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 Ormen Lange since 2012. Gravimetry measurements detect mass changes in the
“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 AS. Ruiz spoke at The Biennial Geophysical seminar 2020 hosted by Norsk Petroleumsforening (NPF). Read the full text at expronews.com .
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
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
OCTIO’s DepthWatch technology is used to determine relative seafloor depths with extreme accuracy. Thanks to recent developments that make the instrumentation even more precise and compact, DepthWatch is now available as a service for ocean bottom node (OBN) seismic campaigns. The development will be presented by Paul Hatchell (Shell) at the forthcoming SEG Conference (see the abstract here). 4D OBN surveys are performed periodically over
OCTIO has surveyed this summer the Snøhvit, Albatross and Askeladd gas fields, operated by Equinor Energy AS. The survey featured the gWatch technology, the new generation of seabed gravity and subsidence instrumentation. The operation lasted for less than three weeks and was performed very efficiently and with no HSE incidents. In this type of surveys, the quality of both gravity and seafloor depth data is

Equinor Energy AS has awarded OCTIO an exclusive contract for gravimetric monitoring on the Norwegian continental shelf. The contract has an initial duration of five years, with an option of additional four years. For these surveys, OCTIO will be utilizing gWatch, the new generation of seabed gravimetry equipment. gWatch was introduced in 2018 for the surveys of the Ormen Lange and Aasta Hansteen fields, and
OCTIO will be present at the SEG exhibition and conference in Anaheim, California, 14-19 October 2018. Come and visit us at booth 1943 and discover our new products: DepthWatch: full-field seafloor subsidence monitoring to indentify undepleted compartments and prevent geohazards gWatch: 4D gravity at the seafloor as an alternative to seismic at a 10% cost DrillWatch: real-time seismic look-ahead during well drilling, for faster drilling
