The Anatomy of a Wireline JOB Wireline executes jobs in all places, from Alaska to Australia. Naturally, the operating conditions and way the jobs are executed and prepared are all different. However a Wireline Job generally consists of 3 main elements or Phases: Lets summarise the 3 phases 1

Job Execution

POST-JOB tasks

The Pre-job is arguably the most critical phase of the operation.

This is the part when we go to the clients well and carry out the operation that has been requested.

This is after coming back from the job to the base.

™Plans are put in place to ensure that all conceivable problems and issues are anticipated and addressed. ™It is the time to get yourself technically trained and ready to deliver to the clients expectations. ™Most of the problems at the well-site are linked to Poor Prejob planning.

WLH-JDA-PRE-SCHOOL

June 06

™Here, it is critical to carry out the job efficiently and to the clients expectations (and hopefully to exceed expectations) ™This is also where safety is a critical concern. You will be responsible for the safety of your crews and the client personnel involved in your operations. ™Here, you must deliver technically the service that you have promised to the client. ™You are the FACE of Schlumberger during this phase

™Here the equipment is serviced and checked to make sure that it is fit for future operations. ™Equipment or tools that have failed or have been damaged must be reported and their maintenance must be followed up. ™The data or materials that need to go to the client are usually prepared and delivered (this may have been done at the well site.

PRE-JOB preparation

™Here the tools and equipment are prepared, checked, calibrated and serviced.

PRE-JOB Preparation This phase is considered the most important in terms of delivering the superior service quality that our clients expect from us. 1

PRE-JOB preparation Checklist

This is a PRACTICAL task that you will learn by participating fully in the operation. The purpose of this slide is to provide you with a checklist of things to observe.

9What is the procedure for mobilizing a job in the location. Who decides the equipment and people going to a job. 9What is a briefing; who attends it; what is discussed in the briefing. 9What maintenance is done to the tools and equipment. What is a RITE BOARD and how is it used. 9How does the engineer check that the tools are ready for the job. 9How are the tools are transported to the Well-site.

Understanding and participating in these tasks will help you to become familiar with the operations and procedures. Go out there and get involved. 5

JOB Execution-2 LAND RIGS There are many types of Rig facilities around the world depending upon the type of environment. Lets look at some of the possible places you might be going.

Schlumberger Private

A land rig can be found anywhere on the planet. It can be in a jungle or on top of a mountain, in the desert sands or in the middle of city. Wherever the rig is placed, a large area must be cleared to facilitate the operations. 7

JOB Execution-3 OFFSHORE RIGS The offshore open-hole operations are carried out by drilling rigs. If your location is offshore, these places will soon become a second home. The most common types of offshore drilling rigs are the Jack-up and the ‘Semi’ Submersible

Schlumberger Private

The JACK-UP (above and top-left)

Semi-Submersible Also called a ‘Floater’ or a ‘Semi’. This rig can be used in relatively deeper waters. 8

WLH-JDA-PRE-SCHOOL

This rigs stands on threelegs. This is used in relatively shallow waters.

JOB Execution-4 Other OFFSHORE RIGS There are other types of offshore rigs that you might come across.

Artificial Island In really shallow waters an artificial island is created.

Schlumberger Private

How will you get to the office? You will nearly always fly to the rigs on helicopters.

DRILL SHIPS In ultra-Deep waters, Drill-ships like this one are often used 9

22- Choke Manifold 23- Pipe Ramp 24- Pipe Racks 25- Accumulator

JOB Execution-7 People on the Rig-1 No matter what type of rig you go on you will see many of these people working on the rig. A COMPANY MAN is a representative of an oil-drilling company (e.g Shell, BP). Other terms that may be used are Company Representative, Drilling Engineer, or Rig site Leader. He has overall control of the rig-site and authority in all matters. All operational issues should be discussed with the Company Man. He will give you all the information you need about the well and the drilling.

The TOOL PUSHER is the person responsible for all operations on a Drilling Rig. They are also known as rig managers. Tool pushers are in charge of keeping the rig and all necessary tools and equipment, supplies, etc. They work closely in conjunction with the company man in regards to the actual drilling of the well. Tool-pushers also take on an administrative role. Usually a tool pusher has started at the bottom and worked his way up and has been in the industry for a number of years. 12 WLH-JDA-PRE-SCHOOL June 06

Schlumberger Private

The OFFSHORE INSTALLATION MANAGER (OIM) is the most senior member of management on many larger Drilling Rigs particularly large jack-ups and platforms and some semi-submersibles. On smaller rigs the Tool Pusher will usually be the most senior member of management, but will work under the OIM when one is present.

JOB Execution-8 People on the Rig 2 A DRILLER is the supervisor of the Rig Crew The driller operates the pumps, draw-works, and rotary table via the drillers console - a control room of gauges, control levers, rheostats, and other pneumatic, hydraulic and electronic instrumentation. The driller also operates the draw works brake using a long-handled lever. Hence, the driller is sometimes referred to as the person who is "on the brake."

roughneck usually performs semiskilled and unskilled manual labor. They report to the Driller A Roustabout is an Un-skilled laborer that does general duties around the rig. They can be promoted to become Roughnecks. They also report to the driller.

Derrick-man reports directly to the Driller. The name derrick man comes from the position that he normally occupies, which is at the top of the Derrick. From this position, he guides the stands of drill-pipe (typically 90 ft long) into the fingers at the top of the derrick while tripping out of the hole. When tripping into the hole he will pull the pipe out of the fingers and guide it into the top drive or the block. 13 WLH-JDA-PRE-SCHOOL June 06

Roughneck is a low-ranking member of the Drilling crew. A

JOB Execution-9 People on the Rig 3 Mud Engineer’s job is to determine the correct Mud, also called drilling fluid, to use for the well, advising treatment and monitoring its condition. Main properties monitored are density, viscosity, chemical parameters and solids content. If properties divert from mud program mud engineer will notify drilling crew and company man and advise treatment. Normally, you must go see him for a sample of mud and get the Mud report.

A mudlogger tasked with gathering data and collecting samples during the drilling of a well and organizing this information in the form of a graphic log, showing the data charted on a graphic representation of the wellbore. Mudloggers observe and interpret the indicators in the mud returns during the drilling process. The mudlogger logs at regular intervals, properties such as drilling rate, mud weight, flow line temperature, natural gas content and type, oil indicators, pump pressure, pump rate, lithology (rock type) of the drill cuttings, and various other items of interest

Oil companies use geologists' to help them locate oil and Gas deposits. They will look at the Data from the well such as the mud-logs and the Wireline logs and make sure that the geological objectives of the well are met. He may be the witness of the Wireline log. The Geologist will give you the technical information to help you set parameters for the operation.

JOB Execution-10 People on the Rig 4 The Undisputed King or Queen of the Oilfield. He or she is responsible for carrying out a host of complex, technical operations on the rig. Normally, Rig personnel have no idea what the Wireline Engineer does. He or She is usually the youngest, most educated, most highly-paid (and best looking) person on the Rig. For these reasons, the Wireline Engineer is sometimes resented or disliked by people on the rig. He or She always wins people over by showing great respect and professionalism towards all rig-workers at all times on the Rig. Apart from the blue coveralls and PPE, the Wireline Engineer wears a smile and has in his pocket a friendly hand-shake always ready to offer.
