Underbalanced Drilling (UBD)
Lesson 10 Flow Drilling ,Mudcap ,Drilling Snub Drilling ,Closed Systems
Flow Drilling
 Flow drilling refers to drilling operations in which the well is allowed to flow to surface while drilling.
 All UBD operations are really flow drilling operations, but the term is usually applied to drilling with a single phase mud, and no gas is injected except by the formation.
Drilling Fluid Selection
 Density is determined by:
• Maximum pressure ≤ to formation press ....etc

Oil and natural gas furnish about three-fourths of our energy needs, fueling our homes, work places, factories and transportation systems. Using variety of methods, on land and at sea, small crews of specialized workers search for geologic formations that are likely to contain oil and gas. Seismic prospecting - a technique based on measuring the time it takes sound waves to travel through underground formations and return to surface-has revolutionized oil and gas exploration.

After finding the presence of oil beneath the ground, the most imp ....etc

OIL WELL DRILLING
INTRODUCTION
The purpose of a drill rig is to drill a hole in the
ground. The hole’s purpose is to tap an oil and
gas reservoir. Rigs operate both on land and sea –
“offshore”. Drilling rigs are large and noisy. It has
many pieces of equipments and most of it is huge.

Abstract
Drilling assisted by axial vibration at low frequency is a promising machining process because, by naturally fragmenting chips, it can improve both productivity by canceling stripping operations and work piece quality by decreasing negative effects due to chip friction. Based on a theory of self-excited vibrations, a drilling device has been developed which is described in this paper. This technology is very compact and can used on any conventional machine tool. However the experiments on these machine tools are quite difficul ....etc

It is a heavy duty, direct current, 4 poles and separately excited machine provided with interpoles.The motor with a fabricated magnet frame and rugged mounting feet is used for driving draw works, rotary and mud pump drives. Top mounted, 7.5 HP flame proof AC motor driven blower unit provides necessary cooling air to the main motor and also pressurizes its enclosures including the terminal box for making the drilling motor suitable for operation in hazardous areas. Since drilling motors do not have their own cooling arrangement that is why t ....etc
