Functionality Report: Brazil: One certain GN-3 Shaker Outshines 3 in Profitable South America Debut

The new-generation GN-3 triple USA desilter was engineered to supply operators an ideal mixture of higher efficiency, adaptability, enhanced operate atmosphere and reduction in space specifications. Operating in each the progressive and balanced elliptical motion, the compact GN-3 shale shaker is exceptional in that it may well adapt speedily as drilling situations and cuttings volumes modify.

To quantify the functionality and cost benefits of the GN-3, when compared with conventional shale shakers beneath the ever-changing drilling circumstances and specifications, an aggressive comparative field trial was undertaken about the Diamond Ocean Star semi-submersible rig, which generally employed 4 cascade shakers. The test may very well be carried out throughout the remainder inside the OGX 1-OGX-28-D-RJS exploration correctly in Brazil?ˉs Campos Basin. The field test represented the initial use around the GN-3, offshore in South America.

For the comparison, one unique of one’s current rig cascade shakers was removed and replaced with an GN-3, which was installed with no HSE incidents. This configuration allowed the three rig shakers to become applied in conjunction with all the GN-3, because of this enabling the collection of aggressive comparison information and facts. The key objectives in the test had been:

Test the flow handling capacity in the GN-3 desilter in comparison using the existing rig cascade shakers.

Prepare a qualitative assessment around the solids handling and conveyance capacity around the GN-3 shale shaker in comparison with the current rig cascade shakers.

Measure the screen life of your GN-3 shaker and examine it towards the screen usage of the existing rig cascade shakers and historical GN-3 screen usage data 3 tests had been performed which involves all round functionality, screen life and QHSE perspectives, the single GN-3 shaker surpassed the three existing rig shakers in all the head-to-head comparative evaluations. Even when outfitted with bigger API designation screens, the GN-3 did not expertise the regular flow restrictions within the previously employed four-cascade shaker configuration and correctly processed in the complete nicely flow cost. The GN-3 exhibited its capacity to adapt conveniently towards the rapid ROP encountered in each the top rated and intermediate successfully intervals.

For the duration of drilling from the 12 ? in. section, all the shakers removed a cumulative 561.75 bbls (89.311m3) of cuttings, excluding any washout around the open hole. The single GN-3 shaker processed 75%, amounting to 421.31 bbl (66.98 m3) from the total cuttings removed within the 12 ? in. hole, even though the 3 rig cascade shakers combined processed the remaining 140.44 bbl (22.33 m3).

Further, throughout 12 ? in. interval, the screens with all the 3 existing cascade shakers skilled catastrophic failures, even though the GN-3 screens were repaired very simply and returned to service. Whilst the GN-3 processed 75% of one’s total flow in each the intervals tested, in comparison with all the three cascade shakers it accounted for only 33% in the damaged screens that had to be scrapped. When calculated for comparative screen life, the GN-3 screens realized a 12-fold higher service life and utilization compared to the rig cascade shaker screens, thereby saving drastically in connected screen cost.

The general general overall performance with all the GN-3 via the comparative field trial was practically nothing at all speedy of exceptional, effectively validating its operational and economic benefits. Via the trial, a single GN-3 appropriately processed nearly 300 additional bbl of cuttings than 3 cascade shakers combined employing the utmost in reliability and screen life.
