Mills

Taper Mills

Crossover taper mills utilize the smaller diameter, lower-mill end to enter a collapsed section of casing. Then, through a combination of spudding, rotating action, the carbide covered reamer-edges mill away the undersized section to full mill diameter. The taper mill is equally effective for deburring whipstock windows. Available in OD’s from 3 ¼” to 12 ½” and in 16” to 54” lengths.

The cutting surface is covered with cutting grade tungsten carbide in a nickel-silver matrix. This results in a sturdy, impact resistant tool. The cutting surface is self-sharpening for maximum useful life. The circulation ports are designed to efficiently remove the cuttings while cooling the cutting surfaces.

Crossover mills are simple and easy to use. Tag the fish and pick up 2-3 feet. Rotate at 80-120 RPM and lower slowly to contact fish. Continue rotating and apply approximately 2000# per inch of mill diameter. For example, an 8 ¼”OD mill would run with 2,000 x 8.25 = 16,500#. Please note that varying weight and rotary speed may improve results.

Crossover Safety Joints

The Crossover Safety Joint is built tough to provide safe and easy release and make-up whenever disengagement becomes necessary. This tool was designed to transmit torque in either direction when placed in the drill, fishing and washover string.

Operational Components

The Crossover Safety Joint consists of a pin section, box section, and a friction ring. The internal connection of the safety joint is a coarse acme thread to facilitate easy backoff and reengagement. A knurled ring between the box and pin section maintains torsional integrity until backoff procedure is initiated. An O-ring seal contains pressure while the safety joint is made up.

Operation

To disengage to Crossover Safety Joint, place pipe in tension and apply left-hand torque. Hold torque while slowly lowering pipe until safety joints break. Continue to unscrew safety joint to the left.

To reengage the Crossover Safety Joint, lower pipe until top section of safety joint lands on box section. Apply one point of weight. Rotate left one or two turns. Then, rotate to the right until torque builds up indicating safety joint is made up.

Boot Basket / Junk Basket

All Crossover junk/boot basket bodies are made from materials heat treated to drill collar specifications. All connections are protected by a phosphate surface coating to minimize galling on initial makeup.

Impression Blocks

Crossover impression blocks have a soft lead bottom section which when set on top of the fish and string weight applied, an accurate indication of the fish and location can be obtained. This allows the operator to select the correct fishing tool for the job there by saving costly trips in and out of the hole.

Rope Spear

The Crossover rope spear is one of the most reliable and efficient tools of its type. The smallest tools, used for retrieving wireline, are of solid construction. The larger tools, for retrieving control line and rubber control line protectors, have a through bore for circulation purposes. These tools are utilized in offshore completion workover operations. The tools feature a simple design with barbs welded onto the shank. The rope spear can be ordered either straight or crankshaft type (as pictured).

Core-Type Junk Basket

The Crossover core-type junk basket is a rugged junk fishing device, using either a mill shoe or flat bottom type shoe in conjunction with two sets of free revolving finger type catchers. The catchers are of rivetless construction. They may be easily redressed on the job, eliminating the necessity of returning them to the shop for replacement.

The upper catcher is designed to effectively break the core which is cut by the shoe. The fingers extend only halfway to the center. The lower catcher has alternately short and long fingers which extend almost to the center of the tool to effectively collect and retain odd pieces of junk or cores.

Alternate mill shoes available are the Type B and Type C. The Type B is similar to Type A in design, but with Sintered Tungsten Carbide dressing. The Type C is flat bottomed and dressed with Sintered Tungsten Carbide. Other shoe types are available. Operation of the Crossover junk basket is simple, requiring only slow rotation and circulating fluid, to retrieve junk.

Reverse Circulating Junk Basket

A major problem impeding drill operation is the accumulation of junk on the bottom of the well. Rock bit cones, bearings, broken slips, bits of wireline, various hand tools, slivers and debris from twistedoff drill strings, and mill cuttings are just some examples of the type of junk that can be recovered by any one of the Crossover junk recovery systems.

Reverse Circulation Junk Basket

The reverse circulating junk basket (RCB) is a superior tool for removal of such items as slips, hand tools, and any other small pieces of junk form the well. The RC uses reverse circulation to aid in the recovery of debris.

Operational Components

The RCB consists of a reversing sub with intergral ball seat and reversing valve, a barrel, jund catcher, and mill shoe.
The reversing valve on the RCB is a permanent part of the tool and requires no maintenance other than normal clean up between jobs.

Accessories

Two types of shoes are available to fit the Crossover reverse circulation junk basket.

Operation

The junk basket is run into the hole. When bottom is reached, normal circulation is begun. The basket is slowly rotated. A ball is then dropped and pumped down to indicate circulation at the tool.

