Paper Number: URTEC-4031556-MS
... pressure. The results show that after one cycle of hydrocarbon gas HnP, approximately 57% of the original oil-in-place is recovered. We observe that solution-gas drive and gas vaporization during the depletion stage are the main oil-recovery mechanisms. The presence of fractures along the depositional...

... sequential steps to finally have an estimate of cluster efficiency for each hydraulic fracturing stage. First, raw stimulation data acquired from field operations is filtered out to capture a representative zone of interest. Second, key input parameters such as the instantaneous shut-in pressure (ISIP...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 17–19, 2024
Paper Number: URTEC-4028108-MS
... Abstract Efficient optimization of unconventional field development necessitates understanding and prediction of the hydraulic fracturing process. Conventional models fall short in capturing dynamic fluid and rock behavior, hindering the optimization of completion designs. Analytical models...

Paper Number: URTEC-4033730-MS
... medium consisted of two types that are simple trapping mechanism designs (converging-diverging channel and pore doublet) and sample rock-like designs (sandstone and fractured sandstone). The experimental results confirmed that ferrofluid is an effective enhanced oil recovery agent for both the wetting...

... reservoirs characterized by complex, non-uniform fractures, and multi-phase fluid dynamics. These complexities deviate from the diagnostic behavior seen in planar fractures and single-phase flow. To predict well performance under varying pressures and operational conditions, the Hybrid SNR model combines...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 17–19, 2024
Paper Number: URTEC-4029236-MS
... Abstract Unconventional reservoirs typically decline rapidly, with wells producing 40-50% less in their second year of production, compared to their first. Therefore, it is critical to take measures to ensure maximizing the first year's production. Hydraulic fractures should propagate...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 17–19, 2024
Paper Number: URTEC-4026302-MS
... Abstract Butterfly modeling is a technique used in Fractional Dimension Rate Transient Analysis (FD-RTA) that reduces a system with multiple fractures to an equivalent system with a single fracture. With this approach, numerical simulations run in seconds, enabling the automatic calibration...

Paper Number: URTEC-4019465-MS
... Abstract Hydraulic stimulation design requires careful consideration of fracture height and the potential parent-child well interference. To unravel the key factors influencing the vertical growth of hydraulic fractures and parent-child well interference during hydraulic stimulation, we...

... temperature and pressure, deep shales demonstrate compressive strength up to 478 MPa, with peak strain exceeding 1.5%, indicating hindered fracture initiation and expansion. (d) Compared with siliceous shale, carbonate-bearing siliceous shale and argillaceous siliceous shale are easier to crack under high...

Paper Number: URTEC-4042580-MS
... Abstract Shale and tight formations are characterized by extraordinarily low permeability (micro- to nano-Darcy) and existence of natural fractures at various scales. Horizontal drilling with multi-stage hydraulic fracturing has enabled commercial oil and gas production from those...

... a reduction of permeability with distance from the well. FD-RTA creates a variation of area perpendicular to flow with distance from fractures by using variable fracture spacing in a well model. Production and pressure data are used to create diagnostic plots that represent the response of a well to constant...
