DAV MX™ CircSub
The DAV MX™ is a multi-function, multi-cycle circulating sub that delivers significantly improved performance and is simple to use. Run in hundreds of wells every year and recognized for its reliability, resilience and versatility, the DAV MX is the ultimate downhole circulation tool.
- Simple and reliable - unlike conventional balls, DAV MX Darts will not blow through on opening, therefore can be pumped at much higher speeds
- Over 2100 runs globally saving thousands of hours across a wide range of applications
Providing double float protection and eliminating the need for top-filling, running the Self-Filling Float operators can achieve significant time savings and improve safety.
- Save up to 18 minutes per 1,000 feet run in hole
- Compatible with shallow hole testing
Self-Filling Float Trigger™
The Self-Filling Float (SFF) Trigger is the simplest and fastest float system available for tripping into hole. It provides all the benefits of the original SFF including time savings of up to 18 minutes per 1,000 feet. However, with automatic depth-arming and pump-triggering, the SFF Trigger increases capability and simplicity even further.
- Saves up to 18 minutes per 1,000 feet run in hole
- Self-fills even when the tool is armed
DURA Drill Float™
The Double Upper Reserve Activating (DURA™) Float provides operators with superior well control on a number of contingency applications. Running the DURA, operators benefit from a dormant large bore float situated above the BHA which can be rapidly activated by pumping a dart from surface.
- Superior double float protection providing the ultimate contingency
- Allows self-filling and through bore until activated
Providing a high-quality contingency string barrier, the DICV Max range also features the largest through bore options in the industry and is available in any drill string connection.
- Superior contingency well control
- Compatible with Churchill products and other third party tools
When self-filling is not an option, the TopJet provides operators with a quick, simple and safe method of top-filling pipe when running-in-hole.
- Save up to 10 minutes per 1,000 feet run in hole
- Improve safety – Reduce spill hazards and benefit from a cleaner and safer rig floor
The unique HyPR HoleSaver™, the world’s first hydraulic pipe recovery system, enables operators to sever their drill-string in just a few hours and recover quickly and safely from stuck pipe incidents.
- No additional topside equipment or personnel required
- Faster, simpler, safer pipe recovery
The Drift Catcher is a high quality downhole pipe drift verification tool. It provides operators with rapid results and eliminates the need for risky and time-consuming drifting in the derrick or using ad-hoc in-hole wire tail drifting methods.
- Fast and accurate drifting
- Eliminate the threat of dropped objects when drifting from the derrick
Especially effective during milling operations, the Mud-Shear Sub is a simple solution that requires no topside equipment and delivers significant time savings when mud conditioning irrespective of flow rate or fluid type.
- Save an average of 1 hour for every 1,000bbls of mud sheared
- Easily configurable to suit any flow rate and viscosity
Pressure Test Sub MX™
The Pressure Test Sub MX is a simple yet accurate way to perform multiple pressure tests on the string with the capability to regain full circulation after each test.
- Shearing accuracy of up to 99.6%
- Regain full circulation after each test
Drift Catcher™ - Volumetric Drift
Allows the drifting process to simultaneously gage the pipe volume. In certain string/liner volume ratios there may be a high risk of over displacement especially if non-bumping plugs are run. The volumetric drift simulates cement plug delivery thereby giving an additional data reference point. Over-displacement risk is detected by the volumetric drift landing out earlier than expected. Volumetric...
Drift Catcher™ - Choked Drift
Used in hundreds of wells, this drift is perfectly designed to reduce dropped object risk and give a confirmed and accurate drifting process. The unique design with a pressure confirmation ensures a good drift has landed in the catcher below. Rapid drift confirmation No false positive (clear pressure confirmation) Pipe friendly soft nose Retrievable Ability to pump after...
HyPR™ - Cementing Dart
When time is at a premium the cementing dart will give immediate side-tracking in a stuck pipe situation. After it has cut the string free the dart will remain in the fish. With the upper string now free and clear, cementing over the fish can begin right away. Ceramic Diverter Jet Leaves a clear pipe to allow cementing Fishable *Please refer to full operating instructions...
HyPR™ - Fishing Dart
When attempting to fish the BHA is preferred, this dart leaves a clear unrestricted access to the fish after it has cut the string free. An interference added to its tail means that as the cut pipe is withdrawn it collects the fishing dart and carries it back to surface. Ceramic Diverter Jet Leaves a clear fish Fishable *Please refer to full operating instructions...
Pressure Test Sub - Pressure Test Dart
With a simple landing sub and catcher installed in the string Pressure Test Darts can be dropped in to pressure up the string above and test its integrity. At a pre-determined pressure the dart will shear out and fall into the catcher below. Adjusting the shear pins installed allows various pressure levels to be tested before resuming flow to the bit. User configurable on rig 1200...
Self-Filling Float - Float Activation Dart
The smallest and simplest dart in the range, ergonomically designed to pass through all of the upper string and drop into the dormant float sub and shear it into activation. Universal for poppet and flapper type *Please refer to full operating instructions before use, these notes are summary highlights only.
DAV MX™ - Standard Diverter Dart
The standard method for DAV MX™ bypass, delivering 100% BHA bypass with in a hold-open mode. The default dart to use unless looking specifically for split flow or full pressure relief. Rapid 100% bypass Selection rate 56% 12 inches in length Best for*: Losses, Tripping Out Dry and Jetting BOP’s *Please refer to full operating instructions before use,...
DAV MX™ - Split Flow Dart
The best method for DAV MX™ hole cleaning, by delivering some flow to the bit also in a hold-open mode. This BHA flow gives cooling for rotation friction in the BHA as the string which is useful for better agitation and string management. Rapid split flow bypass Selection rate 32% 12 inches in length Best for*: Agitated Hole Cleaning and Tripping into Hole. *Please...
DAV MX™ - Alternative Diverter Dart
Shorter than the Standard Diverter Dart, this dart allows the valve to close with the pumps off, closing off the annulus. Although it makes the valve do more work, it may be preferred in certain situations to keep the annulus shut out when the pumps are off. Rapid 100% bypass Selection rate 12% 8 inches in length Best for*: U-tube avoidance *Please refer to...
DAV MX™ - Universal Closing Dart
Whichever opening dart is used the Universal Closing Dart will shear it out to close the DAV, with both darts landing in the catcher below. It operates with full bore sealing above the opening dart to provide maximum load onto the concentrator button on the lower dart to shear out the pins. Rapid return to thru-bit flow 8 inches in length *Please refer to full...
DAV MX™ - Ultra Series
The Ultra Series Dart is capable of high speed activation, allowing it to be pumped in at up to 400gpm which is ideal for ERD (Extended Reach Drilling). It also has a low shear out pressure (600PSI) which makes it the perfect dart for delicate formations or coring runs. Fastest 100% Bypass (pump in at upto 400gpm) Soft Shear – Ideal for delicate formations 12...
