This seminar will teach participants how to identify, evaluate, and quantify risk and uncertainty in everyday oil and gas economic situations. It reviews the development of pragmatic tools, methods, and understandings for professionals that are applicable to companies of all sizes. The seminar also briefly reviews statistics, the relationship between risk and return, and hedging and future markets. Strategic thinking and planning are key elements in an organisation’s journey to maximise value to shareholders, customers, and employees. Through this workshop, attendees will go through the different processes involved in strategic planning including the elements of organisational SWOT, business scenario and options development, elaboration of strategic options and communication to stakeholders. Examples are provided including corporate, business unit and department case studies. Safety leadership focuses on the Human Factors (HF) which complement technical training to optimise reliability, safety, compliance, efficiency, and risks within a team-based environment. The IOGP laid down the HF skills and competencies required, and they form the basis for specialised O&G HF training's delivered by Mission Performance. This 1-day course reviews the key human factors but then also reviews what can be done to accelerate and scale operational roll-out for optimum and sustained impact, including integration with existing safety processes and (reporting) systems, refreshers, assessments, measurements, as well as the role of leadership and culture. Decisions in E&P ventures are affected by Bias, Blindness, and Illusions (BBI) which permeate our analyses, interpretations and decisions. This one-day course examines the influence of these cognitive pitfalls and presents techniques that can be used to mitigate their impact. Bias refers to errors in thinking whereby interpretations and judgments are drawn in an illogical fashion.

The main focus of this work is benchmarking of calcium carbonate (CaCO3) scale risk and its use in field development and operation phases. In general, defining a scale management strategy and design of new wells during field development are based on thermodynamic calculations, kinetic considerations and field observations. Experience has shown that wells with high temperature and high-pressure drops are prone to downhole calcium carbonate scaling, however there was a need to be more predictive concerning absolute values of temperature and pressure drops. The result from the work was a plot which has proved to be a powerful tool in planning of new wells, e.g. in the North Sea Oseberg field.

For the last 30 years, wells in the field have been suffering from medium to high corrosion rates in both near surface and downhole components. Remedial measures had been implemented in order to restore Well Integrity with different techniques. Corrective actions aside, a strong preventive approach is needed to better understand the root causes of such corrosion rates and scenarios where the integrity of specific wells has been seriously compromised due to corrosion problems. Taking a step further and considering the big implications of new projects such as Artificial Islands project, where the company will be drilling & completing over 300 Extended Reach Drilling (ERD) wells, Well Integrity input as a discipline becomes critical in order to ensure previous problems will not be repeated and all lessons learned throughout the years will be wisely taken into consideration when designing a new well to remain integral during its whole expected life. Understanding of the current corrosion mechanisms in the field was the key to find not only solutions, but also, to create an approach aimed to improve the future completion for Island wells in terms of design, materials and many other factors. An extensive multidisciplinary approach was carried out in order to successfully complete a full study in one of the pilot wells completed with Inflow Control Devices (ICDs), which will be analyzed in detail in this paper, covering the following areas: i. Well design and configuration ii.
The first presentation will demonstrate how an integrated and systematic approach to predicting scaling potential was used to appropriately monitor and manage scale during unconventional production. The next case study will show how computational fluid dynamics modelling helped on the Nova Field to significantly improve scale inhibitor squeeze placement in an open hole horizontal with large reservoir pressure differences along the well, through the application of non-Newtonian fluids and inflow control devices. Finally, a study involving the comparison of carbonate scaling tendency and scavenging ability of six different H2S scavengers will show that chemistries are available that scavenge efficiently and do not increase carbonate scaling tendency.
