01  Keynote Session 1
Session Chairpersons Myles Martin Jordan - ChampionX
A Keynote presentation is selected by the conference committee as it is one of the highest rated abstracted submitted in the call for papers. In this keynote paper (SPE-209475) observation of magnesium rich calcite deposits occurring within subsurface safety valves (SSSV) and topside process vessels is discussed. The background to its occurrence in the North Sea and Caspian assets, challenges to normal operations and some of the chemical solutions evaluated to control fouling by this “pseudo scale” are presented.

Challenges in the industry constantly evolve driving the development of new technologies and evaluation methods. Operating conditions are becoming more challenging, e.g. HPHT deep sea, hard to inhibit sulphide scales, high shear systems that exacerbate scale formation. In this session there will be discussions that each field presents unique conditions creating a distinctive set of scaling challenges, the need to understand the scaling risks, develop robust control strategies to ensure the efficiency of any treatments is maximised. Consideration will be given to how advancements are essential to ensure that new chemicals perform effectively, are fit-for-purpose, can successfully be deployed and minimise their environmental impact.

05  Keynote Session 2
Session Chairpersons Myles Martin Jordan - ChampionX
A Keynote presentation is selected by the conference committee as it is one of the highest rated abstracted submitted in the call for papers. In this keynote paper (SPE-209496) the challenge of zinc sulphide scale control via squeeze treatment at high temperature is evaluated. A thermally stable polyaniline-co-polymer based scale inhibitor (PANI-Co-Polymer SI) has been developed which shows a low minimum inhibitor concentration (<5mg/l) to prevent zinc sulphide scale formation via nucleation inhibition/growth modification and has the potential properties to adsorb/desorb effectively onto a sandstone substrate.

07  Scale Control Lessons Learned and Case Studies Part 2
Session Chairpersons Stephan Tobias Hatscher - Wintershall DEA, Ross Andrew McCartney - Oilfield Water Services Limited
Field case studies are an excellent source of information on real-life scale issues. In this session, an example from the Oda Field will show how a predicted scale risk (calcium sulphate) did not materialise under production conditions. A case study from the North Sea will show how a non-THPS cleaning chemical package was developed and deployed to mitigate iron sulphide, barium sulphate and biomass deposition during produced water injection. Finally, a study from the Gulf of Guinea will show that on this field, treatment for calcium carbonate, barium sulphate and calcium sulphate scale had to be adapted for individual wells.

09  Scale Treatment Design Optimisation
Session Chairpersons Gill Ross - Chrysaor Limited, Kristian Sandengen - Equinor ASA
This session highlights the importance of improving scale treatments, by utilising existing techniques and technologies in an optimal manner to get the best outcome. The session covers both lab and simulation studies. A varied range of techniques are covered including the use of magnets for prevention of scale and the advantages of exploiting synergistic effects from inhibitor blends. A case study is also presented looking at the requirement for an alternative approach for field redevelopment.
