The pores of many carbonate-cemented sandstones today available in the markets around the world at cheap price square foot contain minerals that bind the grains together. This is called mineral cement. Sandstones sometimes contain carbonate mineral cements that cause the rock to react with HCl. Carbonaceous cement sandstones can have all the grain structures seen in other sandstone types. Both types are coarser than normal gray sandstones of the same type. Calcite cement sandstones can be blue to gray in color and may be lightly stained. It is easily gasified with a little hydrochloric acid. Siderite cement sandstones are usually pink or reddish in color compared to the darker varieties, which evaporate into a powdery texture when formed. Flooding has long been a secondary mechanism for oil recovery. In recent years, extensive studies of crude oil, brine, and rock systems have shown that the injected water composition can effectively modify the hydraulic reservoir irrigation pattern to improve oil recovery. . . Thus, injection of "smart water" with appropriate concentration and salinity can serve as a tertiary recovery method. 
From an economic point of view, it is important to implement hydroflooding in the best-case scenario in the second option. Examples of sensible water injection into carbonates and sandstones are: (1) seawater injection into chalk reservoirs at high temperatures and (2) low salinity flooding in sandstone areas. The chemical mechanism of changes in composition of injected water has been a topic of discussion in carbonates and especially sandstones. In this article, the mechanisms proposed for the hydrolysis of the two types of fossil rocks are briefly reviewed, with particular emphasis on chemical similarities and differences. Different chemical adsorption patterns of solar components from crude oil to positively charged carbon and negatively charged quartz/clay suggest a different chemical mechanism to change the potential of smart irrigation in both cases. Authigenic carbonate cement is one of the most common diagenetic minerals in sandstone deposits. Identifying its source and distribution can provide valuable information to understand sandstone reservoir quality. In this study, we report the results of a suite of analytical techniques to investigate the origin and evolution of carbonate cements in the third part of the Shahejie Formation in the Bohai Bay Basin. Our data suggest that carbonate cements occur mainly in three phases: early-stage calcite, late-stage calcite, and late-stage ferroan dolomite and/or ankerite.

The price for carbonate cemented sandstone per square foot is around ₹ 120. Graphs are provided comparing average porosity versus average porosity. depth in 30,122 siliciclastic and 10,481 carbonate deposits covering all oil-producing countries except Canada. However, the different plots cover 5,534 siliciclastic and 2,830 carbonate deposits from the Alberta region of Canada. mean permeability vs. permeability. average porosity is shown for sites outside of Canada. Important similarities and differences between sandstones and carbonates are noted, and implications for the major factors controlling reservoir quality in each lithology are discussed. The trends of constant decrease in mean and maximum porosity with increasing depth reflect the loss of diagenetic porosity of the burial in response to increasing thermal exposure with depth. These trends appear inconsistent with suggestions that both sandstone and carbonate tend to increase in depth by melting during deep burial. Carbonate deposits are assigned lower values of median and maximum burial depths, likely due to higher chemical solubility of the minerals compared to quartz and quartz, resulting in less inhibition of chemical stress and associated synthesis. . The relative scarcity of low-porosity (0–8%) siliciclastic reservoirs at all depths compared to carbonates may reflect the greater occurrence of fractures in carbonates and the effectiveness of these fractures in facilitating economic flow rates in late rock. In general, carbonate reservoirs do not have lower permeability at a given depth compared to sandstones, but they do have significantly lower percentages of high porosity and high conductivity values. The data presented can serve as a general guide to the distribution of reservoir levels that can reasonably be expected in exploration wells drilled to any given depth in the absence of geological information, such as burial and thermal history. 
