Course Description

Acid Stimulation Techniques Training Course

This course is designed to help perform acidizing on a well candidate in a logical step-by-step process and then select and execute an appropriate chemical treatment for the oil/gas well. The subject matter is practical in intent and avoids the more complicated acid reaction chemistries. Effective acidizing is guided by practical limits in volumes and types of acid and procedures so as to achieve an optimum removal of the formation damage around the wellbore.

Course Objectives

To provide reasonable procedures and guidelines and to offer cautions suggested by particular formation compositions and reservoir conditions. At the end of the course delegates will learn about the many processes involved in acid stimulation operations, about acidizing equipment and how to plan and execute an acid job.

Who Should Attend

Drilling, completion, workover and production engineers and managers. Reservoir and geology
engineers, field maintenance supervisors and operators. Service companies and equipment
manufacturing engineers. Safety engineers and personnel selected by their companies for attending special training courses.

Heavy Oil Upgrading Training

As the supply of light crude oils decreases, the global oil supply will move towards the use of more heavy crude oils (below 30 API) and an increased production of heavy oils (below 22 API) and extra heavy oils (below 10 API). This is part of the forecast growth of unconventional sources, such as heavy oils, together with tight oil and biofuels, that is needed to meet projected market demand for transportation products (gasoline, aviation fuel and diesel). In the case of heavy oils, this requires growth in the use of “bottom of the barrel” technologies to upgrade these heavy feedstocks to distillates for use in the transportation products. Both crude oil residue and unconventional heavy oil upgrading technologies will grow in importance as part of meeting this challenge. This course is aimed at engineers and chemists who work in the hydrocarbon industry and need a broad understanding of conversion technologies that will be needed to meet the increasing use of heavy oil feedstocks in the future. The course will give a brief overview of the key feedstock properties as future oil supply changes and the challenges that this presents to the refining industry in meeting the market product demand slate. The course will include a technical overview of current and, where appropriate, emerging upgrading technologies. For each technology, the following will be given: a brief process description. key feedstock and product qualities. reactor and catalyst system parameters. product slate and key constraints / limitations. Market outlook and economic factors will also be addressed.

Well Engineering For Non-Well Engineers Training

Ever wondered why, throughout the design of a well, objectives, trajectory and casing specifications are often changed several times, leading to unnerving loss of team-time, to changes in cost estimates and to procurement issues? Is it sufficient to have a clearly mapped well design process, in order to avoid the shortfalls that will lead to re-designs and late changes, with cost and safety consequences? Or instead, wouldn’t the well design process be swifter, if all the subsurface professionals knew what key decisions and data they are required to provide, at what point and for what design decisions?  Which means, if they could see the process from the eyes of a well engineer? The purpose of this course is to explain what the engineering of a well entails, what the design decisions are, the reasons behind them and how the subsurface data are used in the well design process, with what consequences and what impacts on the well. To do this, after giving a brief description on the mechanics of drilling a well, the course will mainly focus on the well engineering aspects related to the data coming from the subsurface team; the course participants, through technical explanations and design exercises, will “become” well engineers for three days and this will help them, once back to the office, to be more aware of the importance of their outputs to the well design process.  They will also learn to read drilling reports, which is a skill that will help them be more actively involved in the offsets reviews and in following the wells currently being drilled.

Coiled Tubing and Its Applications Training

This five-day (5) training course covers conventional CT workover and completion application including CT drilling technology and coiled-tubing drilling hydraulics. It presents coiled tubing (CT) as a tool for workover, drilling, and completion services. It provides an overview of the properties of CT (mechanical performance of CT, including working limits, buckling, and fatigue), its manufacture, the surface equipment utilized for deployment, and subsurface tools for CT applications. Coiled Tubing Operations Coiled tubing is chosen over conventional straight tubing because conventional tubing has to be screwed together. Additionally, coiled tubing does not require a workover rig. Because coiled tubing is inserted into the well while production is ongoing, it is also a cost-effective choice and can be used on high-pressure wells. There are a number of well intervention operations that can be achieved via coiled tubing. These include cleanout and perforating the wellbore, as well as retrieving and replacing damaged equipment. Additionally, coil tubing drilling is now implemented in niche-areas and in particular in association with underbalanced drilling. Advances in coiled tubing allow for real-time downhole measurements that can be used in logging operations and wellbore treatments. Hydraulic and acid fracturing, can also be performed using coiled tubing. Furthermore, sand control and cementing operations can also be performed via coiled tubing.
