Oil & Gas Controls &
Instrumentation Service — Mid-South

The Mid-South is crisscrossed by major interstate pipeline infrastructure moving Gulf Coast production to national markets. Alabama and Mississippi have active onshore production in the Black Warrior and Interior Salt basins. Louisiana is one of the nation's top oil and gas producing states. The region also supports significant offshore Gulf of Mexico operations through onshore infrastructure in southern Louisiana and coastal Alabama. Memphis Control Center has been supporting Mid-South industrial facilities — including oil and gas operations — since 1967.

Oil & Gas Infrastructure Across the Mid-South

From onshore production fields in Alabama and Mississippi to the Gulf of Mexico offshore support infrastructure along the Louisiana and Alabama coasts, the Mid-South is home to significant oil and gas activity and the pipeline corridor that moves it to market.

Major interstate pipeline systems pass through or originate in the Mid-South. Kinder Morgan operates the Tennessee Gas Pipeline running through Arkansas, Mississippi, Tennessee, and Alabama, and the Southern Natural Gas system — approximately 6,900 miles of pipeline extending from supply basins in Louisiana, Mississippi, and Alabama. Gulf South Pipeline (Boardwalk Pipeline Partners) operates a 7,260-mile system through Louisiana, Mississippi, and Alabama. The Energy Transfer Mid-Valley crude oil pipeline runs through Louisiana, Arkansas, Mississippi, and Tennessee. These systems have compressor stations, metering facilities, and control infrastructure throughout our service territory.

Alabama has onshore oil and gas production in the Interior Salt Basin and the Black Warrior Basin, which extends into northern Mississippi. Louisiana is consistently ranked among the top oil and gas producing states nationally, with both active onshore production and extensive offshore Gulf of Mexico support infrastructure. Memphis Control Center supplies instrumentation, controls, and industrial electrical components to these operations from our Memphis headquarters.

Note: This table is a general reference. Specific regulatory requirements for your facility depend on your commodities, throughput, permit conditions, and applicable state and federal requirements. Always coordinate controls and instrumentation work with your facility’s operations, safety, and regulatory teams. Memphis Control Center supports the parts and service coordination side — we are not oil and gas regulatory consultants.

Common Oil & Gas Controls Problems

The most common controls and instrumentation issues we support in oil and gas production, pipeline, and processing facilities.

Controls Troubleshooting — Oil & Gas Facilities

Reference for instrumentation and controls technicians. Always follow your facility’s permit-to-work, hot work, and gas testing procedures. Work in classified areas requires appropriate precautions and properly rated equipment.

