Material Qualification in Saline Copper Containing Geothermal Water

Product Number: 51319-12862-SG

Author: Ralph Baessler

Publication Date: 2019

$20.00

Since geothermal wells are a feasible energy source to replace fossil fuel supply many technologies have been developed to take advantage of geothermal energy. Nevertheless service conditions in geothermal facilities are due to the chemical composition of hydrothermal fluids and temperatures in many cases extreme in terms of corrosion. Therefore materials selection based on preliminary material qualification is essential to guarantee a secure and reliable operation of the facilities. During operation of a geothermal research facility in Groß Schönebeck copper effects have been found downhole. Occurring mechanisms and measures to prevent copper precipitation or scaling needed to be investigated.This contribution deals with the evaluation of the corrosion behavior of different metals ranging from carbon steel via stainless and duplex steels to titanium in a copper containing artificial geothermal water simulating the conditions in the Northern German Basin.The behavior of carbon duplex stainless steels and titanium in this geothermal fluid obtained by electrochemical measurements and exposure tests will be presented. While carbon steel exhibits coppering and copper precipitation higher alloyed materials show different response to Cu-species in saline geothermal water.Basing on these results the suitability of the investigated materials for use in such conditions will be evaluated.

Material Selection Methodology Using Halite Tendency Indicators for Gas Wells: A Case Study

In gas wells, where a low or unknown amount of the naturally occurring saline formation water is expected to be produced, tubing material selection relies on selecting a fixed dataset of input parameters and extrapolating to the entire well life. This is intended to represent the worst-case scenario; while this can be the case regarding pressure and temperature, the produced water composition as a function of time is less likely to be as reliable. This is because during production, gas can cause water evaporation, leading to a significant increase in the chloride ion concentration compared to the analyzed values – and hence, potentially an unsuitable material selected. To this end, it is important to: (a) ensure that the formation water composition analyzed is correct, (b) that this composition is reconciled to initial reservoir conditions and (c) calculate any evaporation/condensation effects in different sections of the well as a function of production forecasts. This makes it easier to establish operational envelopes that both prevent productivity impairment and provide appropriate thresholds of acceptability for the tubing material selected. This paper describes the methodology applied for tubing material selection for a high temperature-high pressure (HTHP) gas well in the North Sea.

Integrity of materials in Oil & Gas production wells is critical to meet the objectives of design and the lifecycle performance of wells. This is significant value both in economic terms and health safety and environment. Subsurface uncertainties Aging fields EOR activities and also the quality of procured equipment add to the difficulties in preventing equipment failures in wells. Failures that are especially unforeseen or unanticipated provide crucial feedback to operators and lessons to be learnt. It is imperative for operators to learn improve processes and avoid recurrence of failures.Petroleum Development Oman (PDO) as a large operator with more than 10000 wells has gained important experience and lessons from many such failures. This has contributed significantly to improve the company standards material selection reset the operating envelope and procedures enhance surveillance and improve upon quality assurance and control of new equipment.This paper is a compilation of some of the important lessons learnt from such incidents in the recent past. It discusses the operational experience and learning from different subsurface materials from CS to nickel alloys used in different components such as casing tubing packers and X-trees.

Materials Performance in Oxidizing Acid and Corrosive Solution containing Oxidants

Product Number: 51319-12991-SG

Author: Ajit Mishra

Publication Date: 2019

$20.00

Nickel-based alloys containing optimum amounts of chromium (Cr) molybdenum (Mo) and tungsten (W) are widely used in the chemical process industries due to their tolerance of both oxidizing and reducing conditions. In the present study corrosion tests were performed using weight loss and electrochemical techniques for Ni-based CRAs in various corrosive solutions. The motivation of this study is to understand thematerials performance in oxidizing acid (such as nitric acid) and acidic solutions containingoxidants (like ferric ion cupric ion peroxide etc.). An attempt was further made to correlate the corrosion performance of the alloys in individual and mixed acids to their alloying elements and contents.The corrosion data suggest that in oxidizing acid reducing + oxidizing acid and in solutions containing oxidants HASTELLOY® G-35® (UNS N06035) (Ni-33Cr-8Mo) exhibits a remarkably high corrosion resistance than existing nickel and iron-based alloys.
