Bottom hole pumps

Winters and Warren of Amoco teach diamond bit hydraulic lift off and two procedures for ascertaining the numerical value of bit lift off while circulating and making hole. They suggest that lift off occurs because of the "tight fit" of the body of the bit in the drill hole and the circulation of fluid. They compare the bit with a piston being pushed on by fluid pressure acting on its surface. The BHA weight slacked-off on the diamond bit and which is reflected on the weight indicator is consumed by the contact force of the diamonds on the rock at the bottom of the drill hole and the lift off force. The wear of the diamonds and its penetration rate will depend only on the contact force, and not on the lift off force.

Specialty Pump Parts. Specialty pump parts are compatible with API pumps and are developed by Don-Nan to enhance pumping performance beyond normal API capability resulting in increased operating efficiency, longer run times, and operational cost savings. Sand Diverter The Sand Diverter is a uniquely designed internal pump component used to connect the valve rod or hollow valve rod to the plunger. The standard design for a plunger adapter has an undersized outside diameter and flat top edge that collects sand, shortens plunger life, and increases well service costs. The Sand Diverter is machined from a single piece of extra durable Monel and has an OD face that is nickel spray coated for increased wear resistance and smooth operation.

Artificial lift technologies are wide and varied. The term artificial lift applies to numerous tools, equipment, controls, instruments, computer hardware and software, technologies and techniques used to increase the flow of liquids usually crude oil, water or a mix of oil and water along with natural gas from a production well. Electric energy is often the most significant cost component in the production of oil and gas.
