Developing smart drilling fluids that can adapt to harsh downhole conditions with extreme pressures and temperatures over 7,000 meters deep is challenging. Drilling fluid must maintain stable density and rheology at these conditions while transporting cuttings and cooling drill bits. Improved rheological models and hydraulics modeling are needed to better predict downhole pressure and optimize fluid properties. Additives also need to be developed that can withstand the hostile environments encountered during deep drilling.

This summarizes a field implementation of a novel solids-free fluid loss control system during overbalanced workover operations in southern Argentina. The system uses a water-soluble polymer that decreases formation permeability to aqueous fluids, limiting fluid loss. It was applied before cleanout treatments on two wells experiencing significant fluid losses. For both wells, the system successfully reduced losses to an acceptable level, allowing the cleanout treatments to be performed effectively with no further circulation issues. The operator has now used this system for over 200 treatments with good results in controlling fluid loss during workover operations in the area.

The document summarizes the efforts of an operator in Argentina to reduce freshwater consumption in hydraulic fracturing operations by using produced water as the base fluid. Tests were conducted on various sources of produced water from 2005-2010 to evaluate their suitability. Initial tests in 2005 identified sources that maintained adequate fracturing fluid viscosity over time. Subsequent years saw a gradual increase in produced water usage, reaching 54.8% of the total water volume used in 2010 and reducing freshwater consumption by 5.7 million gallons. The methodology helped establish reliable sources and procedures for using produced water while maintaining fracturing treatment performance.

This document summarizes the use of a packerless, multistage fracture stimulation method called pinpoint fracturing (PPF) in Argentina. Key points:
1) PPF has been used to complete 22 wells with 193 fractures since 2006, allowing more selective stimulation and aggressive fracturing treatments.
2) The method uses coiled tubing to hydrajet perforate intervals and pump fracturing fluid down the annulus, isolating stages with sand or bridge plugs.
3) A case study describes applying PPF across 9 wells with 90 stages, reducing completion times compared to conventional methods using packers.

This paper discusses optimization of hydrocarbon production in the Cerro Dragon oilfield in Argentina using latest formation evaluation and perforating technologies. It summarizes how nuclear magnetic resonance (NMR) logging helped identify different hydrocarbon types in reservoirs that conventional logs could not distinguish. A propellant-assisted perforating (PAP) method was proposed to optimize well productivity while maintaining safety. The PAP method uses oxidizer to create high pressures and mild fracturing near the wellbore. The paper focuses on applications of PAP in the San Jorge basin, including enhancing connectivity beyond damaged zones and near water contacts where hydraulic fracturing is not feasible.

This document summarizes the use of liquid curable resin (LCR) systems to control proppant flowback in hydraulic fracturing operations in Argentina. Various operators applied LCR either during initial fracturing treatments by coating proppant on-site, or as remedial treatments by injecting resin into existing fractures. LCR treatments helped stop proppant flowback while maintaining production rates, reducing cleanout costs compared to untreated wells. Lessons showed resin concentration and additive selection are important to maximize proppant pack strength and conductivity. Field results demonstrated LCR treatments effectively control solids flowback to optimize well productivity.

This document discusses dual-frequency resistivity logging, a well logging method that uses different current frequencies to measure formation resistivity. It introduces the principle that reservoirs exhibit a dispersion phenomenon where resistivity values differ between low and high frequencies due to the capacitive effect of oil. This allows distinguishing oil and water layers based on the ratio of low to high frequency resistivity. The document provides an example application in a Chinese oil field where dual-frequency logging accurately identified oil and water zones. It concludes that dual-frequency logging has good adaptability to different lithologies and salinities and is a promising technique for reservoir evaluation.

1) The document analyzes oil-water layer recognition and distribution of PI reservoirs in the G region based on core data, oil testing, and well logging.
2) An oil-water layer logging interpretation chart is established using resistivity logs to identify 5 types of vertical oil-water distributions in single wells and the overall horizontal zoning of distributions across the region.
3) The distributions are complex due to structural, sedimentary, and diagenetic factors but generally include pure oil, oil-water, and pure water layers that vary based on position within anticlines, synclines, and slopes.
15 Outcome of the Repoperm Project
The Repoperm project studied the mechanical and hydraulic behavior of compacting crushed salt backfill at low porosities. It found that:
1) Measurement of properties like permeability and constitutive relationships for two-phase flow are possible down to gas permeabilities of 10-15 m2.
2) Presently used models have limits and material parameters depend on the specific test, so predictive capability needs improving.
3) Further research is needed to fully characterize hydro-mechanical behavior, understand permeability under unsaturated conditions, and reconcile results from different test types.

