... these challenges, an accurate simulated lockup depth is estimated using historical data to identify the required pull force. The CT slim tractor (2 1/8-in.) was chosen as the optimum tool to provide the required pull force, as well as pass through the minimum ID restriction of the well. Specially designed tapered...

... for a reentry by drilling out cement plugs set below the mudline inside the 9⅝-in. outside diameter (OD), 8.535-in. minimum inside diameter (ID), casing and permanently abandoning the wells by isolating the annular space that communicated with the open hole and extended to the mudline. Operations had...

... Abstract The case studies performed in the Middle East and South Asia region shared in the paper reflect the requirement of production/injection enhancement in challenging downhole conditions. Larger tubing diameter, limitations of minimum ID to deploy bigger OD tools, low bottom hole pressures...

... in the casing, or to know the minimum internal diameter (ID) and pressure ratings of the casing. But evaluating the outer (second) casing geometry is a completely new idea and yet very important for many reasons. If the outer pipe is deformed, it will eventually cause the inner pipe to deform, compromising...

... isolation being discussed in a separate paper). Last paper gave insight about plug passing through a minimum ID of 2.3" and set in a 7" production casing. After this campaign, more candidates with plug setting section of 9-5/8" Casing & 4-1/2" Screens were selected. Plug setting with Coil Tubing & E...

... was the inherent risk of permanently damaging the formation. The existing completion design required the isolation plug to pass through a minimum ID of 2.3" and set in a 7" production casing. For this reason, high expansion ratio retrievable inflatable plugs were proposed. The waxy nature of the reservoir fluid...

... that no formation damage would be sustained. The operation had to be run from a semi-submersible platform that was set in a water depth of 430 ft. (2 nd d job performed in a water depth of 968 ft.) The gun assembly would have to pass through a 2.81-in. minimum ID. Introduction For twenty years...

.... A majority of the through tubing sidetracks have been drilled using conventional monobore or through-tubing whipstocks in multiple configurations. CTD has been limited to the size of the tubing or minimum internal diameter (ID) that a whipstock can pass-through and the ID of the tubing, liner, or casing...

... milling job. Several operational challenges, such as excessive corrosion at a minimum MHA ID, pitting on bottomhole assembly (BHA) components and erosion on ball seats, erosion, and degradation of elastomeric seals at a BHST of 400 °F, were observed. These adverse effects were avoided with engineering...

... (minimum ID 3.2") and the 2 nd build up was at 3790-3820 mBRT (minimum ID 2.9"). This scale restricted the reperforating tools from reaching the targeted zone as 89% of the major gas contributor layers were below the 2 nd build up. Scale milling was planned to allow 3-1/8" gun (with possible swelling...
