Sand in my Valve!

Sand production is a common problem in the oil and gas industry and can have significant impacts on the performance and reliability of a surface controlled sub-surface safety valve (SCSSV). Sand production occurs when sand particles are produced along with the oil or gas and can cause damage to the valve and its components, leading to failure. In this essay, we will discuss the effects of sand production on a SCSSV and some ways to prevent failure. One of the main effects of sand production on a SCSSV is erosion. Sand particles can cause abrasion to the valve body and its components, leading to corrosion and eventual failure. Sand particles can also accumulate in the valve body and cause obstructions, reducing its ability to function properly. This can lead to increased pressure and stress on the valve components, further increasing the likelihood of failure.

Another effect of sand production on a SCSSV is clogging. Sand particles can accumulate in the valve body and restrict the flow of fluid, reducing its ability to function properly. This can lead to increased pressure and stress on the valve components, further increasing the likelihood of failure. Clogging can also make it difficult to remove the valve for maintenance or repair, leading to further operational issues (to hear about how debris in a wellborn can cause problems - check out what happened with a SCSSSV Isolation Sleeve www.ballycattertech.com/detail-view-blog/39/completions). To prevent the effects of sand production on a SCSSV, it is important to implement preventative measures to reduce the amount of sand that is produced. One such measure is to use a sand control technique, such as gravel packing or screen installation, to prevent sand from entering the production tubing. This can help to reduce the amount of sand that reaches the SCSSV, reducing the likelihood of erosion, clogging, and other issues.

Sand screens really work

Another measure to prevent the effects of sand production on a SCSSV is to install a sand screen in the well. Sand screens are designed to stop sand particles in the fluid before it reaches the valve, reducing the amount of sand that enters the valve body and its components. This can help to reduce erosion, clogging, and other issues, improving the reliability and performance of the SCSSV. In addition to these preventative measures, it is also important to regularly inspect and maintain the SCSSV to ensure its proper functioning. This may include pulling and cleaning the valve body, checking for signs of erosion, and replacing damaged components as necessary. Regular intervention maintenance can help to reduce the likelihood of failure and prolong the lifespan of the SCSSV.

In conclusion, sand production can have significant impacts on the performance and reliability of a SCSSV. The effects of sand production can include erosion, clogging, and other issues that can lead to valve failure. To prevent the effects of sand production on a SCSSV, it is important to implement preventative measures such as sand screens, gravel packs, and regular well intervention maintenance. By taking these steps, it is possible to reduce the likelihood of failure and ensure the safe and reliable operation of a SCSSV.

Where to Place an Offshore Platform When a major oil and gas operator wanted a new concrete gravity based platform placed in their existing subsea field, they asked us to figure out where to put it. At first it may seem like an easy task, pick a nice flat piece of seabed and job done. It is not that simple, however, and it took a multi-disciplinary team to get the optimum solution. Like all engineering issues, it is all about weighing the trade-offs between alternatives. Factors to consider in the placement of an offshore platform include drilling and completion costs, subsea infrastructure, and environmental impact, to name a few. These factors will impact the longer term viability of an offshore asset and it’s overall operability as infrastructure is added in the field. The drilling and completion costs are the most obvious to have be directly impacted by the surface position of an offshore platform. Here the overall drill and complete cost, as well as ability to reach geologic targets is based on the surface location of the platform, i.e. the starting surface location for all wells. Typically, platform placement is as close to the “center” of the pool as possible to enable the easiest options to access all parts of the structure, however, factors such as the desire to have horizontal completions, specific azimuths through a stress field, or a secondary geologic prospect, may move the platform from the “default” bullseye position. It is important to have an asset development plan from subsurface available (as mature as possible), to plan completions and trajectories for potential platform positions.
Slickline vs. Coiled Tubing Well interventions can be highly profitable and there are a number of tools to use. Slickline and coiled tubing are the most commonly used and flexible equipment to diagnose and remediate well issues.. Slickline is perhaps the simplest well intervention tool. It is a single strand "piano wire" that due to it's smooth surface is able to have a packing seal directly on the wire, hence the "slick" term. Slickline is in the category of wireline which includes braided and electric line which has strands of wire wrapped together, creating spaces between the strands of wire which requires grease packing to create an effective seal (and hence not "slick"). Slickline can be truck or skid mounted for use on- or offshore and lightweight units can even be transported by helicopter. The wire is wrapped on a drum and a winch is used to run the wire in and out of the well using weights on the end of the wire. A variety of tools can be run on slickline to perform mechanical actions such as setting and pulling plugs, pressure gauges, or safety valves. It is referred to as a wireline which also includes braided line and electric line. Electronic timers can be used to deploy tools using triggers and battery-powered tools. Coiled tubing is also used through tubing and consists of a continuous pipe rolled on a drum with a swivel connection allowing the coil to run "slick" through a packoff and has the advantage of being able to pump through the inside of the coil.
