“We used Heavelock Solutions on two occasions: for well planning on the Wisting field in the Barents Sea and on Hades/Iris in the Norwegian Sea... We plan to conduct drilling operations all year around in the Barents Sea. It is thus important for us to be on top of things and know in advance what kind of consequences rig heave might have in our wells... Hades/Iris is a high-pressure high-temperature (HPHT) field and our goal here is to have as low mud weight as possible during drilling. But we cannot reduce the mud weight so much that we get problems related to surge & swab, induced by rig heave. Simulations from Heavelock Solutions help us to achieve better results in well engineering – we use them actively in our well design process and when we develop our operational procedures.”
