Proceedings Papers

Paper presented at the ADIPEC, November 4–7, 2024
Paper Number: SPE-221963-MS
... Figure 5 shows this idea in practice. A risk of early injection water breakthough was identified at Well D based on its PLT profile and the ILT at the offset injector. Wellwork interventions were done at both injector and producer to improve the conformance profiles – as seen in the before...

Paper presented at the ADIPEC, November 4–7, 2024
Paper Number: SPE-222035-MS
... Abstract Polymer injection is now a mature EOR process, and numerous large-scale expansions are currently underway while new projects are being designed all over the world. Curiously, one of the basic design questions still remains highly controversial: what is the optimum viscosity that should...

Paper presented at the ADIPEC, October 2–5, 2023
Paper Number: SPE-216133-MS
... on displacing the OBM from the open hole with a solids-free weighted fluid that can be safely injected in the formation and that can also break down the filter cake for lower pressure stimulation operations and subsequent higher productivity due to less skin damage. Filter Cake Breaker Basics After...

Paper Number: SPE-216187-MS
... a straight, vertical well is injecting pure CO 2 to a depth of 2500m with a reservoir pressure of 8 MPa, using a 4.5-inch tubing. The initial temperatures at the surface and in the reservoir are 5 and 70 degrees Celsius respectively. To control the injection process, a choke has been installed at the well's...

Paper Number: SPE-216673-MS
... Abstract The paper presents a unique case study on injectivity tests done in the Kingdom of Saudi Arabia to prove the concept of Carbon Capture, Utilization, and Sequestration (CCUS) capability. It describes the design of surface and downhole testing systems, lessons learned...

Paper presented at the ADIPEC, October 31–November 3, 2022
Paper Number: SPE-210919-MS
... on the often-neglected challenge of inaccessible wellbores. We have successfully developed onshore storage that, by the time of the conference, will have injected over 7Mt of CO 2 sourced from decarbonisation of hydrogen manufacture. In the UK we developed and submitted storage permit applications, and full...

Paper presented at the ADIPEC, October 31–November 3, 2022
Paper Number: SPE-211381-MS
... The Aim of acid stimulation is to remove near wellbore skin and to create wormholes thus improve well injectivity. Abstract In one of north Oman matured carbonate water flood field (Block A), acid matrix stimulation treatments are usually performed by Well and Reservoir Management team (WRM...

Paper presented at the ADIPEC, October 31–November 3, 2022
Paper Number: SPE-210796-MS
... The surface injection pressure is usually low for this kind of scenario, and it will be the corresponding value to the temperature in the saturation line (as the CO 2 is in two phases gas/liquid). The results of simulation models and analyses of the well elements indicate the requirement...
