Disposal/Injection Crisis – A Step by Step Evaluation Method to Determine if a Well Is at the End of Life When It Stops Taking Fluid.

Proper evaluation and management of isposal and injection wells are critical to ensuring reliable, consistent performance and long-term injection. Variations in the quality of produced water over the life of a well greatly impact variations in disposal fluids. Planning ahead and following a step-by-step evaluation method will help diffuse a crisis and determine if the well is at the end of life. This method provides a concise evaluation plan to determine the need for increasing injection pressures (when allowed) to maintain injection rates.
Client experiences demonstrate injection water quality greatly influences economics. Indications of an injection well in trouble (such as increases in injection pressure required for lower injection rates) often lead to higher electric cost, a possible re-frac or even drilling a new well.
Today we will discuss five basic evaluation steps in detail. It should be noted, a failure at any point in the process should result in an economic review to determine if the injection well is at the fiscal end of life. A cursory geological and reservoir re-evaluation is the least costly and should be the first step taken to see if the well is near end of life. This re-evaluation is closely followed by a detailed water study, in conjunction with an injectability evaluation, surface equipment review and finally a re-frac proposal if indicated.
Designing, implementing, and maintaining a consistent management program for disposal and injection wells will ensure injection can be sustained long term.
Business Development, Technical Advisor, Weatherford Laboratories, Houston, Texas
Summary: Derrick has fifteen years of experience in the industry, all with Weatherford Labs. He began his career in oil and gas with the WFT Geochemistry Lab Group, followed by six years in project management for reservoir rock and fluid services and most recently in Technical Advising and Business Development for US and Latin America. A strong background in geochemistry, petrology, petrophysics, geomechanics, and special core analysis serves clients in designing comprehensive core and fluid analysis programs for formation evaluation in both conventional and unconventional reservoirs with extensive experience in the Permian Basin.
Currently, Derrick is highly involved in the development and implementation of Weatherford Labs’, full service Oil Field services Water Laboratory focusing on compositions of fresh, produced, injection waters, inhibitor detections, water sourcing, flow assurance and corrosion, water injection/treatment efficiency and many more water related oilfield issues. He is also focused on developing new revenue streams through product research and market analysis in order to drive technological advances and maintain the highest standards and innovations expected from our clients.
Derrick attended the University of Western Ontario before moving back to Houston with a laboratory and data management position with the legacy WFT Labs, Humble Geochemical Services.
Patricia (Patty) DuBois
Weatherford Laboratories, Houston, Texas
Summary: Patty is a Geologist with over twenty years of operations experience in conventional and unconventional oil and gas operations including waterflood and water disposal projects. Recently she mentored field development, cross-functional teams and interns (both geologist and non-geologist) with drilling wells, reserve documentation, mapping, Salt water disposal (SWD) and Acid Gas Injection (AGI) evaluation, and behind pipe pay for both shallow and deep reservoirs.
As a cross-functional lead and mentor, she used data mining and multiple produced water analysis to investigate and identify the source of produced water in high water cut areas. Using precise water analysis results to identify scale trends, her team generated scale prediction maps resulting in more precise chemical treatments and lowering OPEX. A companion project examined oil and gas analysis to identify H2S and CO2 sources, trends and generate prediction maps for fields and ultimately leading to a $200 million cost savings. She has been an expert witness for SWD, AGI, and commingling including assisting clients to develop state required documentation.
Patty has a MS in Geosciences, a BA in Earth and Planetary Sciences and BS in Systems and Data Processing and is an author on numerous technical presentations.
