RESULTS

The client had previously experienced regular component failures and laborious, time-consuming redress procedures using alternative swivel products, resulting in reduced efficiency and significant project downtime. The run-life of these conventional products were averaging around three deployments before failure, so an alternative was solution was sought for this project.

DTI’s 1-11/16” Swivel was used, replacing the larger 2-1/8” Swivels previously used, and performance was impressive, even when used to deploy large perforating charges.

Two E-Swivels were able to perform 43 and 30 consecutive digital slickline deployments respectively, without redress or failure, compared to the previous average of three runs achieved by conventional swivels. This huge fourteen-fold deployment cycle improvement let to significant operational efficiency gains in the North Sea P&A campaign.

FEATURES AND BENEFITS

The E-Swivel is part of DTI’s wider Electric Line product range, which all benefit from robust design, reliability, long performance life and ease of redress.

The products are designed for heavy-duty continuous use, with state-of-the-art components, including impact resistant bearings and premium rotary seals to withstand high loads and impact shock.

Electrical components are drop-in cartridges which are common across the product range and can be replaced in minutes. They are rated for high current and voltage with enhanced reliability.

These features are ideal to support the use of downhole explosives, which were used in this project, and other challenging field applications.
