Abstract:

Produced Water Reinjection (PWRI) projects are often characterized by loss of injectivity, which can result from a number of potential factors, some of them interconnected. These include formation properties such as mineralogy, rock properties and formation stress, as well as injection water quality, which is a function of water composition/chemistry, topside separation/treatment and water injection infrastructure. It is commonly the case that identification/analysis of the major issues for a specific field and circumstances are not performed prior to the start of injection, which can result in an incorrect/inapplicable injection strategy/regime, unexpected injectivity loss and expensive remedial equipment acquisition or modification. 

In this talk two field examples are presented in order to illustrate the impact of some of the above factors. The first is a mature onshore PWRI project in Sumatra, where injectivity decline was only observed after several years, seriously affecting the reservoir pressure maintenance program, hence overall oil productivity. In this study, various aspects affecting injectivity are reviewed and a potential mechanism of injectivity decline proposed. The second is a PWRI project for water disposal offshore Brazil, where the operator is evaluating the feasibility of re-injecting untreated produced water. Pre-injection modelling work has identified a clear requirement for produced water treatment and indicated an appropriate lab testing program to complement planned injectivity trials in a potential disposal well. 

The main proposition of this presentation is to highlight the benefits of a comprehensive analysis of potential issues prior to implementing a PWRI project.

Speaker bio:

Dr Rick Lemanczyk has over 45 years’ experience in the Oil & Gas industry, primarily in the area of Production Technology and Optimization. Semi-retired, he is currently an Associate Principal Petroleum Engineer with THREE60 Energy Subsurface and is based in Kuala Lumpur, Malaysia.

Rick’s professional journey began as a wireline engineer with Schlumberger in the Middle East, well stimulation research with Dowell Schlumberger in France and later as Laboratory Manager in Aberdeen. Over the years his journey took him on the roads of Production Optimization, Formation Damage, Artificial Lift (gas lift & ESP design/operations), Sand Management & Control, and Rock & Fluid Mechanics. He has extensive multidisciplinary project management experience, having led subsurface teams on development projects in Indonesia, Thailand, and Malaysia (Sabah). Along the way he has made various forays into the murky waters of Water Injection, managing a team for re-instating water injection on a mature field offshore East Malaysia, led a multidisciplinary water injection/formation damage study for an onshore field in South Sumatra, and more recently was involved in a PWRI feasibility study for water disposal offshore Brazil. 

In addition to his technical activities Rick has been actively involved in professional training throughout his career. He is a member of the Society of Petroleum Engineers (SPE) and has participated in the management of several SPE Advanced Technical Workshops in the Asia Pacific Region. He was nominated to the SPE Distinguished Lecturer program in 2010-2011 on the subject of Gas Lift Optimization and serves on the DL Selection Committee for 2025-26. In 2016 & 2017 he was an Adjunct Professor in the Heriot Watt University Malaysia M.Sc. program in Petroleum Engineering, lecturing on a variety of production technology subjects.
