HPHT

Reviewed by BP, STATOIL and most major service companies.

During the last two years this manual has served the completions engineer with a comprehensive account of HPHT operations. The manual covers a range of topics that include the HPHT completion work process proceeded by general information and definitions. There are over 15 specialist chapters including detailed information on Completion fluids, Production chemistry and Elastomer selection.

It thoroughly investigaes the nature of metallurgy and corrosion under HPHT well conditions - in addition, the reader will study details on well testing eluding to, for example, H2S and Hydrate problems. Both surface and down hole are considered. Within the manual, the author looks at Coiled tubing and Wireline interventions illustrating all sections with a final chapter that contains examples of past HPHT completions.

There is a comprehensive chapter on HPHT perforating which undertakes to instruct the reader in the choice of explosives, shot densities, phasing, overbalance versus underbalance arguments, etc. These lead onto reference areas where HS&E considerations are studied.

Another chapter examines sand control methods, practices and constraints in the extreme well environment directing the reader to alternative methods of completion. Allied to this, there is a critical look at Frac-Pack, Gravel Pack and expandable sand screen solutions.

In all there are nineteen chapters. To aid the reader in assessing a strategy for HPHT completions and operations, there are checklists and summaries at the beginning of each chapter and for those who need to research their subject further, each has its own bibliography/suggested further reading.

This manual is a first stop 'production' tool for all those engaged in HPHT well testing, intervention and completions. It will also be of interest as a general reference guide for project managers who are tasked with planning and designing future well appraisal and testing programmes.
