2019 Meeting Programme

14-15 March Well integrity and well control, enhancing competence in the drilling industry
Meeting Introduction

Well integrity and well control, enhancing competence in the drilling industry
While well cost pressures have intensified in recent times, the requirement for well integrity has remained absolute. As we have evolved the production cycle well integrity must now stretch to the abandonment phase to ensure the safe deconstruction of the well. The Meeting will focus on methods to ensure integrity while the well is under construction through drilling and casing practices, wellbore fluid management, cement management and others, looking at current best practices as well as developments to increase the real time management of the well.Hand in hand with well integrity comes well control; this is the most important factor in day to day operations that, when it goes wrong, can have catastrophic consequences.Finally to manage all of the above, there is a requirement for competent wellsite and remote monitoring of all the data streams produced – and how has the industry worked to ensure as we go through the downturn driven “crew change “that we are not in a position of having to re-learn hard won lessons.The following topics are areas of interest however other relevant suggestions are welcome:

  • Early kick detection and other real time well monitoring
  • Advances in well bore fluids to enhance well integrity / control
  • The role of mentoring in the development of offshore competencies
  • Casing integrity, in running and well life
  • Wellhead design testing and delivery – the case for a 30K wellhead
  • Well control in “runaway” situations (capping stacks / relief wells)
  • Enhanced / learning use of simulations to learn lessons “offline”
  • Cement development, flexible cements for the future
  • Advances in rig design / safety to ensure well control
  • The roles of different barrier types
  • Non-cement, cements, i.e. alternatives
  • Drilling practices, evolution and the use of “big data” to manage small events

13-14 June Techniques and technologies to sustainably reduce non productive time
Meeting Introduction

Techniques and technologies to sustainably reduce non productive time
20% has been a commonly quoted average figure for non-productive time on drilling and completion operations for many years. That is one fifth of the time spent on an operation not making tangible progress towards the objective.
During the planning phase of an operation an engineer decides how much NPT is expected occur and how to incorporate this into the planned cost. In effect this can mean the acceptance that a significant proportion of the operation cost is potentially avoidable.
Reducing industry NPT is therefore a key lever in lowering unit development cost and consequently maximising economic field recovery. The effort to reduce NPT can be focused on a number of areas such as quality management, equipment specification, operational planning and training.The following topics are areas of interest but other relevant suggestions are welcomed:

  • Case studies in achieving significant NPT reductions
  • Novel and efficient processes for tackling NPT
  • Uses of new technology in traditional NPT prone operations
  • Minimising the impact of severe met ocean conditions
  • One off large NPT events vs small repeated events
  • Coping efficiently with unexpected operational trouble
  • Drawing from other industries NPT experiences
  • Accurately forecasting NPT for operations

12-13 September Enhancing drilling efficiency, vibration mitigation and hard rock drilling technology
Meeting Introduction

Enhancing drilling efficiency, vibration mitigation and hard rock drilling technology
Drilling efficiently and improving drilling times is high on the wish-list of any drilling team. From the start of the downturn targets for efficiency gains in the order of 30% were spread widely. Can we conclude today: “Mission Accomplished”?
Taking one step back, we know that reducing drilling time is often not as simple as pushing harder. In hard rock drilling applications for example we often realize that higher energy input can lead to destructive loads on the equipment. The actual dynamic loads downhole (due to vibration and shocks) can be much greater than those inferred from surface. This means a deeper understanding of the systems’ interactions is required, as the exact characterization and solutions for such problems are complex. This applies to any drilling system pushed to its limits.
Needless to say that even expected Rates of Penetration in low single digits urges engineers to enumerate potential solutions or even simply act without a strategy.
Which innovations and improvements to the drilling process have been made to enhance drilling progress rate?
Technical presentations and case studies related to the following topics are of interest but other relevant suggestions are welcomed:

  • Surface techniques, control and technology to mitigate downhole vibration
  • Downhole measurements and actuators to reduce downhole vibration and enhance progress rate
  • Hard Rock drilling techniques and technology
  • Bit-Rock Interaction, Bit Innovations, Bit wear prediction
  • Drilling Dynamics Characterization and Modeling
  • Offset analysis/ Benchmarking Performance
  • Efficiency improvements through Performance Coaching and Performance Contracts
  • Efficient Strategies: single run versus dedicated bit-trips, Wait & See, Trial & Error, All-In

12-13 December Advancement in plugging and abandonment technology
Meeting Introduction

Advancement in plugging and abandonment technology

The industry is currently facing challenges with high costs in plugging and abandonment operations. New, effective solutions are required to address this.

The slot recovery operations that are needed to drill new sidetrack wells from brown fields, are a major part of the total new well cost today. New wells are important to keep production high and efficient slot recovery is directly linked to extending the life time of the producing field. The plugging operations need to be carried out safely and efficiently, without unacceptable risks to people, environment and facility. Safety is important in the temporary plugging phase and in the final abandonment of the field.

The initiative, study and implementation of new effective P/A solutions requires to be accelerated, both with regards of technical solutions and modelling of acceptable barrier solutions. The qualification of formations as a barriers or as a storage capacity for capturing minor amounts of gas could play a major role in this aspect and overburden management is an important part of this solution. The industry needs to follow and support development of regulatory requirements. Sharing experiences and lessons learnt in the advancement of plugging and abandonment is important for the industry to extend the lifetime of drilling and well operations in the world.
