08:30 - 09:00
01K  Keynote Session 1 Fleming Auditorium
Predicting the formation of pH-dependant scales such as carbonates and sulphides requires a full study of all hydrocarbon and aqueous phases present to determine the distribution and speciation of CO2 and H2S in the system. Several commercially available software packages combine PVT calculations with scale predictions but packages more targeted to aqueous systems have limited hydrocarbon capabilities. Likewise, PVT modelling software focusing on the hydrocarbon phase does not always fully model the aqueous phase or can only predict a limited number of scales/complexes. Moreover, within each software a large number of different Equations of State (EOS), activity models, parameters etc. which ultimately impact the final carbonate and sulphide scale prediction profile can be selected by the user. The results to be presented will show that despite the large number of modelling options available, there are two parameters that play a key role in pH-dependant scale predictions: partition coefficients of CO2 and H2S between gas, oil and water and the relative mole (and volume) distribution between each phase at selected temperature and pressure. The final scale prediction results can be accurate only when these values are accurate, irrespective of how they are obtained.

09:00 - 10:30
01T  Sulphide Scale Formation and Control Fleming Auditorium
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 Fleming Auditorium
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.

Session Chairpersons Stephen Mark Heath - Baker Hughes, a GE company, Eyvind Sorhaug - 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.

02K  Keynote Session 2 Fleming Auditorium
Produced water from the Bakken and Three Forks formation in the Williston Basin is notably high in total dissolved solids, which leads to many well maintenance issues related to halite scaling. Freshwater is widely used to prevent halite scaling; however, an efficient and practical halite scale management program is highly desirable to manage operation and maintenance costs. The programme includes identification of wells that need freshwater injection; optimisation of the fresh water volumes; minimising deferred oil production; and preventing other scales associated with the presence of fresh water in the wellbore. Developing a reliable scaling prediction model was challenging due to inconsistency of produced water composition of individual wells, limited reservoir fluid composition data and high sensitivity of halite scaling risk to slight changes of halite saturation index. The output of this study resulted in optimising both freshwater and chemical treatment programs to minimise halite scaling. Significant cost savings have been achieved from reduced freshwater usage, thereby resulting in lowered produced water disposal. Continuous freshwater injection systems were proven to actively control the ratio of freshwater to production water and achieve additional cost reductions.

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.

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 Fleming Auditorium
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.
