Paper presented at the APOGCE 2024, October 15–17, 2024
Paper Number: SPE-221156-MS
... Abstract Gulong shale oil is characterized by abundantly enriched nanopores and bedding fractures. A critical challenge of shale oil reservoir simulation is the representation of complex cross-scale flows among tight matrix, bedding fractures and hydraulic fractures, which require fine gridding...

Paper presented at the APOGCE 2024, October 15–17, 2024
Paper Number: SPE-221242-MS
... Abstract The study and assessment of flow conductivity within infilled-shear fractures play a pivotal role in guiding the development of shale gas resources. This paper presents an investigation using shale reservoir rock samples from the Longmaxi Formation. We employed a novel infilled-shear...

Paper presented at the APOGCE 2024, October 15–17, 2024
Paper Number: SPE-221139-MS
... Abstract Lost circulation pose a primary challenge in the exploration and development process. For the problem of Lost circulation in fractured formations, the addition of plugging materials with different functions and in specific proportions into the drilling fluid to seal the fractures...

Paper presented at the SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, October 10–12, 2023
Paper Number: SPE-215203-MS
... Traditional analytical well-testing methods are not applicable to fractured low-porosity sandstone reservoirs. Besides, numerical well-testing describing the transient pressure response of each grid cell at different moments, which makes the interpretation results more accurate and reliable...

Paper Number: SPE-215323-MS
... must be selected in such a way that it maintains the primary pressure barrier for well control while minimizing the fluid loss into the reservoir. Loss of workover fluid is a common and major challenge faced while workover of wells completed in reservoirs with natural fractures and depleted pressures...

Paper presented at the SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, October 10–12, 2023
Paper Number: SPE-215288-MS
... Currently, in numerical simulations of reservoirs, frequently employed mathematical models for describing fractures include the continuum model, dual-porosity model, discrete fracture model (DFM), etc. ( Kazemi et al. (1976) ; Rossen et al (1977 ); Lim & Aziz (1995) ; Quintard...

Paper presented at the SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, October 10–12, 2023
Paper Number: SPE-215402-MS
... Abstract Acid fracturing is an essential technology for the efficient development of oil and gas reservoirs containing carbonate. However, in the case of deep and ultra-deep marine carbonate oil and gas reservoirs, existing acid fracturing technologies are unable to create a complex fracture...

Paper presented at the SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, October 10–12, 2023
Paper Number: SPE-215484-MS
...Physical model Shale matrix consists of organic pores and inorganic pores, and it develops micro-fractures. After hydraulic fracturing, the reservoir forms multi-scale fractures, including laminated fractures and hydraulic fractures. Different-scale media, such as organic matter, inorganic...

Paper presented at the SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, October 10–12, 2023
Paper Number: SPE-215482-MS
... Abstract The use of volume-oriented completion and fracturing practice in Ordos Basin shale oil wells began in the mid-2010s, and it was effective in boosting productivity. However, recently, well performance has stopped improving and the engineering effort has increased, indicating...

Paper presented at the SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, October 10–12, 2023
Paper Number: SPE-215314-MS
... Abstract An advanced numerical simulation method was developed to accurately characterize the heterogeneous geomechanical damage of heterogeneous matrix, hydraulic fractures, and natural fractures during production. The proposed model can automatically obtain the geomechanical damage correction...
