cementing

This paper investigates the effect of calcium oxide as an expansive agent on the performance of geopolymer-based sealing materials, with successful application in oil and gas wells at shallow depths.

Given the diversity of coiled tubing well-intervention data, many acquisition labels are often missing or inaccurate. The authors of this paper present a multimodal framework that automatically identifies job type and technologies used during an acquisition.

his paper presents research and application of a sustainable, low-density geopolymer alternative to Portland cement for cementing applications in low-temperature wells.

This paper presents laboratory testing and application of a resin-cement system designed to be placed as a tail slurry to provide enhanced mechanical properties compared with a conventional slurry.

This paper describes a foamed cement solution designed and implemented to cement shallow intermediate casing strings in a heavy oil play in Northeast Alberta.

This paper presents an evaluation of geopolymer cementing for use in oil and gas wells, specifically in the primary cementing of liner strings in the Permian Basin.

This paper presents a laboratory-based study that compares the three methods to measure static gel-strength development that are widely accepted in the industry.

The authors discuss a modified ultrasonic-cement-analyzer (UCA) vessel that allows assessment of slurry sealing performance under representative downhole conditions while running otherwise standard UCA equipment.
