Paper presented at the SPE/ICoTA Well Intervention Conference and Exhibition, March 26–27, 2019
Paper Number: SPE-194235-MS
.... In other instances, water is lost to the formation and new freshwater is constantly being added, minimizing the effects of water re-use. The guar or xanthan gels used, which are biopolymers, act as a food-source for bacteria and create an environment in which bacteria can flourish. Those favorable...

Paper presented at the SPE/ICoTA Well Intervention Conference and Exhibition, March 26–27, 2019
Paper Number: SPE-194236-MS
... Only brine, not produced hydrocarbon, was used in Phase 3, as the extracted core was already water-wet and the test intended to prevent any potential relative permeability effects in the data. Each core was then "damaged" using the synthetic oil-based mud by circulating the mud across the face...

Paper presented at the SPE/ICoTA Coiled Tubing & Well Intervention Conference & Exhibition, March 24–25, 2015
Paper Number: SPE-173686-MS
... in the Bellota-Jujo field when multiple intervals are open. However, the effectiveness of the diversion had not been evaluated in real-time. A distributed temperature sensing (DTS) option was deployed to measure temperature profiles along coiled tubing (CT) equipped with an internal fiber-optic cable...

Paper Number: SPE-173640-MS
... effectiveness for each zone treated, but uncertainty of the friction pressure in the pipe while pumping can result in an incorrect interpretation of fluid entry. These mechanical isolation techniques are typically more costly and time consuming than bullhead jobs. Diversion techniques for bullhead stimulation...

Paper Number: SPE-163909-MS
... time creating a survey that identifies, qualitatively, the admittance of the treated pay zones based on the formation’s cold-down/heat-up effects. Unfortunately, this technique had some limitations as the data recorded needed to be converted, interpreted, and then translated into common oilfield...

... reduction tools to optimize and extend the range of coil tubing. Using case history from Shell Canada’s Groundbirch shale gas development, this paper will compare and analyse the effectiveness of three different downhole friction reduction tools currently available to industry. While this paper...

... into the annulus on various wells. Using the data available from the logs and surface casing failures, the effectiveness of the corrosion mitigation program was evaluated. The main focus of this paper will be the methodology and conclusions obtained from the evaluation. This paper will: Review the cause...

Paper presented at the SPE/ICoTA Coiled Tubing Roundtable, April 5–6, 2000
Paper Number: SPE-60721-MS
.... A laboratory and field testing programme has been completed and data is included. By detailed design of the internal fluid path, orifice geometry, jet stand off and pump rates, tool effectiveness has now been improved to a level several times more efficient than previously available for the same feed...

... for underbalanced drilling fluids. Liquid nitrogen does an excellent job of inserting the drill fluid and reducing corrosion potential. Membrane gas, which is generated using membrane fiber technology and air compression/boosting equipment, is an effective means to reducing hydrostatics. This paper will discuss...
