Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3852794-MS
... system (BPS) wells and secular variations in concentrations have been poorly understood by oil producers trying to minimize H2S in their wells. The goal of this work was to provide insight into one of the potential mechanisms that caused H2S generation in the BPS. This insight will enable more effective...

... faults are present in the overlying Lamar Formation. In Formation A, MSR is the key generative mechanism of high H2S in the produced gas. During early diagenesis, sulfate-bearing water percolated from overlying anhydrite into the reservoir and sulfate was reduced microbially by using organic matter...

This work first leveraged transient simulations (OLGA) to probe the mechanism of shut-in induced liquid loading in unconventional wells with long laterals. Based on the acquired insights, various machine learning models, including...

... imbibition is the main mechanism by which fracture fluid enters the rock. Herein we study the spontaneous imbibition of brine to determine the flow mechanism and uptake capability of fracturing fluid in unconventional source rocks. We used NMR spectroscopy and imaging methods to track the spatial...

... that the probability of coincidence of conditions favorable for excessive deformation is small. It seems that the plausible mechanism of excessive casing deformation is caused by coincidence of: 1) relatively large increase in the axial force (e.g., due to presence of poor-quality rock along the wellbore), 2) some...

In addition, NFs could be reactivated through shearing, dilation, and extension during hydraulic fracturing. In this study, detailed mechanistic models are employed to examine the effects of these physical...

This is not always an easy task, however, as properly executed, mechanically isolated refracs within a reasonable offsetting distance are sometimes scarce. To enable economic evaluations in such situations, Barba and Villarreal (URTEC...
