1 Oil and Gas Research Institute Seismic Analysis Center Faults Detection Using High-Resolution Seismic Reflection Techniques Ghunaim T. Al-Anezi (KACST) March
2 Objectives The objective of the survey was to locate faults and to map the bedrock up to the depth of m. The survey covered 3 lines of high-resolution seismic reflection with a total length of 282 m in Salboukh, about 50 km towards north from Riyadh city. 2
3 Location The study area is located about 50 km north of Riyadh city. Figure 1: diagram of geophone array development and shot locations used for the acquisition of seismic CMP line. The geophone spread consists of 48 receivers spaced 2 m apart. 2 receiver lines spread and three source lines shoot. Source lines 1 and 2 shoot at 4 m offset from receiver line 1 either side and source line 3 shoots at 4 m offset from receiver line 2. 3
4 The seismic method represents one of the most important geophysical techniques for oil and gas exploration due to its high accuracy, high resolution, and deep penetration. On relatively smaller scale, this method can also be applied to groundwater searches, environmental and civil engineering investigations and to some extent in mineral exploration. During the past 30 years, the growing interest in engineering and environmental problems has increased the application of seismic reflection surveys to study shallow targets of hydrogeological, engineering, environmental, archaeological, and geotechnical aspects. 4
5 The main challenge in using high resolution shallow seismic data for estimating the near surface features is the maintenance of the high frequencies reflections from shallow interfaces in the face of attenuation and possible aliasing. In order to acquire high resolution seismic data for shallow subsurface investigation, spacing between source and receiver must be perfect enough to ensure un-aliasing of the data. Frequencies for high resolution acquisition can reach up to 500 Hz. 5
6 Seismic data acquisition Three seismic profiles for high resolution reflection are conducted in the study area. Figure 2 : Seismic data acquisition system 6

16 Line 1 Reflection line 1 length is 94 m; its direction is SW-NE. In this line, the bedrock depth is ranging from m (Figure 11). A big fault noticed on the right portion where the portion of bedrock is uplifted to be at 18 m depth. The frequency of the data is a bit on the lower side that s maybe due to the energy penetration problem or attenuation in the complexity or heterogeneity of the near surface. reflection line 3 cross reflection line 1 and the time of the bedrock layer matched which gives enough confidence in saying that this is the true image of bedrock. 16

19 Line 2 Reflection line 2 length is 94 m; and its direction is NE-SW and is running parallel to reflection line 1. This line is just 8 m away from Reflection line 1 so it will follow almost same subsurface structure. In this line, the bedrock depth is ranging from m (Figure 13). A big fault noticed on the right portion where the portion of bedrock is uplifted to be at 18 m depth. The frequency of the data is a bit on the lower side that s maybe due to the energy penetration problem or attenuation in the complexity or heterogeneity of the near surface. The signal to noise ratio is not that good here as it was in reflection line 1 but it is conforming the same structure. Reflection line 2 was also crossed by reflection line 3 shows the same time of bedrock at crossing. 19

21 Figure 13 : final stack of reflection line 2 in depth (time to depth converted with final velocity model) 21
22 Line 3 Reflection line 3 also shows the same depth range of bedrock, that is 18 to 25 m (Figure 15). Reflection line 3 length is also 94 m; its direction is NW-SE and is crossed by reflection line 1 and Reflection Line 2. The Fault is not obvious in this line but it is following a synform shape. Again the frequency content looks lower but as long as it is mapping the bedrock, the worries remain away. The maximum offset was very small, so we cannot expect anything else at deeper depth. The high frequencies attenuate very fast in near surface due to its heterogeneity. The signal to noise ratio is good up to the desired objective. 22

25 Conclusions and Recommendations The high-resolution seismic reflection technique has been shown to be useful for mapping the bedrock. This study was initiated with acquiring 2D high-resolution seismic reflection data over about 282 m line length consisting of 3 seismic lines. The results show that the bedrock lies at about m depth and some faulting observed in seismic reflection data. It seems that imaging depths shallower than 20 m is still a great challenge. 1- In order to obtain an improved image of subsurface features in the study area, the use of 3D - high resolution seismic reflection method is strongly recommended. 2- Additional information about the local up-hole lithology from the oil companies can significantly improve the level of interpretation in any future geophysical endures. 25
