20220127959 | Reservoir Characterization Using Rock Geochemistry for Lithostratigraphic Interpretation of a Subterranean Formation - Methods and systems for reservoir characterization use identification of lithostratigraphic layers within a subterranean formation based on rock geochemistry of the subterranean formation. This approach includes: collecting rock samples related to lithostratigraphy of target wells in the subterranean formation; measuring geochemical/mineralogical parameters of the rock samples with laboratory equipment; measuring geochemical/mineralogical parameters of the subsurface formation using wellbore geochemical logging tools in the target wells; measuring formation acoustic velocities for the target wells; generating characteristic rock sample and log signature patterns for different lithostratigraphic layers based on the measured geochemical/mineralogical parameters and acoustic velocities associated with the different lithostratigraphic layers identified in the target wells; combining the characteristic log signatures for the different lithostratigraphic layers into a lithographic interpretation using neutron capture spectroscopy model; and identifying the lithostratigraphic layers within the subterranean formation by applying the model to well logs of non-target wells. | 2022-04-28 |
20220127960 | METHOD FOR CONSTRUCTING GROUNDWATER MONITORING WELL INSIDE PRB TRENCH - Disclosed is a method for installing a groundwater monitoring well inside a permeable reactive barrier (PRB) trench including excavating a PRB trench, installing a trench side-wall support, positioning a monitoring well borehole, installing an outer installation casing for pre-burying the monitoring well, installing a monitoring well positioning bracket, installing a monitoring well casing, installing monitoring well filter packs and seal materials, filling the trench with PRB media and capping with a covering soil layer, removing the outer installation casing, removing the trench side-wall support, completing the monitoring well with a wellhead, and conducting well development. This method avoids the complex procedure of re-drilling a borehole within the PRB media following the completion of PRB construction and media filling, assures that monitoring well installation protocols are followed and high quality and stable operation is achieved, and serves for groundwater monitoring to support the implementation and efficacy evaluation of the PRB technology. | 2022-04-28 |
20220127961 | METHODS TO CHARACTERIZE WELLBORE FLUID COMPOSITION AND PROVIDE OPTIMAL ADDITIVE DOSING USING MEMS TECHNOLOGY - A method comprising determining a concentration of one or more components of a wellbore servicing fluid during a wellbore servicing operation; and adjusting or maintaining a composition of the wellbore servicing fluid being introduced into a wellbore and/or an operational parameter of the wellbore servicing operation based on the determining of the concentration of the one or more components, wherein the determining of the concentration of the one or more components comprises contacting a sample of the wellbore servicing fluid with a microelectromechanical system (MEMS) device to provide a sample response indicative of the concentration of the one or more components. | 2022-04-28 |
