For members who are consultants, SIPES maintains an online Referral System for Consultants designed to match consulting members with individuals or companies requiring the services of a qualified earth scientist. Data in the system is updated periodically and includes information about professional specialties and geographic areas of practice. SIPES has developed, in conjunction with the DPA of AAPG, useful professional Model Contracts for Independent Geoscientists. A Model Confidentiality Agreement Form and a Contract for Geoscience Services are now available.
SIPES publishes the SIPES Quarterly, containing informative articles, as well as news of members and information about SIPES Chapter activities. A SIPES Membership Directory is available online to members, and is revised on a quarterly basis. The directory includes telephone numbers, e-mail addresses, and includes member photos and information on each member’s education, professional history, areas of expertise and certification number. It is a useful reference for members when evaluating and hiring earth science consultants. The SIPES Deal Buyer's List is exclusively for members who are interested in viewing prospects developed by fellow SIPES Members.
SIPES Chapters rotate responsibility for co-hosting a National Convention each year. The SIPES Annual Meeting includes a two-day technical session that offers SIPES Members information that is relevant to the independent or consulting earth scientist, as well as field trips and social events. The SIPES Convention also provides a forum to honor members for their dedication and outstanding service to the society. SIPES Members receive discounts on convention and seminar fees.
Through the SIPES Foundation, a charitable and educational organization founded in 1982, members can attend educational seminars and have access to a large earth science Video Film Library. The Foundation also offers members an opportunity for charitable gifting to provide and support programs beneficial to the education and development of earth scientists. The SIPES Foundation also supports geoscience training centers located in SIPES Chapter areas, and awards annual scholarships to outstanding earth science honor students.
SIPES addresses a wide variety of state and federal issues which directly affect the independent earth scientist. Responses to lawmaking and rulemaking are provided to state and national legislative and governmental agencies. As a Cooperating Association with the Independent Petroleum Association of America and as a member of the American Geological Institute’s Governmental Affairs Program, SIPES Members benefit from the direct contacts these groups have with legislators and government agencies in Washington, DC concerning issues affecting the oil and gas industry and the earth sciences.
