Agenda | All times MYT (UTC+8)

With the industry facing challenges due to COVID-19 pandemic and low oil price, cost or value-driven solutions are required to ensure sustainability in project economics and effective management. The panelists will discuss the challenges faced by their organisations, and how they overcome the situation in achieving financial goals, as well as maximising recovery through integrated solutions and multi-disciplinary collaborations.

This session will focus on predicting the onset of rock failure leading to sand production; such as location, timing, volume, and rate of solids production over the well lifecycle. Conditions such as function of rock mechanical properties, grain size, geological stress, wellbore orientation, perforation geometry, flow rate, reservoir pressure, and water cut are the critical areas to be reviewed in this process. 

Predicting solids volumes and rates are still considered challenging, however, credible sand predictions are critical to provide valuable insights to completion and production engineers, to develop fit-for-purpose sand management and sand control strategies.

This session aims to discuss proven case studies from both clastics and carbonate reservoirs, the robustness and reliability of current analytical, and numerical geomechanical sand prediction methodologies.

This session encompasses methodologies, lessons learnt and best practices from evaluation of both successes and failures during completion installation and long-term production. The focus of this session will include downhole solids control applications in open hole and cased hole, such as standalone screen completions, gravel packs, high rate water pack, and frac-pack. The continuous improvement of solids management operations is rooted in the understanding of both installation and performance, which can only be achieved through detailed data analysis and evaluation.

The remedial of sand issues caused by primary sand control installation failure, or wells that are completed without sand control, is an inherent problem in the oil and gas industry. Effective solutions have been extremely limited and costly; however, when these solutions are applied correctly, it can optimise the cost, safeguard assets, and prolong field life. This session will uncover the common ‘myths’ surrounding remedial sand control, and discuss lessons learnt on proper technique selection and placement, mechanical vs. chemical solutions, novel technologies, and innovative approaches.

Traditionally, sand sampling revolves around spot sampling which poses several challenges such as HSE, transient nature of sand production, and risk of impairment to samples during the collection and processing stages. Sand monitoring, on the other hand, utilises manual, intrusive/non-intrusive methods, and interpretation of the data.

Prediction of sand count, erosion rate, and subsequent sand volume with respect to time-based machine learning can improve decision making in sand management, and proactively make corrective measurement for Loss of Primary Containment (LOPC) avoidance. With a single source of integrated database, this has become the new way of working in holistic sand management to accelerate analysis and design. This session focuses on the challenges surrounding hardware, data analysis, HSE of sand sampling and monitoring, and how digitalisation can improve the way to manage sand issues.   

The dynamic and transient nature of multi-phase flow is the primary cause of low solids removal efficiency using conventional methods. Hazardous contaminants, such as mercury or Naturally Occurring Radioactive Material (NORM) in reservoir fluids or gas, can complicate the handling process of solids removed. As this becomes a risk for operators, stringent procedures and novel solutions are necessary.

Surface handling, as an initial strategy or in the case of downhole control failure, requires an estimate of expected solids volume, transport, and deposition modelling while ensuring the erosional integrity of downhole/wellhead/choke/flowline components. Safe and environmentally sustainable solids disposal becomes the final link in the surface sand management chain. This session will focus on solids handling on the surface, which require holistic strategies of solids management.
