Stuck pipe causes delays in drill rig operations and increases downtime and production expense. It is essential to quickly resolve stuck pipe issues to prevent productivity and money loss.
Oil reservoirs often start production with a high formation pressure to force oil into the well and sometimes up to the surface through the tubing. However, this natural drive soon ends as the reservoir pressure declines.
Well Repair
Often water is produced in conjunction with oil and gas. This produced water containing salt and minerals must be separated from the gas and oil to ensure that freshwater aquifers are not contaminated. This is accomplished by dividing the gas, oil, and water using surface equipment and sending each to a separate storage pond. This process also involves relocating well sites and restoring the surrounding area to the original site condition.
A stuck pipe prevents a drill rig from continuing operations, costing the company immense money in lost production. Dialog provides wireline services that include pipe recovery Casper.
A stuck pipe is diagnosed with a pressure log that determines the location of the stuck point in the wellbore. The free pipe is separated from the stuck pipe by backing off or chemical cutting. Fishing tools can then be run downhole to latch onto and recover the free tubular. This is a valuable operation during Plugging and Abandonment (P & A) to minimize operational rig downtime.
Well Completion
The well completion process is the critical step between drilling and oil production. It involves setting up the pipeline and connecting the well to the reservoir. The completion also includes activities like hydraulic fracturing, which breaks up the formation and props them open to create new paths for oil to flow.
Materials management is another crucial part of the completion process. This includes ensuring proper proppant and fluids are delivered to the well during stimulation. This is especially important as lateral lengths are increasing and stage counts are growing.
Stuck pipe is a significant issue in the good completion process and can cost thousands of dollars per day in lost drilling operations and workover AFEs. The dialog can utilize a wireline technique called pipe recovery to free stuck pipes. In this procedure, the location of the stuck point is identified, and the free tubular is either backed off or cut with chemical or mechanical cutters. This will allow fishing tools to be run later to grab onto the free tubular and BHAs and pull them out of the good bore.
Well Abandonment
Abandonment is necessary for the oilfield lifecycle, but the process can be complex. Environmental concerns, governmental regulations, and limited well condition and integrity information add to the difficulty of abandoning wells.
Effective abandonment requires fully characterizing the site geology, construction of the abandoned well, and hydrogeology. This characterization is vital to preventing contamination of aquifers and avoiding water supply interruptions.
Despite the challenges, many operators in our focus group believe that new technology could improve abandonment efficiency. They also wanted to see well services providers more closely aligned with the drilling, engineering, and asset teams. This would enable service providers to understand the operators’ needs better and drive efficiencies in good abandonment. In addition, a more robust data management system that includes well-construction and characterization data could greatly simplify the abandonment process. This, in turn, could help lower the cost of the operation. It could also help reduce the potential for unforeseen problems.
Well Testing
Well-testing services help detect problems and prevent slackline and wireline oilfield operations downtime. From casing evaluation to advanced slackline and wireline testing capabilities, the company provides value across all phases of a well’s lifecycle.
Among the essential well-testing services is identifying downhole conditions that may result in stuck pipes. A stuck pipe is a standard drilling or workover problem that can cause delays in completing the drilling or workover safely, lost production, and demand more of your valuable resources.
Dialog’s team has state-of-the-art tools to free stuck pipes and get your well back up and running as quickly as possible. This service can be performed in various ways, from backing off to cutting the tubular with chemical cutters. A radial cement bond log compliments the freeing process by tracking multiple stuck point locations, not just the closest one. This allows you to choose the most cost-effective method for your situation.
