T. Cox
Review of mud systems used over 40 years relative to downhole corrosion protection. Important tips on system chemistry and tubular handling
How to optimize production from plunger lift systems

D. Phillips and S. Listiak
Part 2 - Guidelines for maintaining primary plunger lift components, plus a troubleshooting chart to aid in keeping the system efficient
Hydrogen peroxide: A new thermal stimulation technique

J. H. Bayless
Possibilities for practical use of the chemical to generate heat around the wellbore to lower oil viscosity or remove formation damage
Reduced-clearance casing programs offer numerous advantages

J. W. Barker
Methods for determining acceptable clearance between casing strings to optimize casing sizes for today's more challenging completions
Scale removal process facilitates successful well workover

S. Cooke, L. Skinner and N. Adams
How Phillips used coiled tubing to remove scale, fish a safety valve and kill the well when problems stalled a conventional workover

Features

Challenges of ultra-deepwater pipeline construction

L. Gifford and J. Mair
Large diameter pipelines in very-deep water require special techniques such as free-flooding and use of mechanical vs. welded connections
