Experiment Protocol Petroleum Engineer in Uzbekistan Tashkent –Free Word Template Download with AI

Project ID: UZ-TASH-PE-2024-001

Location: Tashkent Region, Uzbekistan (Uchquduq Field Pilot Site)

Lead Discipline: Petroleum Engineering

Date of Issue: October 24, 2024

Status: Approved for Field Implementation

This Experiment Protocol outlines the technical procedures, safety measures, and data acquisition strategies for a pilot-scale Enhanced Oil Recovery (EOR) project utilizing polymer flooding. The project is situated in the Tashkent region of Uzbekistan, a critical hub for the nation's hydrocarbon production. As a Petroleum Engineer, the primary objective is to evaluate the efficacy of high-molecular-weight polyacrylamide injection to improve sweep efficiency in mature carbonate reservoirs.

The specific goals of this experiment are to:

• Determine the optimal polymer concentration for the specific salinity and temperature conditions of the Tashkent basin reservoirs.
• Quantify the incremental oil recovery factor compared to conventional water flooding.
• Assess the impact of polymer injection on reservoir pressure maintenance and wellbore integrity.
• Ensure compliance with the environmental regulations of Uzbekistan regarding chemical injection and produced water management.

The scope of this protocol covers the entire lifecycle of the pilot test, from laboratory core flooding simulations to field injection operations and subsequent monitoring. The work will be conducted by a multidisciplinary team of Petroleum Engineers, geologists, and chemists based in Tashkent. The experiment focuses on a specific 5-spot well pattern within the designated pilot area.

3.1. Laboratory Phase

Prior to field implementation, core samples extracted from the target formation in the Tashkent region will undergo rigorous testing. The Petroleum Engineer will oversee the measurement of relative permeability curves and capillary pressure. Rheological tests will be performed to determine the viscosity of the polymer solution under reservoir conditions (approx. 60°C and 150 bar). This phase is critical to calibrate the numerical reservoir simulation models.

3.2. Field Preparation

The injection wells must be prepared to handle the higher viscosity fluids. This involves:

• Installing polymer-resistant pumps and surface piping.
• Conducting wellbore integrity tests (casing pressure tests) to prevent leakage into shallow aquifers.
• Establishing a dedicated mixing and injection facility on-site in Tashkent.

3.3. Injection Procedure

The injection phase will proceed in three stages:

1. Pre-flush: Injection of 0.5 pore volumes (PV) of low-salinity water to condition the rock surface.
2. Polymer Slug: Injection of 0.3 PV of polymer solution at a concentration of 1500 ppm.
3. Post-flush: Injection of 1.0 PV of formation water to push the polymer slug toward the production wells.

The injection rate will be maintained at a constant rate of 50 cubic meters per day per well, monitored continuously by flow meters.

Accurate data collection is paramount for the success of this experiment. The Petroleum Engineer will utilize the following monitoring techniques:

Parameter	Measurement Method	Frequency
Injection Pressure	Downhole and Surface Gauges	Continuous (Real-time)
Produced Fluid Composition	Chromatography and Titration	Daily
Water Cut	Capacitance Probes	Continuous
Reservoir Temperature	Distributed Temperature Sensing (DTS)	Weekly
Polymer Breakthrough	Viscosity Analysis of Produced Water	Twice Daily

Given the industrial nature of the operations in Tashkent, strict adherence to HSE protocols is mandatory.

• Chemical Handling: Personnel must wear appropriate Personal Protective Equipment (PPE) when handling polyacrylamide powder to prevent respiratory irritation.
• Environmental Protection: All produced water containing polymer residues must be treated in the on-site facility before reinjection or disposal, in accordance with Uzbekistan's environmental laws.
• Emergency Response: A spill response plan is in place, including containment booms and absorbent materials stored at the injection site.

The Petroleum Engineer has identified the following key risks:

• Wellbore Plugging: Mitigated by pre-flushing and using filtered polymer solutions.
• Early Breakthrough: Mitigated by optimizing the injection rate and monitoring tracer data.
• Equipment Failure: Mitigated by redundant pump systems and regular maintenance schedules.

This Experiment Protocol serves as the governing document for the polymer flooding pilot in the Tashkent region. The data gathered will be analyzed to update the reservoir model and determine the economic viability of scaling up the EOR project across other fields in Uzbekistan. A final technical report will be submitted by the Lead Petroleum Engineer within 30 days of the experiment's conclusion.
