GeoGLIDER™XTREME Case Histories

GeoGLIDER™XTREME Case Histories

GeoGLIDER™XTREME is a unique centralizer design whose major feature is the reduction of the contact area within the wellbore when running in hole.

A customer in Murmansk region was faced with the challenge of running 7 inch long string in every well on two separate turnkey drilling projects. Over the course of 10 months the 7" long string was pulled 4 times. Twice the casing had to be severed and retrieved. Since the introduction of the GeoGLIDER™XTREME Lite centralizers to this project, the 7" casing has always been run to section TD by its own weight only without the need for reciprocation or rotation.

GeoproHYDRA™PRO tubular deployment and reaming system continues to push the envelope for conventional hydraulically actuated reaming solutions.

First ever deployment of the GeoproHYDRA™ in PRO variant was a huge success for a client in Northern Russia

The D41 casing tubular deployment service involved a risk assessment and mitigation plan to land over 10,000 feet of 9-5/8 inch casing through mostly shaly geology. This solution involved the careful placement of low friction centralizers and a reamer shoe solution with a ratcheting capability.

Client in South West Nigeria sees improvement in cement quality across shoe track at landing point (horizontal)

A 7 inch GeoproHYDRA™ 3rd Generation tool with 1G7 drive system configuration was deployed in a designer (pregnant lady) sidetrack well in 8 1/2" hole for a customer in the Niger Delta of Nigeria. The customer was concerned about the tortuous nature of the borehole and ran the 7" GeoproHYDRA™ as part of their risk mitigation plan.

A 7 inch GeoproHYDRA™ 3rd Generation tool with  1G7 drive system configuration was deployed in a designer (pregnant lady) sidetrack well in 8 1/2" hole for a customer in the Niger Delta of Nigeria. The customer was concerned about the tortuous nature of the borehole and ran the 7" GeoproHYDRA™ as part of their risk mitigation plan.

The 7” GeoproHYDRA™ was made up to the shoe track and tested at surface to 150 gpm flow rate and pressure was recorded for reference. This was done to establish the operating envelope since the pressure drop rating on the liner hanger was 600 psi (standard) and 800 psi as the absolute maximum.



The liner string consisted of an 80 feet shoe track with the landing collar at +/- 120 feet from the shoe. The entire liner string was over 5500 feet long. The sidetrack window was through the 9 5/8” casing string at 6000 feet with a near vertical inclination. The final inclination at the landing point was over 88° (near horizontal).

The wellbore was slick and no reaming was required, however, due to losses while cementing the liner the customer decided to dress cement in the shoe track down to the top of the GeoproHYDRA™ to evaluate the quality of cement behind the liner. The cement quality showed better cement across the shoe track than anywhere else across behind the 7 inch liner, providing first hand evidence of the cement enhancement feature of the GeoproHYDRA™. In the past, Geopro has always claimed that our high-speed reamer shoe, the GeoproHYDRA™ was designed to enhance cement placement quality in highly inclined boreholes as the high speed rotation is expected to mimic string rotation while cementing and also create a cyclone-like fluid flux effect in the borehole that will improve cement deposition and placement. Circulating pressures were low throughout the operation.
