摘要： A lost circulation material is placed in a cavity. The cavity is defined by an inner bore of a cylindrical wall, intermediate of a piston and a screen. A distance between the piston and the screen is defined as the height of the cavity, which is adjustable. The piston is slid longitudinally, such that the piston comes in contact with the lost circulation material. The lost circulation material is heated to a specified test temperature mimicking a downhole temperature. A compression test is performed on the lost circulation material. The compression test includes flowing a test fluid into the cavity and applying force on the piston to pressurize the test fluid to a specified test pressure mimicking a downhole pressure. The force on the piston is released. The pressure of the test fluid and the height of the cavity are measured throughout the compression test.

摘要： Sized-bridging agents, wellbore fluid compositions including the agents, and methods utilizing said compositions control, reduce, or prevent fluid losses in wellbores and/or formation damages. One or more divalent organic salts disclosed herein are designed to help mitigate fluid loss by temporarily reducing the permeability of the formation around the wellbore. The sized-bridging agents include sized-divalent organic salts for forming one or more filter cakes to seal one or more portions of the wellbores thereby reducing rates of fluid loss and damages to formations.

摘要： The invention includes methods for stimulating a hydrocarbon-bearing formation by perforating a wellbore and introducing an acidic composition in the wellbore. A preferred embodiment includes inserting an isolation plug in the wellbore at a predetermined location followed by inserting a perforating tool and a breakdown acid into the wellbore. The wellbore is perforated by the tool to create a perforated area. The breakdown acid is allowed to come into contact with the perforated area for a predetermined period of time sufficient to prepare the formation for stimulation. The tool is then removed from the wellbore wherein stimulation of the perforated area is thereby initiated. Also disclosed is a corrosion inhibiting composition for use with the acidic composition.

摘要： A tubular defines a central flow passage. A camera has an aperture and attached to an outer surface of the tubular with the aperture oriented away from the outer surface of the tubular. A lost circulation media reservoir is circumferentially surrounding at least a portion of the outer surface of the tubular. The lost circulation media reservoir is adjacent to the camera. The lost circulation media reservoir includes actuable gates along a periphery of the lost circulation media reservoir. A trigger is communicably coupled with the actuable gates and configured to actuate the actuable gates.

摘要： A device for processing oil or gas well waste solids, the device including a pressurizing discharge unit having a casing. The casing includes a solids inlet and a water inlet. The solids inlet receives treated solids into a front end of the casing, where the treated solids are exposed to a reduced pressure in an internal chamber of the casing of less than atmospheric pressure. The water inlet receives water and adds the water to the treated solids in the internal chamber. The casing includes an extruder screw unit, the extruder screw unit having progressive screw sections located inside the internal chamber and corresponding to conveying mixing and pressurizing screw sections. The conveying screw section conveys the treated solids along a long axis length of the extruder screw unit from the solids inlet towards a discharge end of the casing while the reduced pressure is maintained, the mixing screw section mixes the treated solids and the water together to form a paste, and the pressurizing screw section conveys the paste towards the discharge end and generates, in a portion of the casing downstream from the mixing screw section, a backpressure that is greater than atmospheric pressure. The casing includes a die assembly to extrude the paste through an orifice of the die assembly located at the discharge end while maintaining the backpressure on the paste in the internal chamber. Method and system embodiments for processing oil or gas well waste solids are also disclosed.

摘要： A drilling system for use in drilling a wellbore including a driving mechanism and a separation device disposed upstream of the driving mechanism. The separation device filters at least a portion of any solids from drilling media flowing through a filter flow path of the separation device. The separation device flushes at least a portion of the filtered solids through a flush flow path, through a flush outlet on an outer surface of the separation device, and into an annulus between the outer surface of the separation device and the wellbore. Optionally, the drilling system includes a second driving mechanism and a second separation device disposed above the second driving mechanism.

摘要： Invert emulsions can be used in oil and gas operations. A fluid loss control additive (FLCA) is a component of the fluid that can be utilized to control or minimize fluid loss into a subterranean formation. The FLCA can be a chemically modified vegetable oil that is biodegradable. Vegetable oils having some or all of the functional groups sulfonated can be used as FLCA. A water-soluble salt that has been dissolved in the discontinuous phase of the invert emulsion can combine with the FLCA to form a wax-like, solid mass.
