• Identify your application
• Choose the matching Smart Dart™
• Pump it into place quickly
• Start Circulating

All the Smart Darts™ are fully labelled with their applications and a single dart sets the tool quickly whatever the application.

The DAV MX™ is the only tool that can be set in a single shot for any application.

The Standard Diverter Dart ensures that no LCM contamination can possibly enter the BHA during spotting. By latching and sealing into the valve, the dart ensure that even at high angles there will be no lifting exposure. Furthermore the darts act as a non-return for debris entering through the bit so that u-tubing LCM invasion is not a risk. After curing pump a closing dart and drill ahead.

Alternatively use the unique hold-open feature of the Standard Diverter to spot the pill and then trip out dry without implementing a closing cycle at all. This will allow you to run back in with new cheaper assembly more rapidly for more aggressive formation repairs.

All of these superior features are combined with the 'Quick-Set' 100% bypass functionality, which make the system the fastest way to start curing loss with a CircSub.

Any of the darts provide boosted hole-cleaning, you can choose:

• Split flow dart - To spin pipe then trip dry
• Split flow dart - Pressure relieved pumping out of hole
• Standard diverter dart - Circulate and trip dry
• Well control dart - Circulate then close prior to tripping

All of these modes are available 'on the fly' with a Smart Dart™ to set the configuration in a single shot.

In applications such as spotting LCM or hole cleaning and where well control is a big concern the Well Control Dart is the best option. This might be for example when high levels of gas are being seen in mud returns.

Uniquely, the dart will give 100% bypass of the BHA when pumping, but with with pumps off, the ports will shut out the annulus with the dart remaining securely latched and sealed onto its seat.

Boosted circulation from the DAV MX™ can deliver high flow rates into the BOP cavities, this can be performed as an extension to the end of run hole cleaning or the valve can be activated and de-activated for each function.

Most effective is when the Split Flow Dart is used to hole clean quickly at TD, then left to drain the string during POOH before finally circulating debris out of the BOP cavities with the flow to/from bit ensuring any cuttings are pushed up to surface.

The unique latching of the Split Flow Dart ensures that the valve remains held open at all flow rates and pressures, so it can be used at depth and near surface immune to varying hydraulics with no need for any tool pre-configuration.

The Standard Diverter Dart can release pipe from this situation. By holding open the ports the dart permits u-tubing which can be exploited to lower the static pressure in the well. As the pressure reduces the sticking formation rebalances and releases the pipe.

This unique feature is courtesy of the darts ability to latch firmly into place and hold the ports open when the pumps are off. The design is such that there is little danger that the u-tubing flow cannot unset the hold-open.

The Standard Diverter Dart will gravity feed into the valve at angles up to 55 degrees when circulation has been lost. After arrival of the dart circulation can be recovered by pressuring open the ports.

The 100% bypass and density characteristics of the dart are the keys to providing the capability in this application.

The Standard Diverter Dart will be ideal for tripping dry as would the Split Flow Dart. This sequence would normally follow a hole cleaning cycle so in practice the cleaning requirements might determine the dart used (see hole cleaning)

The hold-open latch is what provides the functionality for this application, with the selected dart setting the tool in a single shot.

The Standard Diverter Dart is also useful for preventing pressure build up when running back into hole. Running in a few stands before setting the tool held-open will ensure pressure is equalised between annulus and pipe naturally.

The Split Flow Dart would also be an option, depending on application, as it is the hold-open latch that provides the functionality for self-filling.

The Split Flow Dart will hold the ports open as flow is passing through the ports from the annulus. The Standard Diverter Dart would also be a viable option in this scenario.

Again the hold-open latch is what provides the functionality for this application, with the selected dart setting the tool in a single shot

The Split Flow Dart fully relieves pressure in all directions, so that as the pipe is moved in and out of hole pressure can equalise through the ports. Surge pressure relief through bit will occur if the assembly is not floated.

The hold-open latch with choked thru-bore is what provides the functionality for this application, with the selected dart setting the tool in a single shot.
