Despite the fact that Drilling Innovation LLC is a manufacturer of whipstock for cutting a "window" during sidetracking, thanks to our extensive experience in export deliveries, we have the opportunity to work in other directions as well.

Despite the pandemic, work continues.

The use of hydraulic whipstocks, which do not require cement bridge, is quite a popular issue even in the current situation in the country.

In the shortest possible time, the Drilling innovation LLC specialists coped with the shipment of equipment and the mobilization of an engineer to the Customer's facility 2,000 km from the base.

From the moment of receiving the request from our Customer, no more than 2 days have passed since the equipment and the engineer were reached the rig.

Loss of drilling fluid is a downhole complication characterized by complete or partial loss of circulation of the drilling fluid during drilling.

Factors affecting the occurrence of lost circulation can be divided into two groups:

1) geological factors - the type of absorbing formation, its thickness and depth, insufficient resistance of rocks to hydraulic fracturing, formation pressure and characteristics of the formation fluid, as well as the presence of other accompanying complications;

2) technological factors - the quantity and quality of the drilling mud pumped to the well, the method of drilling, the speed of the round-trip operations, etc .; this group also includes technical equipment and organization of the drilling process.

A set of equipment for cutting a window for onr trip - a 9 5/8" hydraulic whipstock was shipped from the warehouse in Aznakaevo to Bratsk.

The set also included an overflow valve, UBHO, and reaming mill.

One more non-standard work was carried out by the Drilling Innovation specialists in the Krasnoyarsk region.

This time we had to solve the issue on whipstock setting in a 11.6" open hole. The complexity of the operation was that a large number of lost circulation zones created problems for the drilling engineers and the open hole walls were not stable, as pointed in the caliper logs from this well.