First-order calcites show a reduced δ18O of first-order calcite (−11.8% to −7.8%), suggesting a water source of reduced 18O from mixing between marine and meteoric waters. They precipitated earlier than the overgrowth of quartz at 40°C–63°C depending on the oxygen isotope. Late-phase calcites precipitated at 70°C–115°C, and originated from water-rock interaction modified pore water at the same time or later than feldspar leaching. They show a lower average δ13C value (1.27%) than that of early-stage calcite (1.65%), indicating that the cores containing chambers within the sandstones predominantly provide the necessary components for the precipitation of 1-stage calcite. after. Also, some Fe2+ was released during organic acid production and subsequent precipitation of late-stage ferroan calcites. Late-phase ferroan dolomite and/or ankerite precipitated at 90°C–137°C in intense diagenetic conditions. They show decreased δ13C values (mean −0.42%), and carbonates were mainly derived from thermal decarboxylation of organic matter and lacustrine carbonate. Primary calcite resists compression by filling pores, and the dissolution of ferroan calcite cements was the primary cause of secondary pore growth in sandstone deposits. Late-phase ankerite reduces the porosity of the reservoir. Isotope is derived from the Greek (meaning equal phases) and indicates that isotopes occupy the same position in the periodic table. Thus, isotopes are defined as atoms whose nuclei contain the same number of protons but a different number of neutrons[1]. Carbon has two stable isotopes 12C and 13C. Heavy carbon has a δ value greater than +20 and light carbon has a δ value of about -90. There are two methods of preparation and the gas used in all 13C/12C measurements is CO2. The first reaction is one in which carbons react with 100% phosphoric acid at temperatures between 25°C and 75°C to release CO2. The second process involves organic compounds that are generally heated at ~1000°C in a stream of oxygen or CuO.

The Ordos Basin of carbonate cemented sandstone which has blocks of various sizes per meter, square foot…is the second largest basin in China. The basin was part of the North China Craton before the Paleozoic, and became an isolated marine unit during the Middle and Late Triassic [3]. A series of clastic lacustrine and deltaic sediments, formerly known as the Yanchang Formation, were deposited during this period. The Upper Triassic Yanchang Formation, underlain by the middle Zhifang Formation and overlain by the Lower Jurassic Yanan Formation is the main oil-producing bed in the Ordos Basin. The Chang 8 sandstones (the eighth member of the Yanchang Formation), which consist of braided delta subaqueous distribution channels, are important reservoir components. However, the Chang 8 sandstones, which have undergone various types and degrees of diagenesis such as compaction and cementation by carbonates and clays, are fine-grained, low-permeability micro-pore deposits , and high microscopic heterogeneity (Zeng and Li 2009);. The Bohai Bay Basin belongs to the Eastern Region Basins (onshore) and was formerly known as the Bohai Gulf Basin. The Bohai Bay Plains are located in North China (115° to 122° East Longitude and 36° to 42° North Latitude) and have an area of 200,000 km2 . 
The Bohai Bay Basin is characterized by its formation in the Tertiary era as part of the North China Shelf region and includes many depressions (such as Ba Xian, Raoyang, Jin Xian, Qiu Xian, Dongpu, Banqiao, Dongying, etc. ) . . . . The basin contains rocks from the Archean, Proterozoic, Paleozoic, Mesozoic, and Cenozoic periods. This basin was the epicenter of Tertiary earth activity and was controlled primarily by the movement of the Pacific plate. The hydrocarbons present were formed during basin formation and are migrating relatively soon. The subsidence of this valley may be fault depletion or downward deformation. During the Tertiary, the depositional environment in the basin consisted of continental life in fresh to brackish water. Cenozoic units in the Bohai Bay Basin are composed of fluvial marine sediments of gray clastic rocks intercalated between layers of gypsum and halite. The Oligocene era was the main evolutionary period of the Bohai Bay Basin and consists of fluvial lacustrine facies. Neogene strata are composed of riverine swamp areas. The Cenozoic units in the Bohai Bay Basin are divided into: the Paleocene-Eocene Kongdian Formation, the Eocene-Oligocene Shahejie Formation, the Oligocene Dongying Formation, the Miocene Guantao Formation and the Minhuazhen Formation of Pliocene age[14-15]. Sandstone classifications depend on the mineral composition of quartz, feldspar, and rock particles. Most of the samples are in the feldspathic and subfeldspathic arenite sandstone field and a small number are in the lithic arenite arenite field . 
