SUMMARY:Register Now for the ICOTA USA Lunch & Learn with OXY March 3, 2023 – Houston
DESCRIPTION:ICOTA USA Lunch & Learn with OXY\nUtilizing Low Density Mud Systems to Improve Operational Efficiency for Post Frac Cleanout of Unconventional Wells in Depleted Areas \nby David Peurifoy, Engineering Advisor, OXY\nAbstract\nDue to recent advancements in horizontal drilling and completions technology, wells in some basins are now being completed in areas where conventional production has existed for 50+ years. This paper will focus on the Midland Basin, where wells in the Spraberry, Dean, and Wolfcamp formations have been produced since the 1960s and earlier in some cases. As a result, current unconventional wells in these formations will invariably deal with depletion. In the past, freshwater consisting of friction reducer and a foaming agent, along with nitrogen, was used to lighten cleanout fluids to a fluid density that allows circulation of these wells. The use of nitrogen, while necessary, can lead to variable fluid quality, increase cleanout times, add expense, and ultimately reduce time-to-market for these wells.\nLightweight mud systems (LMS) are not new to the oilfield but relatively new to post frac cleanout operations applications. The system consists of a proprietary water-based mud additive that reduces mud density by creating microbubbles that encapsulate air in a multi-layer shell. Using this technology, fluid weights can be reduced by up to 1.9 ppg from the original base weight. The base fluid for the LMS may be freshwater, produced water, or brine. The fluids possess a low shear rate viscosity that allows good hole cleaning without risking formation invasion. The system may be used with nitrogen if needed for extreme cases. No degradation of mud motor performance has been observed when using the LMS. This paper will offer 3 case studies where the LMS provided operational and economic benefit in post frac cleanout operations.\nAll case studies in this paper will show that the application of LMS technology has benefitted post frac cleanouts in low-pressure unconventional wells by the reduction/ elimination of nitrogen and acceleration of wells to production.\nRegistration\nRegister to attend by clicking the “Reserve a Spot” button above or you can contact us at 936-520-1549 or at ababin@icota.com for a different payment method or to reserve your spot and pay onsite.
