Case Study

A large US independent operator was using horizontal air-hole drilling technology to drill several laterals off a single pad to maximize production and avoid the added expense of drilling with fuid Lateral azimuth directions were selected based on information gathered from existing vertical producing wells and geologic analysis of the fracture systems Not wanting to load these laterals with fuid the operator was seeking the highest-quality imaging log data to (1) confrm geologic modeling (2) fully interpret the fracture systems encountered (3) distinguish open naturally producing fracture systems from non-productive systems (comparing the images to basic open air-hole hole logging suites and spinner logs) (4) aid in completion and stimulation design and (5) determine location and azimuth of future lateral placements

Before logging horizontally the operator wished to compare the OPTVtrade with a traditional micro-resistivity imaging device using a vertical pilot hole drilled through the target formations Both tools were run over the same intervals and the quality of images compared The operator was satisfed that the OPTV image quality run in air was superior to those obtained by the micro-resistivity device run in fuid especially in identifying the fractures The horizontal project proceeded as designed with the horizontal section drilled and logged on air

Job participants estimated that using the OPTV system to obtain required images from an air-flled borehole yielded savings of 48 hours of rig time $10000 in fuid and removal and $25000 in wireline logging conveyance and interpretation The method also allowed the operator to avoid formation damage and associated risk

Basic Processing

Dip Processing is done via a user friendly interface Features are identifed with customizable user controlled labeling Strike and Dip of the feature is calculated and presented in standard or custom formats

Any geologic feature such as bedding vugs fractures clasts etc may be chosen for processing Feature thickness can be calculated Picks can be edited added or deleted at anytime Processing is saved and can be revisited and revised at your convenience

Basic Interpretation

Once features have been chosen and processed a printable log is made The interval processed can be of any length desired Any or all of the views and plots can be chosen Core View Flat Image View Arrow Plot 2 Stick Plots (different angles) Labeling and comments chosen in Processing Borehole Deviation plot log are made and can be printed in JPG BMP or PDF format
