Considerations for Using a Hydraulic Fracturing Fluid for Breaking Crude Oil Emulsion from Reservoir

Abstract

In the oil industry, crude oil emulsions appear very frequently in almost all activities, starting with drilling and continuing with completion, production, transportation and processing. They are usually formed naturally or during oil production and their presence can have a strong impact on oil production and facilities. In this paper we addressed the problem of oil emulsions present in a reservoir with unfavorable flow properties. It is known that the presence of emulsions in a reservoir can influence both flow capacity and the quality of its crude oil, especially when they are associated with porous medium�s low values of permeability. Considering this, we have introduced a new procedure for selecting a special fluid of fracture. This fluid has two main roles: to create new flow paths from the reservoir rock to wells; to produce emulsion breaking of emulsified oil from pore of rocks. Best fracturing fluid performance was determined by laboratory tests. Selected fluid was then used to stimulate an oil well located on an oil field from Romania. In the final section of this paper,we are presenting a short analysis of the efficiency of the operation of hydraulic fracturing stimulation probe associated with the crude oil emulsion breaking process.

Estimation of the Combustion Temperature Profile in a Romanian Oil Field

“…one trillion cubic meters) or more than two-thirds of the world's oil resources, are heavy and viscous crude oil. Huge heavy oil resources of the world represent an important global energy supplier, but require a high level of effort and expertise to economically developed and produced, and is a challenge for production and refining [2]. Many countries tend to increase their oil production, revising their estimated resources, testing new technologies and investing in infrastructure in order to ensure optimal production of heavy oil resources.…”
