This paper describes the use of coiled tubing in a pilot project for carbon dioxide injection, enabling evaluation of the conversion of an existing oil field for CCS purposes and derisking storage-development uncertainties before having to cease hydrocarbon production.
This paper describes the first riserless coiled tubing services operation performed in a live subsea well and the associated improvements in efficiency, cost savings, and safety.
This paper describes a case history in the UAE in which the cleanout of scale contaminated with naturally occurring radioactive material was conducted successfully.
-
Regulators told some injection well operators close to the epicenter of a magnitude 4.0 earthquake that they will have to shut down their operations indefinitely. -
This paper presents design considerations and field-trial applications for determining practical dimensions and limits for interdependencies associated with stage length, perforation clusters, and limited-entry pressures.
-
Two US test sites have fractured hot, dry rock with plans to create a network of fractures for water heating. They will soon find out if the fractures worked as expected.
-
A high-resolution acoustic downhole evaluation system nabs top award for 2023.
-
This article presents a new data-driven analysis to locate low-frequency seismic sources, referred to as near-infrasound or infrasound sources. Combining these infrasound signals with microseismicity signals allows for better characterization and monitoring of the stimulated reservoir volume.
-
Fracturing hot rock to create a geological water-heating system is like fracturing an oil well, but for a different purpose, so is proppant really necessary?
-
When confronted by extremely hot wells drilled into hard rock, engineers start looking for new tools and then ask, is there a cheaper option?
-
EcoShield also reduces carbon footprint of well construction over traditional cement systems.
-
From refracturing old wells to ones that don’t have to be fractured at all, notable producers argue that experiments are paying off.
-
Over 1,000 hours of remotely monitored continuous production was achieved on an unmanned platform—a first for standalone offshore solids management in the North Sea.
