Wong GK, Fair PS, Bland KF, Sherwood RS (2003) Balancing act: Gulf of Mexico sand control completions peak rate versus risk of sand control failure. Proc SPE Ann Tech Conf Exhib. https://doi.org/10.2523/84497-ms However, the width size range for the keystone or straight slots is limited to a minimum of 0.012 inches to a maximum of 0.25 inches.
Initially, the screens will only capture large sand particles which build up to form a filtration cake which proceeds and capture both large and fine particles. viii. Expandable sand Control Screens Among various sand control methods, the screen-only completions are considered the preferred option for the sand control method for unconsolidated formations, as these methods maximize productivity and minimize completion complexity and cost. This is consistent with a new approach by Parlar et al. ( 2016), which suggests that to select sand control options, one should start with the simplest and most cost-effective sand control, and move to select the complex and expensive options if the simple ones do not meet the design criteria for the project. A stand-alone screen is usually the first choice for completing an openhole completion that is prone to sand production (Hodge et al. 2002). The straight slots are more economical and have a higher resistance to wear and tear but also have a higher probability of clogging compared to keystone.

It may be expensive and time-consuming to conduct many laboratory sand retention test experiments for selecting the effective sand control method. Numerical models and software have been developed using experimental data from laboratory test. The aim of conducting numerical simulations for screen size selection is to avoid repeating laboratory tests in areas where extensive sand retention test data are available. Currently, numerical modeling does not accurately account for interactions between fluids and the particles (Agunloye and Utunedi 2014; Wu et al. 2016; Feng et al. 2012; Mondal et al. 2010; Markested et al. 1996; Constien and Skidmore 2006). Chen et al. ( 2016) developed a new test apparatus to offer more accurate screen performance evaluation. They concerned that the current laboratory tests use a small screen disk, due to its convenience and low cost. The current test methods can only test the minimal opening size and pressure drop of local screen material and could not effectively reflect the performance of an integrated screen pipe run in the wellbore.
Continue to do the injections at a constant rate as you empty the collection container once per litre At low velocities, the relationship between erosion and velocity can be linear at constant particle size and concentration. However, a nonlinear power-law relationship was observed when the particle concentration was changed with increasing velocity. Conversely, the diffracted beam’s intensity at any given angle measures the number of particles with a given cross-sectional area in the beam’s path. This method uses non-intrusive measures to control, mitigate or avoid sand production from the reservoir. The following techniques are passive sand control methods. The cost of owning a sand screen control varies to the type, design, and size of the screen selected.On Tuesday, July 6th 2021, 3M will be demonstrating in more detail how the Ceramic Sand Screen Systems can offer effective sand control and long term productivity for your wells in a free online webinar. Notably, the sonic sifter can better handle finer particles compared to the mechanical sieve shaker. Laser Particle Sizing Analysis (LPSA) All these are dependent on your intended application. Below are the major types of sand screens available in the market. Slotted Liner Sand Screen
ceramic sand screens efficiently control sand to help lower capital expenditures and maximize flow capacity, productivity and well life. You need to remove these impurities at the drilling point to avoid transferring them to the refining facility.

American Petroleum Institute, New York, pp 189–201Delivers reservoir compliance and positive wellbore support while providing unprecedented installation simplicity, flexibility, and life-of-well reliability. Sanders opened the session by describing the basic design of the ceramic sand screens. The equipment is made up of a perforated base pipe with ceramic rings placed over on top. These rings have ridges that create a profile and provide the sand control. The solution comes in modules of 1.5m length and is available in a range of different sizes. Next, the sample is added to the water reservoir. For better sample dispersion, you can use ultrasonic agitation either before or during the sample measurement.

Most of the experimental studies have been conducted using air or water as carrier fluids. Very few studies on sand screens were conducted using more viscous fluids. Therefore, more studies are needed to examine sand screen erosion under various conditions of fluid viscosity and density. Bitter JGA (1963) A study of erosion phenomena part II. Wear 6(3):169–190. https://doi.org/10.1016/0043-1648(63)90003-6 Using this method, you place your sample on a fully automated laser diffraction analysis unit and get your readings on the computer. · Dry Sieving
If the screens have huge holes, a large quantity of sand will enter the bore leading to sand plugging. Most of the experimental studies on sand screens found that, as the sand concentration increases, the erosion of sand screens initially increases and then decreases after reaching a certain peak value.
