Time Paper # Presentation
0830-0900 190726 Rigorous Carbonate and Sulphide Scale Predictions: What Really Matters? G. Verri Ness, K.S. Sorbie, Heriot-Watt University
09:00 - 10:30
01T  Sulphide Scale Formation and Control
Session Chairpersons Caroline Simpson - Scaled Solutions Limited, Helen Williams - Nalco Champion, An Ecolab Company
Sulphide scales are an ever increasing challenge in the oil and gas production, with some more challenging than others to mitigate with chemicals. In addition, removal of sulphide scales can be extremely difficult, and as such there is a real need for industry focus for new understanding and technologies in this area. It is recognised that there is a knowledge gap in comparison to the more conventional scales, in the understanding of the scale formation, deposition and mitigation aspects. This session explores advancements made in the understanding of sulphide scale precipitation, deposition and mitigation, as well as chemical development methods, and the effect of testing in multiphase conditions and the potential of surface coatings in combating adhesion of scale.

03T  Developments in Scale Predictions
Session Chairpersons Hua Guan - OneSubsea LLC, Marija Kilibarda - Aker BP
This session gives an insight into the recent developments within scale predictions. Scale predictions are important tools to more accurately evaluate the scaling risk, design scale inhibitor treatments, and predict fresh water breakthrough. It is an essential tool to handle scale issues in increasingly harsher environments, such as ultra-high temperature, pressure and complex ion conditions. Challenges associated with the impact of very high calcium concentrations on sulphate scale predictions at high temperature is one of the focuses of this session; in addition, there will be an interesting presentation regarding the kinetic effects into the thermodynamic modelling of CaCO3 scale.

04T  Produced Water Sample Handling and Analysis Methods
Session Chairpersons Stephen Mark Heath - Baker Hughes, a GE company, Eyvind Sørhaug - Repsol Exploration Norge AS
To prevent scale formation and deposition in oil fields reliably and cost efficiently, it is imperative to know the correct water chemistry throughout the production system and the level of protection provided by scale inhibitors used in scale inhibitor squeeze treatments. This session addresses these issues by presenting improved as well as new methods for analysing scale inhibitors returning from scale inhibitor treatments more accurately, a new methodology for determining formation water compositions contaminated with drilling mud filtrate and a review of sample preservation techniques.

Session Chairpersons Stephan Tobias Hatscher - Wintershall Holding GmbH, Myles Martin Jordan - Nalco Champion, An Ecolab Company
unconventional onshore hydrocarbon wells. Silicates as scaling species have entered our perception through enhanced oil recovery techniques, such as alkaline as well as steam flooding. With our awareness raised, both scale types are identified as flow assurance challenges that require effective control options. This session will contain presentations on practical experiences, and laboratory testing of chemicals as well as some fundamental insights into the formation/control of exotic scales. There will be operational case studies on inhibitor applications, as well as new laboratory methodologies to evaluate scale inhibition and understand the scaling process for those unconventional scales.

06T  Scale Management Methods
Session Chairpersons Ross Andrew McCartney - Oilfield Water Services Limited, Olav Martin Selle - Statoil ASA
In this session, a broad range of scale management topics will be presented. The first covers the laboratory work undertaken to qualify a scale inhibitor to prevent scale formation when an operator had to change from low sulphate seawater (LSSW) mixed with produced water (PW) for injection source to a blend of LSSW/PW and seawater (SW). The second summarises an operator's successful efforts to produce more water from their sulphate-reduction units, whilst optimising the quantity and type of scale inhibitors used (with a priority given to green chemicals). Finally, a comprehensive review of non-chemical methods for downhole scale control will be presented, including how they can minimise or alleviate the need for downhole chemical treatments.

08T  Scale Management in Carbonate Reservoirs and MEG Regeneration Systems
Session Chairpersons Salima Baraka-Lokmane - Total E&P, Amy T. Kan - Rice University
In this session the kinetics of dissolution and precipitation of calcium carbonate in MEG systems are investigated, particularly the determination of crystal growth and agglomeration rates of carbonates in different compositions of the MEG/water mixture. The topic of extending the squeeze life time is presented, the strategy for improvement of adsorption of scale inhibitors onto the carbonate rock is presented. Interactions between scale inhibitors are examined. Water injection is commonly used in oil fields for pressure support and productivity enhancement. The traditional thermodynamics approach for scale prediction only provides precipitation potential at different mixing ratios. In this session a reservoir reactive transport modelling of carbonate reservoir that predicts better the time-dependent mineral scales formation is presented.
