Patent number: 11598481Abstract: A method for determining when to change a lubricating fluid flowing within an apparatus includes monitoring the lubricating fluid flowing within the apparatus by passing radiation through the lubricating fluid from a radiation source. The lubricating fluid is analyzed for a presence of particles in the lubricating fluid based on the radiation passing through the lubricating fluid. A concentration of the particles in the lubricating fluid is determined when the presence of particles is detected. An alert to change the lubricating fluid is generated when the concentration of particles in the lubricating fluid exceeds a threshold.Type: GrantFiled: September 20, 2016Date of Patent: March 7, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Wolfgang Hartmut Nitsche, John Laureto Maida

Patent number: 11299983Abstract: A method and system are disclosed that provide chemical composition data of a fluid. The system includes a first downhole electro-opto-mechanical device to transmit microwave radiation through the fluid. The microwave radiation is generated by the first downhole electro-opto-mechanical device in response to a first light signal. A second downhole electro-opto-mechanical device receives the microwave radiation and generates a second light signal in response to the received microwave radiation. A light detection device is coupled to the second downhole electro-opto-mechanical device to generate an electrical signal in response to the second light signal. The electrical signal is indicative of the chemical composition of the fluid.Type: GrantFiled: September 29, 2016Date of Patent: April 12, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Satyan Gopal Bhongale, Wolfgang Hartmut Nitsche, Yenny Natali Martinez

Patent number: 11199086Abstract: A method and system can include positioning an optical waveguide along a wellbore, and launching one or more optical signals into the waveguide at one or more optical signal frequencies and during one or more time periods, thereby resulting in one or more backscattered signals being received by the receiver, which produces a trace for each of the one of more backscattered signals. Changing an environmental condition in the wellbore, generating additional backscattered light signals at one or more frequencies after the change. Comparing the traces generated before the condition change to those generated after the change, identifying a before trace and an after trace that are substantially equal to each other and identifying a frequency difference between these traces. The frequency difference can be used to determine the amount of change in the environmental condition that occurred when the environmental change event happened.Type: GrantFiled: September 2, 2016Date of Patent: December 14, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Michel Joseph LeBlanc, Wolfgang Hartmut Nitsche, Jose R.

Patent number: 11028688Abstract: To optimize the efficiency and reliability of downhole data transmissions, an optical splash communication system may be utilized. A downhole tool may include an optical splash communication system that comprises multiple electrical elements where the electrical elements communicate with each other by transmitting and receiving via free space an optical splash signal through an inner space of the downhole tool. The electrical elements may comprise or be coupled to a light source and a detector. Multiple optical splash communication systems may be deployed in multiple downhole tools such that each downhole tool may communicate with another downhole tool via an opening, for example, a transparent sealed window, between the downhole tools. The opening is sufficient to permit transmissions to occur even when the downhole tools are rotated independently of each other.Type: GrantFiled: July 11, 2016Date of Patent: June 8, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Casey Giron, Wolfgang Hartmut Nitsche, John Laureto Maida
