RESERVOIR APPLICATION FLUIDS
Chapter 6
This chapter describes the categories of fluids that are used during and after the productive interval is
drilled. All of the fluids discussed are designed to maximize well productivity.
INTRODUCTION
Reservoir application fluids are any fluids to which the reservoir will be exposed during drilling,
completion and workover operation. These fluids are designed to maximize hydrocarbon
production from the production interval(s). This is achieved by minimizing formation damage
during drilling and completion operations and maximizing the production potential of the
completion methodology. It is first necessary to gain an understanding of hydrocarbon reservoirs
before examining their interactions with drilling, completion and workover fluids.
A more thorough understanding of the purpose and application of these fluids requires some
knowledge of the earth’s geology and of formations from which petroleum products are
commercially produced.
PETROLEUM GEOLOGY
Geology is the science of the earth, its origin and development through the past, its size, shape and
composition, the processes that are now, or have been at work on its surface, and its interior; also its
life forms since its origin. Geology as a science has its own techniques of geological mapping and
for reconstruction of past events. It also uses other sciences, such as chemistry, biology, physics and
engineering methods and theories.
Geology has the following branches:
• Crystallography
• Mineralogy
• Petrology
• Geochemistry
• Structural Geology
• Geophysics
• Stratigraphy
• Sedimentology
• Paleontology
• Geomorphology
