Jill R. Haizlip – President

Principal Geochemist

Ms. Haizlip has over 30 years of professional experience in the fields of geothermal resource evaluation, geology and hydrogeochemistry applied to a variety of geothermal exploration; resource assessment, testing and characterization; and development projects.  After 15 years as a successful Principal Partner of Geologica, Inc, Ms. Haizlip founded Geologica Geothermal Group in late 2014 in order to continue and expand on the success and capabilities of the Geologica Geothermal Team.  Her expertise in chemistry of geothermal fluids is applied to geothermal resource development in: reservoir characterization and temperatures, non-condensable gases, scaling and corrosion, hydrogen sulfide abatement, steam treatment and other geochemical considerations.  She has worked extensively with multi-disciplinary teams to develop conceptual and numerical models of geothermal systems as a basis for geothermal development planning and decision making and has managed comprehensive geothermal resource development projects.  Ms. Haizlip has extensive experience working on development of geothermal systems worldwide including Djibouti, Indonesia, Kenya, Zambia, Turkey, Caribbean; as well as The Geysers, the Salton Sea, Nevada and other geothermal resources in the Western US.

Amanda Fishbin

Staff Geologist

Ms. Fishbin first joined Geologica Geothermal Group in 2016 as a Staff Geologist after receiving a Bachelor’s Degree from Middlebury College in Geology and a minor in Environmental Studies.  She has provided resource analysis on a wide variety of geothermal systems, primarily through the analysis of geothermal fluid and steam chemistry, geologic interpretation, and computer-based GIS mapping.  She has also provided assistance with reservoir data collection and well testing.

Colin Carver

Staff Geochemist

Mr. Carver has been a staff geochemist with Geologica since late 2017.  Mr. Carver joined Geologica after receiving a B.A. in Chemistry and Environmental Studies from Lewis & Clark College in Portland, OR. Since joining, he has been able to support Geologica’s work in the geochemical evaluation of numerous resources including feasibility studies, resource modeling, and modeling the chemistry of produced fluids.  This work has been performed for both volcanic-hosted and spreading center geothermal systems.  Additionally, Mr. Carver has experience in well testing and field sampling of produced and naturally occurring geothermal fluids.

Leland Davis – Vice President, Operations

Senior Geoscientist

Mr. Davis is the Vice President of Operations and a Sr. Geoscientist with more than 10 years’ experience in the geothermal and environmental remediation industries.  Mr. Davis first joined Geologica, Inc as a Staff Geoscientist in early 2008 after receiving his Bachelor’s Degree from Middlebury College in Environmental Studies and a minor in Geology.  In late 2014, Mr. Davis joined Ms. Haizlip in forming Geologica Geothermal Group, first as Operations Manager and then Vice President of Operations.  Since joining the Geologica team he has focused his professional time working on the exploration and development of geothermal resources, and occasionally, environmental remediation activities.  His primary expertise is in well test planning, implementation, and evaluation.  He specializes in reservoir data collection and resource analysis including computer-based GIS mapping and conceptual modelling.  He is experienced in both ArcGIS and Rockworks software packages.  He has provided key technical support on geothermal resource assessments, feasibility studies, and wellfield management, as well as planning and execution related to well testing, resource data collection, and environmental compliance.  His broad work experience across multiple disciplines in 10+ years with Geologica provides a practical understanding of all facets of geothermal development including geology, geophysics, geochemistry, conceptual modeling, well targeting and design, reservoir engineering, and power plant design.

Nicholas Hinz

Senior Geologist

Mr. Hinz has 20 years of field-based experience with structural geology and geothermal projects located throughout North America, East Africa, Turkey, Asia, and the Caribbean. Mr. Hinz joins the Geologica Team after more than 10 years as a Research Associate at University of Nevada, Reno and the Great Basin Center for Geothermal Energy.  His past industry experiences have included broad regional assessments and evaluations of individual resources, including both volcano-hosted and fault-hosted resources.  He specializes in detailed geologic mapping and stress calculations for the purpose of characterizing fracture permeability, refining conceptual models, and well targeting.  Mr. Hinz has completed projects in a variety of environments and geologic settings including volcanic arcs, rifts, and along continental strike-slip fault zones. He has published extensively on geologic and geothermal topics, frequently leads field trips for professional organizations and assists with geothermal training workshops.

Gabe Matson

Project Geoscientist
Mr. Matson has been with Geologica Geothermal Group since September 2018 and has been working in the geoscience field for the past six years. With his background in geology, geophysics, and mathematics, Mr. Matson specializes in support for geothermal exploration and resource assessment projects including developing site conceptual models, geophysical data processing and analysis, and computer-based mapping. He utilizes such software as ArcGIS, Rockworks, Geotools, and Python. Additionally, Mr. Matson has field experience in potential field (gravity and magnetics) mapping, magnetotellurics, geologic mapping, and sampling

Jesse Turk

Staff Field Geologist
Mr. Turk has over seven years of experience as a geologist working in the geothermal and energy industries throughout the country. Mr. Turk holds a Bachelor’s Degree in Geology from the University of Pittsburgh and joins the Geologica Team after receiving a Post Graduate Certificate from the University of Auckland in Geothermal Energy Technology. During his post graduate studies, he received a First in Course Award for his Geothermal Project paper. He has experience in well targeting, field mapping, conceptual modeling, resource capacity estimation, wellsite geology, site management, well testing, geophysical surveying, GIS mapping, fluid sampling, and geochemical evaluations. He has published in geothermal conferences and taught wellsite personnel geothermal topics.

Dr. Sabodh Garg, Vice President, Reservoir Engineering

Principal Reservoir Engineer

Dr. Sabodh Garg joins the Geologica Team in 2019 as vice president for reservoir engineering and Principal Reservoir Engineer at Geologica. He has collaborated with Geologica on numerous projects over the last 10 years through his previous position as program manager of resource technology for Leidos and Science Applications International Corporation – SAIC. He has been an active participant in geothermal R&D since the mid-1970’s and specializes in geothermal reservoir engineering, geophysical survey interpretation, resource assessment, and development planning. He has carried out technical studies in geothermal reservoir mechanics, pressure transient analysis, multi-phase non-isothermal flow, rock mechanics, and the behavior of geopressured reservoirs. Dr. Garg has served on numerous geothermal and energy-related boards and panels, including Geothermics, Energy Sources, U.S. Academy of Sciences, and DOE review panels, and is recipient of the GRC Special Achievement Award (2001), the GRC 2003 Joseph W.
