AB - ABSTRACT: This work describes the sedimentology, stratigraphy, diagenesis and reservoir quality of the El Dificil Limestone, and is oriented toward the optimization of hydrocarbon exploration and production in the area. The El Dificil Limestone is a calcareous sequence with a thickness of 600 feet in the Alejandria-1 well, and occurs at approximately 6000 feet in the Lower Magdalena Basin (Plato Sub-Basin), Colombia,. It is one of the calcareous members of the Cienaga de Oro Formation that were deposited on paleohighs as small rimmed-shelf platforms. Core and petrographic descriptions identified eleven facies: 1) coral reef (including rudstone, floatstone and framestone), 2) red/algae/foam-rich grainstone/packstone, 3) fine grained bioclastic packstone/wackestone, 4) rhodolith-rich packstone/wackestone, 5) coral/red algae packstone/wackestone, 6) Leptoseris-rich wackestone, 7) Globigerina ooze mudstone, 8) gastropod/foram wackestone, 9) calcareous sandstones, 10) conglomeratic calcareous sandstone, and 11) sandy limestone. These facies were deposited in seven main depositional environments: 1) shelf edge/reef edge, 2) shelf edge/grainy shoals, 2) slope apron to open shelf, 3) middle to open shelf, 4) paved ramp from shelf edge to slope apron, 5) peri-platform and 6) littoral to proximal lagoon. Two main reef zones and one bank-shoal, both completely cemented, were recognized in the shelf edge environment. Preliminary foram identifications date this sequence as Upper Oligocene. The diagenetic history of the El Dificil Limestone includes: 1) 100% stabilization from aragonite and high-magnesium-calcite to low-magnesium-calcite, 2) physical compaction that includes breakage and deformation of grains, and telescopic texture, 3) chemical compaction marked by a relatively high abundance of stylolitization and solution seams, 4) freshwater diagenesis that dissolved grains and matrix, creating vuggy porosity and microporosity, 5) mixing zone diagenesis that favored the occurrence of dolomite as isolated crystals or vug fills, and 7) late cements, typically sparry calcite filling vugs and microfractures. Seismic and core information enabled the identification of and three types of dominant stratigraphic settings: 1) platform flat, 2) slope, and 3) peri-platform/basin margin. The El Dificil Limestone is located at the edge of the platform flat. The sequence was deposited as a Transgressive Systems Tract and a Highstand Systems Tract, separated by a condensed section recognized in the core. In general, the platform shows a tendency of dipping towards the west and northwest, with a sharp edge to the south and a lost portion to the east due to strike-slip faulting. Reservoir quality of the El Dificil Limestone is moderate to low, due mainly to post-depositional compaction (physical and chemical) and the emplacement of late cements. Enhancement of porosity is attributed to leaching processes and vertical microfracturing caused by the influence of meteoric diagenesis that occurred before the drowning of the carbonate sequence by the marine shales of the Porquero Formation. Leached zones are more common and thicker toward the top of the formation. Differential compaction created highly crystalline zones that are very well recognized in the resistivity logs. Spontaneous potential and gamma ray logs do not respond to any recognized petrophysical parameter, so they are not useful tools for correlation in the carbonate platform. Plots of the different petrophysical parameters show that there is some control of the facies over the reservoir quality. Microporosity is a dominant factor in leached zones. Permeabilities are low (2 md) but still favor the production of natural gas and condensates. The absence of commercial hydrocarbons in the Alejandria-1 well is explained by a combination of factors determined by stratigraphic position and formation damage. Two potentially hydrocarbon-rich zones were delineated towards the north and south of the Alejandria-1 well site.

AB - ABSTRACT: A high resolution sequence stratigraphic study using 2300 feet of core calibrated with geophysical logs from 14 wells and 1800 measurements of porosity and permeability established the 4-D stratigraphic architecture and facies distribution and the 3-D reservoir zonation of the Mirador Formation in the Cusiana Field area. The most common reservoir-quality rocks are trough cross-stratified sandstones and pebbly sandstones of channel facies successions in the lower Mirador and of channel and bay-head delta facies successions in the upper Mirador. The geometry, continuity, volume and petrophysical properties of facies and facies successions change regularly as a function of their stratigraphic position. Two long-term stratigraphic cycles constitute the Mirador Formation in the Cusiana Field area. The lower long-term cycle comprises three intermediate-term, landward-stepping stratigraphic cycles. Cycles I and II are base-level rise asymmetrical, whereas cycle III is mere symmetrical. These intermediate-term cycles are composed of, in stratigraphic order, channel, crevasse splay and lake facies successions of the coastal plain facies tract. This trend of facies indicates base-level rise or increasing accommodation-to-sediment supply (NS) ratio. The change in symmetry, the increasing ratio of take and crevasse splay to channel facies successions and the continuous onlap of the intermediate-term cycles record base-level rise of the lower long-term cycle. Strata representing base-level fail time of the lower long-term cycle are continuous lake and floodplain mudstones in the Cusiana field, and are known as the Middle Mirador Mudstone. The lower long-term cycle ended with a time of subaerial exposure and valley incision that creates an erosional relief of at least 50 feet in the Cusiana field area. The upper long-term cycle comprises four intermediate-term, landward-stepping approximately symmetrical stratigraphic cycles. These intermediate-term cycles are composed of, in stratigraphic order, channel, bay-head delta and bay-fill facies successions of the bay facies tract. This facies succession indicates a base-level rise, whereas the reverse transition represents a base-level fall. Trough cross-stratified facies of channel facies successions in the lower long-term cycle and of channel and bay-head delta facies successions in the upper long-term cycle are the main reservoir rocks in the Mirador Formation. Crevasse splay, lake and floodplain facies successions in the lower long-term cycle and bay-fill facies successions in the upper long-term cycle constitute fluid-flow retardants or barriers at the time scale of reservoir production, Petrophysical data establish that permeability of good reservoir rocks is, at least, two orders in magnitude higher than of poor reservoir rocks, and that porosity in good reservoir rocks is 2 to 3% higher than in poor reservoir rocks. Sixteen reservoir zones were defined in the Mirador Formation. Reservoirs within the upper and lower long-term cycles are separated by the continuous Middle Mirador Mudstone which creates two large reservoir divisions. At the second level of zonation, the reservoir compartments and fluid-flow retardants or barriers coincide with the intermediate-term stratigraphic cycles. A third level of reseroir compartmentalization follows the distribution of facies successions within the intermediate-term cycles. A strong stratigraphic control of porosity and permeability was identified at three scales of stratigraphic cyclicity. In all cases as accommodation-to-sediment supply ratio increases porosity and permeability decrease, whereas porosity and permeability increase as this ratio decreases. Zone Ia, IIa, IIIa, Va, and Vc are fluid-flow compartments. Zones Ib, IIb, IIIb, Vb, VIa, VIb and VIc are fluid-flow retardants or barriers at the time scale of reservoir production. Zones Ic and IV are barriers. And finally zones VId and VII are retardants in some areas of the Cusiana Field and fluid-flow compartments in other areas.
