“…The depositional environments control the spatial distribution of the dominant lithofacies types along the depositional delta and shoreline systems, which in turn, plays the main primary factors in reducing or enhancing the reservoir quality (El‐Ghali, El Khoriby, Mansurbeg, Morad, & Ogle, ; Nabawy & El Sharawy, ; Sallam et al, ). For the studied lithofacies types in both Wadi Wasit and Sarbut El Gamal, the limestone lithofacies, including the laminated argillaceous limestone (LF2') mudstone (LF2) and the fossiliferous marly limestone (LF3), represent the lowest quality (Ranks 5 and 6; Table ).…”

The Lower Miocene Rudeis Formation has been studied in two surface outcrops on the eastern onshore of the Gulf of Suez at Wadi Wasit and Sarbut El Gamal localities and in the subsurface sequence of October oil field in the central part of the Gulf of Suez. A correlative study between the subsurface sequence and its surface analogs was carried out to assess the reservoir quality of the Rudeis Formation and the impacts of the lithofacies, microfacies, pore types and dominant diagenetic processes on its reservoir quality. The Rudeis Formation consists of a thick carbonate-clastics succession. The lower part consists of a cyclic sequence of laminated, fossiliferous and argillaceous limestone intercalated with mudstone, and sandstones. These units are unconformably overlain by alternations of conglomerate, coarse sandstones, and limestones. It is documented that the clastic microfacies have good reservoir quality in the October Field and poor quality in Wadi Wasit. This is due to the impacts of dissolution and fracturing diagenetic processes. The carbonate microfacies are impervious due to effects of cementation, mechanical compaction, quartz overgrowth, authigenic minerals, and micritization.

“…The stratigraphic units in the Gulf of Suez can be subdivided into three mega sediment groups (Fig. 2): (1) the Cambrian-Oligocene pre-rift sequence; (2) the Oligocene-Miocene syn-rift sequence (the core of the present study), which comprises the main hydrocarbon reservoirs as well as seals in the Gulf of Suez (Nukhul, Rudies, Kareem, Belayim, South Gharib, Zeit, and post-Zeit seals and reservoir rocks); and (3) the post-rift post-Miocene mega-sequence (Bosworth and McClay 2001;Attia et al 2015;Nabawy and El Sharawy 2015;Abudeif et al 2016aAbudeif et al , 2016bAbudeif et al , 2018; Radwan Egypt (EGPC 1996). et al 2019b, 2020aKassem et al 2021).…”

“…The Hammam Faraun member is a stacked alluvial fan delta system deposited in a shallow marine environment. It is composed of shale interbedded with sandstone beds and thin carbonate beds (Khalil and Meshrif 1988;Rashed 1990;EGPC 1996;Hughes et al 1997;Gawad et al 1986;Alsharhan 2003;Jackson et al 2006;Radwan 2014;Nabawy and El Sharawy 2015;Ali et al 2016;Nabawy and Barakat 2017;Abudeif et al 2018;Radwan et al 2019a;Radwan 2020d).

Implementation of Rock Typing on Waterflooding Process During Secondary Recovery in Oil Reservoirs: A Case Study, El Morgan Oil Field, Gulf of Suez, Egypt

Waterflooding is one of the most common secondary recovery methods in the oil and gas industry. Globally, this process sometimes suffers a technical failure and inefficiency. Therefore, a better understanding of geology, reservoir characteristics, rock typing and discrimination, hydraulic flow units, and production data is essential to analyze reasons and mechanisms of water injection failure in the injection wells. Water injection failure was reported in the Middle Miocene Hammam Faraun reservoir at El Morgan oil field in the Gulf of Suez, where two wells have been selected as injector’s wells. In the first well (A1), the efficiency of injection was not good, whereas in the other analog A2 well good efficiency was assigned. Therefore, it is required to assess the injection loss in the low efficiency well, where all aspects of the geological, reservoir and production data of the studied wells were integrated to get a complete vision for the reasons of injection failure. The available data include core analysis data (vertical and horizontal permeabilities, helium porosity, bulk density, and water and oil saturations), petrographical studies injection and reservoir water chemistry, reservoir geology, production, and injection history. The quality of the data was examined and a set of reliable X–Y plots between the available data were introduced and the reservoir quality in both wells was estimated using reservoir quality index, normalized porosity index, and flow zone indicator. Integration and processing of the core and reservoir engineering data indicate that heterogeneity of the studied sequence was the main reason for the waterflooding inefficiency at the El Morgan A1 well. The best reservoir quality was assigned to the topmost part of the reservoir, which caused disturbance of the flow regime of reservoir fluids. Therefore, it is clearly indicated that rock typing and inadequate injection perforation strategy that has not been aligned with accurate hydraulic flow units are the key control parameters in the waterflooding efficiency.

“…The diagenetic processes have either reservoir qualitydeteriorating or enhancing implementation on the reservoir rocks. The reservoir quality-deteriorating features can be discriminated into physical and chemical compaction, cementation, and predominance of authigenic minerals, while the quality enhancing factors can differentiated into dissolution and fracturing as stated in many literature (Nabawy and El Sharawy, 2015;El Sharawy and Nabawy, 2016;El Sawy et al 2020;Nabawy et al 2020b;Abuhagaza et al 2021).…”

In this study, it is aimed to characterize the Early pliocene sandstone (EP-SD) and the Late Miocene-Early Pliocene Mangaa sandstone reservoirs and the efficiency of their sealing cap rocks using the petrographical and petrophysical data of these sandstone zones in northern Taranaki basin, New Zealand. The prospective potential reservoirs were studied using impregnated thin sections, XRD data analysis, and well log data (self-potential, gamma-ray, sonic, density, neutron, shallow\deep resistivity and PEF) to characterize the reservoir zones, in addition to Mercury intrusion capillary pressure data (MICP) to check the efficiency of some potential seals. The EP-SD and the Mangaa sandstone units are typically poorly consolidated very fine sandstone to siltstone, with porosities averaging 25%. The sands are composed of quartz (38.3–57.4%), with common feldspars (9.9–15.2% plagioclase, and 2.7–6.3% K-feldspars) and up to 31.8% mica. In Albacore-1 well to the north of the Taranaki Basin, the Mangaa formation includes three separate for each of the EP-SD zones (EP-SD1, EP-SD2, and EP-SD3), and the Mangaa sequence (Mangaa-0, Mangaa-1, and Mangaa-2). The thin section studies indicate that, the studied samples are grouped into greywackes, arenites and siltstone microfacies with much lithic fragments and feldspars, sometimes with glauconite pellets. From the XRD data, it is achieved that the mineral composition is dominated by quartz, mica/illite, feldspars, and chlorite. The petrophysical investigation revealed absence of pay zones in the EP-SD zones, and presence of thin pay zone with net thickness 5.79 m and hydrocarbon saturation of about 25.6%. The effective porosities vary between 23.6 and 27.7%, while the shale volume lies between 12.3 and 16.9%. Although the shale content is relatively low, the relatively high API (50–112 API of average 75 API) is contributed by the relatively high K-feldspar content and intercalations with thin siltstone and muddy siltstone beds. Sealing units include the intra-formational seals within the Mangaa sequence, mudstones and fine grained units overlying the Mangaa and further intra-formational mudstones, within the shallower EP-SD units. The efficiency of these seals indicates the capability to trap 16.4–40.6 m gas or 17.4–43.0 m oil which is relatively low in correlation with their efficiency in the central parts of the Taranaki Basin Overlying the primary seals, mudstones of the Giant Foresets Formation provide additional regional seal.
