  • Modular footprint smaller than conventional drilling and workover rigs
  • Reduce mob and demob cost

Hydraulic Stand Alone Units
Cudd Energy Services hydraulic stand alone unit is a preferred choice when pressure, space, accessibility and rig availability are concerns. The stand alone package includes a work basket, hydraulic jack, stationary and traveling slip bowls, power pack, work window with walk arounds, and gin pole. Pump support is available for all applications.

Features

  • 150k, 225k, 340k and 600k units available
  • Handles surface pressures up to 20,000 psi
  • 600,000 lb lift capacity
  • 300,000 lb snub capacity
  • Smaller footprint than conventional drilling and workover rigs
  • Torque capabilities up to 20,000 ft/lb
  • Unit design complies with regulatory requirements
  • Handles 3/4" up to 13-3/8" O.D. pipe/casing
  • Engineered tong poles available to hang hydraulic tongs

Hydraulic SPACE SAVER (Rig Assist Unit)
For expedient and efficient operations, Cudd Energy Services revolutionary "Space Saver" snubbing unit brings the advantages of hydraulic snubbing to conventional drilling or workover operations.

The self-contained, 170K Space Saver unit is configured with a low-profile snubbing stack located between the hydraulic jack legs. This shortens the operating height for more efficient tubular handling and faster trip times. With only one flange connection to the existing BOP stack, the hydraulic rig assist unit can be rigged up in less than 60 minutes.

Features

  • Self contained unit is easily transported
  • Requires a 3-man crew
  • Fast rig up, job completion, and rig down
  • 170,000 lb lift capacity (200,000 lb lift capacity available)
  • 85,000 lb snub capacity (123,000 lb snub capacity available)
  • 7-1/16" 5,000 psi BOP stack
  • 11" 5,000 psi BOP stack
  • Handles 1 ½"" to 7-5/8" O.D. pipe/casing
  • Annular BOP provided for continuous stripping operation

150K Quick Jack™ HWO Unit
Cudd Energy Services 150K Quick Jack™ is a modular stand alone hydraulic workover unit configured for rapid rig ups (2-3 hours). The Quick JackT is an economical alternative to high pressure coil tubing or a space saver workover rig combination.

Features

  • Fully functional 150K stand alone hydraulic snubbing unit
  • 150,000 lb lift capacity
  • 75,000 lb snub capacity
  • 1500-3000 ft/lb rotary table
  • Guide system available for high pressure applications
  • Handles 1" - 5 ½" tubing and up to 3 ½" drill pipe
  • 7 1/16" maximum through bore
  • Handles surface pressure up to 20,000 psi
  • Personnel are isolated from suspended loads with the automated stabbing system

Rack Jack® and Skid System
Cudd's hydraulic workover professionals are continuously examining our processes to create job efficiencies for our customers. One result of these efforts is the Rack Jack® and/or skid systems used independently or in tandem. The Rack Jack® feature enables crews to standback the workstring improving trip times in and out of the well. The skid system allows movement between wells without rigging down the unit or BOP stack. Used in tandem, the Rack Jack® skidding system allows the user to move between wells without laying down the workstring.

Features

  • Suitable for land and offshore operations
  • Available with 225,000K and 340,000K stand alone HWO units
  • Large workbasket allows for a safer working environment
  • Capable of holding up to 17,000 ft of 3 ½" tubing
  • Torque capabilities up to 15,000 ft/lb
  • Gin pole can lift up to 70' BHA's weighing up to 10,000 lbs.
  • BOP trolley system allows lift of 13- 5/8" x 10M BOP stack
  • Skid system load capacity ­— 612,000 lbs
