Each well, from a North America land unconventional to a pre-salt deepwater well or a Middle Eastern maximum reservoir contact horizontal, will have different requirements. With different rig sizes, bit sizes, well depths, drilling times, etc. the total...

This paper describes a novel application, where an ultra-compact coiled tubing unit (UCCTU) was designed and built for shallow geothermal well drilling and reservoir/aquifer...

...-gas demand of the country. As part of this strategy, operators have opted for different strategies to target the untapped gas reservoirs. One such application has been the use of coiled tubing (CT) for underbalanced drilling (UBD) in sour wells. The UBD technology has enabled the development...

... Abstract This paper describes a recent Directional Coiled Tubing Drilling (DCTD) job that was completed for an independent operator in the Appalachian Basin. The objective was to access target zones identified adjacent to a recently drilled, vertical well using a lateral sidetrack. The target...

... Abstract In November 2016 the Deep Exploration Technologies Cooperative Research Centre (DET CRC) launched the RoXplorer ® , a coiled tubing (CT) drilling rig for greenfields mineral exploration, delivering a platform for low-cost, rapid, safe and environmentally-friendly drilling. The launch...

... Coiled tubing technology is utilized in the oil and gas industry in various applications for several decades. Coiled tubing was initially started in the mid-1960 to perform intervention work such as clean outs or scale removal within existing wells. It was followed by very simple drilling...

... of Statoil drilling and well operations in Norway. This paper will: Discuss the introduction and uptake of tractor related services within the historical context of Statoil operations in Norway. Provide context in terms of the reservoir, well and operational environments encountered on Statoil...

... Abstract Coiled tubing drilling (CTD) technology has been widely adopted as a cost-effective re-entry strategy to sidetrack from the existing wellbores, and drill high angle/horizontal wells to maximize recovery from remaining oil columns in the Alaska Prudhoe Bay field. The oil rim...

... declined over time, making new opportunities for matching technology to economies of scale for such marginal projects. This paper outlines the recompletion of an old field using radial jet drilling, RJD. The reservoir in K-block, Tarim oilfield of China is a siltstone formation with low permeability...

...Introduction—Fixed Platform This intervention operation was completed on a fixed platform with drilling, production, and workover capability. On a fixed platform, the number of possible wells is limited by the number of slots. Access to multiple pay zones is provided by multiple sidetrack...

... Abstract Once the decision is made to complete a well in order to begin producing, the operator wants to complete the task as soon as possible. One completion task is to drill through multiple completion plugs so the pay zones can begin producing. In the past, drilling these plugs has gone...

The mud properties were controlled within the specification to maintain sufficient carrying capacity to carry out the cuttings. The actual hole cleaning performance was assessed by comparing the theoretical volume of rock...

... Abstract One main challenge facing the Shell Pinedale Anticline completions is effectively drilling 21 plugs per well throughout a 6500′ hydraulically fractured completion interval (7,500′ – 14,000′ TMD) in a safe, timely, and cost effective manner. Ths process of drilling plugs has improved...

This can be done without tripping out of the hole or stopping drilling operations to rig up and run a traditional wireline gyro. To fully...

... Well MD-330 is just one of the successful Coiled tubing – Underbalanced drilling re-entry wells drilled in Hassi Messaoud field during year 2006. The formation pressure was sufficiently high (5600 psi) to induce underbalanced conditions with native crude (45°API, 0.80 S.G.) without the necessary...
