We Provide Services for:

Unconventional Resources:

We believe production from unconventional resources requires unconventional thinking

Oil and PetrolernThe remarkable growth of Unconventional Resources in North America has already changed the global energy landscape. Outside of North America, significant volumes of unconventional resources provide an impressive boost in the energy supply of any country that is ready to meet the significant challenges to develop them. There are multiple sources of uncertainty in unconventional plays. Some uncertainty results from the extremely small pore size and low permeability of many of these reservoirs and the difficulty to obtain accurate measurements of porosity and saturation. Other sources of risk involve development strategies, infrastructure and commercial uncertainty. At PETROLERN, we pay special attention to the optimized development of unconventional resources. We believe that successful production from unconventional resources requires unconventional thinking. PETROLERN is proud of its contribution to the development of the shale gas resources in the UK. PETROLERN has a strong presence in Pakistan, helping operators to maximize production from tight gas fields. After completing an extensive experimental study on the Vaca Muerta shale, PETROLERN has gained adequate knowledge to help operators in Argentina to develop their shale assets more efficiently and economically.

Deep-water & HPHT Fields:

Easy projects are for experts, we are geeks

oil rig and PetrolernDrilling and production operations in Deep-water and HPHT fields are the most challenging operations in the oil and gas industry. Due to significantly narrow mud weight window in deep water and HPHT environments, safe and optimum drilling, completion and production require advanced knowledge and cutting-edge technologies. PETROLERN’s personnel have extensive experience in modeling and design for deep-water and HPHT operations in Golf of Mexico, North Sea, Off-shore Africa and Caspian Sea.

Geothermal Energy:

We care for clean energy as we do for fossil energy
To maximize the sustainability of Geothermal Reservoirs, especially Enhanced Geothermal System (EGS), and ensure safe and cost-effective subsurface operations such as drilling, completion, stimulation and injection, knowledge of subsurface state of stress, rock properties, natural fractures and temperature is essential. We strive to make the most reliable estimations of these parameters using advanced analytical and numerical models in combination with signal processing and machine learning techniques. PETROLERN is partnered with the University of Utah to leverage its experimental research capabilities and gain access to the Utah FORGE underground field laboratory in Milford for testing developments in EGS technologies. In PETROLERN, we care for clean energy as we do for fossil energy.

CO2 Sequestration:

Environment safety is our red line

Long-term CO2 Storage in geologic formations is a response to growing concerns about climate change resulting from increased carbon dioxide concentrations in the atmosphere. The key to the effective injection of CO2 into the subsurface formations, including depleted oil and gas reservoirs for EOR, is a detailed characterization of the formation properties, in-situ stresses, natural fractures network, seal capacity of cap rock and formation pressure. This is our expertise at PETROLERN. Monitoring, Verification, and Accounting (MVA) to confirm permanent storage of CO2 in geological formations is a significant cost component of any carbon storage campaign and necessary to its success. PETROLERN is researching automated and low-cost MVA solutions to progress carbon storage towards commercialization by providing a reliable and real-time control option over the reservoir as well as reducing the associated costs. Since subsurface monitoring sensors typically generate a huge volume of data, PETROLERN’s solutions address the data management’s bottlenecks including but not limited to insufficient bandwidth, inadequate storage and limited connectivity by means of adaptive data acquisition techniques to enable data compression at sensor location.

Our Success Stories

We strive to turn all our projects into success stories

Drilling in the Bowland Shale, UK

Drilling in Lancashire, UK, for shale gas exploration and appraisal was a disaster with numerous unpredicted drilling problems and non-productive time. The first hydraulic fracturing operation to test the Bowland Shale prospect resulted in a seismic event of magnitudes ML=2.3 which raised many environmental concerns and postponed the project for almost 6 years. PETROLERN’s comprehensive geomechanical study resulted in smooth and problem-free drilling of an S-shape appraisal well and the first ever horizontal shale gas well in the UK at Preston New Road site. The study also provided optimum frac design based on UK regulations and environmental constrains, resulting in multi-stage hydraulic fracturing with no significant seismic events.

Stimulation of a Tight Reservoir in Pakistan

Attempts to stimulate a partially fractured tight carbonate reservoir in South Pakistan indicated that fracturing without an adequate understanding of the in-situ stresses and rock mechanical properties is a huge risk. These initial attempts included a matrix acidizing job followed by a pulsated proppant fracturing job and, eventually, an acid-fracturing job. Despite this, the resulting production rates were unsustainable. PETROLERN’s geomechanical and fracturing study suggested a combined Proppant Fracturing and Closed Fracture Acidizing approach and resulted in the successful completion of a 10-stage stimulation job in a horizontal open-hole of 1,300 m length. This operation was the first of its kind in Pakistan, having a great impact on prospective tight gas developments in Pakistan.

HPHT Drilling in a North Sea Field

Plan for drilling in a North Sea HPHT field was using expensive MPD technology due to a narrow mud weight window. PETROLERN’s geomechanical study suggested a well and casing design that enabled drilling with conventional methods and reduced the cost remarkedly.

Additional HPHT Drilling in a North Sea Field

Drilling in an HPHT field in the North Sea was associated with costly lost circulation and formation collapse problems. PETROLERN’s wellbore stability study showed that minor modification in the well design significantly reduces the risk of wellbore instability. As a result of this study, the next wells were drilled with minimum drilling problems while saving 3 days when drilling the HPHT reservoir section.

Fracturing of a Tight Sand Reservoir in Vietnam

A feasibility study on a tight sand reservoir in Vietnam evaluated that the planned hydraulic fracturing stimulation would be unpreferable due to the current well and completion designs. A add perforation and acid stimulation strategy was proposed instead with large potential incremental production. The study saved millions of dollars for the clients by preventing an operation which would not have any impact on production.

3D Geomechanical Modeling and Compaction Study on a North Sea Field

3D geomechanical modeling and compaction study on a North Sea field revealed that a planned production strategy could cause severe faults reactivation that could potentially risk the reservoir and caprock integrity. An optimum production strategy was designed along with water injection to secure maximum production from the field with no integrity risk.
