New Sensor Development Helps Optimise Production Logging Data Acquisition in Horizontal Wells

As horizontal wells become increasingly common, the need to make measurements to optimise well health and manage the reservoir also increases. Production logging in horizontal wells with multiphase flow present data acquisition challenges in the form of both conveyance method and sensor selection.

In this paper we present an approach to logging a horizontal well using new generation array sensors. The well was cased and perforated with high water cut and sand production.

Logging while tractoring a combination of conventional (centralised) and array sensors provided a good quality data set that enabled successful identification and shut off of sand and water.

The use of a new impeller design in a minispinner array helped overcome the challenges sand production posed in the well. Smaller minispinner thresholds improved the velocity profile allowing us to identify water recirculation at very low rates.

An array resistance measurement provided an estimate of water holdup.

Tool rotation proved a tremendous benefit for array sensors run in this harsh environment. Tool rotation helped keep the sensors free from debris while the traditional centralised spinner show an increased tendency for jamming when intersecting sand dunes or restrictions along the well trajectory. In addition, the rotating array sensors provide better circumferential coverage in the well.

A sand detection instrument was used in combination with the production logging string. The instrument is fully combinable with the production logging string and simultaneous data acquisition makes it easy to integrate all sensors allowing a robust interpretation of sand influx and water salinity.

This paper focuses on the acquisition of new generation array data to help meet the well intervention objectives leading to a commercial and technically successful outcome. It identifies the strengths and gaps of current technology relative to existing challenges in horizontal wells and the need to move to array measurements.

Well Testing for Reservoir Description

Meeting info

AFES Seminar - Aberdeen , 6th April 2011

AFES are happy to announce that Patrick Corbett, Hamidreza Hamdi and Alireza Kazemi from Heriot-Watt University will be conducting a half day seminar titled "Well Testing for Reservoir Description", which will be held at the Station Hotel, Aberdeen on Wednesday 6th April.

The seminar will provide an introduction to well testing, followed by a series of interesting presentations to the common petrophysicist / geoscientist / reservoir engineer on topics described in the attached programme. The day will close with a discussion session followed by drinks and canapés.

If you wish to attend to the seminar, please email Callum J. Aderson. The cost of the seminar will be £50 paid on cash on the same day.

Real-time Integration of Reservoir Modeling and Formation Testing

Meeting info

AFES Evening Lecture - 9th March - Station Hotel - 6pm

Held by Adriaan Gisolf, Reservoir Domain Champion, Schlumberger

Abstract

The increasing complexities of newly discovered reservoirs coupled with the increasing cost of field development mandate significantly improved and timely work flows for reservoir evaluation. In this presentation a workflow is demonstrated where a fluids model is used to predict data for a wireline formation sampling and testing tool (WFT), with emphasis on downhole fluid analysis (DFA). The fluid model incorporates “conventional” Equation of State modeling as well as breakthroughs in asphaltene science to describe the heavy-end distributions of reservoir fluids. In this process, current reservoir understanding is tested by direct measurement in real time.
