“…Conventional non-deformable granular TPA can be subdivided into water-soluble or acid-soluble inorganic salt particles, oil-soluble particles, and temperature-sensitive degradable particles. These particles mainly rely on the particle bridge plugging effect to form temporary plugging layers at fractures or pore throats and follow to meet the plugging requirement that the particle size should be larger than 1/3-1/2 of the pore throat size (Cargnel and Luzardo 1999). Huo (2009) used oil-soluble resins with different softening points to synthesize a new type of oil-soluble temporary plugging agent.…”

“…The performance of the wax balls could meet the requirements of the temporary plugging and repeated fracturing process in the Ansai Oilfield, China, with excellent performance and reasonable cost. Cargnel and Luzardo (1999) found calcium carbonate (CaCO 3 ) could be used as a bridging agent and applied in drill-in fluids; it can prevent massive loss circulation to the reservoir formation (Nasiri et al 2017).…”

Development of degradable pre-formed particle gel (DPPG) as temporary plugging agent for petroleum drilling and production

et al. 2020

Temporary plugging agent (TPA) is widely used in many fields of petroleum reservoir drilling and production, such as temporary plugging while drilling and petroleum well stimulation by diverting in acidizing or fracturing operations. The commonly used TPA mainly includes hard particles, fibers, gels, and composite systems. However, current particles have many limitations in applications, such as insufficient plugging strength and slow degradation rate. In this paper, a degradable pre-formed particle gel (DPPG) was developed. Experimental results show that the DPPG has an excellent static swelling effect and self-degradation performance. With a decrease in the concentration of total monomers or cross-linker, the swelling volume of the synthesized DPPG gradually increases. However, the entire self-degradation time gradually decreases. The increase in 2-acrylamide-2-methylpropanesulfonic acid (AMPS) in the DPPG composition can significantly increase its swelling ratio and shorten the self-degradation time. Moreover, DPPG has excellent high-temperature resistance (150 °C) and high-salinity resistance (200,000 mg/L NaCl). Core displacement results show that the DPPG has a perfect plugging effect in the porous media (the plugging pressure gradient was as high as 21.12 MPa), and the damage to the formation after degradation is incredibly minor. Therefore, the DPPG can be used as an up-and-coming TPA in oil fields.

“…The three mechanisms are shown in the following figures: Similarly, the solid invasion into the porous formation can be classified into three main types: surface bridging, shallow plugging, and deep invasion. The fine solids penetrate into the porous formation and eventually accumulate and block the pore throats by forming an internal filter cake [26].…”

“…The formation of such filter cake should take place in the near wellbore pores (i.e. an external filter cake) [26]. This will help minimize formation damage by avoiding the formation of an internal filter cake which is harder to remove [27].…”

The ever-increasing targets of drilling depth and reach, coupled with locational disadvantages have driven the oilfield drilling operations into new technology frontiers. Drilling fluids being an essential component of any successful drilling operation, adequate understanding of the impact of drilling fluid characteristics can eliminate a range of difficulties encountered during drilling operations and reduce drilling cost significantly.This article presents a comprehensive review of various types of drilling fluid systems and technology advancements and also the significant challenges faced by a drilling fluid engineer, starting with the basics and ending with extreme reservoir Conditions, with special emphasis on non-damaging drilling fluids. This paper is specially written for fresh petroleum engineering graduates and entry level drilling fluid engineers and drilling engineers as well as for drilling fluid research groups who would find many important information for a given drilling and reservoir challenge.

“…Calcium carbonate (15 g fine and 5 g medium): Calcium carbonate (CaCO3) was particularly beneficial for reducing fluid loss and used to form morestable external filter cakes. The weighting ratio of calcium carbonate fine size and medium size was 1:3 because this ratio was recommended to rapidly bridge the formation (Cargnel and Luzardo 1999).…”

The application of potassium chloride (KCl) as a temporary clay stabilizing additive in water-based drilling fluids is problematic in chloride-sensitive formations.However, failure to utilize clay stabilization leads to additional costs to drilling operations due to wellbore stability and drilling fluid residual problems. In addition, the chloride ions can be defined as a contaminant in land operations, with the potential to inhibit the growth of vegetation and the potential to pollute aquifers. The purpose of this study is to propose a new, high performance water-based fluid system using potassium nitrate instead of potassium chloride as the clay stabilizing additive for drilling applications.Water-based drilling fluids using potassium nitrate and potassium chloride, respectively, were prepared with a density of 1.3 S.G. using various weighting materials.Capillary suction time (CST) test was used to optimize the potassium salt concentration in drilling fluids for effective clay swelling inhibition. HPHT filtration tests under static and dynamic conditions were conducted at 250°F and 300 psi. Berea sandstone cores with an average porosity of 23 vol% and an average permeability of 50 md were used in the filtration tests. The rheological properties, the volume of filtrate, and the filter cake thickness of the water-based drilling fluids were determined and compared.The CST tests show that potassium nitrate performs comparably to potassium chloride as a clay stabilizer. However, the water-based drilling fluid containing potassium nitrate has better rheological properties than that containing potassium iii chloride. The HPHT filtration press tests show that water-based drilling fluid with potassium nitrate has a low filtration volume, less than 1 mL out of a total solution of 200 -250 mL, when using barite as the weighting material. This paper not only highlights the successful replacement of KCl by KNO3 to achieve good rheological properties in water-based drilling fluids, but also shows that KNO3-based drilling fluids are more economical as well as environmentally friendly than KCl-based drilling fluids in drilling waste management. iv DEDICATION To my family. v ACKNOWLEDGEMENTS I would like to thank my committee chair, Dr. Nasr-El-Din, and my committee members, Dr. El-Halwagi and Dr. Noynaert, for their guidance and support throughout the course of this research.Thanks also go to my friends and colleagues and the department faculty and staff for making my time at Texas A&M University a great experience. I also want to extend my gratitude to the survey instrument, and to all the Texas elementary teachers and students who were willing to participate in the study.
