Title: A braking system and wellbore fluid sealing systems for progressive cavity pump(pcp) drive head
Inventor: YIN MINHAO
IPC: F16D57/06
Filed: 2021-01-25
Abstract: Present invention relates to a braking system and a wellbore fluid sealing system for a progressive Cavity Pump (PCP) drive head. A braking system is for controlling the release of torsional energy in a controlled manner in a rod string between a drive head and a downhole rotary pump. A rotary hollow shaft drives a fluid pump through a clutch so that when the top end of the rod string rotates in the normal operation direction, the clutch is in non-contact position and does not run the fluid pump. However, when the top end of the rod string seeks to rotate in the opposite direction, the fluid pump is operated through the clutch engagement to pump fluid from a reservoir and back to the reservoir via a flow control valve for restricting fluid flow. This process results in controlling the rate of rod string backspin speed. A wellbore fluid sealing system is for sealing wellbore fluid from leaking onto the ground during operation. The wellbore fluid sealing system includes a seal housing assembly, a sealing sleeve. The sealing sleeve is rotatable relative to the seal housing assembly. The sealing sleeve is connected to the rod string via a driving connector. Lip seals which are installed inside Seal housing, rest against the rotating sealing sleeve external hardened surface to seal wellbore fluid. Field quick replaceable seal assembly may be installed through the top annular opening formed between hollow rotating main shaft internal bore and the external cylindrical surface of a polish rod, landed, and locked at a desired position to seal crude oil.

Abstract: A computer-implemented method for determining survey sampling parameters for species marker detection comprises receiving a species selection identifying selected species and receiving environmental specifications for an environment to be tested for the species.  A sampling plan is generated using the environmental specifications and the species selection, and detectability prediction(s) are generated using the environmental specifications, the species selection, and the current sampling plan to predict whether species marker(s) for the selected species are detectable according to the current sampling plan. Where at least one species marker is undetectable according to the current sampling plan, the process iterates, with each subsequent iteration incorporating an increase in the total volume to be sampled, until either every species marker is detectable according to the then-current sampling plan or an iteration stop limit is reached. The sampling plan(s) and detection prediction(s) are generated using different algorithms.

Abstract: Resonant sweeping frequencies are estimated for specific rock types, saturated with various formation fluids at reservoir conditions. A sequence and duration of resonant frequency sweeps and high amplitude low frequency vibration/agitation at each station is designed based on petrophysical and geomechanical properties, and in-situ stress conditions. Resonant sweeping and agitation is conducted as a multiple resonant frequency (fixed or variable) tool passes at optimal speed, which will be determined for specific reservoir type and downhole conditions. Resonant stimulation tool type, or combination of tools, is selected based on borehole size, reservoir parameters and resonant frequency requirements to maximize the efficiency of stimulation. Broad range of operating frequencies will allow to tune to resonant frequencies of various formation types (sandstones, limestones, shales, dolomites, and heterogeneous reservoirs comprised of the mixture of above lithologies). Low frequency transducers increase fluid displacement, and improve ultimate formation fluid recovery.

Abstract: Applicants have discovered an innovative approach to robustly and accurately detect Alzheimer's disease (AD) and prodromal forms of AD based on the distinction of specific atrophic patterns of anatomical structures such as hippocampus (HC) and entorhinal cortex (EC) in regions of interest of an image. The discovery allows to efficiently determine a pathological status and grading of pixels of interest when compared (weighed) to images from a reference library having pre-defined states. The discovery simultaneously performs segmentation and grading of structures to efficiently capture the anatomical alterations caused by AD. Based on a nonlocal patch-based framework, the grading measure estimates the similarity of the patch surrounding the voxel under study with all the patches present in different training populations.
