In the past six months, the Houston-based company spent $ 76 million to acquire four companies in the so-called premium tubing artificial lift business, that is, makers of pumping units.

During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore, combined with artificial lift techniques ( such as pumps ) which bring the oil to the surface.

In 2001 Dover Corporation formed a segment within the company called Dover Energy, focused on providing products and solutions that serve the drilling, production and downstream markets, including a presence in artificial lift technologies.

For new fields, models may help development by identifying the number of wells required, the optimal completion of wells, the present and future needs for artificial lift, and the expected production of oil, water and gas.

Other uses for submersible pumps include sewage treatment plants, seawater handling, fire fighting ( since it is flame retardant cable ), water well and deep well drilling, offshore drilling rigs, artificial lifts, mine dewatering, and irrigation systems.
26.
Petroleum engineering requires a good knowledge of many other related disciplines, such as geophysics, petroleum geology, formation evaluation ( well logging ), drilling, economics, reservoir simulation, reservoir engineering, well engineering, artificial lift systems, completions and oil and gas facilities engineering.

The life-cycle cost of these systems is similar to other types of artificial lift when appropriately designed, bearing in mind that they are typically low maintenance, with jet pumps for instance having slightly higher operating ( energy ) costs with substantially lower purchase cost and virtually no repair cost.
28.
In 1962, Dover made two notable acquisitions : Detroit Stamping Company, now DE-STA-CO, specializing in the design and manufacture of clamping, gripping, transferring, and robotic tooling solutions; and Alberta Oil Tool, now part of Dover Artificial Lift . Today, Alberta Oil Tool produces specialty drive rods, Norris tubular fittings, Norriseal control values, and other products.

"' John Crane "'is an American company, now a subsidiary of Smiths Group and provider of engineered products and services including mechanical seals, couplings, hydro-dynamic bearings, seal support systems, filtration systems and artificial lift . The company services customers in the energy services sector including production, transmission and storage, refining, power generation, petrochemical, pulp and paper, and mining industries.
