A Novel Method For Coiled Tubing Installation

Offshore Technology Conference, 2008
Abstract Installation of flexible pipe for offshore developments is costly due to both the physical cost of the flexible pipe, and the expensive day rates and availability of suitable installation vessels. Considering the scarcity of flexible pipe in today's increasingly demanding and busy market, operators are ...

Effects of Buckled Tubing on Coiled Tubing Passibility

SPE/ICoTA Coiled Tubing and Well Intervention Conference and Exhibition, 2017
Abstract Many coiled tubing(CT) operations involve passage through the production tubing. However, due to the adverse wellbore trajectory or tubing geometries, especially in helically buckled tubing, the CT operations are still encountering various bottlenecks when it is pulled or lowered through the tubing. In this paper, a new concept "

Using a Wireless Coiled-Tubing Collar Locator Tool on Coiled-Tubing Fracturing Operations

Canadian International Petroleum Conference, 2002
Abstract Fracturing operations through coiled tubing represent one of the newest and best uses of coiled tubing. Large-diameter coiled tubing is used to convey straddle packers that are used to isolate particular zones to be fractured.

Laying Sand Plugs With Coiled Tubing

Proceedings of SPE Production Operations Symposium, 1993
ABSTRACT A successful technique for placing accurate amounts of sand inside casing was developed for the Western Operating Area (WOA) of the Prudhoe Bay Unit (PBU) on the North Slope of Alaska. Using coiled tubing and a multistage pumping schedule, a sand plug can be laid in one, time-saving operation.

New Higher-Strength Coiled Tubing Developed to Extend Coiled Tubing Operating Envelopes

SPE/ICoTA Coiled Tubing & Well Intervention Conference and Exhibition, 2011
Abstract A new high strength coiled tubing grade has been developed to address the demands for improved axial strength, better fatigue performance and the ability to function at higher operating pressures. Coiled tubing service companies and operators defined several areas where existing coiled tubing grades are not considered capable of

An Analysis of Coiled Tubing Performance

SPE/ICoTA Well Intervention Conference and Exhibition, 2019
Abstract The performance of coiled tubing pipe in real-world conditions is a topic of interest and frequent discussion within the industry. With pipe cost routinely exceeding $250,000 per string, service companies want to know if they are achieving the maximum return on their investment, and how their utilization compares with their ...

Coiled Tubing Conveyed Perforating

Proceedings of SPE Latin America/Caribbean Petroleum Engineering Conference, 1996
Abstract Perforating and pipe recovery operations performed with coiled tubing provide logistical and technical advantages in certain situations. Conventional tubing conveyed firing head adapters have been redesigned to be conveyed by this method which is activated by coiled tubing pressure.

Effects of Coiled Tubing Injector Head Abrupt Stop on the Coiled Tubing Strings

SPE/ICoTA Well Intervention Conference and Exhibition
Abstract This paper investigates the mechanical consequences of abrupt stops of coiled-tubing (CT) injector-head movement during heavy-pipe running-in-hole (RIH) operations. The objective is to quantify the transient dynamic loads produced during abrupt deceleration events, correlate those events with field-observed longitudinal plow ...
