NOV Brandt Venom
M-I SWACO conducted a lunch-and-learn presentation of the latest screen technology and services. The lead Drilling Superintendent for EQT Production asked that we conduct a side-by-side comparison on one of his rigs in an effort to better understand efficiencies of the M-I SWACO screen technology so he could visualize this first hand.
M-I SWACO conducted a full VIBRATORY SYSTEMS ANALYSIS AND TEST† (VSAT†) on the two NOV Brandt King Cobra VenomTM flow line shakers in an effort to identify areas of opportunity to bring the shakers back up to manufacturer specifications. Minor repairs inclusive of spring replacements were noted and the rig quickly ordered parts. Upon conducting a follow-up inspection to ensure all repairs/replacements, M-I SWACO did note the shakers were working optimally and so the screen testing could begin.
M-I SWACO Replacement Screens for the NOV Brandt Venom shaker outperformed the non-OEM competitor metal screens on several fronts:
- Screen Life
- Solids Conveyance
- Liquid on Cuttings
The Drilling Superintendent said that he received three phone calls at the end of the test:
1. The company man on location called to say he was impressed with the
fact that we ran a retort using the PVC Cutout Method capturing cuttings at the
full length of the discharge end of the shakers for a balanced collection for
testing. He was also impressed that mud from M-I SWACO screens came back as
being 18% while mud from competitor screens came back at 30% liquid on cuttings
after 12 hours of running. Then after 24 hours of running, mud on M-I SWACO
screens showed liquid on cuttings at 17% and mud from competitor screen showed
29% liquid on cuttings.
2. Third-party fluids engineer called to say he appreciated the
attention to detail M-I SWACO paid to the entire screen testing and liked the
fact that at the conclusion of the test (29 hours of straight running), no M-I
SWACO screens needed to be changed.
3. The company solids control rep called to advise that M-I SWACO
screens made his job much easier producing dryer cuttings and not having to run
back and forth changing screens out.
Additionally, EQT Production awarded M-I SWACO with screens on this rig with talks of seven additional rigs in the coming months.
