The paper cites that horizontal wells have a higher productivity and pay contact per well than vertical wells, thereby reducing the number of wells required to drain the reservoir. Horizontal wells allow operators to take advantage of highly heterogeneous or layered reservoirs, reservoirs with fractures, or water or gas coning...
The paper points put that in the proper reservoir application, horizontal wells yield higher production rates and recovery than vertical wells, yielding attractive economics even though cost may be twice that of vertical wells. Numerous technology advances continue to improve horizontal well performance and broaden application. Among those, under balanced...
The paper points out that during adverse economic conditions, operators must explore all possibilities for reducing operating costs or increasing production. If wells or leases must be shut in, precautions must be taken so that production can be cost-effectively regained when wells are brought back on line. Decisions to shut...
