Abstract: To separate porosity from surface roughness, length scales for pore size and surface roughness are identified. These length scales are determined from surface roughness measurements and confirmed via NMR pore body calculations and pore size capillary pressure measurements. A filter removes pore contribution to surface roughness measurements and delivers intrinsic surface roughness. Additional filters and methods determine the minimum magnification on which to base surface roughness calculation, based on size of the field of view and where measured surface roughness approaches intrinsic surface roughness as magnification increases but larger magnification increase sampling time and difficulty. Sample irregularities, such as saw marks, are also filtered out or determined to be too large to remove via filter and another area of measurement is located. With the pore corrected quantification of surface roughness, surface relaxivity and pore distribution can be calculated with greater accuracy.

Abstract: System and methods of petrophysical modeling are disclosed. Training data for modeling a reservoir formation surrounding a wellbore drilled within the reservoir formation is received via a network from one or more data sources. A machine learning model is trained using symbolic regression to determine a formation model representing the reservoir formation, based on the training data received from the data source(s). At least one property of the reservoir formation is estimated, based on the formation model. A downhole operation is performed along the wellbore within the reservoir formation, based on the at least one estimated property.

Abstract: Pressure coring where the core apparatus drills the core sample and seals the core sample at its native downhole pressure (e.g., several thousand psi) may be expanded to include nuclear magnetic resonance (NMR) imaging components to produce a pressurized NMR core holder that allows for NMR imaging of the core samples having been maintained in a downhole fluid saturation state. NMR imaging performed may include 1H and also 19F imaging depending on the chamber fluid used in the pressurized NMR core holder.

Abstract: The present disclosure is directed to a method of determining wettability characteristics of a sub-surface formation within a wellbore utilizing nuclear magnetic resonance (NMR) and bulk fluid measurements at various stages of fluid saturation at that wellbore location. In another aspect, the pumping pressure is incrementally changed within the wellbore, measuring injection fluid and hydrocarbon saturation data values between the incremental pump pressure changes. In another aspect, a measuring and sampling tool is disclosed to execute the method and produce wettability characteristics. In another aspect, a system is disclosed that can operate NMR devices, bulk fluid equipment, pump systems, and other devices to collect data and to determine wettability characteristics on the collected data.

Abstract: Methods, devices, and systems for tracking lateral motion of a nuclear magnetic resonance (NMR) tool are disclosed. In some embodiments, a phase shift for one or more spin-echo signals received by the NMR tool is detected during a velocity measurement sequence that corresponds to at least one formation measurement sequence. A lateral velocity of the NMR tool is determined based, at least in part, on the detected phase shift.

Abstract: An NMR logging system is disclosed which continues logging without interruption despite switching activation sets to adapt to changes in formation properties. Based on detection of an approaching or encountered geological boundary, an appropriate activation set is transmitted to the downhole NMR tool while the NMR tool continues logging. This system optimizes NMR data collection for each formation and associated formation fluid properties while reducing the need to stop the tool string movement while switching the activation set, and reduces incomplete collection of NMR and non-NMR logging tool data.

Abstract: A method and system for downhole, real-time determination of relative permeability with nuclear magnetic resonance and formation testing measurements is provided. The method includes introducing a nuclear magnetic (NMR) tool and a formation testing tool into a well bore penetrating a subterranean formation. The method also includes measuring a saturation of a fluid in the subterranean formation from the NMR tool, measuring a mobility of the fluid from the formation testing tool, and measuring a viscosity of the fluid. The method includes calculating a relative permeability of the subterranean formation based on the measured saturation, the measured viscosity and the measured mobility. The method also includes providing a reservoir production prediction metric based on the calculated relative permeability of the subterranean formation for facilitating a well completion operation in the wellbore.
