Nuclear Regulatory Commission (NRC). A specialized crew transports and operates the perforating equipment. Upon arrival to the site, the tools are assembled, then lowered into the well by a wireline unit or conveyed by tubing. Then, a specialized gun shoots small holes into the casing of the producing zone.

The perforations allow the oil or gas to flow into the casing or liner. If pressure is sufficient, the oil or gas will rise to the surface. Detailed operational procedures and trained personnel are necessary for the safe handling of explosives. The solutions below illustrate possible solutions; for more detailed information see Additional Information below.

Swabbing is the act of pulling fluid from the well bore through the use of wire rope and cup assembly. Swabbing equipment includes a swabbing assembly, lubricator with an oil saver, and shut-off valve on the well, also called a swabbing valve. General precautions during all swabbing operations:.

Conduct swabbing operations during daylight hours. Keep all personnel clear of the derrick or within six feet (two meters) of the wellhead during swabbing operations. Locate swab tanks at least 100 feet (30 meters) from the well, where location allows.

Potential Hazard:. Loss of well control. Possible Solutions:. Use appropriate equipment, rated for the expected pressures, to shut in the well. Inspect lubricators, swages, and unions for defects such as cuts, corrosion, and thread damage before use. Adjust oil savers by remote control with a hydraulic pump placed safely away from the wellhead. Train all personnel in emergency evacuation procedures.

Potential Hazard:. Fire, explosive, or respiratory hazard from leakage or venting of oil or gas from tanks, lines or lubricator. Possible Solutions:. Place fire extinguishers in accessible positions. Move sources of potential ignition (such as, open fires for melting of babbitt) to designated areas at a safe distance from the wellhead or flammable liquid storage areas such as the swab tank before swabbing.

Make provisions to contain spilled flammable liquids. Monitor the oil saver for wear and potential leakage. Remove all spillage of flammable liquids from equipment, cellars, rig floor, and ground area adjacent to the wellhead.

Wear proper personal protective equipment, including respiratory protection, as required. Potential Hazard:.

Being struck by a pressurized line. Being exposed to a high-pressure connection failure caused by mismatched or excessively worn hammer unions. Possible Solutions:. Avoid approaching, walking over or standing near pressurized lines.

Securely anchor pressurized lines to prevent whipping or bouncing caused by pressure surges. Use proper equipment inspection techniques to include hammer unions (Note: This is a particular problem with 602 and 1502 and others, as they will couple but will not hold beyond the lower pressure rating number).

Potential Hazard:. Pinching fingers between swab assembly and lubricator when changing swab cups or mandrels. Possible Solutions:.

Use a winch line, where available, not the swab line, to handle the lubricator. Use a lubricator that will allow removal of the swab or other tools with the well shut in (valve closed). Additional Information:. American Petroleum Institute (API). RP 54, Occupational Safety for Oil and Gas Well Drilling and Servicing Operations. (2007, March). Hot oiling truck A hot oil unit is designed to circulate heated fluid into piping, tubing, casing, or tanks for a variety of reasons, including the removal of paraffin and tar-based oils.

Potential Hazard:. Fire or explosion hazard from contact with flammable liquids, vapors, or gases. Possible Solutions:. Locate hot oil trucks and tanks a safe distance (100 feet is recommended) from the well and out of the fall line of the derrick, if it is on site. Where impractical, use additional safety measures. Position hot oil units upwind or crosswind from potential sources of flammable liquids, vapors, or gasses.

Wind direction indicator should be present and visible to the operator. Shut down hot oiling operation immediately if a leak occurs. Make fire extinguishers readily accessible to the hot oil operator. Avoid parking over or placing lines containing flammable fluids under trucks or other vehicles. Install check valve in the pump line as close to the well head as possible. Inspect all components of the hot oil unit before each use.

Shut the burner down if the wind dies. Shut the burner down and reposition equipment if the wind changes direction so as to create a hazard. Potential Hazard:. Being burned by hot oil or hot oil line or frostbite injuries from contact with propane or propane lines. Possible Solution:. Wear appropriate personnel protective equipment such as heavy padded, insulated, leather gloves.

Potential Hazards: Expert Review. Unexpected release of pressure. Possible Solutions:.

Do not connect heavy joints of pipe to the small nipples on the pumping T. Secure all hot oil and discharge lines. Connect the hot oil line directly to the flow line if pump pressure exceeds safe limits (500 psi). Remain clear of pressurized lines. Snubbing is the control of a tubing string while running it in or out of a well bore under pressure. Note: The special service supervisor should hold a pre-job meeting with the special service crew and other involved personnel to review responsibilities and to coordinate the operations to be performed.

Potential Hazards:. Pinching fingers and hands.

Being exposed to an unexpected release of pressure. Getting struck by falling or shifting objects (such as suspended injector heads). Falling from heights. Possible Solutions:.

Keep all fingers and hands away from pinch points (such as tubing spool, rollers, injector head). Inspect the tools and equipment before use.
