Completing the Well

Milling service designed to reach total depth in extended laterals with one run

With traditional milling services, operators often have to make multiple runs to mill out every plug in an extended lateral. Sometimes, the bottomhole assembly cannot reach the lower sections of the well with enough weight-on-bit to remove the deepest plugs. To help operators reach total depth in a single trip in extended lateral wells, Baker Hughes, a GE company, has launched the coiled-tubing-conveyed Versa Drive extended lateral milling service. In this video from 27 March at the 2018 SPE/ICoTA Coiled Tubing and Well Intervention Conference in the Woodlands, Texas, Erik van Steveninck, Global Product Line Manager, Thru-Tubing Intervention, explains how the Versa Drive is able to reach and remove every plug in a single run. He also discusses a recent field trial in the Permian, during which the service was used to mill out 68 plugs in a single run, without chemicals...

Schlumberger has introduced the Tempo instrumented docking perforating gun system at the SPE/ICoTA Coiled Tubing and Well Intervention Conference and Exhibition. This combination of a plug-in gun design with real-time advanced downhole measurements enables and monitors the well’s dynamic underbalance to create clean perforations that boost reservoir productivity...

Moving from surface readouts to real-time data reduces guesswork to improve intervention efficiencies

The xSight Smart Intervention Service consists of a BHA deployed on drill pipe that is outfitted with sensors measuring torque, WOB, pressure, vibration, toolface orientation and temperature. Data is transmitted wirelessly via mud-pulse telemetry to the surface. The data is fed into a software program for interpretation, then presented as a visualization.

As oilfield sensors and digital technologies grow more sophisticated, the industry is increasingly relying on real-time data to optimize the well intervention process. In today’s intervention operations, downhole data can make the difference between success and failure – and we know that operators can’t afford failures in this low-price environment...

Multistage fracturing sleeve system developed for North American shales deployed in Saudi Arabia to complete record horizontal well

This graph shows the average treating pressure of all the stages in the well.

Multistage completions using sliding sleeves that allow one-stage, multi-clustered implementation with variable or consistent nozzle sizes were introduced for acidizing completions in the North Sea in the late 2000s. As the practice evolved, it became clear that North American shale projects would be more difficult. Although drilling and completion of extended horizontal wells remained more economical than drilling new wells for further access to the pay zone, there were challenges with perforating the extended section. Open-hole completion had been practiced as a solution but was not ideal for use in shale. Injected fluid took the path of least resistance to the formation, rarely covering the entire payzone accurately or efficiently...

SPE/ICoTA conference to showcase technologies, real-world applications for well interventions

spe

Knowledge sharing and innovation are the key benefits of attending this year’s SPE/ICoTA Coiled Tubing and Well Intervention Conference and Exhibition, according to Ian Chapman and Matt Billingham, Chair and Vice-Chair for the upcoming event. The conference takes place 27-28 March in The Woodlands, Texas. Mr Chapman and Mr Billingham agree that, after several difficult years for the industry, the acceptance of interventions as a critical maintenance tool, both from a reservoir management and production enhancement perspective throughout the life of a well, has become critically important...
