Liaohe Depression

GC and GM-MS experiments are exerted for 34 oil samples in shallow water area of Liaohe Depression. The results show that Gas chromatograms are clear, continuous and intact which means the bio-degradation can be ignored. Originally the sediments are mainly deposited under oxidization environment. The oil resource is composed by the bacteria, aquatic organisms and higher plans. The depositional environment changes from reductive type to oxidization in the W-E direction. The salt content is high. From Lingnan well area in the west to Kuihua well area in the east the oil maturity increases. According to the depositional environment, source rocks and maturity features the oil samples are divided into 3 types. A is located in the west and centre of study area and Gammacerane index is less than 0.2. B in the centre and east. A and B are different in the organic import degree. To be specific the A is mainly supported by aquatic organisms while the B by continental materials. C has high gammacerane of more than 0.55, which comes from salt water environment.

As the escalating hotspot and key object of hydrocarbon exploration, research of shallow-water delta deposits in China have made breakthrough in both in production and efficiency. Numerous results in Bohai Bay Basin show that the conditions of shallow-water delta sandbodies are widespread in late Paleogene and Neogene. In this paper, we analyzed the geological evidences, deposition microfacies and favorable reservoir conditions from structural phases, palaeontological characteristics, depositional characteristics and geophysical characteristics (stacking patterns of wireline logs and seismic reflection characteristics). The results indicate that shallow-water delta deposits usually develope in shallow-water area where exits flat and broad terrain, arid and hot paleoclimate, turbulent lake level and ample provenance. As for the reservoir conditions, rivers brought large amounts of organic matter and minerals into the lake, which aided in bringing up organisms. All these organisms provided basis for petroliferous source rocks. The mudstone layers developed above the shallow-water deposits which helped to form vertical patterns of reservoirs. These conditions determine that shallow-water delta deposits consist of excellent reservoir combination, various types of traps, sufficient source rocks, smooth migration pathways, which provided broad exploration prospects.

In this paper, analysis of directional wave spectra in shallow water area estimated by video images data has been compared with numerical model of SWAN. Estimation of directional wave spectra from video images is based on the Bayesian Directional Method using a group of pixels brightness on the image. For this study, the pixels can be considered equivalent to fixed instruments as wave probe sensor after rectification process. The results show that there is a good agreement between directional wave spectra estimated by video images data and the SWAN model. Both methods estimate similar shape of directional wave spectra in the shallow water. In addition, the energy distribution of directional wave spectra in shallow water is concentrated significantly in frequency and direction.

Over the years, the acquisition technique of bathymetric data has evolved from a shipborne platform to airborne and presently, utilising space-borne acquisition. The extensive development of remote sensing technology has brought in the new revolution to the hydrographic surveying. Satellite-Derived Bathymetry (SDB), a space-borne acquisition technique which derives bathymetric data from high-resolution multispectral satellite imagery for various purposes recently considered as a new promising technology in the hydrographic surveying industry. Inspiring by this latest developments, a comprehensive study was initiated by National Hydrographic Centre (NHC) and Universiti Teknologi Malaysia (UTM) to analyse SDB as a means for shallow water area acquisition. By adopting additional adjustment in calibration stage, a marginal improvement discovered on the outcomes from both Stumpf and Lyzenga algorithms where the RMSE values for the derived (predicted) depths were 1.432 meters and 1.728 meters respectively. This paper would deliberate in detail the findings from the study especially on the accuracy level and practicality of SDB over the tropical environmental setting in Malaysia.
