One of the key benefits to deployment of TerraSlicing is the predictability of TST application to the asset. MOST IMPORTANTLY, are the well logs, any data files, and production history, formation, reserve, and reservoir details. As with any project, the more knowledge the TST engineers can study, the more accurate the results. Virtually any well can be enhanced, and we TST engineers can determine if a project is viable by examining the well data and past production. The following is a list comprehensive "wish list" of useful data which can be provided to enhance application of TST to a given Asset. We recognize that often much of the data is unavailable, however what can be provided will assist the engineers in evaluating a target property.
A. Geological /
1. Rock type, rock analysis, sample of rock for destructive testing is desirable. 2. Hydrocarbon analysis, including viscosity, sour chemicals, scale, asphaltenes, paraffins. 3. Water analysis, including specific conductivity and mineral, salt and trace metals content. 4. Every and all logs run on well, at any point in time in history of well, including electric / resistivity (DIL), neutron porosity / density
(CDNL), mud, oxygen, sonic, computer log, etc. 5. Temperature of target interval(s), but a temperature log is helpful. 6. Isopach map or other contour map or other seismic data interpretation (top and bottom). 7.Porosity stress matrix or tectonic stress data. 8. Initial and current reservoir pressure.
1. Drilling / daily reports or drilling summary. 2. Bit type(s), size, speed, bore hole characteristics. 3. Composition, pressure balance, pH, weight, working muds / fluids / chemicals used, etc. 4. MWD data if available. 5. LWD data if available. 6. Deviation – slope and orientation of target interval.
1. Casing type, size, grade, centralizers, etc. 2. CCL (we do not like to slot through joints and this will tell us where they are). 3. Cement type, amount, mix, cement bond log if available.
1. Rock stability analysis if any. 2. Casing liner, gravel pack type, size, grade, centralizers, if any.
1. Treatment reports – type of treatment – perforation, stimulation details – shot, acid, frac etc. 2. Frac report details – quantities & compositions of materials, rates, pressures, times, etc. 3. Flow testing or other testing – all results, methods of testing, esp. testing by stages, if any. 4. Reports for 1 – 3 (Completion) for all subsequent re-works or re-stimulation efforts. 5. Down-hole Logistics 6. Down-hole production equipment & surface production equipment. 7. Well-bore diagram.
1. All records for rates, pressures – all fluids (inc. gases), on daily or weekly basis, if possible. 2. Balancing and/or overproduction status that occurred at any time.
D. Independent Analysis
1. Any independent calculations – drainage radius, gross/net pay thickness, pay/acre. 2. Independent reservoir analysis or model if available, including initial reservoir pressure, skin factor, permeability, in-place
hydrocarbons, drainage area, etc. 3. Any other notable geological / geophysical, engineering, or operational details. 4. Any decline rate analysis, by stage if possible, and not by commingled production. 5. Any previous life projections or analysis, by material balance or decline curve. 6. Reserve to production ratio or analysis. 7. All analysis to include calculations, please.
