1. n. [Drilling]

An abbreviated recovery and replacement of the drillstring in the wellbore that usually includes the bit and bottomhole assembly passing by all of the openhole , or at least all of the openhole that is thought to be potentially troublesome. This trip varies from the short trip or the round trip only in its function and length. Wiper trips are commonly used when a particular zone is troublesome or if hole-cleaning efficiency is questionable.

Compared with stationary circulation hole cleaning, the use of the wiper trip produces a more efficient clean out.

For a given operational condition, there is an optimum wiper trip speed at which the solids can be completely removed.

Nozzles with a correctly selected jet arrangement yield a higher optimum wiper trip speed and provide a more efficient clean out.

The hole cleaning efficiency is dependent on the deviation angle, fluid type, particle size, and nozzle type.

Correlation's have been developed that predict the optimum wiper trip speed and the quantity of solids removed from and remaining in the wellbore for given operating conditions. The wiper trip provides an advantage for hole cleaning and can be modeled to provide efficient operations.

Solids transport and wellbore cleanouts can be very effective using Coiled Tubing techniques, if one has the knowledge and understanding of how the various parameters interact with one another. Poor transport can have a negative effect on the wellbore whether it is for coiled tubing drilling or cleanouts, which may cause sand bridging and as a result getting the coiled tubing stuck. Coiled Tubing can be a very cost-effective technology when the overall process is well designed and executed. The highly deviated/horizontal well has placed a premium on having a reliable body of knowledge about solids transport in single and multi-phase conditions.

In our previous studies 1 – 2   , a comprehensive experimental test of solids’ transport for the stationary circulation was conducted, which included the effect of liquid/gas volume flow rate ratio, ROP, deviation angle, circulation fluid properties, particle size, fluid rheology, and pipe eccentricity on solids transport. Based on the test results the data was analyzed, correlation's were developed, and a computer program was developed.

In this study, the wiper trip hole cleaning effectiveness was investigated with various solids transport parameters such as, deviation angle, fluid type, particle size, and nozzle type. Based on these test results, an existing computer program was modified and adjusted to include these additional parameters and their effect on wiper trip hole cleaning.

The flow loop shown in Figure 1 was used for this project. It was developed in a previous study 1 – 2   . The flow loop has been designed to simulate a wellbore in full scale. This flow loop consists of a 20ft long transparent lexan pipe with a 5-inch inner diameter to simulate the open hole and a 1-1/2" inch steel inner pipe to simulate coiled tubing. The flowloop was modified and hydraulic rams were installed to enable movement of the tubing (see figure 2 ). The inner pipe can be positioned and moved in and out of the lexan to simulate a wiper trip. The loop is mounted on a rigid guide rail and can be inclined at any angle in the range of 0°–90° from vertical.

When the coiled tubing is in the test section, circulating the sand into the test section and build an initial sand bed with an uniform height cross the whole test section. Then pull the coil out of the test section with a preset speed.

The recorded parameters include flow rates, initial sand bed height before the coiled tubing is pulled out of the hole (POOTH), and final sand bed height after the coil tubing is POOTH, fluid temperature, pressure drop cross the test section and wiper trip speed. The data collected from the instrumentation is recorded using a computer controlled data acquisition program, see reference 1 for more information.

In this study, over 600 tests have been conducted using three different particle sizes 2   , over a range of liquid and gas rates at angles of 65° and 90° from vertical. The way in which the wiper trip affects the various solids transport parameters was investigated. The results and discussion in this paper focus on the situation that involves wiper trip hole cleaning in which the tubing is pulled out of the hole, while circulating water, gel, and multiphase gas combinations.

‘Wiper trip’ is defined in this paper, as the movement of the end of the coiled tubing in and out of the hole, a certain distance. For various reasons the study focused on the wiper trip situation of pulling the coiled tubing out of the hole. The critical velocity correlation developed in a previous study 1   can be used to predict the solids transport for the coiled tubing run-in-hole (RIH).

The wiper trip is an end effect. When the circulation fluids are pumped down through the coil and out of the end, and returned to surface through the annulus, the flow changes direction around the end of the coil and the jet action only fluidizes the solids near the end of the coil. When the flow conditions are less than the critical condition solids will fall out of suspension for a highly deviated wellbore. Then the sands transport with the sliding and dragging mode.