Pressure transmitter reading erratically at pipeline SCADA
Erratic pipeline pressure transmitter readings are most commonly caused by impulse line issues — liquid accumulation in gas service, gas pockets in liquid service, plugging with hydrates (common in natural gas service), or loose/corroded connections. Isolate the transmitter and check zero: does it read correctly with equalized pressure? If yes, the problem is in the impulse lines — check for hydrate plugging, drain condensate, or heat-trace the lines if hydrate formation is recurring. If the transmitter still reads incorrectly with equalized pressure, check the electronic module and verify the configuration matches the expected range. In H₂S service, also verify the process isolating diaphragm hasn’t been attacked by the process fluid.
Pressure transmitters for natural gas and crude oil service available in appropriate pressure ranges — call with your process conditions.
Compressor station ESD triggered — unit offline
A compressor station ESD trip requires identifying the initiating condition before restart per the station’s operating procedure. Check the ESD first-out indication: was it a high-pressure trip (check downstream pressure), low suction pressure trip, high vibration trip (check for mechanical issues), high-temperature trip (check cooling system), or a manual trip? Do not attempt to restart without correcting the initiating condition. For high-vibration trips, have the compressor unit inspected before restart — a vibration trip can indicate developing bearing or mechanical issues that will worsen on restart. Document the trip cause and time per your operating procedure.
ESD solenoid valves, pressure transmitters, and temperature sensors for compressor stations — call with your equipment specs.
Fired heater BMS lockout — process outlet temperature dropping
A fired heater BMS lockout in a gas processing or pipeline terminal facility requires identifying the trip condition before relighting. Check: was it a flame failure (flame safeguard relay lost flame signal), a fuel gas low pressure trip, a high process temperature trip, or a loss of draft? For flame failures, check the scanner for fouling — process heaters in oil and gas environments can get condensate or particulate on optical scanner windows. Check the pilot gas supply before attempting re-ignition. Do NOT re-ignite without completing the required pre-purge to clear any accumulated fuel gas from the firebox. The purge cycle is required by NFPA 85 regardless of how quickly you want to restore heat to the process.
Flame safeguard relays, scanner systems, and fuel gas controls for process heaters — call with your heater type and BMS model.
H₂S gas detector alarming — uncertain if real or false alarm
Never assume an H₂S detector alarm is a false alarm without verification — H₂S is immediately dangerous to life and health at relatively low concentrations (NIOSH IDLH: 50 ppm; OSHA PEL: 20 ppm ceiling). Follow your facility’s alarm response procedure first. If the area is safe to approach with proper PPE, check the detector: has it been calibrated recently? Is it past its sensor replacement interval? Cross-check against other detectors in the area. For electrochemical H₂S sensors, note that low-humidity environments and high CO concentrations can cause cross-sensitivity issues. Bump-test the detector with known concentration gas to verify response. Detectors that fail bump test must be replaced — do not leave an H₂S detector in service that won’t respond to calibration gas.
H₂S detector sensors, calibration gas, and replacement heads available — call with your detector make and model.
Control valve not maintaining pipeline pressure setpoint
A control valve failing to maintain pressure setpoint on a pipeline system is a significant operational issue. Check first: is the valve actually moving to where the positioner is commanding it? Measure valve position with a calibrated position indicator if available. If the valve is fully open and pressure is still below setpoint, the issue may be upstream supply (demand exceeds capacity) rather than a valve problem. If the valve is not responding to the controller output, check the positioner — is it receiving the correct 4-20mA signal from the controller? Is instrument air supply adequate? Check I/P transducer output with a gauge at the positioner. Sticky valves from hydrate or wax deposits are also common in natural gas and crude service — check valve operation through its full range.
Control valve positioners, I/P transducers, and solenoid valves for pipeline service — call with make, model, and pressure class.
IS barrier showing open circuit in classified area instrument loop
An open circuit indication on a Zener IS barrier means the barrier’s fusing element has opened — this is a protective safety function. Verify the field wiring and device are not shorted (which would have blown the barrier). If the field device and wiring check out, replace the barrier with an identical model — the input/output parameters must match exactly to maintain IS certification. Before working in the classified area, verify gas-free conditions per your facility’s hot work and gas testing procedure. Never replace a Zener IS barrier with a standard non-IS isolator in a Division 1 application. Consider whether galvanically isolated IS barriers would better suit your application (galvanic isolators are less sensitive to loop resistance and don’t require a grounded instrument cabinet).
IS Zener barriers and galvanic isolators for oil and gas classified area applications — call with barrier model for verified replacement.

