Reach Subsea ASA acquires OCTIO & MonViro

Haugesund, 8 December 2021: Reach Subsea ASA (“Reach”), a provider of subsea services globally, today announced that the Company has entered an agreement with Equinor Ventures AS to acquire OCTIO AS. “The acquisition of OCTIO will deepen Reach Subsea’s technology competence and expand our value chain, accelerating the Company’s strategy to become a full-service provider of subsea data and solutions for clients globally,” said Jostein

OCTIO completes 4D gravimetry survey for Equinor’s giant Troll field

OCTIO has successfully completed the gWatch survey acquired over the giant Troll field. The operation was conducted using the Havila Subsea vessel and was completed with unprecedented efficiency with no equipment downtime. The average uncertainty for the measurements for the survey was 0.5 µGal and 2.1 mm. Equinor uses 4D gravity and subsidence data to optimize the field production. At Troll, results from previous surveys

OCTIO presents the impact of the new generation of gravimetry & subsidence instrumentation

During the 2021 EAGE PRM workshop, OCTIO presented results demonstrating the improved gravity and subsidence monitoring accuracy with the gWatch instrumentation. The OCTIO and Equinor authors (abstract) utilised the Snøvhit gas field monitoring case to demonstrate enhanced data value to our customers with the abovementioned improvements. During a survey, OCTIO gWatch measures gravity and subsidence at predefined locations (stations) at the seafloor. OCTIO conducts repeat

OCTIO sets a new milestone for accuracy and efficiency of gravimetry surveys with Shell Norge at Ormen Lange field

OCTIO completed the 7th gWatch survey for Shell Norge and delivered outstanding quality gravimetry and subsidence measurements at the Ormen Lange field. Shell Norge acquires gravimetry and seabed subsidence measurements at Ormen Lange field every second year to monitor aquifer influx, reservoir compaction and the energy balance within the reservoir. Shell Norge uses these measurements to refine field recovery strategy and increase gas production sustainability. 

OCTIO awarded contract for DrillWatch service

OCTIO Gravitude has been awarded a contract by Lundin Energy Norway for deploying OCTIO DrillWatch service at the upcoming exploration well 16/4-12 Merckx in the Production License 981. DrillWatch has the potential to improve operational efficiency and safety. With look-ahead measurements, DrillWatch significantly reduces depth uncertainty of formation reflections ahead of the bit and supports the landing of the liner shoe in the target interval.

MOL Norge and Innovasjon Norge engage in the further development of the OCTIO DrillWatch technology

MOL Norge has decided to deploy OCTIO DrillWatch technology for the upcoming exploration well 2/9-6 S in the PL617 block. DrillWatch has the potential to improve operational efficiency and safety for MOL Norge. With look-ahead measurements, DrillWatch can significantly reduce depth uncertainty of formation reflections ahead of the bit. The project has been made possible through funding from Innovasjon Norge. “The OCTIO team thanks MOL

OCTIO Gravitude kicks off the 4D gravimetry survey of the Midgard and Aasta Hansteen fields

OCTIO Gravitude has recently kicked off the offshore surveys that will acquire seabed gravity and subsidence data over the Midgard and Aasta Hansteen fields. The operation started July 1st, with the mobilization of OCTIO Gravitude’s equipment on the Subsea Havila vessel in Haugesund (Norway), and is expected to last for three weeks. Equinor uses 4D gravity and subsidence data to increase recovery rates and manage

OCTIO secures a maintenance contract extension with Equinor for WellWatch system on Oseberg C

OCTIO has secured a one-year contract extension with Equinor to provide maintenance services for the WellWatch system on the Oseberg C platform. OCTIO deployed the WellWatch seismic cable on the seabed, and Equinor utilizes the data acquired for continuous monitoring of an injector well for the cuttings waste injection program. This monitoring ensures caprock integrity while maximizing injection rates. The benefits of a robust surveillance

OCTIO Gravitude awarded gravimetry survey for the Ormen Lange field

OCTIO Gravitude will survey the Ormen Lange field during summer 2020. Ormen Lange is the second-largest gas field in Norway and has been in production since 2007. The operation is expected to last for four weeks and will produce measurements of water depth and gravitational field at the seabed above the gas reservoir. Seabed gravimetry and subsidence measurements have been acquired every second year at

Secure high recovery rates under challenging oil prices with gWatch

“In some fields, ocean bottom gravity and subsidence measurements are working better than seismic surveys at a fraction of the cost when it comes to reservoir monitoring,” said Hugo Ruiz, Vice President G&G at the Bergen-based company OCTIO Gravitude AS. Ruiz spoke at The Biennial Geophysical seminar 2020 hosted by Norsk Petroleumsforening (NPF). Read the full text at .
