Decoding 3 Types of Gas Lift Systems in Oilfield Services

The management of oilfields involves different processes. These processes require different types of tools such as cement retainers, sand management products, completion accessories, and more. One of the top requirements in oilfield management is a gas lift system. This system helps to enhance bottom hole pressure in the reservoir so that more oil rises to the surface. This mechanism helps increase oil production and boosts the overall efficiency level. There are different kinds of gas lift systems available in the oilfield services sector. This blog decodes the meaning and use of the three main types.

Core Components of a Gas Lift System

A gas lift system is a complex setup consisting of several components. It is a form of an artificial lift system. However, it has three core components that are crucial to identify and understand. These are:

●       Gas Lift Valves: These are valves used within gas lift systems for controlling how fast the lift gas flows into a production tubing system. The valves open in a specific order. Then, they inject gas so that fluid present within the tubing conduit can rush to the surface. The valves need gas lift mandrels for continuous connectivity with the tubing.

●       Gas Lift Mandrels: These are hardware devices installed inside the production tubing string. The assembly of these two components helps in locating the lift valves. At the same time, the mandrel helps connect the valves to the tubing for seamless operation.

●       Production Tubing String: This is the main conduit for helping fluids reach the surface. It uses the support of the valves and mandrels to promote oil production in a well.

Three Types of Gas Lift Valves and Mandrels

While sourcing your gas lift system from an oilfield services company, you can choose between the following types.

●       Conventional: Conventional systems have the valves attached to the exterior portion of the mandrels. Workers insert this set inside the production tubing string in a sequence. The assembled set of these components goes into the well together. This system works very efficiently. However, maintenance work necessitates the withdrawal of the whole assembled set. This variant is suitable for oil wells having continuous flow.

●       Retrievable: Retrievable gas lift and valves are excellent for wells with intermittent flow. Here, the mandrels have inbuilt pocket receivers. This feature allows the workers to insert gas valves as necessary and remove them for maintenance. These retrievable systems use orienting devices to ensure efficient operation within the oil well.

●       Water Injection: Water injection valves and mandrels are beneficial when the oil well is at risk of water floods. These systems have water-resistant materials, making them capable of withstanding the challenges associated with flooding in the oil field region.

Now that you know about these types, you can choose what you need for your oilfield management.

Applications of Cement Retainers and Bridge Plugs in the Oil & Gas Industry

The reliance on renewable sources is increasing in recent times. However, the demand for oil and gas is still on the rise. To ensure the safe completion of different tasks, the oil and gas industry requires several servicing tools. No doubt,  sand screens  are the most crucial tools used in the sector. However, besides the control screens, the  cement retainers  and  bridge plugs  are also vital. In this blog, you will explore the applications of cement retainers and bridge plugs in the oil and gas industry. Let’s dive in! Cement Retainer A cement retainer is an inflatable service tool that oil and gas companies use for remedial cementing operations. It sets in any casing type securely. The cement retainer helps in squeezing off the unwanted gas channels or production between the casing and the open hole. It allows the pumping of cement and other fluids through the tool. Applications of Cement Retainer Cement Squeeze The cement retainers act as squeeze tools that i

  Oil and gas production is a unique operational process that consists of large-scale industrial applications. However, these applications run on finely calibrated systems offering accurate output and input relays. Due to the volatile nature of such operations, expertise is essential when installing new components like an artificial lift system . Drilled oil wells lie in a nascent, high-pressure state. Thus, when installing completion accessories, you’ll require precision and accuracy. We suggest you let an expert well completion service do the job for you. These services gauge the needs of your well and use adequate completion accessories to finish the job. Conventional Gas Lift Valves As a common artificial lifting accessory, the conventional IPO gas lift valve sits in or on a gas lift mandrel. These accessories inject the liquid or chemicals from your well to help them surface consistently. Due to the nature of this procedure being so delicate, it's essential to set up the s

Sand Management Services for Oilfields: Why are they important in oilfields?

Establishing an oil field is no easy feat. Many processes and services go into refining the end product, and one of them is  sand management services . As the name suggests, sand management is the procedure of controlling or managing sand production into a wellbore. Why? Because sand production can induce several challenges in production impairment. Typically, two fundamental methods are used in oilfields to avoid sand production. Let’s delve into them!   #1 Active Sand Control Fundamentally, the active sand control technique revolves around using filters to control sand production. Also known as the intrusive method, the techniques of active sand control include chemical consolidation, gravel and frack pack, expandable sand screen and standalone screen.   #2 Passive Sand Control Unlike active sand control, passive sand control uses non-intrusive measures for reducing, controlling or sidestepping sand production from the reservoir. The techniques of passive sand control inc
