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.
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.
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.
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 An interference added to its tail means that as the cut pipe is withdrawn it collects the fishing dart and carries it back to surface.
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.
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.
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.
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.
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.
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.
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.
DAV MX™ - Emergency Shut-Off Dart
Not only does the DAV MX™ push the operating envelope further and have the best reliability in class, it also provides a totally unique back-up closing system. Should the valve become damaged by any unexpected events, users can deploy the Emergency Shut-Off Dart (ESD) which patches and seals the leak path but still provides a generous thru-bore allowing operations to continue. The ESD ultimately saves the Operator a trip out of hole.
