Patent number: 11572260Abstract: A method for limiting the speed of a hoist mounted to a mobile well service rig involves determining a safe speed limit that ensures the hoist's capable stopping time is less than the maximum allowed time for stopping. In some examples, the maximum allowed time for stopping is based on the wellstring's modulus of elasticity and independent of the hoist's braking characteristics. The capable stopping time, however, is independent of the wellstring's modulus of elasticity and dependent on the hoist's braking characteristics.Type: GrantFiled: May 3, 2022Date of Patent: February 7, 2023Inventor: Frederic M Newman

Patent number: 11448050Abstract: A mobile service rig includes an onboard rechargeable electric power storage system (e.g., a battery, supercapacitor, etc.) for powering the rig's hoist and other equipment used for repairing or servicing a well at a wellsite. In some examples, the rechargeable electric power storage system is recharged by an electrical power grid that is normally used for powering a pumping unit at the well. Some examples of the mobile service rig include a diesel powered charging generator for backup power. In some examples, an auxiliary braking generator coupled to the rig's hoist provides regenerative braking to help recharge the electric power storage system. Some examples of the mobile service rig comprise a trailer hitched to a diesel powered tractor.Type: GrantFiled: April 25, 2022Date of Patent: September 20, 2022Inventor: Frederic M Newman

Patent number: 11448014Abstract: A mobile service rig includes an onboard rechargeable electric power storage system (e.g., a battery, supercapacitor, etc.) for powering the rig's hoist and drive wheels. Under battery power, the rig travels overland to service wellbores at various wellsites. Once at a wellsite, a pumpjack at the site is de-energized, and the hoist proceeds to remove and reinstall wellstrings (e.g., tubing and sucker rods). While the pumpjack is de-energized, the rig's onboard rechargeable electric power storage system taps into the electric power source normally used for the pumpjack. The drive wheels and hoist can drain the rig's rechargeable electric power storage system, but the pumpjack's electric power source can gradually recharge it while the rig is servicing the wellbore.Type: GrantFiled: April 5, 2022Date of Patent: September 20, 2022Inventor: Frederic M Newman

Patent number: 11401797Abstract: A mobile service rig includes an onboard rechargeable electric power storage system (e.g., a battery, supercapacitor, etc.) for powering the rig's hoist and drive wheels. Under battery power, the rig travels overland to service wellbores at various wellsites. Once at a wellsite, a submerged pump assembly at the site is de-energized, and the hoist proceeds to remove and reinstall tubing and the pump assembly. While the electric pump assembly is de-energized, the rig's onboard rechargeable electric power storage system taps into the electric power source normally used for the electric pump assembly. The electric power source of the electric pump assembly recharges the rechargeable electric power storage system while the rig is servicing the well. When the hoist lowers the tubing back down into the wellbore, the energy generated by that operation is recovered and used for replenishing the rig's rechargeable electric power storage system.Type: GrantFiled: March 18, 2022Date of Patent: August 2, 2022Inventor: Frederic M Newman

Patent number: 9587449Abstract: Example workover vehicles for removing and installing sucker rods and tubing of completed wells include a mast having a distinctive spatial relationship with various equipment of the vehicle. The mast has a series of vertical corner posts or weight bearing derrick legs that define the mast's horizontal footprint. In some examples, a tubing storage rack is situated mostly within the footprint while a rod storage rack is mostly beyond the footprint. A robot traveling vertically along the mast transfers rods and tubing between the well and the appropriate storage rack. In some examples, the rod storage rack pivots between an extended operative position and a retracted transport position. In some examples, a robotic jib transfers rods or tubing to and from a lay-down storage area. Some example robot jibs are movable to a fully deployed position for normal operation and a stored position within the mast's footprint for vehicle transport.Type: GrantFiled: June 13, 2013Date of Patent: March 7, 2017Inventors: Jonathan V.

