Digital-Slickline Capability on Plug-and-Abandonment Conveyance Phases

Slicklines often play a vital role in offshore plug-and-abandonment (P&A) operations, either in those phases of the operation that require slickline conveyance or because logistical, footprint, operational, economical, environmental, or regulatory parameters of a P&A necessitate full reliance on this small, light, cost-effective conveyance offering. P&A activities using digital slickline increase equipment, logistic, and marine-support efficiency.

Introduction

Slickline-conveyance services have long been used in the exploration and production industry, with much of the slickline equipment, processes, and capabilities remaining relatively unchanged. Mechanical services have remained slickline’s mainstay. Evolutionary enhancements resulting from developments in metallurgical engineering are applied to the line itself and the mechanical tools deployed, along with improvements in pressure-control and winch technology used to deploy the tools and services safely in live wells. Oilfield application of battery-powered electronics in downhole tools began in the late 1970s, eventually including electronics-based devices such as gauges, firing heads, bottomhole-fluid samplers, and production-logging and caliper tools, as well as hydraulic tools. Slickline services were soon offered to both remedial services (pipe cutting, tubing punching, and perforating) and measurement services (production, pipe, and cement-bond-integrity logging). The demand for slickline services has remained steady over the years because of its many inherent advantages: minimal footprint; ease of logistics to, from, and on the wellsite; operational simplicity; and overall cost-effectiveness.
