Downhole Tools

You need equipment that can carry out workover operations and well completion processes even within unique conditions such as high pressure environments and lateral wells. Piston Well Services offers solution-oriented ingenuity in the design of several downhole devices, such as our patented BADASS and Acid Disconnect which adapt to your needs, ensuring optimal performance and efficiency.

We carry an inventory of the most robust 2-3/8 drill pipe and workstring in the industry. We also have standard ball-activated 15k disconnects, custom mills, X-overs and BPVs rated for up to 20,000 psi at the ready to get the job done.

The BADASS

In response to a growing market for lateral completions, we developed the BADASS (Ball Activated Disconnect And Sliding Sleeve), a tool that allows the lateral to be cleaned out with the production pipe. Once the bit reaches the toe, a ball is pumped to disconnect the bit, and the string is pulled back to landing depth. The tubing hanger is then landed, and the wellhead is installed. A second ball is then pumped to open the sleeve for flow.

Contact Piston for more information on the BADASS and how it can help you execute well completion on your lateral well.

The Dissolvable Disconnect
(Patent Pending)

The Dissolvable Disconnect is the latest technology we have developed that is bound to impact the market, from the coil to drilling rigs, is the dissolvable disconnect tool. 

A typical drilling BHA for extended reach wells places multiple agitators back from the bit up to 4,500 ft. If stuck, the assembly is difficult to fish because the wireline can’t run through the agitators to back off close to the stuck point. The Dissolvable Disconnect tool can be placed anywhere in the BHA. If stuck, acid is spotted across disconnect, and the string is freed. As a result, less equipment is required to fish, cutting the risk and cost to the operator.

Coil, for example, often gets stuck at the bit. The disconnection occurs above the motor/shock tools, complicating the fishing string and creating a need for washover trips. With a dissolvable disconnect placed directly above the bit or mill, acid can be spotted. The motor can be retrieved, allowing a far cheaper fishing operation; ideally running with an overshot.

Our end goal for this tool is to allow shock tools to be placed back from the BHA, where they are most effective, while maintaining the option to disconnect if the string becomes stuck. We want to keep a competitive edge by allowing faster holes across the lateral with less risk. We are in the third and final stage of lab testing the tool before proceeding to a pilot well test.
