... in the pore space. In this work, we generalize the ThomasStieber (T-S) concept to develop an inversion-based interpretation method of well logs to estimate storage and flow properties of arbitrarily heterogenous sandstone-shale sedimentary sequences. Firstly, we use well logs to simultaneously estimate shale...

... with strong water influx, a wide density-neutron log separation is observed along parts of the horizontal sections of the production wells. Following the classic interpretation, these sections are regarded as "gas zones," even if quantifying the amount of gas (free or residual) is challenging...

..., USA, June 10-14, 2023. ABSTRACT Participation in over 80 carbon capture and sequestration (CCS) projects spanning 25 years has led to the evolution of a recommended well-based appraisal workflow for CO2 sequestration in saline aquifers. Interpretation methods are expressly adapted for CCS applications...

While laterally extensive fracture networks can increase the depletion area, they can create challenges due to fluid channelingpressure communication. Electrical imaging is used at the wellbore to identify fractures/faults. However, interpreting open...

The ultrasonic imagers with a rotating transducer provide complete wellbore azimuthal coverage as compared to the pad type electrical imagers in which the coverage depends on the hole size and tool design. In this paper the direction of the created fracture was identified with an electrical...