Based on the experimental observation in this study, for a given set of conditions, there is an optimum wiper trip speed at or below which sands can be removed completely when the coil is pulled out of the hole. When the coil tubing is POOTH at a wiper trip speed higher than the optimum wiper trip speed, there is some sand left behind. In general, more sand is left in the hole as the wiper trip speed is increased. The hole cleaning efficiency is defined as the percentage of sand volume removed from the hole after the wiper trip versus the initial sand volume before the wiper trip. 100% hole cleaning efficiency means that the hole was completely cleaned. In general a higher pump rate results in a higher optimum wiper trip speed. The vertical axis of figure 3 is equal to 100% minus the hole cleaning efficiency. For a given type of nozzle and deviation angle, there is a minimum flowrate at which the hole cleaning efficiency is near to zero. For low pump rate, the remaining sand volume in the hole increases non-linearly with the dimensionless wiper trip speed. However, with high flowrate, the remaining sand volume in the hole increases linearly with the dimensionless wiper trip speed. Figure 3 displays these three parameters that can be correlated and used to select adequate flowrates and wiper trip speed to ensure an effective cleanout operation. If the pump rate is too low or the coiled tubing is pulled out of the hole too fast solids will be left behind.

Hole cleaning efficiency for water at 90° with Nozzle B

There are other variables, which can affect the hole cleaning effectiveness during wiper trip cleanouts. The effect of the following variables are investigated in this study:

Nozzle type

Particle size

Deviation angle

Multi-phase flow effect

Effect of nozzle type.

In this study three different nozzle types were investigated. For simplicity the nozzles can be referred to as Nozzle A, B, and C. Each of these three nozzles had different jet configurations and size. The effective wiper trip hole cleaning time was investigated for each nozzle type and the optimum wiper trip speed for a wide range of flow rates was determined. Previous ‘rules of thumb’ assumed that the cleanup of a wellbore takes approximately two hole volumes for a vertical wellbore. From these experimental studies, it has been observed that these ‘rules of thumb’ are inadequate.

Figure 4 displays the number of hole-volumes required to clean the hole using water in a horizontal section of a well for the three different nozzle types. There is a non-linear relationship between the number of hole volumes and the in-situ liquid velocity. For a given type of nozzle, the number of hole-volume needed is constant when the in-situ liquid velocity is high enough. However with a low in-situ liquid velocity, the number of hole-volume increases dramatically with the decreasing of the pump rate. An important thing to note is that, in certain ranges, the hole will not be sufficiently cleaned out if the minimum in-situ velocity is not attained and this value will vary depending on the type of nozzle. It is essential to select the proper nozzle configuration and wiper trip speed to ensure an effective cleanout. The solids transport parameters that are interacting with one another (shown in figures 3 and 4 ) can be correlated using a dimensionless wiper trip speed parameter. From this information the proper nozzle, flowrates, and wiper trip speed can be selected to provide an effective cleanout.

Effect of particle size

The previous study results 2   indicate that there is a particle size that poses the most difficulty to clean out with water for the stationary circulation mode and from the study it is of the order of 0.76mm diameter frac sand. In contrast to stationary circulation hole cleaning, the wiper trip hole cleaning situation reveals different conclusions based on particle size. In this study three types of particles ranging in size were investigated: 1) Wellbore fines, 2)frac sand, 3) drilled cuttings. Figure 5 displays the results of the investigation of particle size that included a wide range and the results suggest that for the horizontal wellbore with a high pump rate, larger particles have a higher hole cleaning efficiency than smaller particles do. But for low pump rate, it was just opposite.

Effect of particle size on the hole cleaning efficiency with water at 90°

The effect of particle size on solids transport is different between stationary circulation and wiper trip hole cleaning. Due to the complexity of the interaction between the various solids transport parameters it is a challenge to generalize and draw conclusions. For more information on particle size effects please refer to reference 2.

Effect of fluid type

Wiper trip hole cleaning adds a new dimension with respect to fluid type. In contrast to stationary circulation hole cleaning where gel could not pick up the solids and only flowed over top of the solids bed 2   , for the highly deviated wellbore the wiper trip hole cleaning method transports the solids effectively. Due to the turbulence created at the end of the coiled tubing from the fluid, gels have the ability to pick up and entrain solids and transport them along the wellbore. For small particles like wellbore fines the use of gel for long horizontal sections is beneficial. The larger particles such as frac sand or drilled cuttings, tend to fall out at a more rapid pace.

