This paper presents a study that confirms glass-reinforced-epoxy-lined tubing as a reliable, cost-effective solution for long-term water-injection service in moderate-salinity offshore environments.
A circular economy emphasizes reducing, reusing, recycling, and removing parts of existing systems to optimize them with respect to resource utilization. The following papers demonstrate how these pillars of a circular economy are enabling operators all over the world.
This paper introduces in-pipe inspection technologies enabling high-resolution digital measurements of tubular internal diameter and wall thickness for critical downhole applications.

Riser margins were abandoned when fluid columns in risers became too long with increasing water depth accessed when floating drilling units with subsea blowout preventers (BOPs) moved to deep water. -
A methodology is proposed for design of subsea flowlines and risers coupled with a subsea high-integrity pressure protection system (HIPPS) for fields with high shut-in tubing pressure (SITP).
-
This paper discusses the available methodologies for remediation of a pipeline affected by sand and presents examples where the discussed methodologies have been applied.
-
This paper presents a methodology to estimate the probability of failure of every individual corrosion defect and the residual likelihood of failure of an overall corroded pipeline segment after selected repairs, using structural probabilistic analysis.
-
This paper presents the results of tests conducted to design a fast-breaking gelled fluid for a debris-removal operation in a long, large-diameter subsea pipeline in the Asia Pacific region. where traditional pigging was not an option.
-
This paper highlights the issues and challenges surrounding pipeline trenching and burial in ice-gouge environments. The current state of practice is discussed along with the technology gaps that need to be addressed.
-
The present work describes the development of a 1D steady-state isothermal reservoir/surface gas-pipeline-network model. The developed model is an extension of the general pipeline-network model in which the deliverability from the wells is calculated.
-
Systematic experimental and modeling approaches to designing a safe operating strategy for a 5-km deepwater-subsea-flowline case study are presented to address unplanned shutdown and restart events for waxy-crude production.
-
Operators are increasingly recognizing the need for a systematic assessment and management of flexible pipe integrity, but the identification of critical criteria and the means to best achieve valid and efficient inspection and monitoring (I&M) continues to evolve.
