Coverage 88,7 % is acceptable: almost the whole horizon is sampled by at least one reflection (2.781 of 3.136 cells). Far-offset overrun. Mean depth is 920 m, so the design rule gives Xmax = 920 m, but the 95th percentile offset is 1.549 m (1,68x). Those steep rays will be muted by NMO stretch during processing. Consider capping the far offset and spending the recovered channels on fold instead. Only 0,07 % of rays exceed the critical angle, so illumination is dominated by genuine body-wave reflection. That is not a clean zero, though: p100 incidence is 59,4 degrees, still past the critical angle, so treat the head-wave share as contamination to be read rather than as an all-clear. Median azimuthal concentration R = 0,306 - reflection azimuths are well spread, so there is no directional shadow problem at this depth. A migration aperture of about 531 m is needed to focus this horizon (Z x tan 30). The survey must extend at least that far beyond the mapped area on every side.1PK K]:A*ppt/notesSlides/_rels/notesSlide1.xml.rels PK K]زyyppt/slides/slide2.xml TINJAUAN HORIZON | 2 DARI 3 TARGETMBE — Target Tengah · mean depth 1.213 m88,7 %COVERAGE HORIZON2.781 dari 3.136 sel ter-sampel2.008 mOFFSET P95aturan desain 1.213 m1,42 %LEWAT SUDUT KRITISinsidens p100 78,8°0,258KONSENTRASI AZIMUTHpada median, makin kecil makin tersebarTEMUAN — OVERRUN FAR-OFFSET1,66×Aturan desain Xmax ≈ Z memberi 1.213 m, sementara offset p95 sudah 2.008 m.
