UKOOA phase II Task 3: Aerobic and anaerobic degradation of drill cuttings – results from small scale laboratory experiments
Kjeilen, Grethe; Torgrimsen, Sigfryd; Øysæd, Kjell Birger; Jonsson, Grete; Brakstad, Odd-Gunnar (Research report, 2001)The main goal of the small-scale biodegradation experiment series was to obtain biodegradation rates of THC in drill cuttings material, at conditions partly realistic for in situ drill cuttings accumulations. Both aerobic ... -
UKOOA Phase II Task 3: Simulated bioturbation of drill cuttings – results from small scale laboratory experiments
Tvedten, Øyvind F.; Torgrimsen, Sigfryd; Kjeilen, Grethe (Research report, 2001)Bioturbation can influence many of the characteristics of sediments, including their stability, microbial activity and degradation rates of contaminants. This study addresses the effects of mechanical disturbance, resembling ... -
UKOOA Task 3: Colonisation and macrofaunal activity in drill cuttings material – results from small scale laboratory experiments
Woodham, Annette; Tvedten, Øyvind F.; Eriksen, Veslemøy; Torgrimsen, Sigfryd; Kerr, Juliana; Kjeilen, Grethe (Research report, 2001)This report presents the results from a laboratory experiment addressing colonisation and bioturbation of drill cuttings material. The work forms a sub-task of Task 3 of the UKOOA Drill Cuttings JIP phase II Task 3 and has ...
