Horizontal Production Logging – Maximising production logging in horizontal wells through the use of Sondex Multiple Array Production Suites. Aaron Adamczyk, Well Intervention OTC Houston May 2015 Introduction to Expro Global market leader in well flow management Market leading global provider of highly specialised well flow management services to the oil and gas industry. Specific focus on offshore, deep water and other technically challenging environments with high barriers to entry. Offer a range of mission critical services designed to measure, improve, control and process flow from high value oil and gas wells: • Well test and appraisal • Subsea, completion and intervention services • Production services • Capabilities span the full life cycle of oil and gas field from exploration to abandonment Our vision is to be the market leader in well flow management, using the industry’s best people, to deliver the highest standards of safety, quality and personalised customer service. © Copyright Expro 2015 Presentation outline • Products and services • Horizontal production logging • Data analysis centre • Q&A ©Copyright Expro 2015 Products & services Well Intervention Well Testing & commissioning • • • • • • • • • • • • • • Kinley calipers Kinley power tools Downhole video Production logging Memory gauges Electronic calipers Metal thickness tools Tubing Conveyed Perforating (TCP) Toe sleeves Packers & service tools Well testing Flowback & frac stacks Chokes systems Flarestacks ©Copyright Expro 2015 Horizontal production logging MAPS MAPS Multiple Array Production Suite ©Copyright Expro 2015 Horizontal production logging Horizontal sections are never drilled perfectly ©Copyright Expro 2015 Horizontal production logging Multiple fluid and hydrocarbon phases in a horizontal well • Lighter hydrocarbons producing on high side • Heavier water recirculating on low side ©Copyright Expro 2015 Horizontal production logging Multiple fluid and hydrocarbon phases in a horizontal well • Lighter hydrocarbons producing on high side • Heavier water also producing on low side ©Copyright Expro 2015 Horizontal production logging Understanding flow profiles Producing gas Producing water Flowing oil Stagnant water ©Copyright Expro 2015 Horizontal production logging In oil & gas wells numerous flow regimes are possible Even with small deviations, a light phase may separate to the high side of the well ©Copyright Expro 2015 Horizontal production logging Center mounted production logging tools Tools positioned in the center of a well may miss oil or gas flowing on the high side or water on the low side of the pipe ©Copyright Expro 2015 Horizontal production logging MAPS – key benefits • Identify oil & gas production and locate water entry points • Operate in all well inclinations from vertical to horizontal • MAPS combines: • Spinner Array Tool (SAT) • Capacitance Array Tool (CAT) • Resistance Array Tool (RAT) • Multiple center mounted sensors • Primary goal is to measure phase hold-ups and velocities • Multiple sensors provide user configurable 3D visualization of multiphase flow with MAP view • Memory and real time logging • Multiple conveyance options ©Copyright Expro 2015 Horizontal production logging MAPS is suitable for wells where phase separation occurs, from near vertical all the way to fully horizontal One, two or three of the MAPS tools may be run with a standard Sondex Ultrawire Production Logging string MAPS may be deployed in surface read out or memory mode Bow springs open to 7” maximum ©Copyright Expro 2015 Horizontal production logging MAPS : Capacitance Array Tool (CAT) • 12 miniature sensors mounted on bow springs • Specially developed to measure the capacitance of surrounding fluid to identify phase type ©Copyright Expro 2015 Horizontal production logging MAPS: Resistance Array Tool (RAT) • 12 miniature sensors mounted on bow springs • Specially developed to measure the electrical resistance of surrounding fluid ©Copyright Expro 2015 Horizontal production logging MAPS : Spinner Array Tool (SAT) • 6 miniature flowmeters offset mounted on bow springs • Measure the velocity of surrounding fluid ©Copyright Expro 2015 Horizontal production logging Measurements recorded in a single plane across the diameter of the well-bore rather than along it Results in an accurate cross-sectional plot of fluid phases Combining data from the Spinner Array Tool, Capacitance Array Tool and the Resistance Array Tool, enables quantitative estimates of the volumetric flow rate for each phase ©Copyright Expro 2015 Horizontal production logging As seen with SAT and CAT data Conventional spinner showing missed data ©Copyright Expro 2015 Horizontal production logging Increasing velocity Increasing liquid holdup ©Copyright Expro 2015 Horizontal production logging MAPS tool deployment Flow regime has chance to recover between one tool and the next so each tools measurement is unaffected by previous > 4 ft SAT RAT CAT ©Copyright Expro 2015 Data analysis center Log interpretation ©Copyright Expro 2015 Data analysis center Log interpretation ©Copyright Expro 2015 Horizontal production logging Flow profiles Gas Oil Water ©Copyright Expro 2015 Horizontal production logging MAPS has the ability to see small hold-ups (RAT and CAT) Gas Oil Water ©Copyright Expro 2015 Thank you: any questions?
