TOP DRIVE SUBS

These typically are pin x pin with usually a 6 5/8″ Regular pin x whatever connection is on the drill pipe being run. Please provide us the following info: OD size, ID size, shoulder to shoulder length (s/s, STS) and connections needed. Typical sizes are 7 3/8″ OD 2 1/2″ ID and 9 1/4″ s/s length as an example.

CROSSOVER SUBS (X-OVER / XO SUBS)

A crossover can usually have any connection configuration and will either be a straight OD sub or a bottle neck sub. Customer information needed to make these is going to be, OD size, ID size, shoulder to shoulder length, bottle / fisher neck OD & length and connections needed. If the customer does not specify more than connections, we will make them according to API 7-1 type A or B subs.

WEAR SUBS / BURN SUBS / TEST PLUGS

These types of subs are usually short XO subs, usually anywhere from 8″ to 24″ shoulder to shoulder. They are meant to be used until the connections are worn out and then replaced, the longer ones can usually be re-cut unless they must have a specific shoulder to shoulder length. Customer information needed to make these is going to be, OD size, ID size, shoulder to shoulder length and connections needed.

BIT-SUBS

A Bit-sub is usually going to be box x box with one end always have a Regular connection and the other end connecting to a DC or HWDP. They attached to the bit and are at the end of the string. These will have a float bore on the Regular side. Customer information needed to make these is going to be, OD size, Float Bore size, shoulder to shoulder length, bottle / fisher neck OD & length and connections needed. If the customer doesn’t specify more than connections, we will make them according to API 7-1 type A or B subs.

FLOAT-SUBS

Float-subs are similar to Bit-subs, but they are usually at the beginning of the string. They will usually be a pin x box sub with a float bore on the box end. Sometimes people will confuse them with bit-subs and vice-versa. Customer information needed to make these is going to be, OD size, Float Bore size, shoulder to shoulder length and connections needed. If the customer doesn’t specify more than connections, we will make them according to API 7-1 type A or B subs.

LIFT SUBS

These subs will have one connection that usually attaches to a DC, they will have an elevator recess either tapered or squared. Customer information needed to make these is going to be Elevator recess size and connection needed. We will make them according to API 7-1 unless they have their own drawing for what they want.

PUP JOINTS / DRILLABLE  LIFT SUBS

These are like short joints of drill pipe always with a box and a pin. As of right now we can make them up to 10 feet long. We will soon have the capability of making these up to 15′ long. Pup joints will have the same DP connection on each end and a drillable lift sub will have the DP connection on the box end and a DC connection on the pin end.

Customer information needed to make these is going to be, tool joint OD, tool joint length, tube OD, tube length, ID, s/s length and connections needed.

These are pretty customer specific and there is no common way to make them a sketch or a drawing usually helps, but the person ordering them can usually verbally describe what they need.

PORTED SUBS

These tools are usually for testing, they are usually a short sub with a 1/2 NPT thread on the side with the same size connection for the box and pin.

Customer information needed to make these is going to be, OD size, ID size, shoulder to shoulder length and connections needed.

PUMP IN SUBS

A pump in sub will usually have a DP pin and a 2″ 1502 female end (pin thread). They will have a 2″ ID and the OD is usually the tool joint OD (???) of the connection. They are usually anywhere from 18″ to 36″ long, but it is up to the customer how long they want it. As of right now we can only do the straight pump in subs, there’s also side entry subs which will have the 1502 connection cut on the side, we do not have a CNC mill to make these now.

BENT SUBS

This type of sub will have a pin and a box with usually the pin connection cut on a 1.50 to 30 angle from the centerline of the box. They are used for directional drilling but have been mostly replaced with adjustable mud motor tools. Customer information needed will be OD, s/s length and connections needed, ID will usually be smaller to accommodate for the pin tool joint and connection being cut on angle.

OTHER TOOLS

Since we have a capable machine shop, we can handle a variety of other types of work. Companies that use/make coiled tubing parts, completion tools, packer parts, mud motor tools, fishing tools, pump parts or anything that’s round and needs threads, precision OD and bores, 0-ring grooves, holes drilled and tapped, mill slots or other mill work are also things we can do. If you have a project to consider outsourcing, please provide us either a spec sheet or drawings and we will be eager to quote!
