This study aimed to address the challenges and strategies to determine the critical rate of CO2 injection into a carbonate depleted gas field. In this research, the critical rate is the maximum allowable injection rate before formation damage initiation. The cause of formation damage could be due to in-situ mobilization or trapping of migratory fin...

When developing a high CO2 field, oil and gas companies must consider the best and most economical carbon capture and storage (CCS) plan. After considering the distance of the storage site and storage capacity, PETRONAS has identified 2 carbonate fields, known as X Field and N Field in East Malaysia as the potential CO2 storage site. Interestingly,...

In line with PETRONAS commitment to monetize high CO 2 content gas field in Malaysia, C Field which is a carbonate gas field located in East Malaysia's waters with approximately 70% of CO 2 becomes main target for development because of its technical and economic feasibility. Injectivity has been determined as one of the key parameters that determi...

PETRONAS is interested in monetizing X Field, a high CO2 carbonate gas field located in East Malaysian waters. Because of its location (more than 200 km from shore) and the preferable geological formation of the field, reinjection of produced CO2 back into the field's aquifer has been considered as part of the field development plan. To ensure feas...

We conducted relatively long duration core-flooding tests on three representative core samples under reservoir conditions to quantify the potential impact of flow rates on fines production/permeability change. Supercritical CO 2 was injected cyclically with incremental increases in flow rate (2─14 ml/min) with live brine until a total of 7 cycles w...

There are a number of additional challenges in the development of high CO2 content gas fields. To meet the requirements of the Kyoto Protocol and Paris Agreement, an efficient means to deal with the produced CO2 such as re-injection into the reservoir for sequestration is required. With the intention of developing such high CO2 gas fields, PETRONAS...

PETRONAS has been proactively working to manage naturally produced CO2 from offshore gas field. The field has the highest in-situ CO2 content (~70%) in the region. The reservoir is a Miocene age carbonate build-up, calcite dominated and overlain by a clay-rich cap rock. The reservoir is extremely heterogeneous with porosity between 17─ 40% and perm...

In the current climate, of oil price slump, native sampling and data acquisition are deemed uneconomical as oil and gas companies adopt cost rationalization to sustain business models. Exploration and development data which were previously overlooked are now being sought to gain critical. Cuttings, collected during drilling, can provide overburden...

PETRONAS has embarked on Research & Development (R&D) of Carbon Capture, Utilization and Storage (CCUS) related technologies since 2011. The main purpose in pursuing R&D in this area is to monetize high CO2 gas fields through technology development. At initial stage, area that has been focusing were on capture, transportation and storage only. Late...
