<\/p>\nSince receiving all the final data processing deliverables from EarthSignal Processing in Calgary, Canada, Invictus has been interpreting the newly acquired seismic data of the 2021 Cabora Bassa 2D Seismic Survey, as well the concurrently reprocessed data of the 1990 legacy Mobil dataset.<\/p>\n
The interpretation is now largely completed and Invictus is pleased to confirm the following key outcomes:
\n\u2022 The large anticlinal Mukuyu Prospect (previously named Muzarabani) has been confirmed with prospectivity, including extensive seismic anomalies identified at
\nmultiple levels.
\n\u2022 Substantial new shallow target identified in the Post Dande horizon in Mukuyu
\n\u2022 A well location and a preliminary well trajectory has been developed for Mukuyu-1
\nwhich will target all key levels.
\n\u2022 11 major seismic horizons mapped
\n\u2022 An extensive array of Prospects and Leads has been identified along the basin margin,
\nmany of which are supported by anomalous seismic amplitude behaviour and the
\ninterpretation is being matured.
\n\u2022 Invictus will continue to assess each of the basin margin prospects and select the most
\nsuitable candidate to be drilled as the second well in the 2022 drilling campaign.<\/p>\n
Substantial new shallow target in Mukuyu Prospect (previously Muzarabani)
\nA very positive and encouraging amplitude anomaly association for the Mukuyu Prospect has emerged from the new CB21 Survey data and the reprocessed vintage data. The previously identified Post Dande Lead A, which was evident on a single vintage seismic line (90-MZH013), has now been extensively covered by multiple lines from the CB21 Survey and revealed an additional and material shallower target in the Mukuyu Prospect at the Horizon 200 Level (Post Dande).<\/p>\n
The extent of the amplitude anomalies (up to 16km along strike and 15km along dip) are
\ncoincident with the greater structural closure at the Horizon 200 Level (Post Dande) and shown in Figure 1. The amplitudes terminate at approximately the same two-way time (TWT) across all the dip and strike lines which may indicate the presence of trapped hydrocarbons across the broader structure.<\/p>\n

When these anomalies are extracted from along the interpreted horizon on which they lie, and then gridded and displayed as an overlay colour grid on the depth contour map for that particular horizon (200 Level), there is a remarkable fit to structure whereby the anomalous amplitudes, shown by the red colour in Figure 3, appear to extend down to, but not beyond the highlighted green contour.<\/p>\n

This coincidence of anomalous amplitude with fit to structure is regarded as a very strong
\nattribute for any prospect and a potential Direct Hydrocarbon Indicator (DHI).<\/p>\n

Furthermore, a Lambda-Rho seismic inversion display (Figure 4), which can be used to
\ndistinguish rock and fluid properties, demonstrates gas prone indicators (lighter colours) which also shutoff at approximately the same two-way time across the structure.
\nHowever, it should be noted that the seismic data and amplitude anomalies are uncalibrated as the Cabora Bassa basin to date has not been drilled.<\/p>\n

All levels mapped show similar extensive 4-way dip closure.<\/p>\n A deviated well is being planned to test the Mukuyu prospect at multiple target levels along the well path on the southern flank of the structure as shown in Figure 5. Primary Target levels (A to D) are highlighted, however, there are potentially others that may not necessarily exhibit anomalous amplitude character.<\/p>\n Preparations to commence wellpad construction and civil works are well advanced with the contract awards completed and site surveying underway<\/p>\n Figure 5 – Mukuyu-1 (Muzarabani) Planned Well Trajectory & Primary Targets<\/p>\n The Mukuyu Prospect (formerly named Muzarabani) has been adopted to follow a new
\nThe Mukuyu Prospect (formerly Muzarabani) has been clearly delineated as a large, robust, 4-way dip anticline. This is most evident on the dip and strike lines inFigure 4. The positions of these seismic lines are referenced on the depth map for one the key target levels (the purple horizon 500 on the seismic lines in Figure 4) and the proposed location for the Mukuyu-1 well.<\/p>\n![\"\"](\"https:\/\/i0.wp.com\/www.oilnewskenya.com\/wp-content\/uploads\/2022\/04\/Mukuyu-Prospect-4.png?resize=607%2C285&ssl=1\")
