    Abstract: Systems, methods, and devices for determining neutron-gamma density (NGD) measurement of a subterranean formation that is accurate in both liquid- and gas-filled formations are provided. For example, a downhole tool for obtaining such an NGD measurement may include a neutron generator, neutron detector, two gamma-ray detectors, and data processing circuitry. Neutron generator may emit neutrons into a formation, causing a fast neutron cloud to form. Neutron detector may detect a count of neutrons representing the extent of the neutron cloud. Gamma-ray detectors may detect counts of inelastic gamma-rays caused by neutrons that inelastically scatter off the formation. Since the extent of the fast neutron cloud may vary depending on whether the formation is liquid- or gas-filled, data processing circuitry may determine the density of the formation based at least in part on the counts of inelastic gamma-rays normalized to the count of neutrons.

    Abstract: The application discloses a method of treating a subterranean formation of a well bore, including providing a first treatment fluid substantially free of macroscopic particulates; pumping the first treatment fluid into the well bore at different pressure rates to determine the maximum matrix rate and the minimum frac rate; pumping the first treatment fluid above the minimum frac rate to initiate a fracture; providing a second treatment fluid comprising a second carrier fluid, a particulate blend including a first amount of particulates having a first average particle size between about 100 and 2000 µm and a second amount of particulates having a second average particle size between about three and twenty times smaller than the first average particle size, such that a packed volume fraction of the particulate blend exceeds 0.74; pumping the second treatment fluid below the minimum frac rate; and allowing the particulates to migrate into the fracture.

    Abstract: Methods for controlling fluid flow through one or more pathways in one or more rock formations penetrated by a borehole in a subterranean well, comprise injecting into or adjacent to the formation a treatment fluid comprising at least one polysaccharide polymer; at least one crosslinker; and fibers, or a mixture of fibers and particles. The fluids are pumped into the well through a tubular body that comprises at least one flow restriction. Shearing of the treatment fluid as it passes through the flow restriction causes the viscosity to decrease, allowing the fibers to form masses that migrate to formation- rock openings such as pores, cracks, fissures and vugs. As a result, the fibrous masses are useful for curing lost circulation, providing fluid-loss control and as diverting agents.

    Abstract: An assembly and techniques for employing multiple motors to drive an oilfield injector. The injector is configured to drive a well access line such as coiled tubing and the motors may be electric in nature. Additionally, the motors are configured to operate at substantially sufficient cooling speeds for electric motors. Nevertheless, the motors are coupled through a common differential mechanism such that a range of differential speeds may be derived via comparison of the operating speeds of the motors. Thus, a wide array of injection speeds may be employed without requiring the motors to operate at dangerously low speeds in terms of electric motor cooling.
