“…This creates an economic barrier/risk as there is no certainty that a site will be capable of storge prior to drilling. Although for new site exploration initial drilling is necessary to obtain core samples, 3D-printed cores could potentially be used to replicate samples of previous wells as a cost saving measure [51]. It is assumed that best practice for borehole drilling is already conducted due to the years of aquifer use in natural gas storage.…”

“…The melted filament is deposited and solidifies to form the 3D-printing layers, one by one. A laser beam is used in the SLA technology to cure liquid photopolymer resin into solid according to the object geometry . Finally, deposition 3D-printing technology uses a selective silica or gypsum powder and a jetting-binder material to build the object geometry layers.…”

Simplifying fluid-flow physics in conventional reservoirs is convenient by assuming uniform lithology and system-geometry with minimal rock/hydrocarbon interactions. Such simplification restrains mathematical models’ ability to simulate unconventional reservoirs’ actual flow behavior and production performance. Researchers can achieve precise adaption for the physics of fluid flow in porous media if they geometrically characterize the system under study appropriately, and there are minimal interactions indeed. 3D-printed replicas of porous-rock samples obey this criterion. In this work, we used image-processing tools used for creating presentable porous and permeable replicas of different scales and configurations of the petroleum system from lab-scale to field-scale. The workflow of 3D-printed replicas creation is presented for replicas of conventional core samples, naturally and synthetically fractured cores, geological drilling units of multistage fractured horizontal wells, and full-field models, e.g., Norne field in Norway. These samples are ideal for experimentally testing the validity of the analytical or numerical models of oil and gas reservoirs in the laboratory, along with judging the quality of reservoirs’ characterization. These replicas’ ideality of these results from limited uncertainties of the geometry of the system under study and fluid/rock interactions because of the uniform composition. For validation purposes, 3D-printed replicas with different materials and 3D-printing technologies were created based on a reconstructed image-processed CT scan of their original Berea sandstone. These replicas were tested for storage capacity (porosity) and transport capacity (permeability) and compared with their original sample’s capacities. The matched results proved replicas’ ability to be used in oil and gas laboratory experimental research.

“…However, the interest in the mechanical and petrophysical properties of sandstones and carbonates and the behavior of rocks due to rock and fluid interaction leads to demand for rock sampling. It is not always possible to extract a sufficient quantity of samples in the field, due to lack of availability, and the limited samples available are inconvenient for laboratory tests that require a significant number of samples to represent a given problem, especially for geomechanical destructive tests [5][6][7]. Furthermore, due to the complex porous system and its heterogeneities, carbonate reservoirs [8] cause experimental uncertainties, making it difficult to obtain comparable and reproducible results [5,[9][10][11].…”

Carbonate rocks are important for the petroleum industry, as they contribute significantly to hydrocarbon reserves, although their analysis is complex due to the high cost of core sampling and their high heterogeneity; for this, synthetic rocks aim to provide relatively homogeneous samples with analogous characteristics to natural rocks. In this research, synthetic carbonate rocks were produced by mixing a fixed ratio between limestone powder, obtained from limestone mining waste, and epoxy resin as a cementing material, using compaction energy for consolidation. The work aimed to produce homogeneous samples with high strength, reproducing the intergranular pore system for future applications in rock–fluid interaction analysis. The characteristics and structure of the samples were investigated through X-ray computed microtomography, petrographic images, petrophysical, chemical and geomechanical tests. Results showed a direct increasing relationship between porosity and permeability and a tendency for mechanical strength (UCS) to decrease with increasing porosity. When compared with the natural carbonate rocks, these presented similarities in their mechanical properties and petrophysical measurements, showing that the methodology can be considered as an alternative for the obtention of a realistic material that can be used for future experiments regarding rock mechanics and rock–fluid interaction for prediction of carbonate rocks’ behavior.
