In this study, a mathematical model is developed to predict the efficiency of a down-hole oil–
water separation hydrocyclone. In the proposed model, the separation efficiency is …

Selection of the most economical artificial lift method is necessary for the operator to realize
the maximum potential from developing any oil or gas field. Historically the methods used to …

Frequently oil is produced while, simultaneously, large amounts of water are produced as
well. Under these circumstances it is important to have compact and efficient deoiling …

Downhole water sink (DWS) technology controls bottomwater coning by draining water with
a second completion placed under the oil-water contact. The technology has been studied …

At present, many oil fields in China have entered the high‐water‐cut production period, and
the water cut of oil wells has continued to rise. Therefore, how to reduce the water cut of the …

This paper is a follow-on to SPE 28694 which summarizes and categorizes ESP literature by
a number of different topics. The intent is to list problems mentioned in various papers and a …

The chapter presents development of Environmental Control Technology (ECT) for oilfield
drilling and production processes using the ECT methods of source reduction, source …

The Thesis is an analytical and numerical analysis of a new method for completing and
producing oil wells affected by water coning. The method enables producing oil with no or …

There are numerous water shut-off techniques available. One of these is to permanently seal
watered-out zones with rigid, polymer gelants. This method can be very effective for near …

Although water coning is well understood, it is difficult to control in field operations resulting
in low recovery and large volumes of waste produced water. A solution-proposed here-is a …
