“…It impacts on well productivity and injectivity (Bryne and Rojas, 2013) and needs to be mitigated for the conduction of a successful exploitation project. This phenomenon can occur due to either particle invasion, fines migration to the porous media, chemical precipitation, organic deposition, or pore collapse (Liu and Civan, 1994).…”

Nanoparticles (NPs) are currently being studied as a drilling fluid additives especially for application in very lowpermeability formations such as shales. Application for conventional permeable rocks is still a subject of discussion. In this work, successful application of in-house prepared iron-based nanoparticles (NP1) and calcium-based nanoparticles (NP2) to reduce filtration loss in conventional permeable media has been experimentally quantified for oil-based mud (OBM) utilizing the high-pressure high-temperature (HPHT) filter press at 500 psi and 250°F. Ceramic discs were used as the filtration medium in this application to test the performance of the NPs and glide graphite as a conventional lost circulation material (LCM) for porous media. These experiments were carried out in the presence of graphite at low and high concentrations. Filtration reduction trends were observed and a reduction up to 76% was achieved. API filter press was also used to investigate the behavior of NPs and graphite under low pressure and temperature conditions (LPLT). NP1 and NP2 at the two graphite concentrations showed a reduction up to 100%. NP1 gave higher reduction especially at low concentrations under HPHT conditions, while NP2 yielded significant reduction at high concentration under HPHT. These trends were reversed under LPLT, giving a new insight on NPs performance under different pressure and temperature conditions. At HPHT and LPLT, the effect of graphite as a filtrate reduction agent is less significant as the NPs concentration increases. High graphite level had a positive effect on filtration reduction in combination with NP1 at HPHT and LPLT. This was not the case for the blends containing NP2 at HPHT. The effect of NPs and graphite was tested individually showing a different performance compared to the combination of them. Impact of NPs and graphite on rheology was also quantified allowing identification of the more sensitive parameters in the blends. It is concluded from this study that blends containing NPs and graphite can be successfully implemented in OBM to minimize formation damage in porous media.

“…The data should never be simply or directly ЉtranslatedЉ in to well performance predictions. But with careful interpretation and as illustrated in previous publications, upscaling is possible (Byrne and Rojas 2013). The lack of oil injection outlined in some of the Example 2 tests above needs no upscaling.…”

Completion design in water injection wells has received a lot of attention in recent years. With increasing deployment of sand control and the desire not to fracture with water injection, a much greater emphasis needs to be placed on selection of the optimum drilling, completion and clean-up fluids sequence compliant with the completion hardware.One tool available to help with the selection process for fluids for drilling and completion is laboratory simulation testing. If performed properly and with attention to the detail required to simulate fluids and hardware, these tests can be employed to predict and optimise well performance.Taking different examples from different field developments we demonstrate the process of test design and propose some interesting amendments for future test designs. We cite some examples of low or no flow in the laboratory and discuss the implications for real well design and geometry. We also challenge some long held assumptions on the ЉbestЉ fluids to use for open hole water injection wells.The paper adds to industry knowledge on this topic and to the development of more representative and revealing laboratory tests. Using real examples from well planning and the subsequent well performance we illustrate the importance of using available tools to help in the design of wells.

Drilling high quality wells requires the use of high-performance drilling muds that can support and protect the wellbore during the drilling process. Drilling mud will create an internal and external filter cake to protect the well during drilling. Although the external filter cake is usually removed before or during cementing jobs, the internal filter cake remains in the near-wellbore formation throughout the life of the well. As thermal well design relies on maximizing the heat delivered to the reservoir, minimizing heat losses to top formations while also protecting casing and cement layers is mandatory. A literature review shows that the effects of temperature on drilling fluids or cements have been intensively investigated. For example, high temperature generates a decrease of rheological properties of drilling muds, as well as increasing fluid loss. When heat transfer estimations are required, the drilling mud properties are not important, unless a thick filter cake is considered. This is why laboratory investigations on filter cake thermal capacity and conduction, together with theoretical estimations of the effect of filter cake on the wellbore heat transfer process make the subject of this paper. For this, the overall heat transfer coefficient has been revisited and additional effects of cement layers and filter cake have been incorporated. The results show that conventional water base muds can reduce the heat transfer from and to the wellbore. Two mud samples have been tested and an increase of the thermal conductivity with temperature is observed. Adding barite to the drilling mud will increase the thermal diffusivity of the filter cake. The thermal diffusivity of the drilling mud is higher than that of its produced filter cake, but can change the heat distribution in the well and the cement temperature levels. Such effects, together with cement layer conductivity and size are usually neglected in conventional heat transfer models and a reassessment of conventional models while considering such parameters is presented in this work.
