The present invention relates to the vertical seismic profiling (VSP) of geological formations in which profiling is used to obtain information for performing precise interpretations of geophysical seismic data and better understanding of geophysical information. The disclosure involves using a sound source for generating primary and secondary seismic pulses within well boreholes. The seismic profiling system obtains information regarding a geological formation traversed by a borehole with controllable downhole seismic pulse generators with drill string tool(s). The tool(s) have contact with and are coupled to the formation. A seismic pulsing device (SPD) is attached to a portion of the drill string and a valve controller is used to control opening and closing the valve causing high amplitude short duration ultra wide band pressure pulses, generating primary seismic waves sent into surrounding geological formations. This generates secondary seismic waves received that can be detected by geophones or similar devices.

Borehole flow modulator and inverted seismic source generating system

A hydroelectric control valve (HCV) for a fluid pipeline including an inlet and outlet section attached to a pipeline wherein fluid flows into and out of the HCV that comprises a bell section and a seat reservoir section which are both capped, where the bell section and the seat reservoir section are aligned with each other and are also perpendicular to fluid flowing through the pipeline. An electrical poppet channel is attached to the bell section, such that the bell section includes a bell relief channel in fluid communication with an outlet section and also a separate hydroelectric poppet channel in communication with a locating needle head as well as including a turbine and turbine channel where the turbine channel connects the input section and the seat reservoir and where the seat reservoir section includes a seat reservoir relief channel also in fluid communication with the output section.

Hydroelectric control valve for remote locations

Herein described is a hydroelectric control valve (HCV) for a fluid pipeline including an inlet and outlet (or input and output) section attached to the same pipeline wherein fluid flows into and out of the HCV comprising a bell reservoir section and a seat reservoir section which are both capped, where the bell reservoir section and the seat reservoir section are aligned with each other and are also perpendicular to fluid flowing through the pipeline. A channel which can be electrically activated and thus controlled is attached to a bell section, such that a bell reservoir section includes a bell relief channel in fluid communication with an outlet section and also a separate hydraulic poppet channel in communication with a locating needle head. In addition, turbine and deactivation channels are employed such that the deactivation channel connects the input section and the seat reservoir.

Disclosed is an apparatus, method and system comprising one or more devices capable of modulating fluid flow, the fluid being a liquid or a gas resulting in a pressure fluctuation in a fluid flowing within a flow channel, comprising: a flow modulating device that acts as a servo valve such that the device comprises a shaft and a moveable actuator that slides along the shaft, wherein the shaft and the actuator are positioned at any angle within a principal fluid flow channel such that the fluid flows through the principal fluid flow channel. The fluid flowing within the principal fluid flow channel is selectively reversible and the fluid is connected to both an inner pilot flow channel and the principal fluid flow channel wherein the flow modulating device includes a particulate barrier system having at least one seal system comprising an upper outer seal and a lower outer seal prohibiting fluid particulates from entering the inner pilot flow channel and also includes an upper inner seal and a lower inner seal that further prohibit residual particulates from reaching any mating surface between the shaft of the flow modulating device and the upper seal, the upper inner seal, the lower outer seal, and the lower inner seal. The particulate barrier system operates in a fluid flow field wherein the fluid can flow in any direction and utilizes a sealing system wherein an upper outer seal and a lower outer seal prohibit particulates from reaching the respective surfaces of an upper inner seal and lower inner seal of the flow modulating device. An upper inner seal and lower inner seal further prohibit residual particulates from reaching surfaces between the seal and that of the shaft of the flow modulating device.

High pressure fast response sealing system for flow modulating devices

Disclosed are a system, device, and method for generating pulse signals that correlate to geological information in a wellbore. The system and method comprises a pulse generating device longitudinally and axially positioned within an annular drill collar flow channel such that the drilling fluid flows through the annular drill collar flow channel and the drilling fluid is guided into two sets of selectively reversible flow, upper and lower flow connecting channels, wherein the connecting channels are connected to an inner flow channel and the annular drill collar flow channel, and wherein the annular drill collar flow channel is acted upon by one or more flow throttling devices thereby transmitting signals. The device utilizes a turbine residing near and within proximity of a flow diverter that diverts drilling mud into and away from turbine blades such that the force of the drilling mud causes the turbine blades and the turbine to rotationally spin around a coil assembly.

Measurement while drilling pulser with turbine power generation unit

The system and device described relates to flow pulsing for use in down-hole drilling rate of penetration (ROP) enhancement and measurement while drilling (MWD) using a pulse drilling device (PDD) with a fast acting valve in conjunction with a pilot valve to produce high pressure, high amplitude, low duration pressure pulses.

Pulse rate of penetration enhancement device and method

A device and method and/or system for generating pulses to improve drilling rates, the ability to drill straighter and farther by increasing fracturing or injection efficiencies in a geological formation that may contain desirable hydrocarbons. This system can be used in other types of drilling or fracturing operations, whether to unclog arteries or to open formations for underground storage in conjunction with pulsing/fracturing and create large pulses downhole for seismic purposes. The system and method comprises several pulse generating devices longitudinally and axially positioned within upper, middle, lower, and outer annular drill collar flow channels or packer isolation mechanisms such that the PFD medium flows through the various annular drill collar flow channels and the PFD medium is guided into one or more sets of selectively reversible flow connecting channels, wherein the connecting channels are connected to guide pole channel allowing for controlling pulsing within the geological formation.

Flow hydraulic amplification for a pulsing, fracturing, and drilling (PFD) device

A device, method, and system for creating a pressure pulse from drilling fluid within a drill string in a down hole drill collar for enabling measurement-while drilling. The device and system are designed such that primarily laminar flow exists in the area surrounding the pulser apparatus. The method associated with the reproducible and essentially noise-free pulses occurs when a pulser bell is manipulated in an upward and downward direction by a combination of the solenoid activation of a bi-directional poppet to redirect the fluid flow from the pressure reservoir to and from a sliding pressure chamber and associated upper and lower flow connecting channels. The pulse or non-pulse is converted into a digital signal uphole by a pressure transducer in conjunction with a decoding algorithm. It is then displayed to the driller and oilfield operators as useful directional and formation information that help the oilfield operator for uphole decision making regarding directional drilling. Additional pulsers can be added to the tool so that higher data bit rates can be accomplished. These higher data bit rates will provide for more comprehensive data collection thereby reducing drilling costs and optimizing oil field yields. The higher bit rate allows for more sensors that can send additional and improved information uphole without the use of open hole wire line logging which is impossible to accommodate while drilling horizontally.
