Patent number: 11959348Abstract: A cable head line cutter tool comprising an internal mandrel anchored to a line and releasably held in an initial position by a locking mechanism disposed within an outer housing of the cable head cutter tool. When a tensile load is applied to the line sufficient to overcome a mechanical resistance acting upon the locking mechanism, and maintained for a duration sufficient to overcome a hydraulic resistance acting upon the locking mechanism, the internal mandrel may become released from the locking mechanism and allowed to travel within the outer housing free of the locking mechanism. In embodiments, the cable head line cutter tool may comprise one or more such locking mechanisms acting independently or in coordination. If the tensile load applied to the line is sufficient to release the mandrel from each of the one or more locking mechanisms and maintained for sufficient duration, the mandrel may cause a line cutter device disposed within the cable head line cutter tool to cut the line.Type: GrantFiled: February 28, 2023Date of Patent: April 16, 2024Assignee: Timesaver Downhole Products, LLCInventors: Robert W. Evans, Chet Brame, Homero Castillo

Publication number: 20230212921Abstract: A cable head line cutter tool comprising an internal mandrel anchored to a line and releasably held in an initial position by a pressure relief valve which may act in coordination with a locking mechanism disposed within an outer housing of the cable head cutter tool. When a tensile load is applied to the line sufficient to overcome an opening pressure of the pressure relief valve and a mechanical resistance acting upon the locking mechanism, and maintained for a duration sufficient to overcome a hydraulic resistance acting upon the locking mechanism, the internal mandrel may become released to travel within the outer housing. If the tensile load applied to the line is sufficient to open the pressure relief valve, release the mandrel from the locking mechanism, and maintained for sufficient duration, the mandrel may cause a line cutter device of the cable head line cutter tool to cut the line.Type: ApplicationFiled: January 3, 2022Publication date: July 6, 2023Applicant: TimeSaver Downhole Products, LLCInventors: Robert W.

Patent number: 11035229Abstract: A system and method for logging in a wellbore where sensor assemblies on a logging tool are deployed and landed in the wellbore. After the sensor assemblies are landed in the wellbore and released from the logging tool, the logging tool is pulled uphole. Moving the logging tool uphole from where the sensor assemblies are landed, reduces interference of the logging tool with measurements obtained with the sensor assemblies. The sensor assemblies include sensors for detecting fluid flow, pressure, temperature, fluid density, formation resistivity, and which can be mechanical, optical, acoustic, or electromagnetic.Type: GrantFiled: March 23, 2020Date of Patent: June 15, 2021Assignee: Baker Hughes IncorporatedInventor: Homero Castillo

Patent number: 8162080Abstract: In an aspect, an apparatus may include a chamber configured to receive a core at a receiving end of the chamber and a cutting device configured to cut the core at a location distal from the receiving end of the core chamber. In aspects, a method may include drilling into the formation to retrieve a core, receiving the core into a chamber at an open end of a chamber, and cutting the core uphole of the open end of the chamber so as to continue to receive the core into the chamber as the drilling continues.Type: GrantFiled: September 23, 2008Date of Patent: April 24, 2012Assignee: Baker Hughes IncorporatedInventor: Homero Castillo

Patent number: 7432716Abstract: A logging tool used in a borehole having non-conductive mud. The tool includes a known inductance in series with an electrode. The quality factor of a circuit that includes the electrode, the inductance and the earth formation is indicative of the resistivity of the formation. The quality factor may be determined using either a plurality of signals or by measuring a transient response.Type: GrantFiled: November 20, 2006Date of Patent: October 7, 2008Assignee: Baker Hughes IncorporatedInventors: Stanislav W.

Publication number: 20070070811Abstract: A circumferential borehole logging system having a rotating head, wherein the rotating head is provided with more than one transducer. The transducers can be disposed at equidistant apart, or at some other angular value. The number of transducers can range from two up. The logging speed of the system is increased due to the additional transducer coverage. Multiple image data sets can be acquired in a single logging pass when different transducer types are used.Type: ApplicationFiled: August 23, 2005Publication date: March 29, 2007Inventor: Homero Castillo