Frequently Asked Questions

What pipeline systems run through the Mid-South?
The Mid-South is a significant pipeline corridor. Major natural gas pipeline systems include the Kinder Morgan Tennessee Gas Pipeline (running through Arkansas, Mississippi, Tennessee, and Alabama), Southern Natural Gas (approximately 6,900 miles from Louisiana, Mississippi, and Alabama supply basins to southeastern markets), and Gulf South Pipeline (7,260 miles through Louisiana, Mississippi, and Alabama). On the crude oil side, the Energy Transfer Mid-Valley pipeline system runs through Louisiana, Arkansas, Mississippi, and Tennessee. These systems have compressor stations, metering facilities, and control infrastructure located throughout our service territory — all requiring ongoing controls and instrumentation service and maintenance.
What oil and gas production areas are in the Mid-South?
The region has several active oil and gas production areas. Alabama has onshore oil and gas production in two main sedimentary basins: the Interior Salt Basin in southwestern Alabama and the Black Warrior Basin in northwestern Alabama. The Black Warrior Basin extends westward into northern Mississippi. Alabama is among the top 20 oil producing states and has been a significant natural gas producer, with the Lower Mobile Bay–Mary Ann Field having been one of the largest natural gas discoveries east of the Mississippi River. Louisiana is consistently one of the top five oil and gas producing states nationally, with both active onshore production and offshore Gulf of Mexico operations. Arkansas has significant oil production history in the Smackover and El Dorado areas of southern Arkansas — El Dorado was home to the Arkansas oil boom of the 1920s and remains an active refining and petrochemical hub, along with natural gas from the Fayetteville Shale in north-central Arkansas.
What is the H₂S hazard IDLH threshold and why does it matter for instrumentation work?
NIOSH establishes the Immediately Dangerous to Life or Health (IDLH) concentration for H₂S at 50 ppm. OSHA’s permissible exposure limit (PEL) is 20 ppm as a ceiling value. H₂S is particularly dangerous because it paralyzes the olfactory nerve at concentrations above approximately 100-150 ppm — meaning that at dangerous concentrations, you can no longer smell it. This matters for instrumentation work in oil and gas facilities because entering areas where H₂S may be present requires gas monitoring with a calibrated personal H₂S monitor, understanding of detector alarm levels (typically 5 ppm warning, 10 ppm evacuation for many facilities), and compliance with your facility’s H₂S safety plan. Gas detectors used for H₂S monitoring must be calibrated regularly and bump-tested before each use. Detectors that fail bump testing must be replaced before use in H₂S service areas.
What is 49 CFR Part 192 and how does it affect pipeline instrumentation?
49 CFR Part 192, administered by DOT’s Pipeline and Hazardous Materials Safety Administration (PHMSA), covers the transportation of natural and other gas by pipeline. For instrumentation and controls, Part 192 affects several areas: control room management (Subpart M) requires that instrumentation supporting pipeline control room operations maintain defined performance and be calibrated on a documented schedule; corrosion control requirements specify that cathodic protection instrumentation be monitored and recorded; and integrity management provisions require that instrumentation supporting inline inspection and pressure testing be accurate and maintained. Gas pipeline operators are required to maintain records of instrumentation calibration and maintenance as part of their overall pipeline safety management systems.
Do you supply equipment rated for Class I Division 1 and Division 2 oil and gas locations?
Yes — we can help specify and supply instrumentation and control components rated for hazardous locations per NEC Article 500. Class I Division 1 locations (where flammable gases or vapors are likely under normal operating conditions) require explosion-proof or intrinsically safe equipment. Division 2 locations (where flammable atmospheres are not likely under normal conditions but may occur abnormally) allow additional equipment types under specific conditions. Oil and gas production, processing, and pipeline facilities typically have Class I areas throughout — Group D (natural gas, propane) and Group C (hydrogen sulfide, ethylene) are the most common classifications in Mid-South oil and gas facilities — with H₂S a particular concern in sour gas production and processing environments. Call us with your area classification and application and we’ll specify the right rated equipment.
Can you help with parts for a compressor station or pipeline facility outage?
Yes — we can help stage common instrumentation, controls, and electrical components for planned compressor station or pipeline facility outages. Common outage items include pressure and temperature transmitters, control valve positioners and I/P transducers, ESD solenoid valves, IS barriers and galvanic isolators, and PLC/RTU spare components. For emergency situations — an unplanned compressor station or pipeline facility shutdown — call us at (901) 458-2000. Many common components ship same day from Memphis by 2 PM CT.
