Abstract: A method of stimulating a subterranean formation using a completion string having a wall with burst disks formed therein, and a well treatment tool connected to and in fluid communication with a treatment tubing having a conduit therein. The tool has at least one opening formed straddled by two interval isolation devices. The treatment tubing is fed into the completion string and the well treatment tool is positioned such that the isolation devices straddle the set of burst disks. Treatment fluid is then pumped under pressure through the conduit, and treatment fluid ejecting from the opening in the tool increases pressure within a space within the completion string between the two interval isolation devices to rupture the burst disks. Subsequent to the rupture of burst disks, the treatment fluid passes into an isolated annulus interval and then stimulates the formation. This invention also discloses a burst disk in a completion string wall defined by a discrete section of string wall of reduced thickness. This section of reduced wall thickness is defined by an end wall of a bore formed partway through the completion string wall.

Abstract: The invention relates to a multi-purpose device and a method to dispense and/or blend the correct dosage of a given liquid concentrate or agent into a larger volume of a host liquid in order to produce the desired blend of the two at any given volume. The device consists of a container for concentrate of a size suitable to the volume of the container of the host liquid, an immersible or remotely-mounted electric pump to transfer the desired dosage amount from the concentrate container to the host volume container, and an electronic pre-programmable module that will accumulate data to determine the concentrate dosage required.  The module will cycle the electric pump to deliver said dosage to the host container. The device may be mounted with the dosage tank vertically or horizontally disposed at any angle.   The device in various embodiments is suitable for such purposes as automatic dispensing of pool chlorine, wherein the programmable module accepts either pH or Specific Gravity readings from an included reservoir and cycles the pump accordingly to adjust the chlorine/water blend as required. In another embodiment it is an automatic dispensing device for fuel additives as used in heavy truck-tractor, construction, marine, rail and mining equipment engine applications, wherein the programmable module senses fuel level readings on a timed cycle basis as fluid level decreases and dispenses concentrate proportionately as fuel level is increased by refueling.
