Paper presented at the The Twenty-fourth International Ocean and Polar Engineering Conference, June 15–20, 2014
Paper Number: ISOPE-I-14-035
... Abstract An acidizing technology was applied to a carbonate reservoir oil field in Iraq. The oilfield is located in the Southeast of Iraq, whose main production reservoirs have two intervals. Interval A mainly consists of dolomite, limestone and a little of sandstone whereas interval M mainly...

... were collected from the deployed DK-9 well. Compared with the soil acid extracted hydrocarbon, natural thermoluminescence is not subject to the bacterial gas and coal-bed gas of marsh, so it is considered as a new assistive technology for hydrate prospecting. anomaly thermoluminescence anomaly...

Paper presented at the The Twentieth International Offshore and Polar Engineering Conference, June 20–25, 2010
Paper Number: ISOPE-I-10-553
..., traditional rust removing methods such as grinding by hand, shoveling and sand blast and so on are very time-consuming. This paper presents a rust converter suitable for ocean vessel hull treatment, whose formulation is based on polyphosphoric acid and tannic acid. In order to improve the performance...
