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

12April2021

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

2March2021

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

8January2021

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

6October2020

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

9July2020

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

6July2020

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

4June2020

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

26March2020

“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 expronews.com .

Superior well navigation and geo-steering with OCTIO DrillWatch

27November2019

Offshore drilling is a costly and complex operation. In order to successfully achieve well-objectives and ensure maximum value from production, operators must make timely and informed decisions throughout the drilling process. With OCTIO DrillWatch, operators can avoid costly interruptions and avoid previously unforeseen hazards through improved navigation of the drill bit. While existing methods for tracking the drill-bit during drilling suffer from uncertainties that increase

OCTIO to unveil seismic-while-drilling look-ahead results at the SEG Annual Meeting

10September2019

Drilling operations are planned based on seismic data and reservoir models. But even when best possible data are available, faults can remain unresolved and hazardous features like karst cavities can come as a surprise. The navigation of the drill bit with respect to the reservoir itself can sometimes remind of a walk in the fog, due to uncertainties in the velocity model. OCTIO’s DrillWatch technology
