Implementation of State of the Art Coiled Tubing Technologies in Challenging Completions

Click here for a sneak peek of the webinar.

Two industry experts will provide insights on new coiled tubing technology applications focused on driving innovation and incremental well performance. This will be a combined webinar presentation that will focus on cost effective abrasive jetting technologies and real time assessment of stimulation fluid diversion by employing coiled tubing fiber optics.

“Abrasive Jetting Applications throughout the Life of a Well-From Drilling to Plug and Abandonment”

The use of abrasives mixed in a fluid under pressure has been used in the oilfield for over 50 years. Abrasive jetting was rediscovered as a perforating method on coiled tubing in the late 1990’s and has demonstrated distinct advantages over traditional explosive perforating. Today’s abrasive jetting technologies seek to find ways to combine the superior performance and safety into increasingly cost efficient methods to save operators time and money. Applications for abrasive jetting can be found from drilling to production to plug and abandonment, making it extremely versatile.

This presentation educates the participant about new applications for abrasive jetting technology throughout the life cycle of the well. Abrasive jetting is no longer just a means for perforating casing – it can be used to help free stuck pipe in drilling; reduce coiled tubing runs for completing new wells; recomplete and stimulate producing wells; evaluate cement bond during plug and abandonment activities; and more. Technical improvements are also discussed that improve effectiveness of the technology and are demonstrated in case histories. We will also look at what the future holds for this technology and where the next benefits can be found.

“Overcoming Challenges of Stimulating a Deepwater, Frac Pack Completed Well in the Gulf of Mexico Using Coiled Tubing with Real-Time Downhole Measurements”

Achieving effective fluid coverage of stimulation operations in deep water frac-pack completions is often challenging due to a variety of factors, including but not limited to the length of screened intervals, the uncertainty of damage mechanisms, and the ability of diversion materials/fluids to divert beyond the screens and into the formation. This case study demonstrates a successful technique used in conditions not previously attempted.

This particular well had two deep high pressure commingled zones. Previous operations had indicated the presence of a fish or obstruction near the lower portion of the bottom zone. Several previous attempts to stimulate the well had failed. This was one of the deepest uses of fiber optic cable ever attempted, and the tools used needed to be tested and rated for operations outside their rated operating envelope.

This treatment with fiber optic equipped CT and a rotating, hydraulic high-pressure jetting tool was able to achieve a successful stimulation of a 500 ft long frac packed zone after several previous failures using different techniques. A 75% increase in production was achieved by using a CT equipped with fiber optics and downhole measurement tools. Engineers were able to perform a data-driven operation based on real-time bottomhole measurements and distributed temperature surveys.
