Paper presented at the SPE Annual Technical Conference and Exhibition, October 3–5, 2022
Paper Number: SPE-210291-MS
... Abstract Polymer injection has been widely established for mobility and conformance control during enhance oil recovery (EOR). However, its role in resolving the water-channeling problem in carbonate reservoirs becomes challenging due to the existence of heterogeneous and complex fracture...

Paper Number: SPE-210295-MS
.... Porosities range up to 12%, and the main producing interval (MA-72) has an average porosity of 9% and average permeability of 4.5 mD. Production delivery relies on artificial fracturing of the reservoir (Knox, et al., 2008). Abstract CO2 plume geothermal technology (CPG) has been developed in recent...

Paper Number: SPE-210335-MS
... Abstract Over the past several decades, Arps decline curve analysis (DCA) has proved to be effective and efficient for production forecasts and EUR estimates due to its simplicity and applicability. However, as multi-stage hydraulically-fractured horizontal wells have unlocked the economic...

Paper Number: SPE-210359-MS
... Hydraulic fracturing with proppant laden slurry has been used to stimulate well performance in the oil and gas industry for many decades. Some formations, such as soft rock, loosely consolidated or unconsolidated sandstone, are prone to producing both proppant and formation solids after...

Paper Number: SPE-210363-MS
... effective gas porosity and permeability, the low net-to-gross (NTG) ratio requires a larger quantity of proppant to adequately support a fracture that covers the entire thickness of the sand interval. Because of these issues, the reservoir potential is not capable of supporting costly conventional...

Paper presented at the SPE Annual Technical Conference and Exhibition, October 3–5, 2022
Paper Number: SPE-210311-MS
... Gels (PPGs) have been widely applied to control excessive water production in mature oil fields with fractures or fracture-like features, especially in sandstones, but with limited attention to carbonates. However, a vital concern arises regarding the potential damage of PPGs on the adjacent matrix...

Paper Number: SPE-210017-MS
... The Montney rock in our samples is a highly cemented siltstone. It is expected to be very hard and strong with smaller apertures for any induced fractures and higher breakdown pressures. To assess the ability of proppant to be transported in the fractures, polystyrene beads of known size...

Paper Number: SPE-209995-MS
...Introduction Abstract This study discusses the development of a diverting agent (DA) performance prediction model for simultaneous hydraulic fracture propagation based on numerical and machine learning approaches. The filtrate capacity of a particulate DA plug was quantified by the filtrate...

... of the maximum enhancement in fracture gradient of wellbores. An analytical solution is developed for this purpose that accounts for wellbore inclination and azimuth. The LCM blend is selected by applying appropriate criteria for the particle size distribution (PSD) to the estimated width of near-wellbore...

Paper Number: SPE-210098-MS
.... The stabilizing nanoparticle is a dry solid with a particle size of approximately 100-200 nano-meters, deformable, stable, and with a dispersed zeta potential -10 to -20mV. The product can mechanically ‘seal’ micro-fractures and possibly large pore throats in shale thus assisting in forming a semi-permeable...

Paper Number: SPE-210388-MS
... Conventional modeling of coupled flow and geomechanics in fractured reservoirs requires computation meshes conforming to the fracture geometry, which not only needs complicated gridding techniques but consumes a huge amount of computing resources. The objective of this paper is to present a numerical model...

... coefficients has been used in fractured reservoirs. When diffusion is included in the model, the cyclic solvent injection performance becomes more sensitive to soaking time than the model without diffusion. However, nanopore confinement is not considered in MS formulation. Based on ultra-high resolution...

... acceptable results. The hidden assumption behind analysis is assuming uniform closure of fractures at the last step of the tests. Basically, the uniform closure is the only considered form of fracture closure in all the existing analyses for this test. Here, we show how adjusting flowback rates may change...
