Technical Agenda

Monday, 10 June, 0830-0930

Session 1: Introduction/Opening/Keynote Address

1000-1200

Session 2: Pore Pressure and Fracture Gradient Prediction

While traditional pore pressure prediction methods such as basin modelling, 3D seismic velocity evaluation, and predictions based on offset wells are accepted methods for HPHT well planning and design, their accuracy is not sufficient to allow wells to reach target depth safely and efficiently. Recent technologies such as managed pressure drilling, real time pore pressure measurement while drilling, look-ahead seismic while drilling and real time 3D modelling while drilling greatly enhance the success in drilling HPHT wells.

This session will focus on how these recent technologies, from prediction to measurement, will aid in successfully drilling and producing HPHT wells.

1300-1500

Session 3: Well Design and Life Cycle Integrity and Field Development Planning

Well design is a key element that needs to be addressed when planning HPHT field development or drilling an HPHT exploratory well. A robust well design has well and life cycle integrity at its very core. Factors such  as  absolute  pressure,  absolute  temperature,  differential  pressures,  differential temperatures, presence of H2S and CO2, geological challenges, and rock mechanics challenges will influence a well’s life cycle integrity. A systems approach to HPHT well design is required, calling for meticulous attention to detail and emphasis on the understanding of inter-related components.

This session will host discussions on:

  • Current temperature and pressure limits for HPHT well design.
  • Capability of current technologies to ensure a robust well design.
  • Main considerations when planning to develop an HPHT field.
  • Factors affecting well integrity in the short and long term.
  • Consequences of getting it wrong during the design phase.

1515-1715

Session 4: Lower Sandface Completion Design and Life Cycle Integrity

Managing the various challenges when drilling an HPHT well requires new operational procedures, careful equipment selection, rigorous equipment qualification, and the use of unconventional materials and fluids.

This session will host discussions on:

  • Material selection to withstand the high stress environment.
  • High operating temperatures.
  • Chemical reactivity of well fluid components enhanced by the elevated temperatures.
  • Narrow margin between the boundaries of load uncertainties and equipment material rating.
  • Fit-for-Purpose completion design to provide maximum productivity and maintain well integrity.
  • Detailed and prolonged completion planning process.

1715-1815

Session 5: Poster Session


Tuesday, 11 June, 0830-1030

Session 6: Tubing Accessories and Upper Completion

As the industry continues to turn its attention to HPHT development, complex hurdles in completions need to be overcome. This includes availability of:

  • Robust stress and loading analysis.
  • Suitable elastomers and tubing/completion jewelry metallurgy.
  • Fast, accurate, and reliable setting of plugs and packers.
  • Flow control and smart well technologies.

This session will address the technology available today and the need for more innovative HPH technologies to help operators increase completion efficiency, integrity, and reliability.

1045-1245

Session 7: Material Selection and QAQC

One of the main technical challenges recognised by the industry whilst tackling HPHT projects lies in material qualification and selection for different downhole equipment such as the Oil Country Tubular Goods (OCTG), wellheads, christmas trees, and even the electronics in the measurement tools.

This session demonstrates the importance of QAQC and provides a platform for both operators and material suppliers to illustrate what the industry has in the works as well as the requirements to enable these HPHT development projects to be realised while maintaining long term well integrity. It will include discussions on:

  • OCTG materials and connection limitation.
  • New downhole materials being developed to address the need of HPHT/Ultra HPHT projects.
  • Lessons learned from HPHT project field failures.
  • The criticality of QAQC, ensuring quality materials are selected and fabricated.
  • Applicable QAQC processes for HPHT development.

Session 8: Well Construction, Well Control, and Cementing

Constructing a well under HPHT conditions can prove to be difficult. This session will discuss methods for drilling efficient HPHT wells using the latest risk-averse techniques and well control policies, efficient well construction techniques, and advances in cementing technology to ensure long term zonal isolation.

This session will host discussions on:

  • Well construction techniques to minimise drilling days on exploration HPHT wells.
  • Well control techniques/equipment for HPHT environment.
  • Using elastic cements to ensure long term zonal isolation in HPHT environments.
  • Design techniques for long term integrity in HPHT wells.

1045-1245

Session 9: Data Acquisition and Well Testing

Be it exploration, development, or production, well testing, and in-well measurements are certainly the key to reservoir characterisation and performance management. With the advent of new technologies, from HT cables to HP gauges, nanosensors to conventional measurement devices, the choices available to meet well testing needs and in-well data measurement are becoming more common. But how reliable and useful are these solutions? Can effective workflow automation and data management help us make wise decisions to meet production targets?

This session intends to address available technologies for well testing in HPHT environments and data acquisition techniques used to plan and optimise reservoir performance.

1345-1545

Session 10: Production and Flow Assurance

With an increasing number of challenging wells becoming commonplace, more advanced flow assurance simulation is required to plan and operate these wells with an acceptable risk. Equally crucial are HPHT well completion designs that will accommodate all flow assurance issues encountered. Dynamic modelling, coupled with proper cost and risk considerations are important to ensure safe, sustainable production can be contained within operating expenditures.

This session discusses a range of issues that can only be overcome through careful calibration during production operations.

1600-1800

Session 11: Stimulation and Well Intervention

At some point in a well’s life, its production may drop off to levels where it is not economically viable to continue operating the well. In order to continue operations, it may be necessary to use well stimulation to boost production back up within range. However, HPHT wells pose significant challenges to conventional well stimulation methods. How does one access existing HPHT wells after completion when stimulations and interventions services are deemed necessary? Normal tool specifications may be insufficient to cope with the conditions around elevated temperature and intervention tools could face a pressure collapse.

This session will host discussions on:

  • How far can we go in HPHT wells with conventional stimulation and intervention today?
  • What are the main technical challenges for stimulation and interventions and how/when will they be overcome?
  • What will be needed ahead and what type of solutions can we expect to achieve?
  • Operational examples of HPHT interventions and stimulation.

1800-1830
