| Hi, I am interested in your study on the Gullfaks oilfield. You know Gullfaks in going to be depleted, maybe we should stop and remove the platforms. But I think before doing that, it’s better to think about the geometry of the reservoir. I have seen that the water injection wells are against the flow geometry, I mean the injected water, pushes the oil back from the wellbore, the watercut becomes higher and when we stop injection, then oil production increases and watercut decreases. We should start an injection well at the southern part of Gullfaks. It’s better to allow the reservoir to increase its pressure by a build up, then start injection from the southern part. Actually there is no platform at that part but I think that drilling a side track is possible with the original platforms. Ok, good luck. Abdi, MSc in Petroleum Engineering, NTNU. |

| Could you please explain to me the sulfonation process for enhanced oil recovery. Is naphthalene and 2-methylnaphthalene used in this process? In water injection or CO2 injection or both? |

| Jane - I recommend you read Chapter 7 (Chemical Flooding) of Enhanced Oil Recovery by Don W Green and G Paul Willhite - SPE (Society of Petroleum Engineers) Textbook Series Volume 6, 1998 (ISBN - 1-55563-077-4). This has information on the use of sulfonates for EOR. Sulfonates are added to the water. |

| This article was very interesting and is helping me a lot for my group year project for the design of a CO2 carrier for the north sea. If more information is available about the sequestration of CO2 and the carriage of it by ship I would really like to read it. Thank you |
