    Abstract: Systems and methods for utilizing finite difference stimulation results to compute streamline trajectories are described. One example of a method for calculating a streamline includes: initializing a seed point within a simulation grid cell; computing a velocity vector for the seed point; selecting an incremental distance in a direction of the velocity vector; computing coordinates for a new seed point location based on the incremental distance and the direction of the velocity vector; computing another velocity vector for the seed point; selecting an incremental distance in a direction of the another velocity vector; computing coordinates for another new seed point location based on the incremental distance and the direction of the another velocity vector; computing an incremental time of flight for each incremental distance based on a velocity for each respective velocity vector and the respective incremental distance; mapping a color for each incremental time of flight to each respective incremental distance; computing an accumulated time of flight; adjusting the accumulated time of flight to zero at an end of the streamline nearest an injection well; and displaying each color representing the accumulated time of flight on the streamline between the end of the streamline nearest the injection well and another end of the streamline nearest a production well or a stagnation region.

    Abstract: A well bore (10) having a conduit (12) disposed therein where portions of the well bore and conduit are positioned substantially horizontally in a subterranean producing formation (14), is completed by placing a hardenable resin composition coated particulate solid material in the annulus between the sides of the well bore (10) and the conduit (12) and causing the resin composition to harden whereby the particulate material is consolidated into a hard permeable mass. An aqueous cement slurry (30) is introduced into the permeable consolidated particulate material whereby horizontal sections thereof are isolated which allows tests and/or treatments in selected portions of the horizontal well to be performed.

    Abstract: A well bore measurement tool for a well bore having a side wall, comprises: lower packer (6) for providing a lower seal in the well bore; upper packer (8) for providing an upper seal in the well bore; caliper means (10) for measuring a deflection of the side wall (4) of the well bore; and retainer means (9) for retaining the caliper means between said lower and upper packer means so that the caliper means is transportable into the well bore with said lower and upper packer means but so that said lower and upper packer means are longitudinally movable relative to the caliper means when said caliper means engages the side wall of the well bore. The caliper is preferably mounted on two springs in a free-floating manner between the upper and lower packers, and has radially extendible arms which are extendible in response to independent forces exerted thereon, as preferably derived from the movement of a carriage driven by a single motor contained in the caliper tool. A clutch mechanism is used to lock the arms to precision measurement transducers only after the arms have been moved radially outwardly a sufficient distance.

    Abstract: A packer perforate, test and sample tool includes a tester valve (10) which is positioned above a well packer (28) and which has a bypass which provides communication between a well annulus above the packer and a firing mechanism (36) for guns (34) positioned below the packer. When the well annulus pressure is raised, the firing mechanism is triggered. The bypass may be closed prior to firing of the guns, and after perforation, a valve in the tester valve may be opened to flow a sample of well fluid into a sampling chamber (20) located above the tester valve.

    Abstract: Stable oil external-aqueous internal emulsions are used to treat subterranean formations by acidizing or diverting, for example, the method comprising: (a) mixing a particulate silica compound having a particle size in the range of 5 to 500 microns and having at least 16% of the total particles of a size less than 20 microns, with an aqueous liquid to form an aqueous slurry; (b) mixing oil with a surface active agent which promotes the formation of an oil external-aqueous internal emulsion; (c) combining the aqueous slurry and the oil-surface active agent mixture to form an oil external-aqueous internal emulsion; and (d) introducing the oil external-aqueous internal emulsion into the formation by way of said well bore. a

    Abstract: Assembly for reducing the force applied to a guide lug (148) received in a slot. An outer telescoping member (18) includes a guide lug (148) extending from the radially inner surface thereof which is received in a groove formed on the radially outer surface of an inner tubular member (58) with the lug and groove controlling relative axial movement between the inner and outer tubular members. The inner tubular member includes a load lug (154) on the radially outer surface thereof for abutting against an annular shoulder (160) disposed about the radially inner circumference of the outer tubular member to prevent the guide lug from exerting significant axial forces on the groove. The assembly is especially useful in downhole tools.
