Fishing Services

We use a proven set of procedures during fishing operations, documenting operations every step of the way. We gather as much information as possible right from the beginning, ensuring all changes are well-communicated throughout the progression of the job.

Downhole conditions like deviation, high temperature and pressure, H2S, CO2, sand and scale can compound the difficulty of fishing operations. We are experienced in working in these environment types and can provide cost-effective, reliable recommendations to proceed - from personnel and pressure control equipment to line choice and necessary tools.

Wireline tools used for fishing operations are varied depending on the application and can be custom built. Our fishing operation tools and tool string components include:

  • Bailers
  • Blind box
  • Broaches
  • Centralizers
  • Compounder

Horizontal Wireline Operations

Bonnetts Wireline tools in truckBonnetts Wireline is experienced in horizontal wellbore sections in both pump down and static environments.

Our pump down operations use varied tool string components, allowing for upward jarring capability during fishing operations. We have also performed pump down memory logging operations in tubing and casing while our innovative high-deviation roller assemblies allow us to work closer to horizontal that at any time in the past.


Slickline perforating is most commonly done on tubing and can be performed either mechanically (by cutting a hole in the tubing wall) or with a shaped charge. Our perforators never leave debris on the back side, avoiding problems leading to tool or casing damage.

Our supervisors are trained and certified in the safe handling of perforator explosives. Our explosive perforators do not burn holes but punch clean, round holes of a specified diameter.

They have many uses, such as:

  • punching holes to circulate and kill a well
  • draining tubing
  • lifting water from low-pressure gas wells
  • circulating out sand or mud
  • opening zones
  • operating plunger lift installations

Kinley Tools & Perforators

Kinley tools are highly regarded within the industry, and we are proud to be the exclusive provider of Kinley products in Canada.

The Kinley Perforator can be used to punch a round, clean hole ( ¼" - ¾" diameter) to circulate and kill the well, drain the tubing, prevent pulling out a wet string, circulate out annular sand bridge, open alternate zones when sliding sleeves can’t be opened, or in plunger lift installations.It can also be used to install check valves (up to ¼" diameter) or orifice inserts to provide a one-way flow for inexpensive gas lift, chemical injection, or to circulate hot oil for paraffin removal.

It is available for most sizes and weights of pipe and coiled tubing (1.315" - 7" OD) and performs at temperatures up to 160°C (320°F) and at pressures as high as 72,000 kPa (10,500 PSI) on both slickline or electric line. It is safe to operate with no danger of damaging the casing, and is even counter-balanced to always fire toward the high side of a deviated well, avoiding penetration of adjacent strings.

Reservoir Pressure and Temperature Monitoring

When you need to know what’s going on downhole, pressure/temperature gauges may be the answer.

We understand important your data is. That’s why we only use the most reliable downhole gauges - designed for any pressure and temperature - and innovative techniques that have been put to the test in some of the most intricate operations and hostile environments.

Time is critical, and we strive to provide data reports within 24 hours. All our trucks are capable of sending data from location with the capacity to generate field reports in electronic or hard copy formats right in the truck.


Redneckz Wireline EquipmentWhen you need to unload fluid or initiate flow, Bonnetts Wireline has the knowledge, experience, and equipment to tackle any swabbing job.

We use a variety of mandrels, ranging from 3/4˝ to 3 1/2˝, that can swab from 1½˝ coil tubing to 7½˝ casing. We also have a wide selection of swabbing cups to meet the challenges of any in-line situation.

RF electronic dead weights are equipped on every wireline unit. The dual pressure sensors allow real-time monitoring of both tubing and casing during swabbing operations. All data is backed up on the unit and a pressure graph can be printed onsite.

Downhole Choke Sizing

Our in-house expertise and proprietary software can help correctly size downhole chokes in the start-up and initial production phase of new wells. We get it right the first time, eliminating the trial and error typically associated with running downhole choke and saving you time and unnecessary expense.

Wellbore Modelling

Our wellbore modelling services can go hand-in-hand with downhole choke sizing, or as a separate service to troubleshoot production issues. We use wellbore configuration and flowing parameters to better understand current downhole flowing conditions. This information is then used to troubleshoot inflow issues, tubular problems or constraints as well as facility take-away impacts.
