Apart from that early compressive strength helps to prevent the leakage of formation fluids into the wellbore during the cement setting. By doing so, well integrity and productivity is improved.

Poor removal of filtercake will lead to a failure in the ability of the cement to provide zonal isolation at the cement-formation interface (CFI), during completion and for the well's lifetime. Several chemical mechanisms (chelating agents, acids, enzymes, and oxidizers) have been widely employed to remove filtercake. Nonetheless, at certain circumstances, these strategies have drawbacks that can adversely impact oil-well productivity. This research introduces a novel preflush (KV-IIA as well as KV-IIB) developed in the laboratory to transform the water-based filtercake at CFI into cement-based materials to enhance shear bonding. KV-IIA solution contained 16% CaCl2, and 1% Alkyl Polyglucoside (APG-1214), while KV-IIB fluid comprised 1% Alkyl Polyglucoside (APG-0810), 12% NaOH, 15% Na2SiO3 and wa...

The nanoparticles contents were chosen at proportions corresponding to 1, 2, 3 and 4% by weight of cement. The experimental samples were tested at different temperatures of 110, 130 and 150 °C using a gas pressure of 1000 psi. The volume of liquid filtrate collected was measured in milliliters (mL) at 30 min after the test begins. The results show that additional of NS, NT and NF as single type of nanoparticles help control fluid loss from the cement slurry, and its performance varies with temperature and the dosage of nanoparticles. The use NS at 3% provided the best performance in controlling fluid loss compared to all of the results by reducing fluid up to 68%. When combined effect of nanoparticles was tested, fluid loss control was also improved. The use of NST at...

The nanoparticles were selected by weight of cement at proportions equivalent to 1, 2, 3 and 4%. The findings demonstrated that nanoparticles significantly increased the shear bond strength, and the strength increase was dependent on the nanoparticle types, dosage and curing period of the specimens. Due to effective pozzolanic activity, nano-SiO2 provided higher shear bond strength compared to nano-TiO2. The specimens containing 3% nano-SiO2 cured for 28 days displayed the utmost shear bond strength results (0.553 MPa). The optimal replacement dosage was 3% for all nanoparticles. The particle type did not affect the optimum nanoparticles replacement content. To examine the influence of nanoparticles on cement-formation bonding, a Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD), and thermogravimetric tech...

The nanoparticle contents were chosen at proportions corresponding to 1, 2, 3 and 4% based on the weight of cement. The experimental specimens were tested at three various temperatures of 70, 80 and 90 °C using a gas pressure of 1000 psi. The quantity of water filtrate collected was measured in milliliter (mL) at 30 min after the test begins. The results consistently indicate that an additional of NS, NT and NA particles independently, reduced the loss of liquid in cement, and its performance varies with temperature and the nanoparticle dosages. The 3% NS usage delivered strong evidence in lessening fluid loss compared to the other results by reducing the loss up to 72%. When collective impact of nanomaterials was determined, the fluid retainment was also improved. The replacement of 4% NST redu...

The cements are Classes G and H Portland well cements. The cement-formation interface bonding mechanism is a combination of the mechanical indentation of the cement hydrates that interlock to the formation surface and the chemical reactions that occur between the cement slurry and constituents of the rock grains. Mechanical indentation occurs as the hydration products epitaxially grow at the formation surface. The degree to which each of these processes accounts for the formation of the bond is unknown. Here we provide a review of well cement and cement-formation bonds and a discussion of the possible factors that are proposed to influence the microstructural, chemical, and mineralogical properties at the cement-formation interface. In addition, we present some findings about how these factors affect ...
