Paper presented at the SPE/AAPG/SEG Asia Pacific Unconventional Resources Technology Conference, November 16–18, 2021
Paper Number: URTEC-208402-MS
... after hydraulic fracturing is presented, along with the pilot testing of 15 datasets. The model extends the scope of an industry-leading thermal production logging software with fracture diagnostic functions. During the development process, we identify the main differences in analyzing temperature data...

Paper Number: URTEC-208395-MS
... Abstract Hydraulic fractures created during completion operations are assumed to produce back to the original well. While multi-well pad completions increase efficiencies, it complicates fracture connectivity between wells. The proximity of newly completed wells to a pre-existing producing well...

Paper presented at the SPE/AAPG/SEG Asia Pacific Unconventional Resources Technology Conference, November 16–18, 2021
Paper Number: URTEC-208318-MS
... Abstract In this paper, the width and length of a hydraulic fracture are estimated from the analysis of wave propagation from an active to an offset well. The method is based on a Krauklis wave model, which describes acoustic waves, propagating in a narrow layer, filled with a viscous fluid...

Paper presented at the SPE/AAPG/SEG Asia Pacific Unconventional Resources Technology Conference, November 16–18, 2021
Paper Number: URTEC-208296-MS
... Abstract One of the challenges when performing hydraulic fracturing is treating reservoirs that are close to a water-bearing zone. Unfortunately, uncontrolled fracture height growth adversely affects many treatments and often increases the probability of water influx. This risk of fracture...

Paper presented at the SPE/AAPG/SEG Asia Pacific Unconventional Resources Technology Conference, November 16–18, 2021
Paper Number: URTEC-208276-MS
... Abstract The objective of this paper is to investigate how to acquire fracture closure pressure data accurately and cost-effectively in shale development activities. If the injection volume is small during a hydraulic fracturing job, it is a common practice to consider the ISIP (Instantaneous...

... production. Due to the strong heterogeneity, relatively developed weak planes such as natural fractures and bedding fractures, and the large fracturing fluid leak-off, hydraulic fractures usually propagate non-uniformly and non-continuously and form into complex fractures network, making the pressure curve...

Paper Number: URTEC-208299-MS
... Abstract Proppant transport and distribution within fractures is an important part in hydraulic fracturing. At present, the majority of the experiments and simulations are applied to parallel planar fracture consideration. The transport and distribution of proppant within tortuous fractures...
