OIL AND GAS
The need of Oil and Gas production becomes more and more interesting, as the consumption in countries like China, India some other African countries rises constantly, but also Western Europe, USA and Russia consume significant more Energy than 15 or 20 years ago. The worldwide Oil reservoirs are massive, however, we need to keep in mind, that with the technology we currently have we need to leave approx. 50% down in the ground. To keep up with the constant growing consumption of Oil and Gas, the development of new field becomes necessary, however, old and marginal fields need to be upgraded and modified to earn the maximum out of it.
The early Oil production about 100 years ago started always with light oil, it just came out of the ground when they drilled the deep wells, that’s what we are used to when we look at old photos which show a “Blow Out???. To find new oil reservoirs with light oil now is quite seldom, most of new developed Oil fields produce heavy oil. The production of heavy oil is more elaborate, and it is mostly lower than on light oil fields. Many additional equipment has to be installed to get a satisfying production rate. The technologies like e.g. polymer- water- or steam-injection, gas lifting or artificial lift due to adding down-hole pumps at the well, and multi-phase pumps on the surface, require really tough pump designs, which need to cover a wide range of temperature and pressure, as well as chemical resistance.
Since the mid 80’ the Oil Industry uses Progressive Cavity Pumps for several different kind of services. The unique feature of Progressive Cavity Pumps, just like, gentle handling at Oil/Water Separation, constant flow at various pressures and viscosities, low NPSHr. These pumps are very forgiving vs sand and other none welcome particles, ability to handle gas, makes this kind of pumps essential at many stages of the production of Oil & Gas.
The general guideline for the design of these pumps is the API 676, 3rd edition, which covers rotating positive displacement pumps, the Category Progressive Cavity Pumps belong to.
