AbstractDuring the '90s, the introduction of battery powered electromechanical intervention tools increased the versatility of slickline service and changed its image from a simple method that performed mechanical workovers to a complex service technology that could provide safe, cost-efficient alternatives for: 1. locating downhole tubular goods/profiles 2. producing quality logs from downhole memory surveys at half the cost of traditional services 3. accurate depth measurement for support of all new completion technologies 4. setting packers without explosives 5. perforating or cutting tubing or casing.Slickline has again expanded its capabilities. In addition to its proven performance for well remediation, maintenance, and pressure control applications, the new enhancements to the self-powered slickline tools can now be used to perform diagnostic and conformance control functions requiring memory production logging.Applications that require electrical initiation or mechanical manipulation at the tool interface can now be performed with slickline and battery power, insulating the tools from the surface equipment. Mechanical signals transmitted through the wire control the tool start and stop functions and provide real time position telemetry. As a result of the advances in service tools, slickline has increased the scope of its services without a compromise to operational safety and job efficiency and offers the most cost efficient services in well workovers.The case histories will describe how the electromechanical intervention tools provide a cost-effective alternative to traditional cased-hole logging systems for many applications as well as many operations that traditionally had to be performed by other service options.

“…The retrieval of depth, line speed, line tension, and time data is readily performed for use with downhole memory production surveys and wire management programs. 4 With accurate depth measurements available on slickline, there is still a question as to position in relationship to collars in the tubing/casing string in the well. A slickline collar locator has been developed to determine in real time, the position of collars downhole, and provide that information to the operator.…”

In the past, slickline service has been considered as an option suited only to routine mechanical well workovers. This is no longer the case. New technology has expanded slickline capabilities to include services for well interventions that have traditionally been reserved for other, more-costly alternatives. This paper will discuss the innovative equipment that has been developed to support this technological expansion, all of which plays an integral part in the expanded slickline concept, specifically:An electronic triggering device that provides a safe, efficient method for firing detonators • A battery-operated, electro-mechanical tool that is capable of setting wellbore devices with slickline and braided line without explosives, • An electronic measurement system that can automatically correct measurement inaccuracies resulting from line stretch and environmental stress factors. • A collar locator that can provide verification of collar locations in a tubing or casing string, • Dataljob loggers or acquisition software systems that can be connected to the electronic measurement system to graphically record dynamic infonnation that occurs during a wireline trip. • A wire line inspection system that can detennine integrity of both new and used mechanical wirelines during and before service. Case histories will be used to provide comparisons of cost, operational efficiency, and enhanced safety features of traditional service options and the new advanced 719 slickline system. Methods for service strategies that support current economic trends and well solutions will also be discussed as well as methods to detennine key needs for appropriate service alternatives.The combined use of these slickline tools provides a stateof-the-art service system that can provide efficient alternatives for the advanced service needs in the oilfield today.

“…One program of the programs from which the system receives data is the Advanced Measurement System. 1 This system was developed to account for the environmental conditions such as elastic stretch, temperature, buoyancy, drag/lift, as well as outof-tolerance measuring wheels that can impact slickline measurement. 2 This measurement system serves as the operator interface and receives depth and wire tension signals from transducers, converting raw sensor data to proper engineering units.…”

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractThe technological enhancements, new tools, versatility, and cost efficiency of slickline services have increased its usage considerably in the last decade. However, an efficient method to capture the integrity of slickline wire prior to its use has not been available until recently. This paper will discuss a new Real-Time Wire-Management System that has been developed to predict the used life of the wire in slickline operations. The system uses a general wire model to detect fatigue failure in the wire. The model results are accumulated for the whole life of each drum of wire, and then, when the use life exceeds predetermined levels, the operator can remove the slickline tool and can make appropriate changes to the wire. A specified amount of line can be cut off to move the bending point to a new location, or the line can be reversed, extending the life of the whole unit by moving the operation to wire that was located previously at the core of the drum. Finally, the system can help the operator determine when a drum of wire should be discarded completely. Field applications have shown that this system can result in enhanced reliability in slickline operations and that cost savings from reductions in catastrophic operational events can be significant.