Among the feldspathic sandstones, rich in quartz, feldspar containing more than 25%, and small rock fragments, have long been identified by the term Arkose, which has a granitic or granodioritic composition indicating that it was derived from a large chamber of crystalline basement. Feldspathic sandstone formations contain less than 25% feldspar, indicative of subarcosal or subfeldspathic sandstone. Detrital grains of perthite, microline, and orthoclase generally indicate a source area where granitic and high-grade gneisses and schists occur. The (K, Na)AlSi3O8 sedimentary sand grains indicate an alkaline volcanic origin, while the detrital albite is mainly derived from various low-grade deposits. Potassium and sodium feldspars are the most abundant because they are stable, widespread, and abundant in terranes of continental origin. Limestone sandstones are those with high quartz content, more than 25% rock grains, and small amounts of feldspar. Sublithic sandstone contains less than 25% rock grains. Stone grains may be indicative of the parent rock types from which the sand grains were derived, such as small fragments of volcanic rock from a volcanic source, chert grains derived from a sedimentary source, and mica such as, they may be of fire origin or metamorphic origin. Feldspathic sandstones, found throughout the geological column, have apparent origin significance; the feldspar-bearing source zone is characterized by K-feldspar-dominated granites, gneisses, and other high-grade metamorphic rocks. The feldspathic sandstone in the study area is characterized by: High quartz content, More than 25% feldspar content, Small rock fragments in the its matrix being siltstone, shale, flint and volcanic fragments. The morphology of the feldspathic sandstones is mostly symmetrical with rounded and angular grains. All grains are cemented with a matrix that usually consists of carbonate and silt or clay. subfeldspathic arenite sandstone contains less feldspar than feldspathic arenite. Feldspar is mainly plagioclase feldspar with minor amounts of K-feldspar. Quartz is characterized by angular to rounded grains. Rocky arenite sandstones are characterized by: high amounts of quartz, more than 25% rock grains and small amounts of feldspar. Sandstone rock fragments in the study area are characterized by: abundance of rock fragments, especially of sedimentary origin, and small volcanic fragments.

Carbonate cemented sandstone is normally the most abundant diagenetic mineral available at cheap price per meter, square foot… and is distributed in siliciclastic deposits (Anjos et al., 2000; Ding et al., 2014; Dutton, 2008; Dutton et al., 2002). The quality of siliciclastic oil reserves is greatly influenced by the quantity and distribution characteristics of carbonate cements (Carvalho et al., 1995; Dutton, 2008; Nyman et al., 2014). In addition, carbonate-cement beds will likely form barriers to water flow (Anjos et al., 2000; Dutton et al., 2002; Sun, 1999) and increase reservoir heterogeneity, especially in long-term sandstone deposits. (Dutton, 2008). Therefore, understanding the origin of carbonate cements and identifying their distribution is crucial for reservoir estimation and oil production (Carvalho et al., 1995; Dutton, 2008). The Eocene Es4s interval in the North Dongying Depression, Bohai Bay basin in eastern China (Figure 1) became a rift basin and is an important oil reservoir (Guo et al., 2010). It consists of groups of coarse-grained sublacustrine fan conglomerates, stony sandstones, sandstones, and marine shales (Guo et al., 2010; Wang et al., 2010). Mature source rocks with 0.35 to 1.0% Ro are present during the Es4s (Song et al., 2009). Carbonaceous cements during Es4s are the most viscous and have a significant influence on reservoir quality. 
With a wide range of burial depths (2,500–4,000 m), the widespread occurrence of carbonate cements, the Eocene Es4s area in the north of the Dongying Basin is very suitable for investigating the origin of carbonate cements and their implications at the deposit level. Therefore, the objectives of this section are to (1) document the impact of carbonate cements, (2) identify the source and distribution of carbonate cements, and (3) assess the effect of carbonate cements on quality. of the oil depot.
