Downhole |
Term used to describe the equipment and activity found below the wellhead |
|
|
wellflow |
term used to describe the fluid movement of any well from the reservoir to the header system on the platform |
|
|
Reservoir |
A subsurface body of rock having sufficient porosity and permeability to store and transmit fluids under pressure |
|
|
permeability |
the ability, or measurement of a rock's ability, to transmit fluids, or allow fluid movement within a reservoir |
|
|
permeable rock |
the layers of rock within the earth's crust that is made of pours materials, such as sand, that allows gasses and fluids to seep or move within the layer |
|
|
Impermeable rock |
the layers of rock within the earth's crust that is made of solid materials, and prevents the movement of gas and fluid trapped below. An example of non permeable layers could be granite or shale. |
|
|
Downhole |
Term used to describe the equipment and activity found below the wellhead |
|
|
Perforating Guns |
a device used to perforate the production casing of oil and gas wells in preparation for production. These can be the bullet perforating type or the Jet Perforating type. |
|
|
Conductor Pipe |
The shallowest of Casing Pipe. Also called the drive Pipe. The casing string that is usually put into the well first, particularly on land wells, to prevent thesis of the hole from caving into the wellbore. |
|
|
Surface Casing |
A large- diameter, shallow, and relatively low- pressure pipe string set in shallow formation for several reasons. This outermost casing provides structural strength so that the remaining casing strings may be suspended at the top and inside to the formation. |
|
|
Intermediate Casing |
A length of pipe used inside the outermost casing string, to help isolate one or more reservoir as the well is drilled deep and deeper. These inner casing generally rated for higher pressures. |
|
|
Production Casing |
A Casing string that is drilled and set all the way to the desired reservoir depth. |
|
|
Production Tubing |
Holes intentionally created in the production tubing at the reservoir, by using bullet or Jet Perforating equipment, in order to allow formation fluids to enter the production tubing through the production surrounding casing. |
|
|
Perforations |
Holes intentionally created in the production tubing at the reservoir, by using bullet or Jet Perforating equipment, in order to allow formation fluids to enter the production tubing through the production surrounding casing. |
|
|
Perforating Guns |
A device used to perforate the production casing of oil and gas wells in preparation for production. These can be the Bullet Perforating type or the Jet Perforating type. |
|
|
Wellhead |
The collection of spools, valves, and assorted adapters that provide pressure control of a production well. The wellhead may be found on a land well, on an offshore production platform, or on the floor of the ocean for deep water installations. |
|
|
Christmas Tree |
A term used, particularly by drilling personnel, to describe the collection of spools, valves and assorted adapters that make up the wellhead |
|
|
Manual Master Valve |
A valve on the wellhead operated manually by turning a handle that controls all flow from the welfare on a surface well. This valve is usually the first, or lowest valve found on a wellhead. |
|
|
Surface Safety Valve (SSV) |
A required automatically operated valve operated valve located on the upright (Master) or the horizontal part (wing) of a wellhead that will shut off the flow of a well during an abnormal event or when activated by the safety system. These valves must follow the manually operated valves in the master or wing position of a wellhead. |
|
|
Flow T |
Installed on the wellhead, diverts the well flow stream from single or multiple completion wells into their respective floweriness, for testing and measurement prior to entering the platform;s main separators. |
|
|
Manual Wing Valve |
Usually the first horizontal valve found on a wellhead. This valve had a handle, like the Manual Master Valve, that can only be operated manually by Production Operators. |
|
|
Wing Shutdown Valve (SDV) |
An automatically operated valve found on the ' Wing ' or horizontal section of a surface well. A shutdown valve is NOT required on a wellhead, and is often in position because the second SSV on a wellhead has been downrated by the well's MAWP and it SITP |
|
|
Choke |
A device installed on a wellhead that is used to control the fluid flow rate of a well to downstream production equipment. This device can be "Positive" or " Adjustable". A "positive" choke must be removed and a different choke installed in order to change the well flow rate. |
|
|
Flowrate |
Tubular piping that delivers the well flow from the wellhead to the "Header" or "Manifold" on a production facility. |
|
|
Flow Safety Valve |
Required piece of safety equipment that minimized back flow in a well Flow line in the event of a sudden ruptue of the Flowline or other upstream equipment. |
|
|
Manifold or Header |
A system of valves installed in the well flow piping, so that an individual well may be routed to a number of different production equipment, as needed. |
|
|
Shut in Tubing Pressure (SITP) |
The maximum tubing pressure buildup in a shut in well after an extended period of time |
|
|
Maximum Allowed Working Pressure (MAWP) |
Highest operating pressure allowable at any point in any component other than a pipeline during normal operation or static conditions |
|
|
Maximum Allowed Operating Pressure (MAOP) |
Hightest operating pressure allowable at any point in a pipeline system during normal flow static condition |
|
|
API RP 14-C 7th ed March 2001 |
Recommended practice for Analysis, Design, Installation, and Testing of Basic Surface Safety System for Offshore production Plaform |
|
|
hydrocarbons |
Liquid compounds such as propanes, butanes, methane gasses and heavier products extracted from the gas flow stream. |
|
|
Sub- Surface Safety Device |
Down hole safety valve that is installed 100 feet or more below the ocean floor in order to stop the well flow of the well in case of an emergency on the production facility |
|
|
Surface Controlled Subsurface Safety Valve |
Down hole valve assembly that is installed with the tubing string by the drilling rig personnel. The control system operates in a fail-safe mode, with hydraulic control pressure used to hold open a ball or flapper assembly that will close if the control pressure is lost. This valve may be opened or closed by the production personnel. |
|
|
Subsurface Controlled Subsurface Safety Valve |
Wireline retrievable, whereby the principal safety-valve components can be run and retrieved by a wireline operator. The valve is actuated by the flow characteristics of the well, usually a sudden change in the floret. Production personnel have no way to open or close this equipment when desired |
|
|
Control Line |
A small-diameter hydraulic line used to operate downhole equipment such as the surface controlled subsurface safety valve (scssv) |
|
|
Sleeve |
A sliding device in a SSSV that can be operated to provide a well flow path above and below the SCSSV. The sleeve can be operated from the surface by a Production Operator or Wireline Operator when necessary |
|
|
Ball Valve |
(old technology ball valve located within an SCSSV that is rotated to stop well flow in the during an undesirable event r emergency. Modern valves use a flapper valve system. |
|
|
Flapper Valve |
A flapper check valve within a SCSSV that has a spring- loaded plate. The plate is operated either manually by the operator or automatically by the safety system to stop well flow in the event of an undesirable event or system r emergency,. |