The effect of fluid type on the hole cleaning efficiency is shown in figure 6 . There is no significant different between Xanvis and HEC for all tested flowrates. There is no difference between water and gel except for very low pump rates i.e. at very low shear rates, when gels outperform water/brines. Therefore, in the case where the liquid in-situ velocity is low, pumping gel would clean the hole better.

Effect of fluid type on the hole cleaning efficiency at 65°

Effect of deviation angle

The experimental results in the previous study 1   shows that the highest minimum in-situ liquid velocity is needed around 60°. The effect of deviation angle on the hole cleaning efficiency with the wiper trip mode is shown in figure 7 . The general trend at higher flowrates typical for 1-1/2" coiled tubing is that there is not a significant difference in solids transport effectiveness between horizontal and 65 degrees. There are distinct differences for fluid types as well, for example with water, solids transport proves more difficult at 65 degrees than at horizontal, but, with Xanvis gel, 65 degrees is easier, than horizontal.

Effect of deviation angle on the hole cleaning efficiency with water

Multi-phase flow is very complex and if used incorrectly can be a disadvantage and provide poor hole cleaning, whereas if the addition of the gas phase is understood, there are advantages that prove beneficial for solids transport. Figure 8 and 9 display the multi-phase flow effect for various gas volume fractions. The addition of the gas phase up to a gas volume fraction (GVF) of 50% in stationary circulation, hole cleaning can be improved by up to 50%. Whereas with wiper trip hole cleaning, the addition of the gas phase up to GVF 50%, only produces an improved cleanout effectiveness of 10–20%. For example, if the well was 80% cleaned out with water in the wiper trip hole cleaning mode, with the addition of the gas phase, the solids transport effectiveness could be increased to 85%. Even though with stationary circulation hole cleaning there is a substantial increase in hole cleaning effectiveness with the addition of the gas phase, the use of the wiper trip method is more effective, than just the addition of the gas phase. The addition of the gas phase is beneficial in low pressure reservoirs and where there are limitations due to hydrostatic conditions.

Effect of gas volume fraction on the optimum wiper trip speed for water/gas at 90°

As shown in figure 8 , there is not a significant effect on solids transport effectiveness with the addition of the gas phase at high relative in-situ liquid velocities. As the relative in-situ liquid velocity is decreased to a low value, solids transport effectiveness is dependent on the addition of the gas phase. As the gas phase is added the solids transport effectiveness decreases, until more gas is added and the relative in-situ velocity starts to increase, which causes an improvement in solids transport effectiveness.

Figure 9 displays the effect of adding gas to the system resulting in a decrease in optimum wiper trip speed. The three curves represent situations that involve the addition of gas and the reduction of the liquid flow rate, keeping the total combined flow rate constant. There is a greater dependency on the addition of gas at the higher total flowrates on the optimum wiper trip speed compared to the lower flowrates. As more gas is added with a constant total combined flow rate the optimum wiper trip speed decreases, but the solids transport effectiveness generally improves when gas is added to the system with a fixed liquid flow rate as shown in figure 8 . The complexity of the multi-phase flow behavior makes more difficult to generalize the test results. More data is required to develop a reliable correlation to predict the effect of the gas phase on the optimum wiper trip speed and the hole cleaning efficiency.

Based on the experimental study and the analysis of the hole cleaning process, the following conclusions can be made:

Compared with stationary circulation hole cleaning, the use of the wiper trip produces a more effective clean out.

For a given set of well conditions, there is an optimum wiper trip speed at which the solids can be completely removed. The optimum wiper trip speed is dependent on the deviation angle, fluid type, particle size, and nozzle type. Nozzles with correctly selected jet arrangements yield an effective cleanout operation.

The investigation of particle size included a wide range and the results suggest that when the borehole is at various inclined angles for particles from 0.15 mm up to 7mm in diameter, there is a significant effect on solids transport. Spherical particles such as frac sand, are the easiest to clean out and wellbore fines prove more difficult, but the larger particles such as drilled cuttings pose the greatest difficulty for solids transport.

Fluid rheology plays an important role for solids transport, and to achieve optimum results for hole cleaning, the best way to pick up solids is with a low viscosity fluid in turbulent flow but to maximize the carrying capacity a gel or a multiphase system should be used to transport the solids out of the wellbore.

The large number of independent variables influencing solids transport demands that a computer model be used to make predictions effectively.
