We’ll Get You There.

IntroductionPetroxin provides multiple world-class integrated oil and gas service packages. Services are provided in the areas of exploration, development, production and facilities, and decommissioning.

Our services actively evaluate multiple technologies to reduce the environmental concerns associated with tight oil and gas production from onshore and offshore fields, while still providing economical production rates and recoverable reserves.

Petroxin LtdPetroxin prides itself on ingenuity, commitment and creativity. These qualities are distinctive features found in Petroxin employees. Our core strength is derived from our ability to integrate multiple disciplines and expertise from staff. We transcend that professionalism and target project-based teams that deliver solid results for clients time and time again.

Petroxin seeks both physical and intellectual challenges to reach the highest safety and environmental standards. Petroxin believes that standards and best practices exist for a reason. We continually train staff to ensure quality is met consistently and actively. In addition we participate in the development and know-how of countries O&G practices. These where Petroxin provides O&G services in, to influence positive value-added practices.

Unlocking the previously thought unreachable resources is Petroxin’s priority. We focus on creative exploration and production techniques to provide solutions that deliver results

Integrated petroleum services Our extensive capabilities and experiences help us to administrate the processing and enhancement of development management through the entire O&G project lifecycle. We are able to execute any project from initial concept generation, through all the phases of engineering, on-going operations support and eventual abandonment activities.

ExplorationThe exploration team within Petroxin provides highly experienced O&G specialists. These specialists have worked on multiple international projects to provide us with a valuable collective experience. The team consists of geologists, geophysicists, petrophysicist, engineers, and energy economists who support our exploration activities.

Field developmentField development and planning expertise is at the heart of Petroxin services. We adopt a strict methodology to obtain the optimum field development from the viewpoint of scenarios. Our technical professionals outline the reservoir characterization, risks & uncertainties and feasible product export routes for field development.

Production and facilitiesOur services includes products, tools, and equipment to maximise and extend the production life of the reservoir. We develop cutting-edge approaches and provide streamline simulation capabilities to apply Enhanced Oil Recovery (EOR) at existing and mature reservoirs for Maximising Economic Recovery (MER).

Field decommissioningWe are experienced to provide reliable and cost-effective decommissioning & demolition design services. These are customizable to client preferences and schedule.

Software developmentA Highly-skilled Software Development Team provide multiple producing reservoir and production engineering software applications and packages.

High level advisoryPetroxin offers high-level advisory and energy market analysis in order to identify the regional opportunities and maximise the value chain. For example, Petroxin UK’s gas market analysis investigates the nation’s energy supply-demand cycle. This unveiled multiple opportunities across a timeline, to aid clients in strategic development.

Field developmentPetroxin provides services to realise fundamental project aims, deliverables and can develop prospects. We can provide custom field development strategies. Petroxin determines resources with confidence by the adequate preparation of surface and subsurface properties alongside being able to provide detailed interpretations.

Our expertiseWe provide integrated services in O&G field development projects from the initial planning stage through to the detailed planning and installation phase.

Our Geoconsultants along with reservoir engineers provide assessment and management of risk for engineered systems and geohazards by acquiring and processing the Geophysical, Geotechnical and reservoir data to create static and dynamic reservoir models.

Our environmental services include environmental impact, liability assessments and compliance and effects monitoring are provided by our environmental specialists on both onshore and offshore O&G projects. Petroxin also provides environmental support for directional drilling, pipeline routes, pipeline plants and seismic hazards analysis.

Our valuesPetroxin may help accelerate field development project schedules and consider the challenges and risks associated. We target smoother integrated services to derive direct benefits to clients.

Field development servicesPetroxin delivers a very distinct understanding of geological, hydrocarbon reservoir and subsurface conditions. Our skilled resources can interpret, model, design and execute from data that is contributed during the course of O&G field development. This allows our clients to concentrate on their business strategy and proceed with technical solutions on trustworthy measurements and assessments that we can provide.

Concept planning Petroxin Provides various scenario simulations based on the outputs of reservoir engineering analyses, incorporated with G&G. The results apply to economic assessments in master development plans and redevelopment projects.

1. Well design optimisation, formation integrity testing and drilling

2. Subsea template and infrastructure installations

3. Flowline pulling and connections4. Pipeline route surveys5. Environmental inspection and

monitoring

Production and facilities Retaining oil and gas production rates and limiting downtime requires a rigorous process of inspection, repair and maintenance, with safety and environmental concerns, among EOR techniques. Petroxin delivers data and support services that optimise and enhance production efficiency whilst reducing the potential associated risks found throughout the oil field life-cycle, late-life strategy and risks pertaining to integrated hub operations.

Our expertise Petroxin delivers EOR techniques, Gas-Lift design and downstream advice for onshore and offshore facilities built on the knowledge gained from the field development projects to sustain production level.

Our technical resources ensure that engineering tasks for enhanced production are achieved reliably and smoothly. We collaborate with a network of capable operators to provide dedicated teams that operate in full compliance with our demanding Quality and HSE standards. These teams operate under our supervision to give you maximum operational reactivity and flexibility.

Our valuesWe realise environmental, safety, logistical and economic influencing factors in the production and export of oil and gas.

Field decommissioningWells that have been used to explore or develop hydrocarbon accumulations at some stage require abandonment as they become unproductive or became uneconomic due to production costs being greater than operating expenses. Petroxin supports the entire decommissioning process for placement of barriers in the well to isolate formations from each other and from the surface.

Our expertisePetroxin’s team experience covers the full well life cycle from design to final abandonment from the late life strategy, cessation of production, abandonment strategies, removal of infrastructure, site restoration and long-term monitoring.
