HIGH PRESSURE HIGH TEMPERATURE COMPLETIONS

About this Course The completion of high-pressure/high-temperature (HPHT) wells involves high-risk and high-cost operations with exposure levels among the highest in the completion sector. The risks and demanding performance requirements for HPHT completions dictate special engineering considerations and investments. To ensure that completion equipment will perform safely and productively in specific HPHT environments, it is important to accurately define a set of operational parameters and performance rating requirements for any new equipment, set approved design specifications “in stone” as soon as possible and ensure that engineering feasibility work is accurate so equipment can be delivered as designed.

Who should attend this course? This course is aimed primarily at completions and drilling engineers. It is also aimed at those that are influenced by HPHT issues (e.g. reservoir engineers, project managers, subsea and facility engineers). The course will benefit vendors, service companies and other specialists. The course assumes basic knowledge of completions.

This course covers the current challenges and solutions with HPHT Completions: Definition of HPHT and where the HPHT developments are occurring.

The reservoir completion challenges – HPHT sand control, perforating and stimulation.

Fluid behaviour and well performance – why HPHT reservoirs are often condensates and the issues inherent with modelling the well performance of these fluids.

Do we need artificial lift on HPHT wells? Surprisingly often but difficult to design.

Production chemistry challenges exacerbated by high pressures and temperatures – specifically hydrates and salt deposition.

Metallurgy solutions for HPHT reservoirs – are HPHT conditions always more severe – how can we design cost-effective tubing and casing. The specific concerns with stress corrosion cracking.

Tubing and casing stress analysis for HPHT reservoir – specific issues and solutions – temperature dependent yield, thermal expansion, annulus pressure build up (and contraction) and wellhead growth.

Equipment for HPHT completions.

HPHT installation issues and completion fluids – the challenges with kill-weight brines.

Attendees will receive bound printed copies of overheads and a copy of “Well Completion Design” book signed by the author.

Key Objectives of Attending:

Be able to define the

specific completion issues that every HPHT development will need to account for during the design phase.

Can select an appropriate perforating, stimulation or sand control strategy within the limitations of well interventions under pressure.

Be able to model the flow performance of HPHT completions.

Ba able to select the appropriate materials and metallurgy for HPHT conditions.

Be able to include HPHT specifics (such as anisotropy) in the tubing and casing stress analysis.

Be able to produce a well design and associated outline procedure that is safe to install and operate – adequate barriers, addresses flow assurance issues etc.

Can define an appropriate completion fluid and address the difficulties with operating with kill weight brines.
