Session 1: Cement Job Design Process
Session Chairpersons Anthony Badalamenti, Curistec; Samuel Osisanya, The Petroleum Institute
Speaker(s) Mohamed Oukil Benmesbah, Petroleum Development Oman; Antonio Bottiglieri, Baker Hughes, a GE Company; Alfredo Sanchez, Rubicon Oilfield International

Oil well cementing can have a dramatic impact on a well’s economics and environmental performance. A successful primary cementing job that maintains zonal isolation throughout the life of the well can reduce the well’s construction cost (CAPEX), reduce its production cost (OPEX), and decrease the time required to harvest the reservoir, which translates to higher return on investments (ROI).

However, achieving a successful primary cement job is hard and achieving complete zonal isolation for the life of the well is even harder. This interactive session will focus specifically on the cementing engineering and laboratory processes being used to achieve a successful primary cement job. Topics to discuss will include:

  • Setting cementing objectives and stakeholder engagement
  • Cementing engineering tools including, job placement and mechanical software simulators
  • Advances in cement and spacer design practices
  • Advances in laboratory testing and state of the art laboratory equipment
10:30 - 11:00
11:00 - 12:30
Session 2: Execution
Session Chairpersons Rami Eid, Repsol; Salim Taoutaou, Schlumberger
Speaker(s) Anthony Badalamenti, CURISTEC; Saurabh Kapoor, Schlumberger; Samuel Osisanya, The Petroleum Institute

The cementing delivery process contains four steps, Design, Prepare, Execute, and Evaluate. In the execution phase, all the design and prepare phases should have been performed and closed.

The execution involves pumping the cementing job as designed, pressure, rate, and densities are used to monitor the execution the cement job, they are compared to the designed ones to ascertain that the job went either well or not. Usually the obtained recorded data from the cement acquisition system is analysed using the aid of a cementing hydraulic simulator.

In the recent years, the cementing operations has become a very critical part of the drilling process, being able to predict the results of the cementing job even before the cement sets is decisive to plan the drilling operations ahead. Furthermore, some regulators call for possible barriers verifications early during the well construction phase.

In this session, we will discuss the current cementing job execution practices and look into the future for potential real-time cementing execution and other practices that can improve the cement placement and ascertain the downhole integrity.

12:30 - 13:30
13:30 - 15:00
Session 3: Loss of Circulation–1
Session Chairpersons Yahia Ait Hamlat, OFITE; Alfredo Sanchez; Rubicon Oilfield International
Speaker(s) Pavel Marinescu, MI Swaco; James Barry, Turbo-Chem

Lost circulation or lost returns is a common problem associated with well drilling, cementing, and completion operations. Well fluids can be lost into unconsolidated, highly permeable, vugular, and cavernous formation as well as into naturally or induced fractured zones. Losses severity range from minor seepage to total losses and depending on the severity, losses can be very costly to cure and it can pose serious impact on well economics, safety and integrity. Lost circulation is one of the biggest source of non-productive time.  

Determination of severity and depth of losses can be challenging if it is spread along the open-hole section. There is no clear methodology for determining the severity of the problem and the type of losses and establishing a possible cure for it, that can work in each case. Different operators and service companies adopt different techniques and recommended best practices to combat the problem.

This session of the workshop will shed light on how different operators are dealing with the problem and their rates of success. Special emphasis will be given to case studies from the region as most operators drill across the same formations and face similar challenges. The session will provide an opportunity to exchange views and share the best practices followed. 

15:00 - 15:30
15:30 - 17:00
Session 4: Loss of Circulation–2
Session Chairpersons Bipin Jain, Schlumberger; Abdusalam Schlibak, ADNOC Onshore

Session 5: Unconventional
Session Chairpersons James Gillies, Halliburton; Deryck Williams, Chevron
Speaker(s) Jeremy Downs, Emjel; Animesh Kumar, Halliburton

Unconventional reservoirs are any reservoir that requires special recovery operations outside the conventional operating practices. Unconventional reservoirs include reservoirs such as tight gas sands, gas and oil shales, coal bed methane, heavy oil and tar sands, and gas-hydrate deposits. These reservoirs require assertive recovery solutions such as stimulation treatments or steam injection, innovative solutions that must overcome economic constraints in order to make recovery from these reservoirs monetarily viable.

A successful unconventional cementing solution is one which is designed so that the cement sheath can help serve as a foundation for increasing ultimate recovery by addressing even the most challenging wellbore conditions including corrosive environments, high temperatures as well as large temperature differentials, high pressures and significant pressure differentials. 

This session of the workshop will focus on how different unconventional well cementing challenges are handled and will feature case histories of successful applications of current and novel technologies with special focus on regional applications of technologies and best practices.

10:30 - 11:00
11:00 - 12:30
Session 6: ERD
Session Chairpersons Luis Eduardo Navas Plaza, ADNOC Offshore; Antonio Bottiglieri, Baker Hughes, a GE company
Speaker(s) Andreas Brandl, Baker Hughes, a GE company; Ruben Medina, Halliburton

ERD is proving to be the convenient well construction method for efficient accessibility to hydrocarbon reservoirs around the world and especially with current oil prices.

As we know there are technical, operational and economical cementing challenges that directly impact the life integrity of extended reach wells.

The idea of this session is to openly discuss and share regional and worldwide experiences in order to build a toolbox of practices, improvements and innovations to help cementing and drilling engineers tackle current and next future ERD challenges.

Topics to discuss:

  • Hole geometry and conditioning
  • ECD and loss circulation managements
  • Pipe running and centralisation
  • Spacer and slurry property designs
  • Mud conditioning and removal
  • Cement placement
  • IT Support (Monitoring/data acquisition, and software programmes)
  • Cement bond quality
12:30 - 13:30
13:30 - 15:00
Session 7: Barrier Verification
Session Chairpersons Mohamed Qassem Hussain, ADNOC Onshore; David Stiles, ExxonMobil
Speaker(s) Riefky Abdurrahman, Schlumberger; Francisco Arevalo, Halliburton; James Thomas Ryan, ADNOC

Evaluation and verification of well barrier’s ability to provide pressure isolation is critical to well integrity. The end goal must be assurance that there is effective pressure isolation in the well for all barriers including cement, metal-to-metal-seals, elastomeric seals, swellable elastomers, any other barrier mechanisms. If it is not known what is being evaluated, how it is being diagnosed and what is considered acceptable, then the integrity of the barrier will always be in question.

In this session we will attempt to define the acceptance criteria for a barrier. We will discuss current methods of barrier testing and their effectiveness. Within that framework we will discuss whether more cost effective and reliable verification methods could be developed. Gaps will be identified between the methods currently available and the advancements required to meet the agreed acceptance criteria. 

15:00 - 15:30
15:00 - 16:00
Break-Out Group Discussion
Moderator(s) Shamsa Salim Al Maskary, ADNOC Onshore; Axel-Pierre Bois, CURISTEC

Achieving a successful cementing job requires the engagement and coordination of many discrete/specialised processes, companies, and experts. Effective communications between all parties is key to the safe and efficient design, delivery, and execution of the cementing process.

This thought-provoking session will explore a variety of perspectives and review best practices and methodologies that, when applied, ensure cement-sheath integrity for the life of the well. The workshop participants will be split into small groups. Each group will receive a topic to brainstorm, with the objective to evaluate which solutions are already available, and in which direction the industry should go in order to improve the solution portfolio. Finally, each group will present its conclusion to the audience, with the possibility of additional discussions.    

16:00 - 16:30