The coring action is then begun. This, combined with the reverse circulation, guarantees that any junk on the bottom is pumped up into the barrel and caught by the catcher assembly. The tool is removed from the hole after cutting 24 inches of core.

Washover Pipe

A washover pipe is Casing or Pipe shorter in length than a standard tubular string. Made of large-diameter pipe with a cutting surface at the tip, washover pipe is run in the well and then the cutting edge grinds the fish to a smooth surface and continues normal operations. Washover Pipe is manufactured to the following specs connections, lengths, weights and material grade.

Crossover washover pipe has a two-step, double-shouldered thread joint with flush outside and inside diameters. This buttress-type thread assures quick makeup and high torsional strength. A wide assortment of sizes is available ranging from 3 ½" to 20".

View specification guide

Drive Subs

Drive subs are used to provide a crossover connection between the Drill Pipe String and the Washover String.

Rotary Shoes

Crossover rotary shoes are manufactured from specially tempered steel to provide the ultimate in toughness and durability. They are used to cut a clearance between the fish and the wall of the well bore. Each shoe is tailored to fit a particular downhole need and normally is run on the bottom of one or more joints of washover pipe. Shoe design is dictated by whether it cuts on the bottom, on the OD, on the ID, or any combination of these. When hole sizes permit, additional clearances can be cut using side ribs, thus providing greater circulation.

Washover Safety Joints

The Crossover washover safety joint is used in connecting drill pipe to your washover string. It provides a dependable means of releasing the drill pipe from the washover pipe if the washover string becomes stuck.

The lower half of the washover safety joint remains with the washpipe when parted and is full bore to match the washpipe, making subsequent re-entry of other tools possible. A coarse pitch safety thread, in combination with the friction ring, assures prpoer release when required.

Washover safety joints are made from heat treated alloy steel and are stronger than the pipe that they are designed to run on.

The safety joint should be made up properly in the string. This is done by making up the lower half into the washpipe. Make up the top half into the lower half with the same torque as applied to the washpipe connections.

To release the safety joint, bump down sharply on the safety joint with drill striing while holding a safe, left hand torque. Raise the string slowly while maintaining torque. The upper half will unscrew from the lower half, and the friction ring will remain with the retrieved upper half.

‘To re-engage the joint, carefully feel for contact with the lower half, then appply a small amount of weight. Make one revolution to the left, then turn slowly to the right, while maintaining the small amount of weight. An increase in torque will signify that the joint has made up.

Lift Plugs

Crossover lift plugs are designed to give an efficient method of handling washover strings and have a sufficient shoulder diameter to support handling of the washover string. They are available in all thread types and sizes.

Casing Rollers

The CROSSOVER CASING ROLLER is used specifically to recondition and restore buckled, collapsed or dented tubing and casing to their normal internal diameter and roundness. It is designed to enter into the smaller I.D. of the damaged casing. As it is rotated and forced downward, it exerts lateral pressure on the casing to restore it to its normal I.D.

Construction

CROSSOVER CASING ROLLERS are manufactured from alloy steels selected for their ability to resist wear.

The Roller consist of an eccentric Mandrel upon which are mounted a series of Rollers and a tapered Nose Cone. The upper end of the Mandrel is fitted with a threaded box connection for connection to the drill pipe. The tapered Nose Cone locks all Rollers in place on the Mandrel by large ball bearings running in deep grooves in the Mandrel and the Nose Cone.

The design of the Roller permits the use of interchangeable Rollers to be used on each size Mandrel. The large bearing areas between the Rollers and the eccentrics effectively reduce bearing pressures, therefore increasing tool life.

Operation

Moderate to heavy weight should be applied during operation. The use of too little weight, with high rotational speeds should be avoided. Light weight with high speeds tends to wear the rollers without straightening the pipe. If insufficient weight is available in the running string, drill collars should be added. The best guide to the amount of weight and rotational speed to use is experience; as long as steady downward progress is made by the Casing Roller, the weight speed ratio is giving the proper results.

Badly damaged casing will require the maximum amount of weight for the Roller to enter into and straighten the casing. The rugged construction of the Crossover Casing Roller allows the operator to apply the maximum amount of weight and torque without damage to the tool.

CIRCULATION MUST BE MAINTAINED DURING THE OPERATION.

Wireline Grabs

The Crossover wireline grab is one of the most reliable and efficient tools of its type. The smallest tools, used for retrieving wireline, are of solid construction. The larger tools, for retrieving control line and rubber control line protectors, have a through bore for circulation purposes. These tools are utilized in offshore completion workover operations. The tools feature a simple design with barbs welded onto the shank. Wireline grabs can be ordered either straight or crankshaft type (as pictured).
