Flow Assurance and Production Chemistry: Finding Integrated Solutions Across the Value Chain

20 – 21 November 2012

Dubai, UAE | Amwaj Rotana Hotel, Jumeirah Beach Residence

Techical Agenda

Session 1: Prevention and Remediation of Flow Assurance Issues Caused by Inorganic/Organic Scales, NORM and Corrosion

Session Chairs: Ahmed El Hage, ZADCO; Bader Al-Harbi, Saudi Aramco

Organic scales e.g. wax, asphaltene and inorganic scales such as calcium carbonate, barium sulphate and iron sulphide have been recognized as one of the most potential problems encountered in production wells. These scales can block the perforations, valves, tubing and surface facilities and subsequently reduce the production significantly. Additionally, NORM materials create HSE concerns during production, transport and decommissioning stages. This session intends to explore all aspects of these flow assurance issues from their formation/inhibition and damage mechanisms to prevention/remediation and stimulation techniques. We welcome presentations in the areas of innovative laboratory studies, the use of simulation tools and field case histories. There will be a break out session at the end of the presentations to give the attendees the opportunity to share and discuss a range of topics pertaining to inorganic and organic scales and the treatment of NORM.

Session 2: Flow Modeling and Network Analysis – Pursuing a Systematic Approach

Session Chairs: Sanjay Misra, ADCO; Ping Chen, Champion Technologies

Flow assurance for a field life cycle is very important considering variations in the production volumes and compositions in terms of water cut and GOR. Multi-phase flow modeling and network analysis provide essential tools for FFD and facility design. Nodal analysis provides accurate answers to our well productivity issues as well as field production optimisation. Robust correlations are essential to covering a full spectrum of flow variations and temperature regimes. Future bottlenecks can be anticipated and mitigating strategies can be planned. Deep sea developments have created a vistas flow assurance challenges in terms of unstable flow and hydrate formation. Accurate prediction of potential challenges becomes essential as tremendous capital costs are involved in such developments. Recent developments in understanding unstable flow behavior like slugging and well loading have provided renewed interest in the industry. Limits of the technology had confined us to application of wax and asphaltenes precipitation in flow modeling, but developments in depositional modeling of these species have unlocked a plethora of new interest. In this session, we will discuss sound concepts of tackling flow assurance challenges through well analysis, flow modeling, network analysis and multi-phase flow behavior.

Session 3: Advanced Laboratory and Modeling Techniques for Flow Assurance

Session Chairs: Dennis Naafs, Shell; Francisco Vargas, The Petroleum Institute; Martijn Huijgen, Champion Technologies

The increasing complexity of current flow assurance problems has motivated the development of novel experimental procedures and enhanced modeling methods with the intention of assessing, predicting and mitigating these problems.

This session will highlight recent advances in understanding the most common flow assurance problems in the region, new approaches to study, forecast and treat the formation of organic and inorganic deposits at different stages of the oil production, and developments in improved correlation between lab data and field results.

Experts from the industry and academia will discuss novel experimental and modeling methods available to manage these flow assurance problems.

Session 4: Innovative Technologies and Non-Conventional Solutions for Flow Assurance in Challenging Environments

Session Chairs: Solomon Lekia, Chevron; Daniel Merino, Repsol

Flow assurance challenges are common to all onshore/shallow water/deepwater fields. Over the years, numerous methods have been applied to tackle specific issues, such as heavy oil not flowing freely, organic/inorganic deposition, multiphase flow. Control and mitigation methods for flow assurance risks must be both cost-effective and practical, and standard technologies may become non-optimal solutions in many examples in extreme environments, etc. Innovative technologies (active heating, multiphase boosting, kinetic inhibition) and non-conventional methods for non-conventional problems are more and more common to find the optimal strategy to assure deliverability in extreme environmental conditions. 

Session 5: Online Production Monitoring Systems and Optimisation and Debottlenecking in Flow System

Session Chairs: Hua Guan, M-I Swaco; Morten Stenhaug, Schlumberger

This session intends to encourage the sharing of experiences and best practices in the areas of real time monitoring, data transfer, remote control, flow modeling and collaborative work environment (CWE) which has added new dimensions to optimization and debottlenecking of production systems. With the advancement in data acquisition, transmission and modeling fields are increasingly monitored online with help of smart wells, virtual metering, integrated production system modeling. Many advanced predictive tools facilitate diagnosing potential problems with early warnings so that proactive actions can be made such as re-routing of wells, changing operation parameters (e.g. pressure by adjusting production and injection rates); and opportunities for production optimization are identified. This session welcomes abstracts covering the development of technologies and field case histories on such advances addressing broader reservoir management and flow assurance issues.

Session 6: Chemical Treatment – Economical and Environmental Aspects

Session Chairs: Ardian Nengkoda, Petroleum Development Oman; Ghada Bassioni, The Petroleum Institute/Ain Shams University

Global oilfield chemical demand will rise 8.6 percent annually through 2014, driven by a recovery in the oil and gas industry (EOR and unconventional production) and higher oil and gas prices. Naturally, crude oil and gas are emerging from the well with a considerable range and variation of both physical properties and chemical constituents. Some organic and inorganic deposits, emulsions, corrosion products, however, have a negative impact on quality, safety, the ability of a well to continue to produce and the ability of the refinery to handle the output and consequently on cost. Application of chemicals becomes essential in terms of flow assurance risk mitigation. However:

  • chemicals can be rather expensive (OPEX),
  • applying chemicals can be labor intensive,
  • chemicals often have a negative impact on the environment when disposed.

Best practices suggest for these reasons that chemicals should only be applied as necessarily needed. Moreover, in order to select the most effective chemical, the problem at hand has to be fully identified. This session will discuss chemical treatment practices, case studies, the life cycle starting with laboratory testing through performance monitoring, effective treatment processes (dehydration, produced water treatment, reservoir souring mitigation) and compliance to the environment.
