Well integrity/control
Prior to proceeding with a contract to fulfil a rigless P&A campaign for Sasol in Mozambique, BiSN designed a field trial to prove the effectiveness of its bismuth plug technology. Although the technology had been used in 19 countries by BiSN for a variety of downhole applications, it had not yet been qualified for use in Mozambique.
Over a 10-year period, sensors monitoring the motion and loads near subsea wellheads have been mounted on more than 300 drilling campaigns. Integrity parameters were calculated to assess whether subsea conductors provided the intended amount of support during drilling operations. In several of these campaigns, loss of conductor support due to integrity issues was obse…
This paper describes the material selection methodology and corrosion studies performed in a CO2 sequestration project to optimize well costs and improve overall project economics without jeopardizing the CO2-injector-well integrity.

This paper presents an intelligent tube solution that combines data retrieved by the sensors with the actual resistance of each pipe in the well to allow adjustment of production parameters while ensuring installation safety. -
This paper introduces a method using a Bayesian network to aggregate trends detected in time-series data with events identified by natural language processing to improve the accuracy and robustness of kick and lost-circulation detection.

Diagnostics firm TGT launched its newest acoustic platform that it says broadens flow analysis by adding radial distance to the data collected.
-
The second phase of the project will analyze data gathered in Phase 1, with the goal of improving riser, wellhead, and conductor fatigue estimates.
-
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.

EcoShield also reduces carbon footprint of well construction over traditional cement systems.
-
The authors of this paper describe the development of a continuous monitoring solution throughout its deployment.

Moving into 2023, perhaps it will be safe to say that the era of the low-carbon energy mix has begun as the primary energy production landscape is changing fast. Until now, fossils fuels have dominated, and may still for the next few years dominate, the energy mix; however, a shift is taking place that will gain momentum, driven by global efforts toward addressing cli…

The authors of this paper describe a software technology that balances calculated well-integrity risk with the associated financial impact for an entire integrity-surveillance program.
