Giving you the full picture of your well’s performance
We are experts in well integrity evaluation. For 30 years we’ve been delivering solutions that help operators overcome their well challenges all over the world.
Well integrity evaluation means getting the full picture of your well’s barrier performance. It’s about understanding the structural integrity of your tubing, casing, liners and cement. Ultimately, this helps you manage risk, extend operating life and optimise the management of your wells across their lifecycle.
READ has a suite of dedicated well integrity technologies for accurately identifying and quantifying damage and deformation, holes, leaks, corrosion and scale build-up, deployable on electric wireline, slickline or coiled tubing in memory and real-time.
Our solutions are tailored to your individual equipment and operations. Our know-how and expertise provide the answers to help with:
Well Integrity Services
By applying best-in-class radial geometry and wall thickness sensor technologies, we document every detail of every completion element. This data creates a robust baseline for operators to measure changes over time. We help you understand the evolution of your well’s integrity, identifying issues in advance of failure and knowing exactly where and when to intervene.
Whether due to a sudden change in conditions, or as part of a managed monitoring strategy, we give you the detailed analysis you need to quickly identify integrity issues and make qualified decisions about appropriate remedial action.
When well access becomes a challenge, operators turn to READ. We help them navigate their way safely. Whether re-perforating, working over or abandoning a well, we provide simple, ironclad answers to help resolve complex well access issues.
Count on us to help you understand the limits of restricted access and any downhole hazards. We provide a quantified assessment of the risks and take your well intervention planning to the next level. We transform field data from on-site reconnaissance to valuable well intelligence.
By utilising READ’s range of multifinger calipers, we provide close inspection of every component from BOP to TD. This includes safety valves, injection valves, gas lift valves, polished bore receptacles, seal bore expansion joints and landing profiles.
Whether open, closed, blocked or obstructed, our Fast Turn Around analysis brings you straightforward answers. These answers simplify the complex, so you can maintain safe and efficient production. On-site, our engineers acquire high density, high resolution 3D geometric data that is second to none. And READ ANSA is on hand 24/7 for data analysis support.
Operators need rapid, comprehensive information about the location, extent and volume of deposits to help keep their wells producing freely and safety. That’s where READ comes in.
When deposits threaten to choke production or compromise critical safety systems, you can rely on us. We supply the data you need to perform targeted and effective remediation, fast.
We scrutinise well geometries to give you a quantitative map of deposits, revealing their impact and severity so you can respond in the right way. And using time-lapse condition assessments we’ll verify the success of your actions. This helps you manage the frequency of interventions – and ultimately maximise performance and minimise cost.
Whether asphaltine, wax or scale; and whether completion, perforating or safety valve. We uncover the inside story to keep you in complete control of the obstacles you may face.
Whether you’re looking for a green light on drilling the next section, or optimising designs for future wells, we work with you every step of the way. We provide fast, straightforward answers that detail the integrity of your wells during drilling operations, and help you deliver them safely and more efficiently.
We deliver near-instant answers that reveal the optimal location for plug and packer installation. This enables operators to make qualified, on-the-spot decisions with total confidence.
From drilling and completion, through to well abandonment, we’ll help you successfully achieve the containment you need. First time, every time, we’ll help you maximise safety and minimise costs.
Whether landing a hangar, straddle or retrievable bridge plug, we give you a detailed examination of inner diameter, ovality, metal loss, deformation and deposits. And you can fast-track the identification of clean-up or remedial requirements prior to attempted barrier installation.
Well integrity is a major issue in the oil and gas industry. When a leak occurs in one of your wells, we can provide the expertise to help you understand more about it and examine the possibilities to repair it.
A leak is characterised by its location and severity. These determine how it can be identified and what remedial action, if any, is available for its repair.
Leaks occur for wide range of reasons. The main causes are typically corrosion, erosion or mechanical failure. And with any unexplained pressure increase in the annulus, a leak must be considered.
The most commonly observed leaks are caused by holes in the pipe, leaks across packers or other sealing completion elements. Wash out leaks at completion items such as side pocket mandrels or gas lift valves and poorly made up joints are also common.
We offer a suite of solutions for identifying leaks that may be compromising well integrity. These include multifinger calipers, noise tools, sensors that measure changes in production characteristics and downhole imaging.
There are lots of reasons why downhole tubulars can lose their integrity. These range from holes, leaks and pressure changes to corrosion, scale and defects anywhere in the completion. We can help you identify the issues and advise you on appropriate remedial action.
We deliver detailed information about cement to casing, and cement to formation adhesion. This reveals a deeper understanding of barrier performance.
Whether you are running a first casing, working over or abandoning a well, we help you make qualified decisions about your cemented annuli.
In downhole environments, there is often the need for close tolerance on casing ID, thickness and ovality at critical locations in the well. This ensures optimum conditions for packer setting and burst/collapse calculations.
READ helps operators pre-select the best casing joints for these critical zones. We log the pipe in the yard before deployment downhole to verify the dimensional properties of individual joints.
Then once the casing is run in the well, we help you identify any potential drilling damage on the joints of known dimensions. This is done by in-well logging for a direct comparison. This is an extremely effective technique for selecting optimum packer setting sites and gaining confidence in burst/collapse tolerances.
ZeroWear™ Multifinger Caliper Sensors
Our ZeroWear™ multifinger caliper sensors offer a unique and revolutionary approach to well integrity data acquisition in hostile environments. They have been designed and engineered in-house by READ. We have successfully laboratory and field tested these pioneering sensors which achieve a far greater level of precision in high H2S/CO2 conditions, compared to standard tungsten carbide coated sensors.
It’s easy to see why operators choose READ as their well integrity partner
