The use of 3C-3D seismic data channel sandstone
VO abnormal Channclw1) ln , i0 anonymous block diagram representation as an extension field of foreign oil and gas exploration and estimate the scope of this, the P-P-wave prestack data is broken down into nearly offset (c ~ 900m) and far-offset (1200m ~ 2iOOm). Then superimposed on these sub-data sets, and 3D offset signal to strengthen Figure 10a and Figure 10b is across the river near and far offset the time slice, Figure 10c is the difference between the two although we do not use the O inversion , n values, but comparison with Figure 9 can still clearly see the l O exception can be with the soldier,
abercrombie pas cher, the anomaly is relative to the Qiang. [-_}__ I was well-behaved wave A Ⅵ J Gu chu asked each dish on one column L | 1IJJ_l wave data set from the recent gun bolt superimposed Wei (surface 31) the results of partial Mu {(b) In addition to the use of far-offset foreign ,
christian louboutin france, Other (a same; t + c) is a circle (a] defect to the figure (b) the results of his wife as production wells heart black spots, (c) and store in the Arrow, said a total of 9 compared to the two unusual exceptions shift in the production wells west of the 150m or so of these anomaly maps using different methods of calculation that is the true anomaly maps show the physical effects of the river (bright spots) in the west of drilling wells is shown in Figure 7 based on the amplitude of PP trend, it does not predict / Vs anomalies. The next task is to Earthquake r / value is converted to clay content, Figure l1 is the gamma logs data and s chart with cokriging calculated mudstone percentage low according to our knowledge, is the first time in the ground over 3D exploration simultaneously 3T] Lu VSP VSP survey instrument in l2l6 five wells each instrument station on the record - about 50 gun record, recorded a total of seven equipment site. apparatus between stations and the hole upward along the small 75m. because there are many blasting work and surface seismic logistics have priority, so the ground will not put the gun,
abercrombie paris, although this process is complex (and, on balance), but get reasonable results, these results with ground data and synthetic data compare very well last, it is worth mentioning that so far no any oil Blackfoo * production, so its a very small change in reservoir conditions, we believe Figure 9 and Figure 10 shows that the current reservoir of abnormal physical state, and that these exceptions will be deposited in the first Glauconitic now we use the collected immediately after drilling the dipole sonic data to forecast r these exceptions, and this support r exploration and discussion of the value effect has concluded 3C3D seismic record is kind j] by the technology, which generates music kind of c if there is anisotropy. there may be three) on behalf of PP and PS data crossing the information of the independent body to provide it. -,
birkenstock paris, (Or Poisson's ratio) is particularly useful information. In Order No. 10, No. 6 using 3 ('3 D seismic data using gamma ray stripping channel sandstone well information (9 wells) and Figure 9, Figure V-base method according to co-Kerry counted mudstone Pocky presume this prince Yu . Putian main forecast indicates a total of 67 laps sandstone body 12 (a) brake well derivation of the PP-wave song Wei concluded as seismograms: (b) by the 3C2, D information to draw to teach according to the PP transition 0 P-P-wave analysis., ns data from the amplitude variation with offset inversion in the trend estimate. In contrast, 3C3D data can be directly calculated according to the conventional analysis of travel time This V / information we pre-juice 3C3D data collection, processing and interpretation costs cover more than the same number of conventional 3-D exploration of high-3O ~ 4O. However, an additional S-wave obtained additional information to help find the known oil production This information is closely related to abnormal development of several new instructions _r target. and perhaps avoid a few mouthfuls of dry wells translated 7'heLeadtngEdge.
