The aim of this project is to improve the well treatment method using resin coated material. The project is experimentally oriented and investigates the influence of the resin percentage in the coating method on compressive strength, permeability and porosity. There are opportunities to use local sand as a resin coating, which will be a very economical method and can be commercialized.

It is my sincere hope to express utmost gratitude to all persons and departments who directly or indirectly contributed to the successful completion of my last year project I and II. First of all, I would like to praise Allah Almighty, for His guidance and blessings that had made my final year project go smoothly and successfully. Besides that, I would like to express my appreciation to Dahlila Kamat, Masters student in Petroleum Engineering Department for her guidance throughout the project, all technicians in Civil Engineering Department and Mr Jukhairi who help me with permeability and porosity machine in Core lab (Block 15).

Also, I would like to express my gratitude to my UTP supervisors, Ms. Raja Rajeswary Suppiah for good supervision throughout my final year project. Last but not least, I would like to express my special thanks to my colleagues, friends and family who have inspired me and given full support to complete this project successfully.

From this experiment, we need to obtain a certain curing time, temperature, heat and concentration to obtain a satisfactory result in terms of compressive strength and permeability. This project will be the first to use local sand as resin-coated sand to solve this problem. To experimentally study the best compressive strength of resin coated sand with specific resin concentration. ii.

To conduct the experimental study on the best permeability result of resin coated sand to increase production with different percentage of resin. iii. The evaluation parameters will be the effect on baking time, temperature, heat and resin concentration to get the best result of local sand coating. The focus of the project is to achieve the best result of compressive strength and permeability as it is the important criteria for increasing oil and gas production. a) The experiment performed in the laboratory b) Relevant research journals c) Assistant from the master student d) Market chemicals.


In particular embodiments of the present invention, however, the particles used may be coated with a consolidating agent in an amount of at least approx. 5% or in the range from approx. 5.5% to approx. 50% by weight of the particles. A stylized view of the distinction between the traditional consolidating agent coating and the consolidating agent coatings of the present invention is provided in FIG. 1. 1(a) illustrates a situation where only approx. 20-25% of the particles are coated with consolidating agent, but that percentage is coated with a relatively larger coating of consolidating agent.

1(b) illustrates a situation in which approximately 90-100% of the particles are covered with a traditional thickness coating of consolidant. 1(a) and 1(b), the same amount of consolidation agent was used to coat, but in FIG. The greater coverage of consolidation agent on the first (coated) portion of the particles can have numerous advantages.

By covering only part of the particles with this larger coating, more reinforcing agent is concentrated at the contact points between the grains of the particles. These larger gaps, or voids, can help improve the conductivity of the particle packages without reducing their consolidation strength. Among other things, the methods of the present invention can be used such that the total volume of consolidatant used is less than traditionally required to achieve effect.

Alternatively, as described above, the methods of the present invention may use the same amount of consolidating agent coated on a smaller portion of the particles, in which case, while a direct cost benefit from reduced consolidating agent use may not be seen, cost savings may be be. still occur due to the fact that the coating of fewer particles can lead to simplified operating procedures, reduced horsepower requirement and reduced equipment use. In accordance with certain methods of the present invention, one method of achieving such greater coverages of consolidating agent without significantly increasing the cost is to use the same amount of consolidating agent that would be used to compact an entire batch of particles in a traditional underground application, but use that amount of consolidant to cover only a fraction of the total amount of particles. In addition, the glass transition temperature and melting temperature of each of the cured resin systems were determined.

The concentration of the alcohol will depend on its solubility in the resin selected for treatment. The above test results clearly show the effect of softening agents on the compressive strength of the dried samples. While sample (B and C) with only one of the softening agents gave improved results, sample D with both softening agents gave the best results.

FIG.  1(a)  illustrates  a  situation  wherein  only  about  20-25%  of  the  particulates  are  coated  with  consolidating  agent,  but  that  percentage  is  coated  with  a  relatively  greater coating of consolidating agent

We want to be sure in advance that the production of the preferred sand with a resin layer is improved. PRE-EDX combined with seminar/poster exhibition/submission of final report (CD Softcopy & Softbound). After mixing the sand and resin, put it into the mold (same as the manual mixing procedure).

Before using the samples for compressive strength tests, I managed to test some small tests such as transit time, path length, elastic modulus and speed.

A rock can be very porous and yet impermeable if there is no communication between the pores. Because those pore spaces do not fully communicate with each other, only when those pores are efficiently connected can oil be recovered from the formation. a) Compressive strength test: Maximum load and strain. The good result of the best compressive strength of the resin coating will give us the best compressive strength.

The highest compressive strength is selected so that the resin-coated layer can withstand any pressure changes in the formation. While for mixed mix the best compressive strength result is sample 7 with maximum load value 121 KN and stress value 48.4 MPA. Density is related to transit time, the denser the nucleus, the fastest time it passes through.

Both experiments (Hand Mixing and Blend Mixing) show that Sample 5 has the highest transit time score. The hand mixing experiment gives the result of 10 mm as the largest path length according to sample 4 and 5. The mixer mixing experiment recorded sample 4 as the largest path length which is 12 mm. d) Speed. By hand mixing, sample 3 gives the highest velocity value which is 450 m/s, while by mixer, sample 5 is recorded as the highest velocity value which is 411 m/s. e) Elastic modulus.

The hand mixing experiment gives the highest result, which is 0.456 GN/m² from sample 3. The second highest result is sample 1 with a value of 0.423 GN/m². The mixer experiment gives the highest result of 0.468 GN/m² from sample 4. The second highest result is sample 3 with a value of 0.464 GN/m². f) Table permeability test. From the graph above, the highest permeability belongs to 5% resin concentration which is 347 md while the second highest is 340 md with 10% resin concentration.

The trend of the graph shows that by increasing the concentration of resin, the permeability of the sample decreases. The porosity graph above shows that the highest result belongs to 5% resin concentration which is 37% and followed by 15% resin concentration with 29%. Pore ​​volume of 5% resin concentration gives the highest result (17 cc), which supports the result of its highest porosity value (37%).

The reason for a high porosity due to 40% of resin concentration is due to a high value of pore volume which is 14cc.