This paper discusses an integrated approach to characterizing water saturation in a low-resistivity carbonate reservoir in Abu Dhabi. Traditional resistivity-based analyses overestimated water saturation in this reservoir. The integrated approach combined resistivity logs, core analysis including NMR and capillary pressure tests, and production test data. It identified microporosity from thin sections and NMR as contributing to the low resistivity pay. The combination of multiple data sources reduced uncertainty and improved understanding of reservoir properties, saturation estimates, and reserves calculations compared to resistivity-based analyses alone.

This document summarizes a field study on using a liquid curable resin system to prevent proppant and formation sand production in high water cut, heavy oil wells in Argentina. The study involved hydraulic fracturing treatments using proppant coated with a low-temperature curable epoxy resin. Field results showed that the resin coating effectively stopped proppant and formation sand from being produced back while maintaining production rates. The resin treatment provided a reliable and cost-effective alternative to sand control screens for controlling solid flowback in marginal reservoirs.

This document summarizes a conference on tight shales held in Warsaw, Poland in March 2011. It discusses how tight shales are not all the same and differ in their reservoir quality. Methods for characterizing and analyzing shale such as micro-structure observations, core analysis, well logs, and hydraulic fracturing are presented. The heterogeneity and natural fractures within shales are shown to create complex hydraulic fractures. Different conceptual fracture models are evaluated using reservoir simulation to demonstrate how fracture geometry impacts production outcomes. While knowledge is advancing, the document concludes that understanding the rock properties remains important for improving shale reservoir performance and lowering technical risk.

This document summarizes the results of using coiled tubing and a true fluidic oscillator tool to stimulate 20 low production wells in the San Jorge Gulf area of Argentina. Deposits of paraffin, asphaltene, and calcium carbonate were causing damage to the wells. The fluidic oscillator tool generated pressure waves of 300-600 Hz to weaken and remove near-wellbore damage. Treatments of solvent followed by acid were pumped selectively into zones. The approach achieved production increases in oil rates of 30-365% and total fluid rates in 75% of wells. It provides a more cost-effective alternative to conventional well interventions.

Does Heavy Oil Recovery Need Steam?
Heavy Oil recovery traditionally starts with depletion drive and (natural) waterdrive with very low recoveries as a result. As EOR technique, steam injection has been matured since the 1950s using CSS (cyclic steam stimulation), steam drive or steam flooding, and SAGD (steam assisted gravity drainage). The high energy cost of heating up the oil bearing formation to steam temperature and the associated high CO2 footprint make steam based technology less attractive today and many companies in the industry have been actively trying to find alternatives or improvements. As a result there are now many more energy efficient recovery technologies that can unlock heavy oil resources compared with only a decade ago. This presentation will discuss breakthrough alternatives to steam based recovery as well as incremental improvement options to steam injection techniques. The key message is the importance to consider these techniques because steam injection is costly and has a high CO2 footprint
Johan van Dorp holds an MSc in Experimental Physics from Utrecht University and joined Shell in 1981. He has served on several international assignments, mainly in petroleum and reservoir engineering roles. He recently led the extra heavy-oil research team at the Shell Technology Centre in Calgary, focusing on improved in-situ heavy-oil recovery technologies. Van Dorp also was Shell Group Principal Technical Expert in Thermal EOR and has been involved with most thermal projects in Shell throughout the world, including in California, Oman, the Netherlands, and Canada. He retired from Shell after more than 35 years in Oct 2016. Van Dorp (co-)authored 13 SPE papers on diverse subjects.

Challenges Drill Fluids
- 1. DRILLING FLUID CHALLENGES FOR OIL-WELL DEEP DRILLING Vassilios C. KELESSIDIS vaskel1@hotmail.com sk l1@h tm il m Technical University of Crete Mineral Resources Engineering SGEM 2009 Albena, June 14-19, 2009
- 2. Research aim Develop smart drilling fluids Adaptable to harsh conditions Have available t h i H il bl techniques for optimal sf ti l measurements of fluid properties, particularly rheology Develop hydraulics models for pressure drop prediction along the wellbore Better understanding efficient cuttings transport in a multiphase environment 2
- 3. The problem Drilling depths, total (>7000 m) and water (~ 3000m) depths, are ever increasing depths High pressures (>2000 bar) and high temperatures (>3000C) are encountered Narrow pressure tolerances Harder rock is encountered, lower drilling rates Demand for better drilling fluids, avoid p problems -understand behavior in such hostile m environments Hydraulic programs for complex rheology 3
- 4. Deep drilling challenges hard rock - wellbore stability - high P, T 4
- 5. MPD vs Conventional 5
- 6. Drilling fluid challenges ROLE Hydrostatic pressure Cuttings transport Cooling the bit Wellbore stability stab l ty CHALLENGES High T P T,P stable density and rheology Measurements at downhole conditions Predictions of downhole conditions Stability of additives y f Appropriate rheological models 6
