Book excerpt: The objective of this Recommended Practice (RP) is to provide a basic understanding of and guidance about drilling fluid rheology and hydraulics, and their application to drilling operations. For this RP, rheology is the study of flow characteristics of a drilling fluid and how these characteristics affect movement of the fluid. Specific measurements are made on a fluid to determine rheological parameters under a variety of conditions. From this information the circulating system can be designed or evaluated regarding how it will accomplish certain desired objectives.

This book was released on 2002 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The hydraulic calculation requires the selection of a best fit model from some models used in petroleum industry. Especially, at low shear rate. This study is based on the data taken from ten wells to evaluate five models- Bingham plastic, Power Law, Casson, Herschel-Bulkley, and Robertson-Stiff for hydraulic optimization. In the course of optimizing, statistical method was used to evaluate all the data using linear regression and least square methods. Calculations were made to determine the rheological parameters, correlation coefficients and relative errors. Comparison was also made to the correlation coefficients and relative errors for selecting the best model for optimizing the hydraulics of specific drilling fluids. In order to verify the optimized results, the pressure losses both inside the drillpipe and the annulus and the Equivalent Circulating Density (ECD) were calculated by using these five models. Data obtained from Herschel-Bulkley model presented the most accurate results"--Leaf iii.

This book was released on 2011-09-29 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: The petroleum industry in general has been dominated by engineers and production specialists. The upstream segment of the industry is dominated by drilling/completion engineers. Usually, neither of those disciplines have a great deal of training in the chemistry aspects of drilling and completing a well prior to its going on production. The chemistry of drilling fluids and completion fluids have a profound effect on the success of a well. For example, historically the drilling fluid costs to drill a well have averaged around 7% of the overall cost of the well, before completion. The successful delivery of up to 100% of that wellbore, in many cases may be attributable to the fluid used. Considered the "bible" of the industry, Composition and Properties of Drilling and Completion Fluids, first written by Walter Rogers in 1948, and updated on a regular basis thereafter, is a key tool to achieving successful delivery of the wellbore. In its Sixth Edition, Composition and Properties of Drilling and Completion Fluids has been updated and revised to incorporate new information on technology, economic, and political issues that have impacted the use of fluids to drill and complete oil and gas wells. With updated content on Completion Fluids and Reservoir Drilling Fluids, Health, Safety & Environment, Drilling Fluid Systems and Products, new fluid systems and additives from both chemical and engineering perspectives, Wellbore Stability, adding the new R&D on water-based muds, and with increased content on Equipment and Procedures for Evaluating Drilling Fluid Performance in light of the advent of digital technology and better manufacturing techniques, Composition and Properties of Drilling and Completion Fluids has been thoroughly updated to meet the drilling and completion engineer's needs. Explains a myriad of new products and fluid systems Cover the newest API/SI standards New R&D on water-based muds New emphases on Health, Safety & Environment New Chapter on waste management and disposal

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Designing a fit-for-purpose drilling fluid for high-pressure, high-temperature (HP/HT) operations is one of the greatest technological challenges facing the oil and gas industry today. Typically, a drilling fluid is subjected to increasing temperature and pressure with depth. While higher temperature decreases the drilling fluid0́9s viscosity due to thermal expansion, increased pressure increases its viscosity by compression. Under these extreme conditions, well control issues become more complicated and can easily be masked by methane and hydrogen sulfide solubility in oil-base fluids frequently used in HP/HT operations. Also current logging tools are at best not reliable since the anticipated bottom-hole temperature is often well above their operating limit. The Literature shows limited experimental data on drilling fluid properties beyond 350°F and 20,000 psig. The practice of extrapolation of fluid properties at some moderate level to extreme-HP/HT (XHP/HT) conditions is obsolete and could result in significant inaccuracies in hydraulics models. This research is focused on developing a methodology for testing drilling fluids at XHP/HT conditions using an automated viscometer. This state-of-the-art viscometer is capable of accurately measuring drilling fluids properties up to 600°F and 40,000 psig. A series of factorial experiments were performed on typical XHP/HT oil-based drilling fluids to investigate their change in rheology at these extreme conditions (200 to 600°F and 15,000 to 40,000 psig). Detailed statistical analyses involving: analysis of variance, hypothesis testing, evaluation of residuals and multiple linear regression are implemented using data from the laboratory experiments. I have developed the FluidStats program as an effective statistical tool for characterizing drilling fluids at XHP/HT conditions using factorial experiments. Results from the experiments show that different drilling fluids disintegrate at different temperatures depending on their composition (i.e. weighting agent, additives, oil/water ratio etc). The combined pressure-temperature effect on viscosity is complex. At high thresholds, the temperature effect is observed to be more dominant while the pressure effect is more pronounced at low temperatures. This research is vital because statistics show that well control incident rates for non- HP/HT wells range between 4% to 5% whereas for HP/HT wells, it is as high as 100% to 200%. It is pertinent to note that over 50% of the world0́9s proven oil and gas reserves lie below 14,000 ft subsea according to the Minerals Management Service (MMS). Thus drilling in HP/HT environment is fast becoming a common place especially in the Gulf of Mexico (GOM) where HP/HT resistant drilling fluids are increasingly being used to ensure safe and successful operations.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pressure management and hole cleaning are fundamental aspects of a successful drilling operation. Despite a plethora of research articles, contradictory results continue to be reported in the literature. The variables involved have been extensively researched but rheology continues to suffer from severe oversimplifications. Few studies go beyond the canonical time-independent characterization and even fewer consider the addition of drill cuttings and thermal effects. The composition of drilling fluids makes them a typical case of complex fluids such that the rheology is dependent on shear rate and flow history. Complex fluids exhibit several peculiar rheological features that are augmented in a drilling environment. The present work investigates the interplay between complex rheology and drilling hydraulics; the latter here refers to bottomhole pressure and cuttings transport. In this work, rheological algorithms are developed to characterize complex rheology. The multiphase mixture of fluid and cuttings is modeled as thixotropic viscoplastic (TVP) suspension. It is observed that high yield stress and flow rate do not guarantee efficient hole cleaning. In most cases, high yield stress deteriorates cuttings transport. A large stress overshoot improves cuttings transport, though the distinction between the static and dynamic yield stresses diminishes as particle concentration increases. Since viscosity lags shear rate changes in thixotropic flows, pressure fluctuates and swirling viscosity profiles are generated, giving rise to localized turbulence and Taylor vortices even at low velocities. Moreover, cuttings transport varies as a power-law function of particle shape, size, and flow rate. Under a geothermal gradient, high-temperature regions develop near the inner pipe as fluid moves upwards. Temperature has a diverse effect on rheology and temperature-viscosity profiles are often non-monotonic. For such fluids, the pressure profile is highly non-linear as most of the frictional losses occur near the bottomhole. Fluids with non-monotonic temperature-viscosity profiles yield better cuttings transport but at the cost of higher pressure. Modeling the time-dependent rheology of drilling fluids while studying drilling hydraulics helps in addressing several contradictions found in the literature. It is recommended that the experimental and computational efforts focused on drilling hydraulics should characterize complex rheology for a better understanding of drilling hydraulics
