BDMS (Ball Drop Multiple Sleeve) System
The BDMS system is a ball drop, sliding sleeve activation systems that allows for multiple frac stages to be isolated and simultaneously fractured.It can be used in either open hole or cemented completion applications. By incorporating the hydraulically actuated Launch sleeve in the first stage, time and safety risk are reduced as differential pressure opens the flow ports. Clustered stages may be opened as the ball engages and opens subsequent Mulit-Port and standard BDMS sleeves which all have the same ball seat diameter. Additional cluster stages may be opened and fractured by dropping progressively larger balls.
The BDMS system can utilize up to 10 Multi-Port sleeves per stage, resulting in 11 individual fracture port segments within a “cluster” stage. The ports on the Multi-port sleeves are configured to ensure uniform frac flow across the cluster stage.
BenefitsPacker and sleeve combination provides for a simple open hole completion
Ball drop requires less intervention and complexity in the completion process
Multiple sleeves shifted with one ball reducing time and cost of completion
The hydraulically actuated Launch sleeve enables circulation without perforation gun
FeaturesFor sizes: 2-7/8” to 5-1/2” completions
Capable for High Temperature, High Pressure, vertical, or horizontal applications
This completion approach can be run as a tie back or incorporate a hanger packer
All components are designed to work in open hole or cased completions
Enables “cluster” fracturing where large sections are fractured with less restrictions
Expands the number of frac sites for ball drop
