Issue: July 1998

Special Focus

Developing smaller offshore fields with FPSOs

Technical advances have made FPSOs viable options for smaller "marginal" fields; a new hybrid riser system extends applications to deeper waters

Field developments/operations highlight new technical advances

Boat-based coiled tubing operations * Third-party mock rig inspections * Terra Nova field, FPSO turret * New chemical for offshore water treating * Petrobrás' Roncador field development * Joint industry FPSO research

Offshore construction program upgrades operating FPSO

Mobil began production through Zafiro Producer in 1996; an extensive vessel modification is now underway with the unit in full operation

Record lateral sidetrack drilled from North Sea platform

How an existing well was sidetracked and kept within a tight sand with state-of-the-art technology to optimize oil recovery using one well

State-of-the-art underwater wet welding

As offshore structure numbers grow, need for underwater repairs increases. Article describes advances in multiple temper bead wet welding
Features

Drilling/ completing with tubing cuts well costs by 30%

How and why Pemex redesigned a Northern area gas well program to drill with 3-1/2-in. tubing, then cement it in as a slimhole production string

Harding field: A North Sea success story

Part 5 – How the team drilled horizontal wells with tight tolerances using high-accuracy surveying, optimal BHA design in 2,000-ft sections

How well control equipment is advancing to meet deepwater needs

Part 2 – Previous focus on riser equipment moves to examination of seafloor components, including wellheads, BOP stacks/ controls and connectors

Inventory correction drives OCTG market

Factors that adversely influence the cyclical tubular market are identified; but the fundamentals, especially gas activity, are seen as positive

Probabilistic OCTG design: Definition, scope, status

Interview with ARCO's Mike Payne answers qustions about how this technique is different, where it can be applied, and how to learn more

Production logging in high-angle wells: Middle East examples

Application/ description of tool designed to overcome typical problems in high-angle wells to get fluid inflow data from all zones

Recommendations could improve the serviceability of drillstring components

Agip's field experience and engineering design work generated proposed new technical specs that can increase shouldered connection life

Select topics and applications of probabilistic OCTG design

Also called "risk-based" design, the technique zeros in on data accuracy, true pipe properties to optimize site-specific tubular designs
