3 and cause medium to severe production problems from the reservoir near wellbore up to the X-mas tree.

The increase of liquids also increases the risk of corrosion throughout the well.

Moreover, at the decreasing reservoir pressure the evaporation of water in the gas phase increases and could result in Salt drop out near the wellbore that will hamper the gas stream.

This session is intended (but not limited) to share experiences and results of different mitigation measures for the three mentioned challenges; salt precipitation, various kinds of scale, and corrosion.

Also, we would like to discuss the interaction of the various mitigation methods, especially how these could adversely affect each other; e.g. foamers could wash corrosion inhibitors from the tubing surface. Since Production Optimization in mature gas assets requires integration of all parties and disciplines, we should ask ourselves how can we stimulate cross-discipline communication.

Late-life Production Optimisation
Session Chairpersons Robert Sutton, Consultant; Ewout Biezen, Shell; Wouter Botermans, B-PES Botermans Petroleum Engineering Services

Late life production challenges are encountered in every oil and gas field.  Wells and facilities optimized for early life performance may not perform adequately at reduced reservoir pressure, and increased water and gas fractions.  Operators rely on best practices for their geographic area as they are forced to seek cost effective solutions to solve these problems.  Topics for Session 3 include a discussion of techniques to enhance surface separator facilities and excellence in well-reservoir-facility management.  Moving downhole to the reservoir, mature assets often require stimulation treatments to remediate formation damage.  An integrated approach for remediation is presented. For gas wells, the accumulation of water in the bottom of the well is a source of productivity impairment and a cutting-edge, lab-scale model is presented to further the understanding of the phenomena.

Chemicals in Production Optimisation (Part 2)

Surfactants, also often referred to as foamers, are being increasingly used to optimize production in oil and gas assets. Most applications relate to improvements of outflow performance of gas wells by reducing the minimum velocity and rate at which liquids can be successfully produced to surface, thereby increasing the recovery factor of the field. Some emerging applications are instead found in gas lifted oil wells, whereby the efficiency of the gas lift system is enhanced by foam assisted lift. Promising results have been recorded in several assets, especially in those cases where wells flowing in slug regime could be stabilized. Finally, topside applications are also showing promising results, with foamers used to reduce hold-up in pipelines or act as flowing pigs.

This session will explore different applications of surfactants in both oil and gas assets, and for both downhole and topside cases.