Patent number: 9524484Abstract: A method for handling water and oil automatically monitors and schedules the trucking of waste water between a disposal site and multiple well sites. In some examples, the method automatically detects the presence of a tanker truck at a well site and/or at the disposal site and records the truck's arrival and departure times. In some examples, the method monitors the changing level of waste fluid collected in a waste fluid storage tank at the well site and thereby determines the volume of waste fluid transferred from the tank to the truck. In some examples, the method also estimates the volume of waste fluid transferred from the well bore into the tank while the truck is withdrawing fluid from the tank. In some examples, the method automatically generates and posts online billing information and regulatory reports associated with waste water trucking, waste water disposal and oil reclaiming.Type: GrantFiled: March 13, 2014Date of Patent: December 20, 2016Inventors: Frederic M. Newman, James B. Story, Meredith K. Peeler, Jesse J. Lee, Steven K. Stout, Kevin A. Vaughn, II

Publication number: 20160160582Abstract: Example well servicing vehicles for removing and installing well strings (e.g., sucker rods and tubing) within wellbores provides a method for determining and logging snag points within the wellbore. In some examples, snag points are determined based on a predetermined change in cable tension, crown load strain and/or hydraulic pressure. The predetermined change is adjusted based on the current length of the well string at the time the snag occurs.Type: ApplicationFiled: February 17, 2016Publication date: June 9, 2016Inventors: Jonathan V.

Patent number: 9115550Abstract: An example robotic method for disassembling and removing a well string (e.g., a string of sucker rods or tubing within a wellbore) involves a computer controlled track and trolley system. Movement of multiple trolleys, carriages, shuttles, articulated arms and other hardware is orchestrated in a manner that minimizes cycle time and thus reduces the overall time for removing the entire well string. In some examples, upper and lower robots travel along and share a first set of tracks while an upper trolley mechanism and a main trolley travel along and share a second set of tracks. In some examples, the two sets of tracks are mounted vertically to a mast, wherein the mast is part of a workover vehicle.Type: GrantFiled: July 24, 2012Date of Patent: August 25, 2015Inventors: Kasia L. Robnett, Frederic M. Newman, Jonathan V. Huseman, Victor D. Trotter, James B. Story

Patent number: 8875365Abstract: A tongs system and method for making and breaking threaded joints of a string of tubing for an oil well involves, in some examples, the use of a set of tongs with a two-speed transmission and a hydraulic system selectively operable in a high-pressure mode and a low-pressure mode. During an initial tightening period, the tongs system operates in high-gear and high-pressure for maximum speed. During a subsequent final tightening period, the tongs system operates in low-gear and low-pressure to controllably tighten the joint to a predetermined target torque. In some examples, to allow the transmission to shift speed without jamming gears, the tongs system pauses for an instant between the initial and final tightening periods. In some examples, the tongs system is interlocked with a hoist and/or other tube-holding and handling equipment.Type: GrantFiled: April 20, 2012Date of Patent: November 4, 2014Inventors: Jonathan V. Huseman, Kasia L. Robnett, Frederic M. Newman

Publication number: 20140290938Abstract: Just above an oil wellbore, an example circumferential displacement tool grips a threaded coupling in performing a circumferential displacement method of properly tightening the coupling to an upper sucker rod and/or to a lower one. In some examples, upper and lower joints of the coupling are tightened sequentially and independently to ensure proper circumferential displacement at each joint. In some examples, during disassembly of a string of rods being withdrawn from the wellbore, the tool can unscrew the coupling selectively from either the upper rod or the lower one. In some examples, a controller monitors the tightening or unscrewing of a joint and derives a joint signature based on a series of torque and rotation readings sampled during the make or break operations. The controller, in some examples, identifies a defective joint by comparing the joint signature to a predetermined reference.Type: ApplicationFiled: March 26, 2014Publication date: October 2, 2014Inventors: Frederic M. Newman, James B. Story, Michael C. Story, Jonathan V. Huseman, Kasia L. Robnett, Victor D. Trotter

Publication number: 20130032358Abstract: The present invention is directed to methods for controlling the operations of a well service rig at a well site by evaluating load sensor data obtained from sensors on or associated with the well service rig. A rig load data chart can be reviewed and an average rig load can be determined for each pull of tubing or rods from a well. The average rig load can be used to calculate and set a rig overload level. If the rig load sensor reads a rig load at or above the rig overload level, the clutch for the hoist can be disengaged and the brake applied to prevent the load from either damaging the rig or breaking off the tubing or rods in the well. In addition, the rig load can be evaluated to determine when the limit the block speed when pulling rods or tubing.Type: ApplicationFiled: July 30, 2012Publication date: February 7, 2013Inventor: Frederic M.
