Abstract

Production intervals in unconventional liquids rich reservoirs can be challenging. As the well matures the risk of solids and gas intrusion disrupts desired flow regime. As these mature wells are put on artificial lift to help overall production, this intrusion of gas and solids has a negative effect on pump performance. Rockies completion engineers have developed a device that utilizes existing wellbore construction equipment to help mitigate risks of solids intrusion and increase overall pump efficiencies. The device utilizes existing field proven technology from multiple product lines to form a system that can provide a high level of value to the customer.

Downhole Gas Sperator and Solids Control Device

Production intervals in unconventional liquids rich reservoirs can be challenging. As the well matures the risk of solids and gas intrusion disrupts desired flow regime. As these mature wells are put on artificial lift to help overall production, this intrusion of gas and solids has a negative effect on pump performance. Rockies completion engineers have developed a device that utilizes existing wellbore construction equipment to help mitigate risks of solids intrusion and increase overall pump efficiencies. The device utilizes existing field proven technology from multiple product lines to form a system that can provide a high level of value to the customer.

Utilizing existing WBC, Sand Control, and Cased Hole Completions equipment to develop a one trip downhole gas and solids separation device. Utilizing existing liner top equipment as a permanent datum point for all future installs. The system is deployed on a workover rig (when in production mode), and stung into the existing liner top packer (liner top release profile HR or 2RH), tension is applied against the production string, and the downhole separator is shear released from the running string. A 1.500" or 1.66" NU 30-60' long dip tube is shear pinned to the separator BHA. Once the assembly is latched into the liner top and shear released, then the dip tube is spaced out and lowered to 3-5' above the existing liner top. This will create 30-60 ft of overlap between the bottom of the (1.5" - 1.660" OD) dip tube and the top of the separator device....
