Production – Completion – Stimulation
Intervention – Well Integrity

I’m Piotr Wilczek freelance petroleum Engineer. I specialise in the disciplines: production, completion, stimulation, intervention and well integrity of onshore wells. My experience ranges from oil to gas wells in shallow and deep formations as well as salt dome caverns.

Throughout my career I’ve been in the field in as a “hand” as a supervisor and an engineer. I’ve been working together with people with a multitude of backgrounds and positions. I learnt that the most important value you can earn in the oil field is trust.

I’m dedicated to finding good engineering solutions throughout my work. For me good engineering is when you reach your goals with minimum effort or If you get the most out of your resources. I always try to live up to one of those principles.

PVG as an exploration project management company consults me for expertise with completion and well testing topics. They also consult me about well site operations challenges, E&P service providers and well production.

“In three projects Piotr provided valuable support to DEEP, including WELLCATTM modelling of operation modes of gas storage caverns, analysing the failure of sub-surface equipment and developing repair options for a gas storage cavern.”

For Engie E&P Germany I was guiding a young new Engineer in Produktion- Completion and Workoverengineering apsects. I also calculated ESP-Pump designs and a reviewed current workover projects in northwestern Germany oil fields.

For HammGas I’m engineering well completions for exploratory gas wells. I calculate tubing and casing designs and design well test programs. I support their operations as an engineer on site

For LaenhagenGas I’m engineering well completions for a exploratory gas well. I calculate tubing and casing designs and consult the project managers on completion and testing aspects.

E&P Experience

Completion, Testing and Intervention Engineer, GDF SUEZ E&P Deutschland, Lingen
January 2011 – April 2015

I was designing well completions, drill-stem tests and well stimulations. My responsibility was to find a safe and sustainable way to deliver hydrocarbons to surface. To ensure this I was actively in discussion with reservoir and drilling engineers. I was challenged by management before budgets were approved. I was active in the procurement process and responsible for proper vendor selection. I verified my designs with WellCat and wrote work programs for our supervisors. I ensured that our projects were granted approval from German mining authorities. During operation I was on site and took over supervision on challenging work steps. While on site I was a “responsible person” as defined by the German Mining Law.

For GDF SUEZ I was working with different drilling and completion rigs, coiled tubing, slick- and E-line units. The wells ranged from shallow oil to deep gas wells as well as HP/HT exploration wells. All of those were onshore.

Within the completion department I developed a new information management structure. It included a reporting system and a document management system. For my fellow Completion Engineers I was the focal point in WellCat.

I was leading the German Young Professionals chapter of GDF SUEZ. I founded an annual YP Main Event that focused on networking and soft skills development and organized multiple networking events for the YPs with senior management.

Field Engineer, GDF SUEZ E&P Deutschland, Hamburg
April 2009 – December 2010

My main responsibilities were planning, organization and supervision of workover operations in a gas storage reservoir and a depleted oil field. I selected the technical approach, purchased necessary surface and downhole equipment, supervised the contractor at the rig site based on the requirements of the German Mining Law and enforced safety.

I was also in charge of surface engineering interventions. My responsibility included supervision of pipeline maintenance, renovation of old production sites as well as abandonment.
