Thinking Sideways to The Far East

Blending In The Near Field and Far Field Reservoir Characterization


High Angle and Horizontal Wells (HAHZ) Special Interest Group and Japan Formation Evaluation Society (JFES) committee would like to invite you to join the
2023 HAHZ workshop on 11th 12th September 2023 at the Japan Oil, Gas and Metals National Corporation Technology & Research Center (JOGMEC-TRC), Chiba, Japan.

This workshop is open to all SPWLA, affiliated and non-SPWLA members. We aim to facilitate knowledge sharing and multi-discipline collaboration specific to high angle data acquisition, well placement and evaluations.

HAHZ workshop will be conducted in off-the- record basis with no proceeding publication and no recording to encourage open discussion and sharing of information. We would like to encourage participants and presenters to share their case studies (could include published examples), new methodologies and latest technologies which may or may not yet be ready to officially publish.

Special Interest Group

Mission Statement
Our mission is to create a collaborative forum where Geologists, Geophysicists, Petrophysicists as well as Geomechanical, Reservoir, and Completion Engineers can propose and deliberate solutions to mitigate the challenges in accomplishing the common goal of more accurate formation evaluation in high angle and horizontal wells.  The SIG encourages the integration of all data including core, drilling, logging, surface data, and any other available data to aid in attaining this goal.  The long term benefits of our SIG to the industry will be improved the formation evaluation,  drilling and well placement techniques, more complete reservoir understanding and more effective completion designs in high angle and horizontal wells.
