Patent number: 9376874Abstract: An ejector or jet pump is provided for use in the drilling of wells to prevent the total fluid pressure at the bottom of the borehole from reaching a level which constitutes a risk of cracking the rock or sediment being drilled, thus resulting in leakage and circulation failure. The pump is placed between the drill bit and the drill string and provided with nozzles directed in such a way that low pressure is established externally at the drill bit. The pump is operated by the drilling fluid which is supplied in the normal way through the drill string. The pressure difference across the pump is used to draw a secondary flow of drilling fluid from the borehole through internal bores in the pump to the nozzles in the drill bit. This fluid flow provides necessary cleaning of the drill bit and drilling surface.Type: GrantFiled: July 25, 2011Date of Patent: June 28, 2016Assignee: Tomas ASInventor: Nils Reimers

Publication number: 20130206482Abstract: An ejector pump or jet pump is for use in the drilling of wells in the underground for the production of oil and gas, for example, in which it is the purpose to prevent the total fluid pressure at the bottom of the borehole from reaching a level which constitutes a risk of cracking the rock or sediment being drilled, thus resulting in leakage and circulation failure. For this purpose, the pump is placed between the drill bit and the drill string by means of standard pipe couplings and formed as an elongated cylindrical element with external, longitudinal pump elements with nozzles directed in such a way that low pressure is established externally at the drill bit. The pump is operated by the drilling fluid which is supplied in the normal way from the drill string. The pressure difference across the pump is used to draw a secondary flow of drilling fluid from the established borehole through internal bores in the pump casing to the ordinary nozzles in the drill bit.Type: ApplicationFiled: July 25, 2011Publication date: August 15, 2013Applicant: Tomax ASInventor: Nils Reimers

Publication number: 20120228029Abstract: A method for reducing friction between interconnected outer and inner helical members of a downhole damper where the damper includes an outer damper body and an inner damper body, and where the outer and inner damper bodies are telescopically movable relative each other, the outer and inner damper bodies being biased in the extending direction, and where one of the outer and inner damper bodies are connected to a drill bit workable at a borehole face, and where the other of the outer and inner damper bodies is connected to a torque and force transmitting member, and where the outer and inner helical parts are arranged so as to retract the bit from the face when torque applied by the torque and force transmitting member exceeds a preset value, wherein the method includes letting a relative movement between the inner and outer body force lubricant to flow between the helical members.Type: ApplicationFiled: March 10, 2011Publication date: September 13, 2012Applicant: Tomax ASInventor: Nils Reimers

Patent number: 7712406Abstract: A method is described for detonation of a blasting charge in a fluid environment and which is placed inside a hollow body, such as in an ignition pellet. The method is characterised in that an ignition pellet is used, which is arranged to be deformed under the influence of a number of alterations or pulsations between high and low pressure in the surrounding fluid environment, with the detonation triggering unit inside the body being activated at the subsequent contact with the fluid environment as a consequence of the pellet being deformed. In rupturing, external fluid at overpressure is released into the cylinder and drives a firing pin against a detonating cartridge. A device for an ignition pellet is also described.Type: GrantFiled: November 20, 2003Date of Patent: May 11, 2010Assignee: Total Catcher Offshore ASInventor: Nils Reimers

Patent number: 7654344Abstract: A torque converter for use in drilling with a rotating drill bit, the purpose of the torque converter being to absorb impacts and bring about an axial movement of the drill bit when the torque exceeds a predetermined value. For this purpose the torque converter is composed of two cylindrical string parts connected through the bearing elements. The string parts are connected to each other through helical elements in such a way that relative rotation of the two cylindrical string parts brings about axial movement, which unloads the drill bit.Type: GrantFiled: January 16, 2006Date of Patent: February 2, 2010Assignee: Tomax ASInventors: Per Olav Haughom, Nils Reimers
