... infrastructures, potential operational issues, and environmental and regulatory challenges. The decision to appraise an acreage position is very complex and has a high level of risk. One solution to rank and risk candidate drilling locations is a procedure that considers the most critical variables needed...

... Abstract Crush resistance has become a key, perhaps even the singular, parameter used in selection of proppant for hydraulic fracture stimulation operations. The API Recommended Practice 19C (RP19C)—which is identical to the ISO13503-2 standard 1 — lays out procedures intended to produce...

... for the existing rate transient analysis (RTA) procedure. This paper presents a new RTA methodology and associated diagnostic plots to infer all three parameters simultaneously using the information beyond the linear flow period. The analyzed results illuminate optimizing the number of frac stages and well spacing...

... of producing and surface casings. The amount of gas flow rate can vary from a few bubbles to cubic meters per day. However, when the annuli are shut-in, the gas pressure can build to a significant amount. The procedures detailed in this paper are the result of lab studies and postjob reviews of failed remedial...
