​Decoding Oil and Gas Jargon

Back to Blogs

In this blog we will be unearthing terms that might sound foreign to the average person’s day to day conversation but hold significant importance in the Oil and Gas industry. How many of these terms do you recognise before diving into their definitions? Let's dive in and demystify the terminology.


In the context of the Oil and Gas sector, "abandonment" refers to wells. An abandoned well is one that is no longer in use, either due to being dry, non-functional, or unproductive.

Blow-out Preventers

Picture a colossal valve atop a well that can be sealed shut if the drilling crew loses control over the fluids within the formation. This mighty valve, often operated remotely through hydraulic mechanisms, is what's known as a blow-out preventer or BOP. These come in diverse styles, sizes, and pressure ratings.


A Derrick may sound like a convoluted piece of jargon, but it's essentially a structure strategically positioned to provide enhanced support for the crown blocks and drill string of a drilling rig. Typically pyramid-shaped, derricks offer impressive strength-to-weight ratios. Skilled ironworkers are sometimes called upon to meticulously assemble derricks, piece by piece. And when the time comes to relocate, they'll meticulously disassemble it as well.

E&P (Exploration and Production)

E&P, often referred to as Exploration and Production or Upstream operations, relates to equipment, systems, or facilities located within the wellbore or the production train, occurring before the "surface choke" or Christmas tree—yes, those are valves sets.

GTL (Gas-to-Liquids)

GTL isn't just a random arrangement of letters. It stands for Gas-to-Liquids, a refinery process that revolves around the transformation of natural gas or other gaseous hydrocarbons into longer-chain hydrocarbons, including diesel fuel and gasoline.

Liquefied Natural Gas (LNG)

Liquefied Natural Gas, often comprising methane and/or ethane, represents natural gas that has undergone a transformative process, converting it into liquid form through cryogenic temperatures. This procedure proves particularly valuable when the need arises to transport gas from remote offshore or jungle regions where conventional pipelines are not feasible.


Within the realm of Oil and Gas, a roughneck is the vital cog in the wheel of an oil rig. Operating on most drilling rigs, roughnecks shoulder the responsibility of upkeeping and mending equipment stationed on the drill floor and the imposing derrick structure.


In the Oil and Gas domain, a toolpusher assumes the mantle of a location supervisor. This senior and seasoned team member typically ascends the ranks through various drilling crew roles. Their duties lean heavily towards administration, encompassing material and part inventory management, and even personnel oversight. Often esteemed as an information hub for on-site peers, the toolpusher is a potential wellspring of advice and guidance.


Waterflooding constitutes a technique harnessing water injection to augment oil production from reservoirs. This process, tantamount to a strategic boost to oil extraction, is commonly recognised as Secondary Recovery.


In the intricate tapestry of drilling, a wellhead takes the form of an assemblage comprising spools, valves, and an array of adapters that collectively orchestrate pressure control for a production well. In the realm of well completions, the wellhead emerges as the surface zenith of a wellbore. This multifunctional entity encompasses the provisions for installing casing hangers during the well's construction phase.

And there you have it—a number of pivotal Oil and Gas terms, expertly deciphered. Mastery of these terms is certainly a valuable asset as you tread into this industry's fascinating landscape.
