OVERVIEW

The PinPoint Injection (PPI) packer is a retrievable, treating, straddle packer that features a one foot spacing between packer elements. This spacing helps to ensure that the maximum number of perforations within a long producing interval can be broken down to accept stimulation fluids uniformly. Once the entire zone has been broken down individually, a massive treatment can be performed more effectively.

During assembly, the PPI packer conversion kit is installed between the RTTS® hydraulic slip body and the RTTS packer mandrel. This kit contains all parts required to convert an RTTS packer to a PPI packer, except RTTS packer rings and the spacer ring required for the upper packer element.

Adapters are provided to run 2 7/8-in. (7.00 cm) EU tubing for spacer if intervals greater than 1 ft (30.48 cm) are required. A typical PPI packer toolstring consists of the following tools (top to bottom):

» RFC® retrievable fluid control valve » RTTS® circulating valve » PPI packer » Collar locator

The PPI packer has a straight J-slot drag block body. The collar locator, if used, can be run either above or below the PPI packer. The RFC valve retains acid used to break down perforations in the tubing as the PPI packer is moved to the next setting point.

Fluid passage through the center of the bottom packer is closed off with the retrievable plug or ball included in the conversion kit. The retrievable plug or ball can be run in place with the PPI packer or can be dropped from the surface after the tools have been run in.

After the RFC valve is removed, the retrievable plug passes through the RFC valve seats. If a ball is used, it must be reversed out or brought out with the toolstring.

FEATURES AND BENEFITS

» Spacing between packer and elements » RTTS packer reliability is built into the PPI packer » Adapters allow for spacing intervals greater than 1 ft » Provides more thorough stimulation of the producing interval » Allows the collection of more detailed formation data for planning the main treatment

» Treatments can be performed through the same tool with one trip in the hole

OPERATION

The tool is run slightly below the required setting position to set the packer and is then picked up and rotated several turns. If the tool is on the bottom, only a quarter-turn is required. However, in deep or deviated holes, several turns with the rotary could be necessary. Once the setting position is established, right-hand torque is held until the mechanical slips on the tool are set and can start taking weight.

After the tools are run in the well and bottom perforations are located, the retrievable plug or ball and the RFC® III valve (if not run in with the tools) are dropped.

The lowest perforations are straddled, broken down, and injected with treatment fluid. As the packer is moved up the casing, the operator selectively straddles each set of perforations in 1-ft intervals. The bypass is opened to allow pressure to equalize across the bottom packer. Usually 1 bbl of acid is injected in each set of perforations. If perforations communicate above the top of the packer before 1 bbl of acid is displaced, injection is stopped, the packer is moved, and the excess is injected into the next set of perforations.
