Drilling Fluids Technology

Introduction

This GLOMACS Drilling Fluids Technology training course gives a clear picture for well control to everybody involved in drilling and workover operations. The drilling fluids help the operator to have a smooth drilling operation safely and this is the way to control all formation pressures and also to lift all cuttings from the well as per section and at the same time keeps the well static and full of geological formation intact till the casing is ran and set in place and secure the particular section of the well. Many of particularities conducting to a very expensive mud or brine is due to necessity to keep the well under control all the time throughout the drilling process but also to minimize the skin / formation damage to avoid production problems during the lifecycle of the well.

Primarily in this Drilling Fluids Technology training course, we are concerned with problems associated with selection of the appropriate drilling fluid to accomplish the demands of the well in a cost-effective way.

This training course will contain in-depth information on the cost impact of the mud and brines for drilling and workovers and the preparation for well testing or completion design in maximizing field production and increasing recoverable reserves by keeping well productivity under optimum conditions based on minimum formation damage.

The Drilling Fluids Technology training course will feature:

• All types of drilling Fluids which actually are the blood of all drilling and workover operations.
• Identify and closely predict the cost of mud per well according to the drilling design which can account over 20% of the total drilling cost per well.
• Respect the stiff environment regulations
• Increase the use of advanced wells, highly deviated or horizontal ones by using the proper water base mud and or oil base mud.

Objectives

By the end of this Drilling Fluids Technology training course, delegates will learn:

• To control efficiently the subsurface pressure.
• To keep the holes clean by applying good oilfield operation practice and transporting drastically the drilling cuttings on surface.
• To stabilize and support the borehole.
• To help the designed BHA for drilling to have the best results in minimum time.
• To face drilling problems related to difficult formations where partial or total mud losses occur during circulation.
• To prepare the well for open hole logging.
• To understand the formation damage and to keep it minimum.
• To facilitate the operation to unstuck D/P or during the fishing operations
• To know what are the actions to kill the well in a critical situation.
• To evaluate the efficiency of the drilling fluid according to the formation under drilling and make adjustments and corrections in properties of the fluid.
• To be familiar with FIT and LOT tests during the drilling operations
• Operate new innovative down hole tools like MWD and LWD, DHM and turbines.

Training Methodology

This “Drilling Fluids Technology” training course will be presented using properly designed materials, some and animation on relevant issues. A manual containing all the slides and/or electronic form in PDF will be delivered to each attendant. Teaching methods include several examples of well drilling programs using different drilling fluids. Pre & Post Course Assessments are integrated in this course.

Organisational Impact

The organization will gain, in sending their employees to attend this Drilling Fluids Technology training course, the following:

• Reduction in the cost of the well by proper selection of drilling fluids and / or brines.
• Reducing the cost of the rig and drilling time.
• Ensuring the well integrity and avoiding all risks during drilling and workovers of wells by selection the right fluids.

Personal Impact

• Obtain good knowledge of drilling fluids applications in conventional and non conventional drilling (under balance)
• Improve safety
• Reduce stuck pipe problems
• Familiar with clean fluids for completion
