FracJet-Volga drilled three horizontal laterals with a 2-7/8” coiled tubing string while controlling the well trajectory. A total of 4,311 feet was drilled in high-H2S conditions.

The company developed and implemented the CT drilling technology that combines drilling and coiled tubing workover techniques. We made a mobile drill mud cleaning system, a blowout prevention complex, an LWD system, a BHA and other components required to successfully perform the CT drilling operation.

The work was complicated by high levels of H2S (up to 36%), as well as 18% CO2. A customized coiled tubing string was manufactured to the FJV specifications to withstand the harsh conditions of the Astrakhan field. It was a unique operation of well logging in a flowing well.

FJV has designed a jet pump to de deployed on coiled tubing. The packer in the pump allows the crew to operate without employing a workover unit, i.e. directly in the tubing hangers.

In 2023, the design was improved to reduce the impact of the gas factor. The equipment is manufactured for the 2-3/8”, 2-7/8” and 3-1/2” tubing. Field trials have been successfully completed by the experts of FracJet-Volga and Gazprom Dobycha Orenburg.

FJV has completed acid jet drilling of sidetracks with trajectory control at the Eastern block of the Orenburg oil and gas condensate field. The work was significantly complicated by harsh corrosive environment, and we had to use hydrochloric acid compositions as a drilling fluid.

For these jobs, the company had developed and used highly durable downhole equipment capable of withstanding high-H2S conditions - jet nozzles, knuckle joints and wireline well control devices. FJV Chemical Lab designed compositions to combat asphalt, resin and paraffin deposits in the wellbore, as well as acid compositions to heat up the wellbore.
