When it comes to end-of-well operations, you need absolute clarity about what is in your well to make informed and confident decisions for well abandonment.
ANSA offers clients a range of independent P&A (Plug & Abandonment) analysis solutions to help assess the condition of mature assets and reservoirs. As a result, our expert advisors can bring valuable insight into the design and execution phases of any P&A program.
We understand the critical nature of P&A obligations. There are economic, operational, safety and environmental considerations. Having high quality, impartial information available at the right time is crucial. It helps keep costs within budget. Additionally, it ensures well operations are conducted safely and efficiently to safeguard the long-term well integrity required.
Do you need a quick, accurate yes/no answer about whether you can proceed with abandoning your well? ANSA can help expedite your P&A operations with our rapid 3-hour ISOLATION-view service. ISOLATION-view takes a quantitative look at cement evaluation and answers these key questions:
ANSA analyses newly-acquired cement logging data and advises in real-time on whether you can proceed with the abandonment stage of your P&A process.
Equally, using your historical cement bond data, we will provide up-front analysis of your prior bond logging. This supports fast decision making, removes unnecessary costs from your P&A plans and eliminates uncertainty around re-logging.
Our ISOLATION-view service includes:
We’ll calculate your total cement zonal isolation and total continuous cemented zone. These will be clearly displayed on the report front cover.
Could you have masses of untapped intelligence about your wells within your organization? Often, existing datasets can be tucked away and their true value can remain unexploited, often for many years.
More importantly, legacy data can be extremely beneficial to P&A program planning. Our team of experts can help you unlock further value from surveys you have already acquired by reviewing historical data to determine the need for logging runs.
This can be a simple review of a PDF log, digitized and reprocessed data, or a full study including casing integrity data, lithology logs and cement reports.
All over the world, we provide operators with crucial insight into their subsurface lithology to support safe and efficient end-of-well operations.
Certain formations, such as shale and salt, can create a seal within the annulus. So we analyse casing integrity data acquired using multifinger caliper or ultrasonic technologies, alongside cement evaluation data. With this information, we can determine if your formation could potentially be acting as an effective barrier in conjunction with cement already in place.
In short, you can trust our geoscientific experts to conduct a thorough review of new and/or historical data about your formation. They combine it with their in-depth knowledge of the world’s regional geologies to bring certainty to your P&A decision making.
We provide comprehensive cased hole analysis training programs for both operators and service companies to help clients build their in-house data analytics capabilities.
Furthermore, we can integrate seamlessly with your team to provide expert insights during on-the-job training. We’ll help with your pre-job planning by delivering impartial advice on logging programs and tool selection.
Also, we are happy to perform an independent review of any third party technical logging proposals you’ve received.
