Services

With more than 50 years in the business and a staff of more than 30 people, Pacific Perforating offers both expertise and experience in providing perforated slotted pipe in California heavy oil operations. We keep a large stockpile of tubulars of various sizes and lengths, so we can guarantee quick service and delivery.

Our team of trained and experienced professionals have the skills, trucks, cranes and other equipment needed to bring the materials you need to your lease, when you need them, no matter where it is or how small or confined the working area might be. Slotted Liners are delivered cleaned and polished – ready to use.

 

 

Tubular Slotting

Choosing a Slot Design

Slotted pipePacific Perforating produces two styles of slots -- either straight or keystone. Straight slots are the same width on the outside and the inside of the pipe. The openings on the keystone slots are wider on the inside than they are on the outside. The benefit of the keystone profile is that it allows for the slot to be self-cleaning. We also build stainless steel screen that can be welded to the exterior of specially slotted pipes to produce an extra layer of filtering for specific ground or heavy oil conditions.

The type of slot you need is determined by soil and ground conditions. Generally speaking, the width of a slot should be roughly two-to-three times the diameter of the sand you are drilling through. By using circular, high-speed steel saws and cutting into the pipe from the outside, the slots are slightly longer on the outside than they are on the interior walls. This creates a funneling effect and helps the oil flow faster.

We generally cut liners with an even number of rows so each row can be staggered. Limiting the amount of material we remove to 3% of the total surface area helps preserve the pipe’s strength and structural integrity, and also make the drainage and filtering activity more efficient.
